Safdie Architects’ Monumental ‘Raffles City Chongqing’ Begins Phased Opening on Historic Chaotianmen Square

Following eight years of design, development, and construction, Safdie Architects is nearing completion on its latest project in China: Raffles City Chongqing, a vibrant complex which combines office, residential, hotel, retail, and recreational facilities across a 22.7 acre site, embedded within the densely developed Yuzhong district.

A phased opening of Raffles City Chongqing commenced in September 2019 with the unveiling of a 220,000 sq.m., five-story retail galleria and continues into early 2020, culminating with the opening of The Crystal, a 300m-long horizontal skyscraper perched at 250m and stretching across four of the development’s eight towers.

Project features

The Crystal
Spanning across four accessible towers, at a length of 280 meters, the Crystal also connects to two of the development’s taller towers via linking bridges. Considered a ‘horizontal skyscraper,’ the Crystal houses 15,000 sq.m. of facilities including gardens, numerous dining options, bar and event space, a residential clubhouse, infinity pool, and hotel lobby.

Enclosed by a glass and steel structure termed a concertina—a serrated profile with an elliptical cross section—The Crystal offers visitors access to natural light, extensive views, and garden settings throughout the year. Metal panels on the west-facing concertina surfaces and glass on the east-facing surfaces afford the guests and visitors with natural light in the morning and shade from the sun in the afternoon.

Retail Galleria and Roof Park
The retail galleria is organized in five stories, topped by an expansive public park that overlooks historic Chaotianmen Square. The three main retail gallerias align with, and are a conceptual continuation of, the principal north-south streets of the city.  

The public park sits adjacent to each of the residential tower’s private gardens, creating a network of green and open space across the development that overlooks the Jialing and Yangtze Rivers.

Towers
The Raffles City Chongqing development is composed of eight towers in total, with six southern towers rising to 250m, and two northern towers extending upwards to 350m. 

SUSTAINABLE ARCHITECTURE AND PEACEFUL SANCTUARY MEET ON A TRANQUIL ISLAND

When architect Nick Troubetzkoy came to St Lucia Island on assignment, he had no idea of the labour of love before him. Or the challenge of creating a green masterpiece on a virgin cliff face for that matter.

However, what struck him most was the peacefulness around him, and the laid back approach to life of the handful of people living there. He resolved to create his ultimate masterpiece right there in the rainforest. He wanted to encapsulate that green beauty in 25 luxury suites, each with one entire wall open to nature.

Caribbean St. Lucia Jade Mountain Club entrance, Pitons in view

With one sweep of creative genius this brought the view into each retreat, while doing away with air-conditioning because it couldn’t work. Instead, Nick Troubetzkoy placed a pool on the rim of each balcony he made of local materials, and with uninterruptable views of Jade Mountain across the water.

The entire resort is an extravaganza of water in ponds and streams and waterfalls that naturally cool the air. Every drop comes from reservoirs fed by island runoff, and passes through a filtration plant as it flows. The only sound is the gentle tinkling of the water. Nick Troubetzkoy explains:

“What I’ve really wanted to do with Jade Mountain is re-evaluate and redesign the basic concept of a holiday hotel experience. I wanted to create individualized spatial environments that would enable guests to forget about the furniture or the fact that they’re in a hotel room.

In essence, to forget about everything but experiencing the psychology of the space on an emotional almost spiritual level. When you combine the water with the air in this way, I believe you unlock a profound potential for an almost magical level of enjoyment and celebration – a magic that may well be the ultimate achievement at Jade Mountain.”

Nick Troubetzkoy developed an affinity for the local people as he planned his great masterpiece on St Lucia Island in the Caribbean. Truly sustainable architecture must improve the quality of their life too, he reasoned:

It was my ambition from the beginning to create an environment that fully captured the island’s beauty. Whether or not I’ve been successful in that effort is up to others to decide of course, but on balance I believe that we have made this part of the island a better place since those early days.

And so he set himself the target to create an organic vision of his dream of personalized guest space, which inspires an almost spiritual emotion. He had no mechanistic plan created on CAD back at the office in the city. Instead, he improvised as he went along to create a dramatic ambience in each sanctuary he built.

He increased the vision of a deserted island by replacing corridors with long, suspended air bridges that were the only way to reach a sanctuary and the magnificent vista beyond.  However, perhaps the greatest attraction is the private bathing pool. Indeed, pure organic water becomes an extension of living here.

Sanctuary pools are raised eighteen inches above the floor to bring them to the level of the bather, who can lounge on the two-foot-wide coping without having to kneel down. They can run their fingers through the water without actually getting wet, or immerse themselves intimately in liquid warmed by the sun.

Everywhere you look in Jade Mountain there seems to be water with iricandescent glass tiles reflecting through. This unlocks a profound potential to get grips with the true magic of the island the Amerindian people called Iouanalao, meaning land of the iguanas.

Construction obeyed in an organic vision after building a structural deck to support the architect’s flights of fancy at succeeding levels. Here is no modular, rectangular structure. Sculpted reinforced concrete follows vision cast directly onto wooden formwork.

Here are few sharp angles either, causing Jade Mountain to appear to flow out of nature. Tens of thousands of cubic metres of concrete were prepared individually in small mixers, because concrete-delivery trucks could not access the site. Instead, they used chutes and wheelbarrows for continuous pours.

A small army of St Lucia artisanal workers achieved this remarkable miracle of love through thousands of hours of back-breaking physical labour. Jade Mountain literally grew out of the ground, says Nick Troubetzkoy. One plank, one nail and one shovel’s worth of sand, cement, gravel and concrete at a time.

If Jade Mountain appears to rise fresh out of the earth, that’s perhaps because first priority was sourcing local materials for responsible finishes. The sand, gravel, and rose-gray, hand-split stone cladding was sourced from the site.

Much of the remainder is from other Caribbean islands, including blush-colored coral plaster finishes from Barbados, arrays of coral tiles from Dominican Republic, and various tropical hardwoods from Guyana.

Artisans worked the timber by hand to extract the subtle colours and textures on doors and other fittings. St Lucia benefited as they discovered their talent and learned new skills for future projects. Every indigenous plant in this symphony of sanctuaries grew in the nursery on site. All surplus material was donated to the locals for their homes.

Obtaining United States Green Building Council LEED certification in 2016 was almost an afterthought, although perhaps it was one of the greatest achievements as it confirmed the project benefited people, planet and profit.

Travelite followed up the next year with gold certification for socioeconomic and environmental aspects, and reaffirmed its recognition in 2018. Jade Mountain and Nick Troubetzkoy’s sister resort Anse Chastanet are still the only recipients on St Lucia Island of this award.

Travelite was particularly impressed by passive lighting and ventilation in the sanctuaries, and the way the external facade captures water for koi ponds and vegetable gardens. They also appreciated the way the natural coral tiles on roof tops and walkways reflect solar heat.

Moreover, they also praised attention to detail during construction. Materials and plants were both sourced locally wherever possible, while an indoor air quality plan, and low-emissive paints and adhesives protected workers who were transported to site using electric transport.

However, Nick Troubetzkoy’s greatest triumph was the lasting gift he gave the island beyond the resort boundaries. The workforce did not only receive surplus construction materials free for use on their own properties. The project was also instrumental in the coral reefs of St Lucia being declared a marine reserve.

Most of all, I prize the spirit of ongoing creation that has for me always been the heart of this beautiful place. If we captured a portion of the island’s beauty and quality of life in our work here and can share it with visitors, then I think we’ve done something of real value.

THE GREEN ARK, FIRST PRIZE WINNER Belgian Pavilion, World Expo 2020 Dubai, United Arab Emirates

The Belgian Pavilion finally unveiled !

During the next World Expo in Dubai in 2020, Belgium will show the world its technological progress to connect minds and create the future. The pavilion, a green ark spanning several levels, is a real jewel of architecture and engineering.
The public tender has just been awarded for the design, construction, scenography, maintenance and decommission. It was won by the BEMOB-2020 group. It includes the Belgian contractors BESIX and Vanhout, the design firms ASSAR ARCHITECTS and VINCENT CALLEBAUT ARCHITECTURES and the scenographers of Krafthaus. It will showcase the techniques, applications, products and materials, which are Belgian or of Belgian origin on both the interior and the exterior of the pavilion.
This building/garden will not just be green on the outside. The preservation of the environment is at the heart of its design and of our concerns, with natural light and ventilation, renewable energies and the smart use of water.

The pavilion will have an exhibition trail, shops selling Belgian souvenirs, places to taste our culinary specialities (including fries, of course) and a business centre, as well as a gastronomic brasserie with a terrace. These are all excellent opportunities for our economic players to show themselves to the world. There is definitely a certain cachet involved in organising a reception in the Belgian pavilion or selling products at our different points of sale, for example.
The pavilion, in the heart of the mobility district, will present our latest technological innovations for bringing people, goods and ideas together. The exhibition premises will offer all kinds of interactive discoveries in the Belgium of the future.
The pavilion is already popular with the business world before it even sees the light of day (the structural work is due to be completed by the end of the year). Many businesses are co-financing it or are contributing to its construction. Contributions by other persons and companies, from SME’s to multinationals, are still welcome!

Jade Mountain Achieves Prestigious Travelife Gold Re-Certification

Jade Mountain Achieves Prestigious Travelife Gold Re-Certification

Nick and Karolin Troubetzkoy, owners of Jade Mountain and Anse
Chastanet, St Lucia, are delighted to announce the hotels’ have been re-certified for the internationally renowned Travelife Gold Certification for Hotels and Accommodations. The sister resorts are the only Gold Certified properties on the island.

Travelife, the sustainable tourism certification system, has re-assessed Jade Mountain and Anse Chastanet’s performance in responsibly managing their socio-economic and environmental impacts. The resorts first achieved certification in 2017
and have worked hard to maintain the title.

Mountain and Anse Chastanet’s performance in responsibly managing their socio-economic and environmental impacts.
The resorts first achieved certification in 2017 and have worked hard to maintain the title.

To gain a Travelife Gold certification, Jade Mountain and Anse Chastanet were assessed against 88 sustainability criteria that take into account the following environmental issues and positive social impacts.

These include:

  • Protecting the environment, through minimising the amount of energy, waste
    and water used
  • Respecting and treating employees fairly
  • Respecting the local community, including its residents and the safeguarding
    of children
  • Protecting the local culture, heritage and wildlife of the destination
  • Supporting the local economy and its businesses

Nick and Karolin Troubetzkoy said of the accolade: “We are absolutely delighted to have achieved Travelife Gold Certification once again, as environmental efforts have always been at the heart of our resorts. It is incredibly important to us that we continue to commit to sustainability and to supporting the local community year-on-year”.

Jade Mountain Resort, St Lucia

Environmental concerns, sustainability and community efforts are at the epicentre of Jade Mountain and Anse Chastanet, with daily practices set up to conserve water and energy and increase recycling efforts.

These include but are not restricted to the following:

  • The design of Jade Mountain reinforces the connection to the natural environment
    with passive ventilation of the rooms and natural day-lighting. Heating and cooling
    of the sanctuaries (rooms) is based entirely on the natural rhythms and cycles of
    the world around us. Not being dependent on artificial cooling or lighting of the
    rooms decreases the use of precious energy resources and minimizes the carbon
    footprint of the resort.
  • The exterior plaza of Jade Mountain was designed to capture all the rainwater in
    Koi ponds and planting areas. The plants are then harvested for use in the resort’s
    restaurants.
  • A natural coral tile was used for exterior walkways and roof areas. It is highly
    reflective and effectively diminishes any “heat island” effect in the local micro-
    climate.
  • Potable water for the resorts is produced by collecting it in a reservoir that was
    originally constructed and used by the British and French to power the water
    wheels that crushed sugar cane. The reservoir was repaired after decades of not
    being used and now collects over 1.5M gallons of water annually that is gravity-fed
    to a state-of-the-art water purification system.
  • Only local, indigenous plants were used in the landscaping, which minimizes the
    need for watering and protects a precious resource.
  • The resorts were the catalyst behind the coral reefs of St Lucia being declared a
    marine reserve to protect this valuable resource.
  • The resorts provide alternative transportation for its employees. On a daily basis,
    shuttles are scheduled hourly to transport workers from the resort to the local
    community, keeping carbon emissions to a minimum.
  • During the construction of Jade Mountain, any left-over construction materials were
    distributed to the local work force for use on their own property.
  • Construction materials that were used primarily came from the island, reducing the
    use of fossil fuels for transportation and the resultant pollution. For example, the
    wood used was harvested from a managed forest.
  • During construction, the workers were protected through the implementation of an
    Indoor Air Quality plan that minimised worker’s exposure to harmful air-borne
    compounds.
  • Low emitting materials (paints, adhesives, etc.) were used throughout the resorts,
    which effectively eliminated volatile organic compounds (VOC’s) that are
    detrimental to a person’s health.

Guests are given the opportunity to learn about the resorts’ sustainability
programmes and actively participate through environmental activities such as reef
cleaning and tree planting.

Stefano Boeri Architetti unveils Smart Forest City in Cancun, Mexico

The new city will host, on a land area 557 ha, 130.000 inhabitants, giving back to nature a large area where it would have been built a shopping district. 400 hectares of green spaces with 7.500.000 plants (of 400 different species chosen carefully by Laura Gatti, botanist and landscape architect) 260.000 of which will be trees, 2.3 trees per inhabitant, and the rest composed of shrubs and bushes. Thanks to the new public parks and private gardens, thanks to the green roofs and to the green facades, the areas actually occupied will be given back by nature through a perfect balance between the amount of green areas and building footprint. The Smart Forest City will absorb 116.000 tons of carbon dioxide with 5.800 tons of COstocked per year.

Smart Forest City – Cancun is the first Forest City of the new millennium, an open and international city whose development is focused on technological innovation and environmental quality. A center for advanced research that could hosts all worldwide university departments, international organizations and companies that deal with very important sustainability issues and the future of the planet. New research and development departments are dedicated to welcome researchers and young students from Mexico and from the best academies and universities from all over the world.

Thanks to the contribution of the German office TranssolarSmart Forest City – Cancun is conceived to be completely food and energy self-sufficient. Surrounded by a ring of solar panels and of agricultural fields irrigated by a water channel connected with a underwater maritime pipe, the City will be deeply characterized by full circular economy.
In particular, water is a key element in the project: it is gathered at the entrance of the City in a huge basin, where there is also a desalination tower, and it is distributed by a system of navigable canals in the whole settlement up to the agricultural fields belt that surrounds the urban area. A series of water gardens are designed to fight floods as a model for resilient landscapes.

This new City is conceived to have a vanguard mobility system: MIC (Mobility in Chain) has proposed an articulated transportation system that allows residents and visitors to leave their vehicles at the edges of the city and rely uniquely on internal electric and semi-automatic mobility.

The urban project of Smart Forest City – Cancun is designed according to Non-Determistic Urbanism. Given the big invariants of urban structure – related to energy infrastructure, mobility and green, to the presence of development and research poles and to the right of each inhabitant to have at its disposal all services at a correct pedestrian and cycling distance – the City grants a great flexibility in the distribution of all different architectural typologies that can be articulated in the five big sectors that the Masterplan defines.

Cairo vertical forest

Stefano Boeri Architetti signs the project of the three green architectures designed for the new capital (the new administrative city) under construction in the south east area of ​​Cairo.

The three “green cubes” – which represent the prototype of an architecture designed to be varied in functional destinations and replicated throughout the entire metropolis – measure 30 meters both in height and in width and house 350 trees and over 14,000 shrubs and evergreens belonging to 100 different species , one third of those living in the entire city of Cairo.

In total, the green area will exceed 3600 square meters, an area equivalent to the building plan.

It is expected that the three new vertical woods, which will be self-sufficient in terms of energy, will be able to absorb about 7 tons of carbon dioxide in a year and produce 8 tons of oxygen.

The three experimental buildings – a hotel and two residential buildings – will be built by the Egyptian manufacturer MISR Italia Properties in a central area of ​​the new capital.

In presenting the three green cubes, which were designed by Stefano Boeri Architetti with the designer Shimaa Shalash as local partner and the collaboration of the landscape agronomist Laura Gatti, Stefano Boeri and Francesca Cesa Bianchi, partner and director of the SBA project, presented the vision of “Greener Cairo”, which envisages six strategies of demineralization of the Egyptian metropolis. In addition to the grafting of green buildings and vertical woods, the ecological conversion of Cairo includes a major campaign to make the thousands of flat roofs in the city green, the “vegetalization” of the facades and the construction of a system of green corridors that will cross Cairo and they will be reunited by a large orbital forest.

According to Stefano Boeri and Francesca Cesa Bianchi: ” Cairo can become the first metropolis of North Africa to face the great challenge of climate change and ecological conversion.”

AQUA – The Balance of Design & Technology

Sinot Yacht Architecture and Design’s 112m Hydrogen-Powered Superyacht Concept Makes Waves At The Monaco Yacht Show

Sinot Yacht Architecture & Design presented yet another groundbreaking concept at this year’s edition of the Monaco Yacht Show with AQUA, a 112-meter fully operational, on liquid hydrogen and fuel cell technology powered concept Superyacht. Sinot shows once more to be able to fuse groundbreaking technology with cutting-edge design.

True Superyacht
Hydrogen, which has been labelled as the fuel of the future for the last decades, finally found its way to the world of Superyachts. The designers at Sinot Yacht Architecture & Design created in collaboration with Lateral Naval Architects, the design for the first 112m LOA superyacht based on liquid hydrogen and fuel cell technology. Now a fully operational 112m concept Superyacht with a speed of 17 knots and a range of 3750 nautical miles is realized, placing AQUA solidly among Superyacht peers in terms of size, performance and usability. Simultaneously meeting and exceeding current superyacht standards, AQUA optimizes hull, energy and space efficiency while providing a maximal superyacht experience at the highest comfort level for discerning owners.

Mindset
Designer Sander Sinot explains how he and his team managed to integrate the hydrogen-electric system capable of catering for all onboard energy needs without having to compromise on esthetics, comfort or usability: “With every project, I challenge my team and myself to surpass ourselves. For development of AQUA we took inspiration from the lifestyle of a discerning, forward-looking owner, the fluid versatility of water and cutting-edge technology to combine this in a 112m superyacht with truly innovative features.” Sinot soon realized they had set themselves an extraordinary goal, so started working on an extraordinary design: “Our challenge was to implement fully operational liquid hydrogen and fuel cells in a true superyacht that is not only groundbreaking in technology, but also in design and esthetics.”

Nature and technology
AQUA is fueled by hydrogen, a unique concept which represents a significant progression towards achieving a new balance between nature and technology. The system is based on the use of liquified hydrogen, stored at -253°C in two 28-ton vacuum isolated tanks. The liquified hydrogen is converted into electrical energy by proton exchange membrane (PEM) fuel cells, with water being the only by-product. All parameters in terms of output, system layout, range and physical dimensions where translated to a complete hydrogen / electric based system. The generated electrical energy is transmitted to AQUA’s switchboards, where it is distributed to provide power for propulsion, auxiliary systems and hotel services. Large batteries buffer the generated electricity to ensure power demands are always met. And thanks to the electric propulsion AQUA is a very quiet superyacht, with very little noise or vibrations. After five months of extensive development, the team of designers and naval architects came up with a design with physical dimensions and operational characteristics that even strengthen the superyacht experience. Sander Sinot: “Reliability and safety are essential in our world. That’s is why we emphasize that we implemented proven technology in a new appliance. Imagine AQUA at open sea, moving water with water?! At 17knots with a range of 3750 nautical miles, which places AQUA solidly in the forefront of its Superyacht peers!”

Privacy and Space
Entering AQUA is entering a world of privacy and space. The spectacular, extremely spacious and beam-wide owner’s pavilion, occupying the front half of the upper deck, offers an abundance of privacy. The pavilion is arranged in a vast open-plan area of interlinked spaces, divided by finely crafted wooden screens providing intimacy and subdued lighting. Both at the starboard and port sides, floor-to-ceiling band windows supply an amazing impression of openness and freedom. The ceiling, at a height that varies from an ample 280cm to an impressive 380cm at the large central skylight, is supported by an intricately crafted wooden structure. The bedroom section is located at the yacht’s axis and offers an endless sightline all the way up to the AQUA room at the bow. The owner’s pavilion is completed with a large bathroom, dressing room and an intimate private spa section. The AQUA room, located at the bow, at the far end of the owner’s pavilion, offers a top-of-the-world feeling and endless views from the best position on board.
Located on AQUA’s beach deck, close to the waterline, the expansive and naturally outfitted VIP state rooms stand out by virtue of their spacious design and highly elaborate furniture. The VIP cabin and other state rooms are focused on openness, luxury and comfort, providing a maximum sense of freedom in a highly detailed minimalist Japanese beach-style setting.
The indoor health & wellness center is a water-world of serenity, where the reflecting waves of the water feature complement the onboard environment with their soft, vibrating motion. With an exclusive hydro massage room, a yoga space and workout floor and a massive, gym-wide hatch which opens to reveal the ocean’s surface at water level, creating the perception of exercising and relaxing on an island in the sea.
Situated at AQUA’s core, the spectacular circular staircase is one of the yacht’s defining features, winding down from the top deck to the lower deck. A true spectacle manifests itself at the lowest level, facing aft, where two vast liquified hydrogen tanks reveal their hexagonal textured surface structure behind a giant façade of strengthened glass.

Curved
The flowing exterior lines of AQUA are inspired by ocean swells – the surge of energy induced by winds and currents, boosted by the gravitational forces that control the ocean’s tides. The curved top deck culminates in a sensational bow with integrated front bow observatory, the AQUA room, as part of the Owners pavilion. The hull is a sculpted overall double curved volume, intersected by the glass band windows, which subdivide approaching the aft stepping down to the water. The raised front profile with a strong forward direction in the design, provides ample space for accommodating all Owner’s, guests and technical facilities. AQUA is configured with a five-deck set up, utilizing forward interior space through the high sheer line which subtly descends from bow to aft. The yacht has been designed to provide those on board with the closest possible proximity to the water. The aft deck features a unique and innovative series of platforms cascading down towards the sea, while a large swim platform allows all AQUA passengers to enjoy the optimal experience of accessing the water at sea level. 

Technical feasibility
Many concepts Sinot Yacht Architecture & Design has presented over the years are in different stages of realization. AQUA is designed for owners who want to take yachting to a next level, with a pioneering design that clearly prefigures the superyachts of tomorrow. AQUA: a new way of yachting.

Heady times for Chelten Homes as they reach goal as certified net-zero builders

It should come as no surprise that Chelten Homes would want to cement a reputation as certified net-zero builders.

Anyone familiar with the Waterdown, Ontario, company would be the first to tell you that going that extra mile is a trait Chelten Homes has long embraced.  And the current net-zero designation of a home at 218 Ascot Place in Burlington is no exception.

“The project at 218 Ascot Place in Burlington has been an exciting one for Chelten Homes on many fronts,” says Marcel Leclerc, president of Chelten Homes. “Our impetus for building this home started with our desire to be certified as net-zero builders.  We believe there are better ways to build a home that provide the homeowner with the benefits of increased climate control within the home and lower operating costs, while at the same time reducing the strain on the environment and our natural resources. 

“With a net-zero home, we all win and we want to be at the forefront of this building practice; and this project gave us the experience we needed.” 

Previously, Chelten Homes made a name for itself by espousing walkable communities, utilizing construction materials from local craftspeople and optimizing livable space.

With 218 Ascot Place, Chelten Homes raises the bar even more.

 “We enjoy being pushed and expanding our experience as builders so we asked the architect [for 218 Ascot Place] to pick a style of home we had not done before,” Leclerc says. “She came up with an impressive West Coast Modern design, which challenged us to think differently, source new and interesting materials, and build differently.  We are very excited with this project and the end result and look forward to being able to refine and grow with the next project.”

To be clear, 218 Ascot Place is a net-zero home, meaning it’s air-tight, well-insulated and energy-efficient and will produce as much renewable energy as consumed, leaving the occupants with a net-zero energy bill and a carbon-free home. 

For example, the first hydro bill for the home, provided by Burlington Hydro, shows s sizeable  energy credit. The energy consumption was 192 kWH and the home generated 842 KWH of energy. It should be noted that the first month included running the home with four occupants, daily use of air conditioning … plus pool maintenance. The custom solar PV system, by the way, is forecast to provide a lifetime savings on electricity of $127,030, according to Bluewater Energy from Guelph, Ontario.

More specifically, here is a list of features that contribute to the overall energy-saving package:

  • 218 Ascot Place in Burlington is a smart home. Everything can be controlled and monitored remotely;
  • Windows are triple glazed fibrerglass;
  • The exterior walls have two-inch R10 rigid foam insulation with continuous thermal break, the interior of those wall cavities are R20 – a total wall R30 value. In addition, two-inch spray foam was applied under the basement slab with continuous thermal break, which prevents heat loss and air leakage – a home’s most inefficient areas;
  • Exterior rim joist cavities were treated with R22 spray foam to eliminate a major source of heat loss;
  • R12 spray foam was applied in the attic with R50 loose fill for maximum energy efficiency;
  • The air tightness was further enhanced by the AeroBarrier envelope sealing technology;
  • Hubbell energy-saving receptacle boxes (complete with airtight gaskets) were installed throughout;
  • There is a complete in-home ozone water treatment and filtration system, which eliminates impurities left over from municipally-treated water, including viruses, bacteria and treatment chemicals.

All in all, Chelten Homes believes the net-zero offerings will continue to complement the competitive advantages the company has over others in the construction industry.

“Chelten is family in many ways,” says Leclerc. “Each employee acts like a leader and is encouraged to be an innovator in everything we do.

“They look upon every task as how will it impact other members of the Chelten family, how it will benefit a project and, ultimately, how will the customer benefit. We like to under promise and over deliver.”

That dedication is often supported even more as many Chelten Homes’ team members live close to the communities/neighbourhoods the company plans and develops.
“So that means we develop a personal connection to each and every project,” says Leclerc. “We practice what we preach on a daily basis. We are never satisfied with a job well done.”

Greening of King Township Municipal Centre symbolic of sustainable push by +VG Architects

+VG Architects set lofty green goals and they consistently back them up with on-target results.

 The company, with offices throughout Ontario in Toronto, Brantford and Ottawa, makes no bones about it when it comes to establishing a new standard for all buildings – the intent is to bring green initiatives and sustainability practices to the mainstream.

 They accomplish that in a variety of ways, seeking to broaden their impact … and not just with specialty buildings or clients who have ample budgets to pursue LEED certification.

 “Since municipal clients are held accountable for taxpayers’ hard-earned money, they’re often conservative in their approach to innovative ideas, including green initiatives that they may not have had much experience with,” says Nicole Konrad, director of marketing in the  +VG Toronto office.  “When money’s tight, relying on tried and tested methods can seem like the most sensible route to take. 


“+VG champions sustainable practices by educating our clients, who can then educate the public. In many cases, green initiatives actually produce cost savings over the life of the project.  I think municipal clients can also find the different energy efficiency rating systems (such as LEED or Passive House) intimidating.  We’re showing them that it doesn’t have to be all or nothing.  It’s better to do something than nothing at all.”

Saying that, often there are projects that are mostly ‘all-in’ with what +VG proposes. A case in point is the King Township Municipal Centre, located just north of Toronto in King City.

Completed in February, the project incorporates many green initiatives such as geothermal mechanical systems and enhanced sustainable site strategies and is anticipated to meet either LEED silver or gold level certification. King Township had outgrown the previous facility and +VG pointed out that the Sixties-era school building had many physical constraints which would limit an efficient adaptive reuse.  As well, the client was told, any selective demolition would be extremely costly.

 As a result, a detailed cost benefit analysis was conducted and it revealed that a replacement building would only present an increase in cost of four percent, so +VG moved ahead with a new building on the site.

 The upshot is that the building has created a new identity and focus for the community, and is perceived by citizens as cost-effective and pleasing.  It should also be noted that the final project was delivered on-time and on-budget.

Thomas Wilson, the project manager and +VG partner, says a defining characteristic with King Township is the presence of the provincially-protected Green Belt natural preserve. With that in mind, +VG was able to reflect the symbolic importance of that reality with the design for the new municipal building.

 The site, Wilson says, is bounded by natural woodland and wetland preserves. He points out that the +VG design enhances these preserves. Some of the features include:

  • Twenty percent of the site designated as woodland restoration;
  • Stormwater management enhancements, such as permeable pavers that reduce water quantity and greatly improve water quality, flowing to the adjacent wetlands;
  • A series of new nature trails around the site;
  • Educational signage describing key aspects of the natural surroundings;
  • And mitigation measures such as bat boxes that support indigenous wildlife and reduce the impact of human development.

“It was also important for this project to lead by example when it came to township values and planning policies related to sustainability,” Wilson says. 

To that end, Wilson said the building included the following components as part of the design:

  • Ground source heat pump system for heating and cooling to reduce energy costs and provide zero greenhouse gas emissions;
  • High-performance building envelope, including high-performance glazing;
  • Heat recovery ventilators and variable speed pumps;
  • And high-efficiency LED lighting systems utilizing time-of-day controls, daylight sensors and occupancy sensors.

Two other +VG projects – Kingston East Community Centre and Township of McNab/Braeside Municipal Offices – provide yet another glimpse into the company’s green approach. 

In Kingston, in addition to enhancing the surrounding area, the community centre will contribute to the city’s goal of reducing carbon emissions to become a leader in sustainability and environmental stewardship. When completed, it will also serve as a learning tool for the surrounding community to understand the importance of building high-performance, energy-efficient public buildings and their impact on reducing greenhouse gas (GHG) emissions.

In McNab/Braeside, less than 100 kilometres west of Ottawa, the new town hall will be constructed using engineered timber products to pay homage to the rich history of forestry and logging in the area and to reduce to overall embodied energy in the building materials used for construction.  Other green features include a ground source thermal field, energy-efficient building systems and a future solar array.

“+VG Ottawa specializes in the coordination of energy-efficiency/GHG reduction studies to assist our clients through the design development stage of their projects,” says Daniel Wojcik, an architect with +VG Ottawa.  “Working closely with mechanical, electrical and sustainability consultants we are able to empower our clients into making informed decisions to reduce resource consumption and GHG output while understanding the capital and life cycle costs to achieve their objectives.”

Chatsworth Fine Homes continues to raise the bar with net-zero ready luxury offerings

Chatsworth Fine Homes has always been known for providing painstaking attention to detail.

What should also be highlighted, however, is that the Oakville-based boutique builder has many years of experience utilizing energy-saving techniques – with one property, in fact, receiving the first net-zero ready designation in the Metro Toronto area.

“We have supported green building for a long time,” says Fil Capuano, Chatsworth’s president. “We feature a strong background in engineering and we see where so many outmoded building practices are still in use today that do not address client concerns of comfort, financial and social responsibility. We have to have an eye on what is in everyone’s mind – climate change. “We have very sophisticated and well-educated clients who have a grasp on what is available today … and they want only the best when building a new home.”

The designated home at 1013 Westdale Road in Oakville – the recipient of the net-zero ready classification – is the latest example of Chatsworth’s embrace of both sustainable building and framing a practical way forward to address climate change concerns.

“The home demonstrates that you can have a fabulous luxury home that doesn’t compromise aesthetics,” says Capuano. “The big news in our market, really, is that we can build a luxury home with no compromises that consumes just over one third of the energy of an equivalent home built to OBC (Ontario Building Code) standards.”

But, as Capuano stresses, Chatsworth is definitely not “new to this.”

Nearly 20 years ago, the Chatsworth team built Chelster Hall in Oakville, a magnificent mansion on the shores of Lake Ontario. One of the largest private residences in Canada, the sprawling property sits on 10 acres with 47,000 square feet of living space – about the same size as the White House in Washington, D.C.  Chatsworth utilized insulated concrete forms (ICF) throughout the build, and Chelster Hall was the recipient of a North America-wide ICF award in 2008. Fast-forward to 2015 and 2017, and you’d see that Chatsworth remained at the forefront of high-performance building, presented with Best Custom Home awards from the Building Industry and Land Development Association (BILD). The 2017 honour was for a home at 129 Burgundy Drive in Oakville; which BILD noted included many environmentally-sustainable features.

“Again, with that project, with utilized ICF from footing to roof,” says Capuano. “It was built to R2000* standards, had triple glass windows with a U value of 1.1, air tightness of 1.4 ACH50, seven kW of solar, plus a 3 1/2 -inch interior furring wall, providing total wall insulation of approximately R-40.”

That home, completed in 2016, had many of the same traits as net-zero, as Chatsworth continued to incorporate environmentally-friendly systems.  As noted, standout sustainable features included a super-insulated envelope, four energy recovery ventilators, the rooftop solar PV system, low-flow plumbing, rainwater collection for irrigation, occupancy sensors, intelligent controls, and LED lighting. The tight envelope, understandably, drastically cuts back on the heating and cooling loads.

The upshot is that everything is balanced by smart engineering and advanced controls to optimize heating and cooling efficiency. With no system oversizing permitted, the gas bill for the home is less than half what it would be for the size of the building.

“The green buzz is everywhere,” says Capuano. “But to deliver on net-zero you must have third party assurance that the performance of the home measures up to the net-zero program’s strict guidelines.

“Many people think that building a larger home with high-quality finishes and luxury options may be wasteful.  But we’ve proven that the net-zero ready program delivers a home that consumes almost 60 per cent less than its code-compliant counterpart and is a major step forward – luxury with a view to economy and social responsibility.

“You can have your cake and eat it, too!”
