Sarah Hall:  Stained Glass & Solar Projects

The Royal Ontario Museum in Toronto conducts bus tours and walking tours of nearby art and architecture. One of these easily outsells all the others, a bus adventure dedicated to stained glass windows and architecture. You might expect the tour’s destinations to be traditional stained glass in churches and cathedrals. In fact, the bus just as often stops at contemporary new buildings with stained glass designs by Sarah Hall. Sometimes the special guest tour narrator on the bus is also Sarah Hall. You may ask what’s new in stained glass? The answer is that there is plenty that’s new, especially if it involves Sarah Hall.

Hall became interested in stained glass at a young age and discovered that it is a very small world, especially in Canada. In order to find in-depth training in the field she journeyed to Swansea College of Art in Wales. She returned and established a studio on Dupont Street in Toronto in 1980, where she and her craftspeople worked for two decades, introducing new ideas in a conservative field. She was interested in combining new building technologies with stained glass.

 

German Engineering

Around the turn of the century she became involved in projects that required her to relocate her fabrication studio to Paderborn near Hanover, Germany. In Germany she could access a larger pool of glass artisans and large size kilns for the ideas she was hatching. In addition, the stained glass industry in Germany has connections with the broader glass industry, allowing for ambitious product development. New ideas include stained glass windows that could be sent to Austria and tempered, as in safety glass; new kinds of glass that could combine art with heat mirror technology, as in R20 insulated office tower windows; and last but not least, stained glass projects that incorporate solar photovoltaics.

Christof Erban is a renowned German engineer who pioneered the concept of placing a solar PV cell between two layers of glass. Many years ago he visited glass painting studios in Germany looking for artists who were interested in working with photovoltaics. While others focused on the challenges, Hall jumped at the chance. The rest is history. Hall’s studio is now at the forefront of contemporary stained glass architecture.  Since moving the studio abroad, her Canadian/German team has been involved in more than 200 projects.

 

Harbourfront Waterglass Project

Sarah has recently completed a project called Waterglass at Harbourfront Centre’s Enwave Theatre, which is expected to open to the public in Spring. The glass is highly artistic, incorporates heat mirror technology, employs NASA’s dichroic glass technique (sandblasted on its back side and laminated so that it is transparent but also highly reflective of UV rays) and on the western exposure, as directed by engineers, includes photovoltaics to capture solar energy.

 

Her team of six technicians created 1700 square feet of a handmade art glass in just three months. It was crafted in the German studio, sent to Austria for heat mirror and photovoltaic laminations and arrived in Toronto ready to install in thermo-panel units.

 

In addition to being a technical marvel, the installation is an artistic and historic gem.

“The client wanted to symbolically reclaim the lake for Torontonians,” says Hall. “We are cut off in a lot of ways and have not built the lake into our thinking as a city.” At first glance visitors will see water, waves, and the silhouette of a ship. On closer inspection they will find much more.

 

Hall researched and photographed the lake’s north shore for months and then began researching images of people, locations and events. The windows contain hundreds of silk-screened archival illustrations of personalities such as swimmer Marilyn Bell, rower Ned Hanlan, structures like the art deco Sunnyside Swimming Pool Pavilion, and R.C. Harris Water Filtration Plant; events including the war of 1812, pandemics, celebrations, political events and families simply enjoying the lake. “The research experience was very instructive,” says Hall. “Much of our waterfront is privatized or otherwise inaccessible. We need to open up the lake to our consciousness, in order to care more about it.”

Wind Tower at UBC

Hall’s team also created beautiful glass for a wind tower or wind catcher at the University of British Columbia. Wind catchers are traditional Persian architectural elements used to generate natural ventilation in buildings. Hall’s stained glass is the central element of a wind tower that completed an underground library at the university’s Regent College. The forty-foot tall wind tower provides ventilation for the library and is a functional symbol of Regent’s commitment to renewable energy. Hall created a luminous column of light, flowing like a waterfall in silvery blue, violet and white. Included in this column is an array of solar cells that collect energy during the day and use it for nighttime illumination – acting as a beacon for the surrounding park.

 

A similar concept was used for the Grass Valley School in Washington. The architect was interested in a sustainable initiative and felt that not enough educational value would result from simply adding solar panels to the roof. Hall created a beautiful artistic glass window for the main stairwell that included PV cells. These were connected directly without inverter or batteries, to a large LED lighting fixture in the main hall. Students soon saw that the fixture was powered only by the sun, glowing brighter and longer on the sunniest days.

High Potential New Solar Cladding

Perhaps the most exciting concept that Hall’s team is working on is a brand new type of solar glass cladding for retail stores and office buildings. Her other projects involving solar have been primarily symbolic or educational, rather than highly efficient in terms of electricity generation. The new product, being developed in partnership with a prominent Toronto architect, aims to change that and collect significant amounts of energy. At the same time it will create artistic canvasses of larger expanses, or entire exteriors of shops or towers, according to client preferences.

 

Subject matter will range from highly artistic to commercial in nature, all rendered beautifully in contemporary glass by a very leading edge artist named Sarah Hall.

Barbara Lawlor – Baker Real Estate

Condominiums meet the needs of today’s bottom-line customer

For Barbara Lawlor, President of Toronto’s Baker Real Estate, the concept of embracing “green” has seen a boom to her business. In fact, the entire condominium industry has developed a consciousness about energy efficiency and green sustainability.

The industry has created an environment that is environmentally responsible, and it has become a key design element in condominiums buildings. Condo ownership has never seen better days.

“In the last three years condominium sales have outpaced low-rise and have taken over 50% of the market – so as a lifestyle choice, it continues to grow, and part of that is the government mandate for vertical growth,” explains Lawlor.  “Let’s face it, there just isn’t enough land within the GTA to meet the low-rise demand, so the best use of space is vertical, and condominiums are becoming more popular. Even young families are venturing into condos because of their convenience, location, transit etc.  And let’s not forget those in transition, like empty nesters and young professionals, who don’t want to deal with upkeep. People lead very busy lives, so the more they can have their needs catered to, the better. In fact, most condo buildings today are like coming home to a luxury hotel, with all the amenities offered under your roof.”

However, the driving force at the end of the day is the bottom line. Educated homeowners have demanded the building industry include energy efficiencies.

“People are afraid of costs escalating. So energy efficiency is part of their checklist.  For example, they really appreciate something like individual metering systems. Whatever will make the buildings more efficient and help defray costs, that’s the key for everybody – what’s it going to cost me?”

Ten years ago, energy efficiency and sustainable living may have been a part of the conversation but the uptake was slow. It wasn’t something that translated across the industry as a whole. “But the industry has stood up and deserves a round of applause in my mind for the tremendous efforts and strides it has made,”says Lawlor. “For instance, we represent the residences of the Ritz Carlton, and they have the Enwave deep water cooling system, which is very innovative and taps into the deep waters of Lake Ontario to heat and cool the building. So there are some very exciting things happening in the city including car sharing, bicycle storage — all of this to cut down on greenhouse gas emissions. In fact we’re selling fewer and fewer parking spaces.”

In Lawlor’s mind, it’s not about green-washing today’s consumer. There has to be a solid green story regardless of where you’re building or what you’re building.

“Buyers are sophisticated, and they want to know that their building is going to be sustainable and function efficiently 10-20 years from now- not just today.”

First LEED Platinum Residence in Greater Toronto

“Swifter, higher, stronger” is the English translation for the original Olympic motto “Citius, Altius, Fortius,” which celebrates the relentless pursuit for improvement in human endeavours, particularly on the athletic field. Rating systems such as LEED recognize achievements in sustainable building. For 72 years the world’s fastest sprinters strove to break the 10-second barrier until 1968, when Jim Hines finally did so; but by 2012 in London seven men ran the final race in under 10 seconds.

“All building projects require passion and commitment from those involved to be successful, but with a sustainable building, these attributes are required in spades,” said Dewson.  “Each and every one who participated in 27 Farnham Avenue held fast to their enthusiasm from the beginning to the end.”

The team included Kyle England, who was Dewson’s Team Leader, Eric Adelman and Matt Brooks of South Park Design Build, Philip Drader of Mindscape Innovations who was the Provider QAD, and Kyle Anders of Greenscape Building Consultants who was the Green Technology & Energy Rater.

The project was a 4500 square foot, six bedroom detached home and scored 96.5 LEED Canada for Homes points for Innovation and Design Process (10/11), Location & Linkages (10/10), Sustainable Sites (17/22), Water Efficiency (6/15), Energy & Atmosphere (25/38), Materials & Resources (14.5/16), Indoor Environment Quality

(12/21) and Awareness & Education (2/3).

In other words LED strip lighting; lots of skylights and big Loewen triple glazed operable windows, a reductive cooling system and six ton geothermal ground source system; 25 bifacial solar panels; a white roof; an energy recovery ventilator; HEPA air filtration, an ultra-insulated envelope with exterior walls and structural framing wrapped with polyisocyanurate foil panels to eliminate thermal bridges; window shim and joist cavities filled with spray foam from soy/vegetable oils and polyethylene from recycled plastic bottles; PIC joints, seams, fixture wells, filter housings, electrical and communication boxes and vent ducts all carefully taped and caulked; Energy Star appliances; no or low VOC paints and flooring; low flow plumbing and dual flush toilets; drip edges, sealing and extra membrane to control moisture and water flow; drought-tolerant native landscaping with no invasive species; a dry well and a permeable parking pad; 80% recycling of demolition waste; reclaimed brick, struts and joists; and more.

Congratulations to Bill Dewson and his team for their Olympian achievement with the first LEED Platinum residence in Toronto. A new benchmark has been set. Now let’s smash beyond it!

Green Development Strengthens Iconic Ottawa Church

CATHEDRAL HILL IS BREAKING GROUND

A groundbreaking ceremony in August marked the beginning of new project by Windmill Developments called Cathedral Hill. It also broke new ground metaphorically, as the project will represent very contemporary achievements in terms of sustainability, heritage, advanced architecture and modern partnerships. Built on-site with Ottawa’s historic Christ Church Cathedral on Sparks Street, it will be an answer to some of the church’s challenges, and it will become the landmark that visitors notice first as they enter downtown from the west.

It combines all the elements of modern condominium living and building: Green technology, stunning natural views from a 20 storey tower, sumptuous design of interiors, courtyards and accompanying townhouses, downtown location advantages,

a walkable, friendly neighbourhood and a community-enhancing development partnership.

NOT-FOR PROFIT PROGRAM

In some parts of the world churches are struggling to redefine themselves within their community and to survive financially. Windmill Developments has created a model that helps such organizations revitalize themselves while remaining viable and becoming more environmentally responsible too.

Cathedral Hill is good example of this idea in action. The church was able to leverage its real estate and key location, and by partnering with Windmill, will increase both its community visibility and the local population base. The developer benefitted from a perfect location for its latest project and the church received prepaid 200-year lease revenue, and should grow, as new owners move into the area.

Today’s non-profit groups are faced with high utility bills, deferred maintenance, and ongoing operational costs. The funds being used for upkeep might be better spent furthering the core mission of their organizations. BuildGreen Solutions, a consulting arm of Windmill, has developed a unique program aimed at optimizing assets of not-for-profit groups, schools and churches and helping them to turn maintenance liabilities into sustainable funding sources.

ENERGY EFFICIENT

In addition, Windmill Developments would have to be considered one of Canada’s greenest builders, and Cathedral Hill one of the greenest projects in Canada. It will be LEED Gold or Silver and is expected to achieve between 40% and 50% more energy efficiency than the Model National Energy Code for Buildings expects from a project with its footprint. It will feature high envelope conservation standards an innovative HVAC system, contemporary water management, and is designed to limit the need for automobile travel.

Cathedral Hill wall sections will be doubly insulated on the inside and on the outside, followed by more exterior insulation, and finally a special cladding material. This achieves overall thermal resistance of approximately R22, far exceeding code, increasing thermal comfort and reducing energy consumption.

Preventing the natural movement of heat toward cooler spaces has traditionally meant adding mechanical heating and cooling, depending on the season. Cathedral Hill’s energy efficient double-glazed Low-E windows are designed to include an insulating barrier, rather than a thermal bridge, between the outside and inside portions of the window frame and between the two panes of glass. This is critical insofar as up to 50% of heat transfer can be via poorly designed windows and doors. Window coatings help control heat gain from the sun in warm temperatures and also keep the heat within the suites in cooler seasons.

VRF HEATING & COOLING

The project will employ a rare and highly efficient heat pump process for heating and cooling. The 200-ton system will use Variable Refrigerant Flow (VRF) technology to regulate the flow of refrigerant between the condensing unit and each of the indoor units in accordance with the capacity requirements of the building. Because the heat pumps will be centrally located, it will be possible to move heat from one side of the building to another, without îı\002778ˇøÚ‹””>having to use fuel to make more heat. Depending on the outdoor temperature and sun exposure, the VRF system will simply move hot refrigerant to where it is needed.

The system’s inverter drive varies the compressor speed to match the building’s heating or cooling load, which is constantly changing. Partial load conditions prevail for more than 90% of operation time and inverter-driven technology takes advantage of this, so VRF systems produce significant energy savings. There is no refrigerant-to-water heat loss as with a chiller system. This means the compressor can maintain a higher suction pressure for more efficient operation. VRF systems also don’t have lengthy metal ducts that cause heat loss. Instead they save energy and allow each indoor unit to operate individually, with separate adjustment of the environment in each area. In addition, VRF system heat pumps are in the

It is also being designed so that excess heat can be moved, as available, to supplement the domestic hot water heating function, further controlling project energy costs. In addition each suite is equipped with a quiet enthalpy-wheel-based Energy Recovery Ventilator (ERV).

GREEN LIVING

Digital metres in the suites will connect the user with environmental conditions and the costs they are incurring. This is a more integrated approach to energy management, and has been proven to reduce energy usage. Suites include Energy Star appliances and all common areas will be lit by extremely efficient LED lighting systems, to reduce the electricity load required by the project.

To minimize unnecessary fresh water use, toilets in the townhouses and on the fist five floors of the tower will be flushed using a rainwater harvesting system. A 125 cubic metre rain harvest tank and 132 cubic metre stormwater overflow cistern will be built into the project.

Cathedral Hill is located near the Gatineau/Ottawa bike trail system. Frequent transit service in the corridor is only a few blocks from its front door. By 2017, the LRT will be complete and a nearby station is expected to be included. Windmill is also in talks with a bike rental service and a car sharing service, either or both of which may be incorporated at or near the site.

High envelope conservation standards, an innovative HVAC system, contemporary water management, limited automobile travel; it all adds up to an almost religious sensitivity to our natural environment. And with its modern church partnership, urban living advantages, innovative architecture and heritage aspects, Cathedral Hill truly is ground-breaking.

 

LiveWall®: New Planted Wall System Achieves Simplicity and Sustainability

Manufacturer of LiveRoof® Introduces a Planted Wall System Designed in Harmony with Nature

Green Walls Should Be Good for Plants: a Conversation with Dave MacKenzie

The team of horticultural scientists, landscape professionals, architects, roofing specialists and green building experts at Hortech, Inc. (Spring Lake, Mich.) who created LiveRoof® — the green roof system proven in more than 600 installations — have launched a new planted wall system, LiveWall®.  In this interview, Dave MacKenzie, horticulturalist and president of Hortech and its LiveRoof, LLC and LiveWall, LLC subsidiaries, discusses some basic questions about green walls and the new LiveWall system.

Q: First, what is the basic benefit of a green vegetative wall?

Transforming an ordinary wall into a vertical green landscape adds a living, organic element to a building. Green walls are visually appealing, inviting and inspiring, healthful, and beneficial to the environment (especially for moderating the urban heat island effect).

Q: What are the basic types of green wall systems?

There are trellis and cable systems and planted wall systems. With the first, a metal trellis structure or set of cables are attached to the side of building and support vines that grow from the ground up. Planted walls have soil (actually, an engineered growing medium) in a set of containers attached to a wall. Thus, planted walls provide soil for the plants all the way up the wall to the height of the installation.

Q: Vines… that prompts the question why not just grow ivy on a wall?

Ivy-covered walls are the most traditional form of green wall. As a horticulturalist and nurseryman, I am reluctant to speak ill of any plant. We grow and sell ivy. But English and Boston ivy both lack colorful flowers. And they can be temperamental and aggressive. In areas of cold winters, English ivy is prone to wintertime dieback. In warm climates, it can be a chore to keep it out of windows and siding. Boston ivy is more hardy but even more aggressive.

Even when vines are grown on a freestanding trellis or cables adjacent to a wall, vines have limitations when it comes to green wall aesthetics, design and function.

Q: Such as?

There is only so much creativity that a landscape architect can bring to a green wall design when constrained to using only vines. I mentioned the lack of colorful flowers with ivy. In addition, it can take years for vines to grow and climb up to make an entire green wall green. A planted wall can support a variety of plants — annuals, perennials, succulents, tropical plants and even herbs and vegetables — and can be a complete green wall from day one. Plus, with soil in all the containers all the way up the side of a wall, planted walls provide more shading and insulation for the building.

Q: When did you start working on a planted wall system?

Well, we started getting questions about green walls almost as soon as we introduced LiveRoof in 2006. We began formal R&D efforts on planted walls in 2008 and put four years of system evaluation and prototype testing into LiveWall.

Q: Why did you decide to develop your own planted wall system?

Because we could not find an existing system that was simple to install and plant, easy to maintain and change, and good at growing plants. The biggest surprise in our tests of current systems is that even many easy-to-grow, resilient, disease-resistant plants (like Hostas, Sedums, Alliums) kept dying. No matter what we tried in terms of irrigation, pruning or fertilization, we could not keep plants healthy in the systems we tested.

So, just like in our development of LiveRoof, we set out to bring our horticultural expertise to bear to understand the problems and design a better system to solve them.

Q: Your WallTers look like window boxes.

That was the inspiration. The idea of window boxes as the model for wall planters came up in our discussions with other horticulturalists, including Ed Snodgrass [internationally renowned green roof and vegetative wall expert and consultant] and David Fell at Hawaiian Sunshine Nursery, our licensed regional grower and distributor in Hawaii.

The reason that window boxes work so well is that they provide proper orientation for roots and stems and allow for irrigation like rain. The engineering challenge was to design a vertical system that could scale up and make it practical to install and maintain an entire planted wall with perhaps hundreds of boxes. That included devising a set of components to make it a complete system.

Q: What does LiveWall cost?

Of course, I have to say that it depends. For a professionally installed system, the price range is about $90 to $125US per square foot (depending upon the size of the system, local labor rates, and the type of plants). That is all-inclusive: green wall planning and design, pre-installation consultation and technical assistance, all the system elements and components (including irrigation), all the plants, delivery, installation.

Q: How is LiveWall distributed and serviced in Canada?

Just as with LiveRoof, we have a national network of licensed regional growers. In Canada that includes LiveWall Ontario (Mt. Brydges, Ontario), Pépinière Premier Plant (Saint-Sulpice, Quebec), Eagle Lake Turf Farms Ltd. (Strathmore, Alberta), and N.A.T.S. Nursery Ltd. (Langley, British Columbia). They can customize plant selection for every LiveWall project. They can deliver the module inserts abundantly vegetated with locally cultivated plants that are full-grown and flourishing for instant results and lasting beauty.

#1TipTo Making Your Business Website10 Seconds More Attractive

Do you think that your website has the ‘sticking power’ necessary to keep visitors engaged?

According to Jacob Nielsen1, whom the New York Times called “the guru of Website usability” provides this summary: ‘Users often leave web pages in 10–20 seconds, however, pages with a clear value proposition can hold people’s attention for much longer’.

There are many factors that drive visitors away, and plenty of reasons why they linger on and return to a given page.  Let’s agree that the first 10 seconds of the page visit are critical for users’ decision to stay or leave. The question remains: what can and should you be doing with such limited time?

#1 Tip: Communicate your Value Proposition

What does Value Proposition mean? 
“Why should I buy this product, service or idea?” asks your customer. Your value proposition must answer this, in a compelling way. It’s a short statement that clearly communicates the benefits that your potential client gets by using your product, service or idea. It “boils down” all the complexity of your sales pitch into something that your prospect can easily grasp and remember.

Here’s an example of what a real estate firm may sound like: “We at Home Corp Real Estate help homeowners sell and buy property. We guarantee that your home will be sold in 30 days or less, or we’ll buy it ourselves.”


What do I do with it?
Think of your value proposition as the foundation of your online marketing plan. It will forever help you stay on course, as it serves as a reminder of what separates your brand from your competitors. Everything that you do online, from messaging, content, offers, ebooks, case studies, white papers, video should be delivered in a way that it supports your value proposition.

It’s not about you; it’s about your customer.
David Meerman Scott2, author of The New Rules of Marketing and PR defines it this way: “the most important thing to remember, is to put your products and services to the side for just a little while and focus your complete attention on the buyers of your products. You must put your entire focus on helping your customers succeed.”

Creating customer value, that’s the proposition.
Every page on your website is an opportunity to market your brand and the value you bring to the visitor. Think about what makes your business or service distinctive. Why is your offering preferable to other options for solving the need? Do you have something special that’s worthwhile to share? Is there some way to highlight how you’re distinct from others?

Keep these thoughts in mind as you develop your own unique value proposition:

1. Put yourself in your customers’ shoes to find the answers.
Who is your potential customer? What do they do and what do they need? What problems do they need solved? What does the customer value most?

2. Know your competitors.
Think again from your customer’s perspective and ask how your product or ideas create more value than your competition. What can you do with your idea, knowledge of your market to really improve their lives, health, financial situation, status, prestige, etc… over and above your competition.

3. Know how your product solves a need.
Identify what the rational and emotional benefits of solving the need are? How does the product, service or idea solve the problem or offer improvement? What value and results does it offer the customer?

4. Proof of concept.
How can you demonstrate that your approach has worked to solve similar problems for others? How do you substantiate your claims? How do they know that what you say will happen, will actually happen?

5. Uniqueness.

Why is your offering preferable to other options for solving the need? Do you have something special about you that are worthwhile to share? Is there some way to highlight how you’re distinct from others?

Producing winning results is greatly dependent on the inclusion of a solid, well-defined value proposition that’s incorporated into your business Inbound marketing plan.

Does your company have a UVP (unique value proposition)? If not, will you be developing one for your business. Let us know if you found this article helpful.

Bringing it Home – How TRCA’s Green Home Makeover is supporting green renovation and market transformation

By Shannon Logan, Toronto and Region Conservation

With energy costs on the rise, and summer water restrictions across many municipalities, homeowners are increasingly considering the energy and water efficiency of their home, and turning to their contractor or trade professional for advice. With almost half of the private dwellings in the Greater Toronto Area over 30 years old[1], and home renovation on the rise, the question is, how can we help make it truly green? There may be no shortage of emerging technology in energy and water management out there, however for some innovative products, consumer markets may not be strong enough to support competitive pricing. So with “green renovation” now a mainstream buzzword, and trend setters starting to adopt some of these, how can renovators and homeowners identify strategic renovations, estimate the return on investment, and understand ongoing maintenance considerations? Marketing transformation towards efficient products is already happening in areas such as low flow toilets, water efficient washers and natural gas furnaces. But for older homes with poor insulation, mid-efficiency appliances and fixtures, how can we accelerate this change?

Governments and utilities are struggling with the same issues. With aging energy and water infrastructure on a large scale, they want and need to encourage energy and water efficient in the homes they service. Toronto and Region Conservation (TRCA), one of 36 Conservation Authorities in southern Ontario, is working with these partners in strategic planning and education to homeowners and the building industry in support of sustainable resource use, achievement of conservation goals and a healthy environment.

Local demonstrations designed to educate homeowners and renovators are a key part of our collective effort. Earlier this year, TRCA, along with a number of key public and private partners, unveiled the Green Home Makeover, an innovative project designed to:

  • Showcase innovative eco-friendly home improvements and retrofits for single detached homes;
  • Educate homeowners and the building industry on new technology installation and maintenance;
  • Support monitoring and evaluation of innovative sustainable technologies; and
  • Provide an on-the-ground illustration of retrofit benefits and connect people with how-to information.

The Makeover is part of the County Court SNAP (Sustainable Neighbourhood Retrofit Action Plan) being developed by TRCA, Region of Peel, City of Brampton and the community (visit www.sustainableneighbourhoods.ca). This visionary and measurable Action Plan will transform the older neighbourhood to improve the local environment, prepare for climate change and make it a better place to live, work and play. Through local demonstrations like the Makeover, it connects on a personal level with property owners, encouraging behavior change and learning about what they can do at home to save water, energy and contribute to a greener community.

Located at 71 Turtlecreek Boulevard in Brampton’s 30 year old County Court suburban neighbourhood, the Green Home Makeover showcases sustainable indoor and outdoor renovations that will have big energy and water savings. Renovations includes a high-efficiency HVAC system, improved basement and attic insulation, weatherization, energy and water efficient appliances, drain water heat recovery, Energy Star windows and doors, ultra low flow toilets, rain barrels, a rain garden, permeable driveway and walkway and water efficient Fusion Landscaping®[2]. The Makeover was made possible through donations of product and time from Lead Platinum sponsor Reliance Home Comfort, Platinum sponsor Sears Canada, Gold Sponsor Green Saver and numerous Silver sponsors. Other partners include Enbridge Gas Distribution and Hydro One Brampton as well as green building, water and landscape industry associations.

As part of the integrated design process led by Sustainable Buildings Canada, the team confirmed the most appropriate features to include in the home and estimated potential future savings. This includes: a reduction in total energy and water consumption by 50%; an EnerGuide rating increase from 58 to 76; improved home comfort and indoor environment; reduced rainwater runoff and improved water quality; and an attractive outdoor landscape and improved biodiversity.

The Makeover is a resource for building industry professionals looking to learn more about green renovation. Product information sheets, which include costs and benefits and supplier contacts, are available on the project website, along with a series of short renovation videos. TRCA’s STEP (Sustainable Technologies Evaluation Program), part of the Living City Campus at Kortright Centre for Conservation in Vaughan, will be monitoring energy and water consumption and landscape LID (low impact development) performance over the next two years (visit www.sustainabletechnologies.ca and www.thelivingcitycampus.com). Tours of the home are also offered to interested groups and residents. Homeowners Paul and Marisa and their family are also a fantastic resource. They have seen the changes first hand, are taking a keen interest in sharing their experience with the community and industry, and after all, know their home best!

It’s not enough to simply create a demonstration project like this and hope it makes an impact. It has to be part of a larger program that makes it appealing for people to make change. This is why TRCA, in partnership with public and private sector partners, is leading a residential retrofit program for the whole neighbourhood. This one-window program, called the Green Home Discount Package, includes incentives and discounts on a series of strategic indoor and outdoor home renovations that homeowners are likely interested in given the age of this neighbourhood. The message and incentives have been custom designed for County Court, and have been informed by our local social marketing research. The pilot program was launched this summer and will continue through 2012 with local promotion, tracking, homeowner recognition and program evaluation.

Starting with a Tight Building Envelope to Reduce First Costs

By Monica Karamagi

For builders, building green and reducing energy consumption must always be tempered with bottom line costs.

Fortunately, what leads to reduced energy usage and lower monthly utility costs for property owners can also mean reduced costs for builders. This is achieved when the builder takes a system-wide approach to energy efficiency.

When builders use a system-wide approach, the cumulative life cycle operating costs are lowered. This is because the building’s monthly operating costs are lowered. In this scenario, high quality mechanicals, smart control strategies and efficient lighting strategies are all key pieces of the puzzle, but energy efficiency really starts with the building envelope.

When builders think of the building envelope, they tend to think in terms of R-value, construction types, aesthetics and more recently, the total U-value and continuous insulation.

There is another aspect that is being recognized in contributing to the building envelope – air tightness. According to the U.S. Department of Energy (DOE), uncontrolled air leakage in a typical building can account for as much as 30-50 percent of a building’s heating and cooling costs. The reason is simple: every bit of outside air that enters the building through air infiltration must then be heated, cooled and/or dehumidified to get back to a thermostat’s set point.

 

Spray polyurethane foam (spray foam or SPF) insulation helps builders achieve air tightness goals. It acts as an air barrier, vapor retarder, weather resistant barrier and continuous insulation. It is also helps builders reduce material costs and HVAC (heating, ventilation and air conditioning) tonnage. Spray foam can also help builders achieve LEED®  Canada(Leadership in Energy and Environmental Design) certification.

Material Costs

When a tight building envelope is achieved with spray foam insulation, builders often see reduced material costs across the board. Because closed cell SPF (typically used in Canada) provides an extremely high R-value (in the range of 15-16 cm), builders can meet R-value requirements using 2×4 stud members, as opposed to the 2x6s often required when insulation needs to be thicker to meet R-value requirements.

In addition to reducing lumber usage and costs, using 2×4 framing leads to savings on window and door extension jambs and provides additional square footage.

HVAC Reductions

Performance and design of mechanical systems must match the performance of the building envelope. With the energy reduction that tight buildings provide, HVAC systems can be significantly downsized, saving upfront costs. However, several other considerations must be made:

  • Ventilation rates and strategy as “fresh air” is no longer supplied through the gaps and cracks in the building
  • Use of sealed combustion or power-vented combustion equipment to prevent flue gas spillage and back-drafting
  • Detailed sizing analysis (e.g., Manual J) to achieve a right-sized HVAC system that does not short cycle and ensures comfort, and minimizes upfront and operating costs
  • Proper system design and equipment selection to ensure humidity control for comfort
  • Good duct design to ensure sufficient air mixing and distribution

LEED Certification

Commercial and high-end residential buildings are increasingly designed with LEED Canada certification in mind. LEED assigns points based on energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

Spray foam insulation provides valuable points in several areas in the pursuit of LEED certification:

  • High quality insulation
  • Air tightness. A typical commercial building has air leakage rates of 0.017 to 0.045 cubic meters per minute (cmm) per square meter (sm) at a pressure of 75 pascals. ASHRAE defines a tight building as one with leakage rates of 0.003 cmm/sm at 75 pascals.
  • Design flexibility to easily accommodate ducts in conditioned space

Spray foam can also contribute in less obvious ways. In the LEED Materials and Resources category, closed cell spray foam can assist in achieving points for material efficient framing. Closed cell spray foam increases the racking strength and facilitates use of wider structural member spacing.

When buildings are constructed with a system-wide approach, and given a tight building envelope, they can provide construction cost savings for the developer, as well as energy efficiency over the life of the building.
