Cement Sustainability Initiative [CSI] Global effort will be felt at home by Jim Taggart, FRAIC, sabmag editor The Cement Sustainability Initiative [CSI] is a global effort by 25 major cement producers with operations in more than 100 countries who believe there is a strong business case for the pursuit of sustainable development. They have come together under the auspices of the World Business Council for Sustainable Development, and met this fall in Richmond, BC. Initiatives launched by CSI include strategies to reduce the GHG emissions associated with the production of cement, and the development of products with enhanced environmental performance. Among those mentioned at the post-conference media briefing were: Contempra Introduced in Canada in 2011 and referenced in the National Building Code under the name of Portland-limestone cement, the new Contempra cement reduces CO2 emissions by 10%, while producing concrete with an equivalent level of strength and durability to concrete produced with regular Portland cement. This is done by intergrinding regular clinker [the main ingredient in cement] with up to 15% limestone, which is 10% more than in regular Portland cement. Reducing the clinker content of cement in this way reduces the amount of emissions associated 8:21 AM with its manufacturing. Although cement typically makes up only 11% of concrete by weight, it is responsible for 80% of the GHG emissions associated with the production of concrete. Photo-catalytic Cement Still in the experimental stages in North America, these new

cements can reduce urban smog by containing materials that act as a catalyst to bind airborne nitrogen and sulphur oxides into insoluble salts. These harmless salts are then washed away by rain or during general maintenance. The result is that buildings stay cleaner for longer. This process requires sunlight, so will only be effective on surfaces regularly exposed to the sun. However, if this same product is used for paving highways or incorporated into unit pavers in urban areas, it could have a beneficial impact on air quality by absorbing automobile exhaust fumes close to the source. The Ontario Ministry of Transportation is conducting a pilot project with a section of noise barrier on Highway 401, and will compare results against test benchmarks achieved in other countries. Pervious Concrete Pervious concrete pavement and Permeable Interlocking Concrete Pavement reduce stormwater run-off in urban communities by allowing water to seep through the pavement to recharge natural groundwater levels, thereby providing an alternative system for recharging groundwater that might otherwise require swales and retention ponds.

Mark Lucuik, P.Eng., Principal, Director of Sustainability, Morrison Hershfield Mark has worked on over one hundred green buildings in Canada and the US, and has sat on several CaGBC committees. He was also a CaGBC Board of Directors Member, a founding Board member of the CaGBC Ottawa Chapter, and sits on the Board of the Athena Institute. Jack [Robert] Meredith, P.Eng., President, Healthy Green A pioneer of energy management and direct digital control [DDC], Jack believes strongly in outreach and education for the younger generations of professionals. He helped to found the ASHRAE chapter on Vancouver Island, and is former chair of the CaGBC Education Committee and CaGBC Technical and Program task forces. Martin Roy, P.Eng., President, Martin Roy et AssociĂŠs Martin has been a member of the CaGBC from the start and has played a significant role in the development of CaGBC's LEED products. Since 2005, he has worked on CaGBC's Technical Advisory Group helping to adapt the LEED-NC rating system to Canadian conditions. As a lecturer, he inspires students, design professionals, and the public alike.
BIPV installed in green building prototype in Mississauga
Eclipsall, a Canadian manufacturer of high-performance PV modules as well as BuildingIntegrated PV [BIPV], has completed its first BIPV installation in Mississauga consisting of a custom-designed BIPV canopy and BIPV tower. BIPV materials are designed to replace conventional construction materials within the outer envelope of a building including roof, skylights, glazing and facades. The project in Mississauga uses 30 custommade frameless glass-on-glass PV modules installed and used as a street-level canopy along the south facade of the building. Also, there are seven glass-onglass modules incorporated into the curtain wall tower on top of the building structure. Info: sylvie@eclipsall.com

Micropro Sienna has no solvents, simulates cedar look MicroPro® Sienna is pressure treated using a patented wood preservative process that uses micronized copper to provide durability to wood used in exterior applications. Because solid copper is injected into the wood at a microscopic level, without the use of solvents, less is released into the environment. The cedar-like colour is achieved by a similar process that injects iron oxide pigments into the wood. It has been awarded GREENGUARD Children and Schools Certification for use in sensitive environments based on its low VOC emissions. Info: www.microprosienna.com

Minimal use of materials The premise for the construction of this building was the minimal use of materials [polished concrete, no acoustic tiles or gypsum on the columns, exposed concrete on walls]. Eighty-seven ecological materials were catalogued using ATHENA software that enables designers and builders to assess and compare their environmental impacts. To minimize the impact of environmental pollutants on the health of the occupants, all paint, adhesives, sealants, composite wood and carpets used had a low to zero rate of volatile organic compounds and contained no urea formaldehyde.

The architectural walkway and staircase in the atrium were created with driftwood, retrieved from Lake Huron’s Georgian Bay. Experimental products were also used, such as glass powder as an additive to cement, and kitchen counters made of 93% recycled glass. By proposing a Platinum LEED-certified environmental construction project in the downtown case, the promoters of the Maison du développement durable made a very strong statement concerning respect for the built environment. Conceived and constructed to serve as an educational tool, the success of the MDD will ultimately be measured both quantitatively - in the performance of its environmental systems, and qualitatively - in the response of its occupants and in the influence it exerts on others through its educational components and outreach programs. To date these have included 150 guided visits of the building, a dozen conference presentations and more than 1,000 media appearances in five countries. For the casual visitor the MDD also offers self-guided tours [by way of touch screens that monitor and explain real time building performance], and a library of more than 100 environmentally-friendly materials.

A two-storey high ceiling clearance gives a sense of volume to part of the interior [5]. Reflective ceilings and large areas of triple glazing make a bright, open interior [6]. Detail of engineered wood roof support framing [7].
The integrity of the river valley ecosystem is protected by the implementation of low-impact operational processes as part of the Regional Corridor Plan, and long-term, integrated resource planning with the nearby municipality. Interior green spaces are integrated with the exterior through strategically placed glazing creating a continuity and connection to the surrounding environment. In planning the location of the building, consideration of orientation to the sun and prevailing winds was balanced against maximizing opportunities for views. The building is low to the south-west and emerges from the ground, with expansive triple glazing that allows penetration of soft northern light and provides views of the lake and dam that supply all the building’s required energy. Tempered air Glazing assemblies provide day lighting and natural ventilation with operable windows. 100% outside fresh air is tempered by two strategies; the south-facing SolarWall system and geothermal ground tubes, which are controlled by a digital monitoring system. The building’s air intake draws fresh air through the ground tubes in shoulder seasons and summer tempering the air to provide free cooling. Air drawn through a solar air wall provides free warming air in the shoulder seasons and winter. The synchronization of the two air supplies in an alternating fashion significantly decrease costs for conventional energy input heating and cooling. Interior green roofs above the meeting room complex purify the air through natural air currents and strategically placed ventilation to direct air flow. All mechanical and electrical systems are set on sensors to respond to fluctuating occupant loads.

Subsurface water flows into a weeping tile system around the building’s footings and is directed to a collection cistern. This water source is used for all non-potable water requirements in the building. Surface water run-off and site storm water is directed into bioswales. These eventually lead into a retention pond that serves as a natural water cleaning system preventing contaminated water from entering the watershed. The pond is constantly replenished with overflow diverted from the cistern. The pond has developed quite well as a system and is now inhabited by a variety of amphibians in a marsh environment. The pond also provides educational program opportunities. A Waterloo Biofilter system has been installed to treat waste and reduce water for sewage conveyance. A variable refrigerant flow system and energy recovery ventilator allow for efficient and cost effective operation of the mechanical systems with precise controls based on fluctuations in occupancy. The selection of materials was based on what was available locally, manufactured sustainably and would have low or no VOC

characteristics. These materials include concrete, stone, glass, and engineered wood products. The team made sustainable design a priority from project inception to completion. The integrated design process with the sustainability consultant ensured the design team worked collectively in implementing the project design principals. The finished building is more than a functional administrative building. It serves as an expression of what can be achieved by committing to sustainable measures and will act as an educational resource to support a mandate for environmental stewardship of the organization, and resource to the community. Currently tracking LEED Platinum, the building is truly a living, thinking, breathing, entity. ď ´ MACKENZIE HOWSON, ANNA WEX AND RANDY WILSON, PRINCIPAL , RANDY WILSON ARCHITECT INC.

HVAC Design has Changed Forever
ANNOUNCING THE WORLD’S FIRST WATER-SOURCE, MODULAR 575V VRF SYSTEM Whether for new buildings or for retrofits, our new watersource, 2-pipe VRF system uses less materials than 4-pipe systems and has a significantly lower maintenance cost. Best of all, it’s 575V, so no transformer is needed. And because it’s modular and installed indoors, there is no need for cranes or heavy equipment. In fact, our new 575V VRF system is so compact it is easier to incorporate into any design, plus it is less expensive to install and maintain.
Mitsubishi Electric’s new water-source, 575V VRF system is a game changer.

The City of Edmonton set the bar high by issuing an international Request for Proposals for the redevelopment of the downtown Edmonton Municipal Airport, now known as the Blatchford Redevelopment, to house 30,000 people in a carbon-neutral, mixed-use development that would be a leading model of sustainability. By Blair McCarry
Expected to be developed and built over the next 20-35 years, the Blatchford project totals 2 million m2 of new development that reaches an urban density of 5.0 FAR. It consists of the following three neighbourhoods: • The Agrihoods District on the west side combines low- to mid-rise residential with intensive urban agriculture opportunities. • The Technology and Research District on the east side introduces largely mid-rise housing and the expansion of the Northern Alberta Institute of Technology [NAIT] to take advantage of the new light rail transit running through the centre of this community.

• The Town Centre District, located immediately south of the other two districts is a higher density zone integrating
major office, commercial, and retail businesses with urban-style housing.

URBAN DESIGN ISSUES HIGH WALKABILITY/TRANSIT-ORIENTED DESIGN: The urban design focuses on providing a walkable community with significantly reduced private vehicle use. The new light rail transit [LRT] station is under construction at the south end of the development and will be extended through the development to the north. A tram system is proposed to provide transportation locally within the development. Residents and visitors will use a ‘park once’ parking approach in the underground parking facilities and will be encouraged to walk and use site transit to get around. SUPERIOR ACCESS TO OPEN SPACE:
and heating for the development would have to be generated on site for net-zero carbon emissions on an annual basis. A review and evaluation of the potential solar, wind, waste and geothermal energy sources for the Blatchford development was carried out. In brief, an evaluation of renewable technologies revealed that solar power generation would require more than the site area and that the site was not a good wind location, even if you could install large generators. The City’s Clover Bar waste facility, which is upgrading to make use of the majority of the urban waste by gasification to produce ethanol so it was not an appropriate source for generating electricity. The final proposed energy sources - biomass and deep geothermal - were selected to produce electricity with thermal processes, as well as heat for district heating with biomass being the largest contributor.
A large urban park is planned with lakes excavated to provide an exceptional local and regional amenity. The excavated earth from

INTERVIEW WITH: MiriamTurner AVP Co-innovation at Interface, Inc. heads the carpet tile manufacturer’s Net-Works™ program, which is as much a development program as it is a novel recycling program. visit: www.interfaceglobal.com/Products/NetWorks.aspx for more information about the net-works program.
âSABMag: What is it doing for the local people? áMT: Participating villages in the Danajon Bank are collecting an average of 200 kg of nets per village each month. For every 2.5 kilos of nets collected, a family can purchase one kilo of rice – approximately 4,800 extra meals per village annually on the tables of poor families, whose typical monthly household income is less than $195. Net-Works has also established Community Banking systems for the residents—supporting and strengthening the local, developing economy, and providing new financial opportunities for residents. Members have already taken out loans for educational needs, and tapped funds to start new forms of

LIFE CYCLE ASSESSMENT (LCA) OF PRECAST CONCRETE The Canadian Precast/Prestressed Concrete Institute (CPCI) has been hard at work to place the most up to date information about the industry in the hands of design professionals. Working with the Athena Sustainable Materials Institute, a Life Cycle Assessment (LCA) study has been conducted to evaluate the environmental footprint and cradle-to-cradle impacts of precast concrete, which is compliant to the ISO 14040:2006 Standard for Life Cycle Assessment.
USING THE LCA The LCA material data collected in the study is already being put to good use through the CPCI Sustainable Plant Program. This unique program aims to decrease the impacts the precast industry has on the environment in the areas of global warming, energy and water consumption, waste, dust and noise through benchmarking and goal setting. In addition, CPCI will continue this leading edge look at the industry by producing an Environmental Product Declaration (EPD) for precast concrete to the ISO/TR 14025:200 standard.
