EXECUTIVE SUMMARY In a city beset by a dearth of housing affordability, sustainability, and choice, this project set out to provide an alternative. Four compact, efficient units in a range of sizes, close to an intensely urban mixeduse corridor, are designed to capture a demographic range from young singles to young families to multigenerational households. The constraints of the tight site are offset by a complex unit configuration, offering each unit light and air from multiple sides, and impressive views to the North Shore. The project is a sustainability leader with triple-glazed windows and skylights, rainwater capture in underground cisterns for toilet flushing and irrigation, extensive provision of daylight and cross ventilation, a highly insulated, airtight envelope, and access to transit and a major bike route within a block. Replacing a deteriorating single family house with the maximum allowable density, the project contributes to the neighbourhood regeneration evident just down the block as a historic theatre undergoes revitalization. Designed to LEED Platinum, with a Walkscore of 95 and an Energuide rating of 85, this project sets an example for creative sustainability for local professionals and the public.

MAIN PROJECT DESCRIPTION Georgia Green ECO4Plex High Density Multi-Family Housing Zoning : RM4 Permitted FSR 0.75 | Increased FSR 1.02 Total Floor Area : 530.60m2 Total Site Area : 519.6m2 Building Height : 10.7m Date of Completion : November 2010


STRATEGIC DECISIONS Maximizing the density on a site with a small singlefamily house to transform it into a four unit building, housing 13 people, was the key strategic decision, underwriting a viable pro forma in a neighbourhood where investment in quality, sustainable housing could still be met with skepticism. With highly energy and water efficient housing as a baseline, the architect / developer sought to create a unique housing type. A complex, intertwined, configuration provides each unit access to light and air from at least 3 sides, supporting passive ventilation and lighting strategies while maximizing desirable views to the North Shore. Giving equal attention to the building’s exterior interaction with the site and the streetscape, the project contributes to neighbourhood regeneration, while demonstrating to visitors the potential for new housing types in a market flooded with homogenous products.

COMMUNITY Though each unit entrance is designed to create a sense of individual ownership, and rated party walls offer acoustic privacy, the unit configuration promotes informal interaction on and around the site. With a mix of unit sizes and types, compact, efficient, sustainable housing becomes available to a broad demographic mix, catering to the surrounding Commercial Drive neighbourhood. Sited half a block from a major commercial corridor well-served by transit, the project easily supports a car-free lifestyle. Two indoor and two outdoor parking spaces accommodate a low car ownership ratio, and covered, secure bike parking provides easy access to one of the busiest bike routes in the city, just a block away.

SITE ECOLOGY Situated in a dense, urban context, addressing site ecology focused on reintroducing natural ecosystems to the extent possible within the limited available area, rather than preserving existing systems. Permeable materials were used to the greatest extent possible, though permeable paving was deemed by the building department to be a tripping hazard on emergency access routes. The landscaping is designed around native, drought tolerant plants, and a rain garden serves to slowly infiltrate stormwater that is not captured by the rainwater cisterns.


LIGHT AND AIR With 97% of the occupied floor area within 7m of an operable window, the floor plans are organized such that all living spaces are situated on the perimeter with access to natural light and cross ventilation. In addition, five skylights with angled light wells bring daylight deep into the plan in three of the four units; a middle unit without access to the top floor still benefits from generous top lighting. An advanced lighting package includes energy star fixtures and lamps throughout, and airtight pot lights to prevent air leakage into unconditioned space.

40% reduction in water consumption

WATER CONSERVATION A combination of high efficiency fixtures and toilet flushing with rainwater results in water consumption of approximately 617 L/m2/occupant/annum compared to a baseline of 1026 L/m2/occupant/ annum, representing a 40% improvement in potable water consumption from the municipal water supply. Installing underground rainwater cisterns for toilet flushing and irrigation was a major challenge for the project. This strategy had not yet been included in the Vancouver Building Bylaw (VBBL), and therefore required an alternative solution, a time-consuming process that would be a deterrent to many project teams. Having demonstrated that the rainwater system would meet all of the functional requirements of the VBBL, the alternative solution was approved under the condition that all non-potable water was piped through a separate, parallel system and that all piping and outlets were labeled non-potable.

ENERGY PRESENT AND FUTURE The investors’ requirement for highly marketable North Shore views, the limitations of a narrow urban north-south site, and a commitment to energy efficiency were balanced to achieve high-performing, desirable units on a constrained site. With building orientation options limited, envelope efficiency was the first priority, creating the conditions to right-size and maximize the utility of high-efficiency systems. Triple-glazed, low-e windows and skylights, highperformance eco-batt insulation, and a design airtightness of 0.75 contribute to a robust envelope. With high-efficiency gas-fired hot water boilers, heat recovery ventilation, and a solar hot water installation to provide domestic hot water, the projected annual energy use is 14,695 kWh for an Energuide rating of 85.

MATERIALS AND RESOURCES With over 90% hard flooring, shoe removal cabinets at each entryway, and extensive natural ventilation, there is very little opportunity for harmful irritants to be trapped in the interior. Low-VOC paint and millwork also contribute to occupant health and comfort. All four internal stairways are defined by their substantial timber treads sourced from Vancouver Island, adding warmth to the otherwise austere, white interiors, and providing carbon sequestration. Local timber is also used for all framing, and the Silva Panel cladding at entryways, soffits, and the ground level on the North and South elevations.





LIFE CYCLE CONSIDERATIONS While much housing in Vancouver is built for a short market cycle of 30 years or less, this project was designed with robust, durable materials for at least a 50-year service life. With appropriate maintenance, it could last far longer, approaching European expectations for building life span. Purposedesigned as housing, the units are not particularly flexible within themselves; however, the unit mix provides flexibility on site, including the potential to accommodate multi-generational households. With the multiple-dwelling density maximized, even intense market pressures are unlikely to spur redevelopment; however, if the building were deconstructed, all of the timber framing, steel, aluminum, and eco-batt insulation could be easily reused or recycled.


EDUCATION AND INFORMATION SHARING Given the notable challenges in designing and building this very dense, highly efficient, unique to Vancouver project, a concerted effort has been made to disseminate lessons to both the professional community and the public. In a 2011 presentation to the RAIC, the design, permitting, and building timeline for this project were evaluated against the evolving green building policies in Vancouver, highlighting the areas where policy lagged behind practice, creating substantial hurdles. Acknowledging that occupant behaviour must reinforce energy efficient design, the strata frequently discusses their energy bills and energy conserving rules to insert into the strata bylaws. The project is included in ‘Exploring Vancouver: The Architectural Guide,’ by Harold Kalman and Robin Ward, gaining the attention of many urban explorers.
