Ottawa, Ontario

Linda Chapman Architect & Christopher Simmonds Architect

The Mountain Equipment Co-op in Ottawa is a 2,150 m² retail store strategically located to encourage use of public transportation.  Stormwater is collected in a cistern.  Light coloured crushed stone roofing ballast enhances infiltration in addition to reducing the urban heat island effect.  Existing trees and new native plantings are used to shade the building and paved surfaces.

The retail facility was designed to consume only 50 % of the energy as specified by the Model National Energy Code (MNECB). The building envelope is airtight and has insulation values 4 times the MNECB required levels.  The lighting load is less than 50% of the MNECB due to the use of daylighting strategies and occupancy sensors.  Pending public approval, 10 % of the electrical energy usage is to be supplied by a wind turbine.

Water consumption 30% below the MNECB is achieved with high efficiency fixtures and appliances, waterless urinals, sensor activated faucets, and low-flow toilets.

The design minimizes the need for interior finishes. Finishes needed were selected on the basis of simplicity, low maintenance, minimal environmental impact, high durability and low VOC emissions. Salvaged douglas fir, sealed plywood, recycled gypsum board, VOC free adhesives and EcoLogo paints are some of the materials selected which are more environmentally responsible and contribute to healthier indoor environmental quality.
