Salus Clementine is the first multi-unit residential Passive House project in Canada, and the first affordable housing project to achieve Passive House project in North America. By reaching the Passive House standard, the heating demand is reduced by up to 85%, compared to the current Ontario Building Code. Additionally, as Ottawa's most sustainable affordable housing, national greenhouse gas (GHG) emissions are reduced by 75% on heating only. Each apartment operates on a heating budget of $27 per year. This project consists of a four-storey, 42 unit structure, housing men and women who experience mental illness. Rehabilitation, community support, recreology, and housing are some of the services provided by Ottawa Salus Corporation.

The Salus Celementine project achieved LEED Platinum Certification and Passive House certification.

S + A Services Included:

Mechanical

Measures were taken to ensure that the target for space heating demand was less than 15 kWh/m2/yr and that the primary energy demand was less than 120kWh/m2/yr. Mechanical ventilation heat recovery is a pre-requisite of Passive House. During the design period, a commercial energy recovery ventilator (ERV) unit (with 2500 cubic feet/minute capacity) with Passive House certification was not available in North America. This made for a greater challenge in achieving the requested heating demand. The final design was also affected by thermal bridges, which occur where any mechanical system penetrates the building envelope.

Electrical

In order to achieve Passive House certification, which required primary energy demand of 120 kWh/m2/yr, energy efficient light fixtures with LED lamps were used throughout the building. The light fixtures in common and circulation areas are controlled by occupancy sensors to further reduce energy consumption. To satisfy the measurement and monitoring requirements of both LEED and Passive House, the energy consumption of major mechanical systems, the elevator and all the dwelling units are measured and recorded by a networked digital metering system. The recorded measurements can be accessed through a local area network (LAN) system or the internet.
