Last week, ERA’s Graeme Stewart and Ya’el Santopinto joined City Housing Hamilton CEO Tom Hunter to present on the Ken Soble Tower Transformation at Passive House Canada’s National Conference in Vancouver.
The Ken Soble Tower Transformation project kicks off a groundbreaking program by CityHousing Hamilton to use the ultra-low energy Passive House standard for the retrofit of their existing buildings and as the standard for their new construction. ERA is thrilled to be working with CityHousing Hamilton realize this vision. Built in 1967 as modern affordable housing, the building’s rehabilitation will preserve 146 units of affordable seniors’ housing and ensure that state–of–the–art affordable housing is at the heart of the Hamilton’s growing West Harbour neighbourhood.
The project is poised to be the first Passive House high-rise retrofit in North America and it will demonstrate the tremendous potential for aging affordable housing in Canada to be modernized through Tower Renewal.
What is Passive House?
Common in Europe, the Passive House approach is centred around high-performance building envelopes, achieving nearly twice the insulation value of building code requirements, which drastically reduces required heating and cooling loads.
The Ken Soble Tower Transformation will:
- Reduce greenhouse gas emissions by 90%
- Reduce energy intensity by 70%
- Reduce resource consumption through a 45% reduction in utility costs
- Improve indoor air quality for resident health and comfort
- Extend the life of the building and its systems for another generation
The 2018 Passive House Canada Conference in Vancouver opens up this discussion to a broad audience of builders, contractors, architects, city-builders, and policy-makers, and ERA is proud to be part of the growth of this approach in Canada, sharing best practices with our colleagues and collaborators. A highlight of the conference included a tour of Dockside Green, a master planned community with affordable housing, district energy, and low carbon buildings.
