Ken Soble Tower Renewal

PDF - Report

This Case Study features the Ken Soble Tower, CityHousing Hamilton’s oldest residential social high-rise.

In recent years, deterioration had left the tower almost uninhabitable. With more than 6,000 households on their waitlist, the city was also facing a critical shortage of affordable housing.

CityHousing Hamilton committed to addressing both challenges by reinvesting in critical capital repair to:

  • restore the building
  • provide key modernizations
  • convert the residency profile to seniors

Project goals

CityHousing Hamilton looked at several options to renew the tower. These ranged from making capital repairs to selling the landmark building.

After extensive consultation, CityHousing Hamilton chose a top to bottom building renewal. Their main goals were to:

  • return the building to habitability by modernizing with select upgrades to energy, accessibility, life safety, and social amenities
  • create net-zero-ready housing through Passive House EnerPHit Certification
  • address capital repair backlog
  • maintaining affordability
  • create 146 affordable homes for vulnerable seniors

Project overview

Built in 1967, the tower has long been in serious decline. Problems ranged from lack of ventilation to building envelope issues and outdated systems. In 2017, the tower sat 70% vacant and had a large capital deficit.

Instead of demolishing the tower, CityHousing Hamilton has seized the opportunity to turn it into one of Ontario’s most cutting-edge tower renewals. A Passive House design strategy was adopted to:

  • improve tenant comfort
  • increase energy efficiency performance
  • reduce operating costs

Ken Soble Tower is striving to be North America’s largest EnerPHit project, supported by Passive House International. EnerPHit is the Passive House retrofit standard.

The Passive House approach focuses on design strategies that increase:

  • climate resilience
  • indoor air quality
  • thermal comfort

It also reduces building operating costs and targets greenhouse gas reductions.

To support the project, the federal government invested $17 million in the retrofit. This included:

The project will feature a variety of energy-efficient construction techniques and technologies, consider tenant well-being and include key innovations.
