The Sustainable Technologies Evaluation Program »

Working towards a more sustainable future by facilitating adoption of green technologies through monitoring, research, and knowledge sharing.

Low Impact Development »

The low impact development approach to water management focuses on preserving or re-establishing a site's pre-development water balance.  It includes practices like green roofs, bioretention areas, grassed swales and permeable pavements.

Solar Technologies Research »

STEP is involved in the monitoring and evaluation of a range of technologies that harness the sun's renewable energy, including photovoltaics, solar water heating, and solar air heating systems.

Permeable Pavements »

The use of permeable pavement in parking lots, driveways and roads allows rainwater to slowly infiltrate into the ground, resulting in less surface runoff, and greater protection of downstream aquatic habitat, property and swimming areas.

The Living City Campus at Kortright »

The Living City Campus is a centre of excellence for urban sustainability, where people gather to learn, research, demonstrate, and get inspired by technologies and practices that help build sustainable city regions.

Bioretention Areas »

Bioretention areas, also known as rain gardens, are shallow depressions in landscaped areas that are designed to receive and treat stormwater runoff from paved areas by using the natural properties of soil and vegetation to remove contaminants.  

Sustainable Heating & Cooling Technologies »

Heat pumps are among the most energy efficient technologies available for conditioning indoor air and generating hot water. STEP has evaluated two types of heat pumps - air source and ground source - installed at the Archetype Sustainable House.

  • Practicing effective erosion and sediment control during construction projects is essential to preserving the health of our terrestrial and aquatic habitats. Current approaches focus on preventing erosion, creating multiple barriers to the sediment release from the site, and applying promising new technologies like polymers.

  • The health of soil, vegetation and the lakes and rivers they drain into are intrinsically linked. Recognizing these connections during urban planning and development processes is key to creating functional landscaped areas. STEP carries out research and develops guidance on best practices for maintaining healthy soils.
