Selected Projects

Net-Zero Energy 50-unit Seniors Affordable Housing, Sudbury

This project is a 55,000 square foot, 5-storey, 51 unit building located just outside the City of Sudbury, in Coniston. It is adjacent to a recreational trail, and 2 blocks from a shopping centre and bus route which connects the community to downtown Sudbury. The clients are a non-profit seniors housing corporation who want to create a beautiful, energy efficient, net-zero energy, and functional building, that is also accessible, and designed for aging-in-place.

It incorporates principles of Passive House design such as super-insulation, air-tightness, triple-pane windows, and efficient mechanical system. We also incorporate principles of resilient design, passive survivability, and long-term operations planning. The integration of these sustainable features will cost more during the construction phase, but will pay for themselves through reduced monthly energy costs, as well as every day, because the occupants are comfortable and safe.

Breezeway Passive House, Toronto

This 3300-sqft multi-generational house in Richmond Hill is designed to be durable, energy efficient, comfortable, bright, and regenerative. The house is a bungalow with easy access to the house and yards via ramps, making it possible for residents of all ages to use the building with ease and elegance. Because it is a Passive House we will be able to achieve Net Zero energy with only 13 Photovoltaic Panels (PV) on the roof. We are looking at incorporating a Tesla Powerwall as a backup energy storage in case of power outages. The clients are a family who wants a space which is high performance and has a strong connection with the environment and nature. They want their home to integrate with the site, and promote biodiversity and abundance. Because of this we are incorporating Permaculture design principles throughout.

High Performance House, Parry Sound

This project is a 2200 sqft permanent residence for a couple looking to move to their dream property on a lake near Parry Sound, Ontario. We worked with them to identify their needs and designed the house to suite their vision. They were inspired by Frank Lloyd Wright’s designs and we incorporated this throughout the projects, including with natural cladding and colours, strong horizontal lines, variation in ceiling height, and more.

The principles of Passive House were used throughout to minimize thermal bridges and create a very air tight yet well-ventilated envelope. The combination of this elements provides a whole-house solution in a very comfortable house.
