The Firm


Coolearth Architecture inc. provides environmentally sound architectural solutions. Our services include site selection, project definition, design, contract/permit documents, contract administration, tendering and consultant selection. We offer comprehensive architectural services including the design of new net-zero or low carbon structures, major renovations, energy models and analysis.

Coolearth Architecture inc. was founded in 2008, to design, supervise and implement projects that achieve high levels of energy efficiency, comfort, and durability. Our extensive residential experience in Ontario, from design to construction, means we understand the prime drivers in making a building sustainable, durable, and comfortable.

Please take a look at our portfolio to see our projects.



Coolearth Architecture Inc. is committed to collaborative design. We believe that environmental sustainability begins with an integrated partnership of client and design team at an early stage in the design process. This collaborative approach is the most effective way to identify sustainable goals and opportunities at all stages of the design.

Our ability to manage and collaborate with complex teams is demonstrated on projects we conducted for TRCA where we evaluated over 20 historic buildings, including energy upgrades, repairs, and accessibility; and on the Coniston Affordable Housing project.

The firm utilizes Building Information Modeling (BIM) software for all our projects, benefiting from its superior visualization and interference checking as well as the capability of analysis of design and energy models, while maintaining the ability to communicate with others in AutoCAD format.  We also offer unparralleled custom energy modelling solutions and visualizations to help ensure our building perform as expected.

Strong Community Partner


We are engaged members of our community, within the public sector, non-profit, and community groups (Toronto Region and Conservation Area, Nourish and Develop Foundation, Shawanaga First Nations, and more). Last winter we organized The Passive Building Show; and hosted free public seminars on net-zero design for the public as part of Green Energy Doors Open 2015 and 2016. We have hosted a local photographer for three years as part of the Contact Photography Festival and a local designer for the last four years as part of the Toronto Offsite Design Festival.

We are members of Passive House Canada, the Canadian Green Building Council, and the Net-zero Coalition. We also participate in the 2030 Challenge and the AIA’s 2030 Commitment which encourages modelling energy performance over prescriptive design and requires an office commitment to greening internal operations, and focusing staff resources on green design.

Lead by Example

Our Principal, Sheena Sharp has taught courses to the Ontario Association of Architects on the 2030 challenge, net-zero design, and transitioning to the low carbon economy. She sits on the 0AA Sustainable Built Environment Committee (since 2008), is the head of the OAA Building committee (since 2011) — which is making the OAA Offices Net-Zero through an envelope retrograde — and is on the Advisory Board for Toronto’s 2030 District. Sheena is also a member of the Provincial Government’s Climate Action Group.

Coolearth Architecture is committed to ongoing education for our staff, including Passive House training, net-zero seminars and lectures, and natural building conferences. We are always trying to learn and improve the services we offer through dialogue and outreach. All of our projects are built on a foundation of collaboration and strong inter-personal relationships.
