About Coolearth Architecture Inc.

Coolearth brings sustainable architecture to life.


Whether it is Net-Zero, low-emissions design, LEED, Passive House, or just simple and smart sustainable solutions: we help clients from institutions to large corporations realize their building’s potential. 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 effi ciency, comfort, and durability. Our extensive experience in Ontario, from design to construction, means we understand the prime drivers in making a building sustainable, durable, and comfortable. 


Highlights of our Firm


Education and Teamwork

Our ability to manage 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. 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.


Research and Data-Driven Design

We conduct in-house research on sustainable materials and methods including energy modelling, thermal performance of assemblies, passive solar design,  and ground-source heating.


Strong Community Partner

We are engaged members of our community, within the public sector, non-profi t, 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. We are members of Passive House Institute Canada (CANPHI), Passive Buildings Canada, 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 offi ce 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 Offi ces 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.
