hEstablished in 2010, we help nonprofits, NGO’s and corporations discover ways to use design to create more energy-efficient healthy and resilient buildings.

We look at buildings differently.

We start by using our exclusive organizational change and development tools to determine your goals for the project. Included is not only the typical payback, ROI, or NPV but also a carbon risk management assessment.

You deserve more than a checklist.

Knowing the goals, we go right down into the design process with your design team. We know where and when to use state-of-the-art energy, daylight and hygrothermal modeling to ensure your building will be truly high-performance.

We are a privately-owned for-benefit corporation whose mission is to reduce and eliminate the greenhouse gas emissions from the built environment.

Our best work is done while working alongside architects and their teams acting as an impartial advisor. 

Exceptional indoor air quality and a longer-lasting building are the benefits of high performance.

Including in our mission is the social impact goal to reduce fossil fuel consumption from buildings to the point that it will enable the closure of coal-fired power plants which are often located in low-income neighbourhoods and cause respiratory issues. Closing coal-fired plants is critical in enabling Black and other minorities in having a safe and healthy living environment. We must shift off of fossil fuels quickly in order to limit warming to 1.5oC, or even 2.5oC, and in order to do so, we must transform our society to an equitable one.  

Companies like yours have been hiring us to create award-winning facilities like Humber River Hospital and the Fogo Island Inn. Hire us and discover the affectingchange difference.

Founder & CEO

Hi, I’m Sandra. I’m a sustainable design guru that has created many game-changing projects that have set precedents and have won, in total, over seventy-five awards.

When I was eleven, my life suddenly changed after an F4 tornado struck my town and my family went to help. It was like a war zone. I have been emotionally connected to weather disasters ever since and it explains why I am so passionate about mitigating the effects of climate change.

My architectural design thesis at Ryerson University was, “Exogenesis: a manned mission to Mars” and that was back in 1994… I am a futurist but I have since decided that we should focus on fixing things here on Earth. As an optimist, I believe that we can enable our society to lessen the impacts of climate change by significantly changing how we manage our built environment. 

Decades of design experience, my qualifications as a registered Designer for interior spaces and small buildings (ARIDO IDC) and a Masters Certificate in Organization Development (MCOD) enable me to help my clients to use design as a tool to reach their high-performance potential. 

I am also LEED-Accredited Professional with a Specialty in Building Design + Construction (LEED AP BD+C) and I taught the LEED-accreditation prep course for HOK Architects. But there is more to sustainability than LEED, so I became a Certified Sustainable Building Advisor (CSBA) and taught the Certified Sustainable Building Advisor course for the Canada Green Building Council.

In my spare time I advocate for climate change solutions. I was a volunteer Community Engagement Leader for Project Neutral. I have been trained by Al Gore as a Climate Reality Leader and I am available for speaking engagements upon request.

Our CEO, Sandra Leigh Lester, has worked with, been seen on, or has spoken at the following conferences:
