Green Design

Climate change affects all of us. Good design creates functional and comfortable spaces while leaving a smaller environmental footprint. We are fortunate to work predominately in the BC Lower Mainland for us to take advantages of City of Vancouver building bylaws and provincial BC Building Codes, among the most progressive in North America. We synthesize our core values of ecological responsivities with energy efficiency strategies in our design, utilizing our extensive knowledge of the latest building technologies such as superior insulation and energy-efficient lighting to reduce energy consumption while maintaining maximum liabilities.

We are proud that our staff are accredited with LEED AP© status. Leadership in Energy and Environmental Design certification allows us to comprehensively considers the environmental impact and the quality of the interior environment from site planning, material toxicity, to energy efficiency. We have always kept track of the latest building standards such as WELL v.2, whose rating system asks designers to focus on the impact of a built environment on human health and wellness. Elements such as daylight exposure, airflow, air quality, thermal comfort, and acoustical comfort are all integral components to create a safe, happy and healthy space.
