Sustainable Design
Sustainable design must begin at the initial stages of a project and be carried through, ultimately to the maintenance of the facility. From the initial need for new program space, to site selection and concept design; we offer high performance building design; and deep green, low carbon and low resource consumption solutions for the built environment, including:
- Energy auditing
- Energy modeling
- Building envelop analysis
- Local climate adaptive design
- Passive design
- Geothermal heating and cooling
- Radiant heating and cooling
- Energy recovery
- Combined heat and power
- Renewable energy
