Environmental Building Design
There are many ways in which efficient building design can lead to efficient energy use. Such measures are taken both in the architectural design of the building itself, as well as in the various infrastructure and services that are installed in it. These include: proper building to site orientation, high efficiency lighting, optimized daylighting, oversized low restriction ducts, variable speed drives in the HVAC units, increased building insulation, heat mirror glass, reflective roof coating, occupant sensors throughout the building, and efficient office equipment.
