In W.G. Clark’s essay Replacement, he states that architecture "is the reconciliation of ourselves with the natural land." At LMSA, one aspect of this reconciliation involves sustainable design strategies. Some of these strategies can be simple and straightforward: we design buildings with operable windows to provide natural ventilation and we use natural daylight as much as possible in lieu of artificial light for indoor spaces. These tactics reduce our need for pollution-generating energy sources and provide a direct connection to the environment around us. The afternoon breeze and a passing cloud become a part of our daily experience. Other sustainable design strategies are unique to a particular project, growing out of our design process: the careful exploration of the possibilities and constraints of a site and our close collaboration with the stakeholders of a project.
