In the architecture profession's ongoing quest for sustainability, it is often the most fundamental practices that require rethinking. <em>Thermally Active Surfaces in Architecture</em>, the groundbreaking new study by 2009 Rome Prize-winning architect Kiel Moe, argues that water, with its higher density, is far better at capturing and channeling energy than air. By separating the heating and cooling of a building from its ventilation, the building's structure itself becomes the primary thermal system. This transformation of energy and building practices triggers a cascading set of possibilities for a building's health, structure, and durability. The first and only book of its kind, <em>Thermally Active Surfaces in Architecture</em> details ten contemporary case studies, from some of today's most innovative architects.
