This monograph explores how architecture is influenced by and is responding to the global energy dilemma. Emphasis is placed on conservation techniques (using heavy insulation) and on passive solar construction (supplying most of a building's heating, cooling, and lighting requirements by sunlight). The basic problem is that architecture, like transportation, manufacturing, and agriculture, is heavily dependent on fossil fuels. It is estimated that approximately one-quarter of the world's energy supplies (two-thirds of which is derived directly or indirectly from oil and natural gas) is used for heating, cooling, and lighting buildings. Until recently, buildings in many countries were constructed with little or no concern for their energy efficiency or lifetime fuel costs. Building designers and researchers have recently become much more energy-conscious, due in large part to realization that paying for electricity is now the biggest expense in operating most large buildings. Also, the level of general awareness regarding energy use in buildings has risen rapidly as consumers, builders, real estate agents, and others have been exposed to education about climate conscious buildings. The conclusion is that the potential of energy-conscious improvements such as passive solar techniques and conservation for reducing dependence on expensive fossil fuel energy will be realized if designers, consumers, and regulatory agencies make an immediate and total commitment to make the transition to climate conscious buildings. Ways in which this transition can be accelerated include labeling of the fuel requirements of buildings by trade associations and local governments, provision of tax breaks for solar and other energy efficient homes, and establishment of energy standards for all new buildings.
