A building's program scopes the project by outlining how space should be used based on the building’s goals, conditions, and objectives.
Part of a building’s sustainability is related to its land use. Continuing to convert more wild lands and farmlands into building sites is unsustainable, and there is much land area available in cities that can be redeveloped more densely and sustainably.
Energy use is often the largest source of a building’s environmental impact. To improve your building’s energy efficiency, you need to understand its site, program, and energy loads.
