The new Academy consumes 30% less energy than required by federal code. The planted roof provides a thermal insulating layer for the building that help prevent overheating during the summer months and reduce energy needs for air-conditioning.
While the Academy uses new “green” technologies, it also takes advantage of simple, traditional engineering techniques involving use of natural light and ventilation.
At least 90% of regularly occupied spaces have access to daylight and outside views, reducing energy use and heat gain from electric lighting, whose controls are included as automatic dimming linked to external light levels to ensure that a minimum of electric lighting is used any moment; also openings in the roof domes creates a stack effect on the exhibit floors, drawing in cool air from below and exhaling warm air out the roof meanwhile operable windows are employed in staff offices.
The roof is a green roof which has all the benefit linked to this technology indeed soil moisture, combined with the phenomenon of thermal inertia, cools the inside of the museum significantly, thus avoiding the need for air-conditioning in the ground-floor public areas and the research offices along the facade.
The choice of materials, recycling, the positioning of the spaces with respect to the natural lighting, natural ventilation, water usage, rainwater recovery and energy production: all of these design issues became an integral part of the project itself, and helped the museum obtain LEED platinum certification.
