BUILDING ENVELOPE

For energy, it is always best to start with the building’s envelope (the

skin, openings and roof of a building’s exterior). The more efficient the

envelope, the less energy will be required for conditioning of the interior

spaces and the spaces will be much more comfortable to occupy.

Another goal of this approach is to make the ongoing utility costs as low

as possible (and thus concentrate more of the budget on services), as

well as to make the buildings more comfortable and easy to maintain.

Although the existing windows are insulating glass in aluminum frames,

they are old and not in great condition and are not as energy efficient as

current ones. The windows and exterior doors should all be replaced

with new, energy efficient glazing systems. A thermally broken,
