How does a library building reflect not just the aesthetic and historical context of the community, but respond also to its social and environmental priorities? The answer lies in a concept known as “sustainable design” or “green building.” It starts with the creation of a collaborative approach by the construction team to ensure that the building maximizes efficiencies in the operations of building systems which lead to energy savings, minimal environmental impact, and a healthier interior environment. Here are just a few ways the new Albert Wisner Public Library will engage the concept of sustainable design in the construction of a new building:
One of the key areas for consideration is energy usage and indoor comfort lies in the heating system.
The new library include a geothermal heat pump system that uses very deep closed loop wells to pump liquids into the ground and use the Earth¹s natural steady temperature to heat or cool the liquid, depending on season, before pumping it back though the building to temper individual areas and spaces. No fuel oil or natural gas is expended in this process, saving money and vital earth resources.
The windows in the new library have been designed to maximize the amount of natural light, increasing ergonomic comfort and minimizing electrical lighting requirements. Technologies allow the lighting control system to adjust automatically to the amount of sunlight present, raising and lowering the number of artificial lights automatically. And, in case you¹re worried about the amount of heat gain from those large expanses of glass, new technologies help us there, as well. A special glass is specified in the south facing windows to minimize heat gain while allowing natural light to pass through. You may also have noted glazing on the north walls. This allows the staff areas and even the Community Room to receive a very even, non-glare light during the day. This glazing is specified to minimize heat loss.
