FYI: The Brooklyn Children’s Museum’s $39 million expansion will include a bevy of environmentally-conscious designs that the museum claims will make it an industry leader in “green” planning. The design includes a geothermal heating and cooling system and solar panels, both firsts for New York cultural institutions. It also includes sensors to bring lights on only when rooms are occupied and to dim them when there’s sufficient natural light, along with a carbon dioxide sensor that will adjust the ventilation system according to how many people are in a space. Museum officials estimate the design will save the city more than $100,000 a year in energy costs. [12/13/02]
