I recall watching a program on green construction on KQED and the Federal Building in SF and how it was built. From Wikipedia: > The building was designed to be a 'green' building consuming less than half the power of a standard office tower. Utilizing natural light to illuminate 80 percent of the building helped it achieve worldwide recognition as the first Federal Building to be certified under the USGBC's Leadership in Energy and Environmental Design (LEED) criteria. Its southern wall is draped with translucent panels of perforated stainless steel (3 by 8 feet in size), intended to accumulate solar heat and thereby create an upward air flow, which in turn causes cooler air to enter the building through sensor-controlled windows, achieving an air conditioning effect. The result has been criticized as unsatisfactory by employees working in the building, which has received low workplace satisfaction ratings. And an article on it - https://www.govexec.com/pdfs/green/080108gsa.pdf https://www.govexec.com/pdfs/green/080108gsa.pdf There are some neat things they tried there.
