UFC 3-440-01 Design – Active Solar Preheat Systems is one of those documents is a UFC Document.
Unified Facilities Criteria (UFC) documents provide planning, design, construction, sustainment, restoration, and modernization criteria.
UFC Documents also apply to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L) Memorandum dated 29 May 2002.
The United States Army Corps of Engineers (HQUSACE), Naval Facilities Engineering Command (NAVFAC) and the Office of the Air Force Civil Engineer are responsible for administration of the UFC system.
While this really pertains to large buildings and contracting companies, I add it because I assume a person interested in building a home that has a reduced energy footprint would find this useful.
I figure a thinking person can glean some tips and ideas from a document like this. When you talk about the scope of utility cost for military buildings heating and cooling can cost billions annually, so the US Department of Defense has an interest in designing buildings that reduce the use of fossil fuels in the heating and cooling of those buildings.
