Unified Facilities Criteria (UFC) – Solar Heating of Buildings and Domestic Hot Water (2004)
This handbook was released by the US Department of Defense in 2004. It presents design criteria and cost analysis methods for sizing and justification of solar heat collectors for potable water and space heaters. Sufficient information is presented to enable engineers to design solar space conditioning and water heating systems or conduct feasibility studies based on solar collector performance, site location, and economics. Both retrofit and new installations are considered.
Heat Transfer Fluid from Corn
The US-American based renewable system supplier Solar Panels Plus LLC (SPP) has launched an alternative to petroleum-based propylene glycol. The new heat transfer fluid made from corn is completely renewable and biodegradable. “The underlying corn glycol product is made by chemical giant DuPont and we developed our own formula for the production of an efficient heat transfer liquid”, says SPP COO John Williams.
