Abstract
 This paper describes a simple graphic method, derived from ASHRAE techniques but easier, which allows architects to size solar Domestic Hot Water (DHW) systems in preliminary design before any details are known about the building. A simple table of hot water loads on a per unit area basis by occupancy type allows loads to be sized in a rough and approximate, but quick way. The second part of the paper gives a quick method, again based on ASHRAE methods, but quicker, for spacing rows of photovoltaics or solar heat collectors on flat or sawtooth roofs such that one collector does not shade another.
