User needs for solar decision-making tools: The homebuilding industry

The need for decision tools and design tools to be used by decision makers considering using solar energy in the single-family residential construction sector was studied. Three builder groups were found based upon decision making patterns relative to innovation and a five-step decision process. Eleven existing design tools were reviewed against identified user needs. The principal conclusions are that decision tools are largely lacking and design tools do not easily fit user needs. Recommendations for further study are made.
