Abstract: This work analyses integrated capture of solar energy and consumption statistics in a single‐
family house of real estate developments in Concepcion, Chile, in order to assess self‐supply for net‐
zero, plus‐energy and/or powerhouse aptitude. A current house model is selected, and partially
modified to improve its thermal performance and solar capture. Then, alternatives to integrated
photovoltaic and thermal solar technologies are studied (BIPV, BISTw, BIPVTa and BIPVTw). Energy
demands on typical seasonal days are compared to production in different combinations, then energy
deficits and surpluses were obtained. An annual energy balance of approximately 174% has been
estimated with the use of Building Integrated Photovoltaics technology only, and with BIPVTw and
BIPVTa technologies, a maximum of 251% of the energy demand is possible to be produced. However,
additional actions must be considered to compensate for daily and seasonal differences, to fulfil an
energy self‐supply and to feed the urban grid or other services.
