ENERHAT (Energy Housing Assessment Tool) is a freely accessible application that makes home assessment for homeowners, tenants, and real estate agents alike easier. This application has multiple functions; it enables all parties to access information on the energy performance and the state of conservation of residential buildings, to compare the energy efficiency of housings, to assess the investment needed to carry out home improvements, and to apply for grants or subsidies to carry out improvements.
ENERHAT has been developed by the research group ARC Engineering and Architecture La Salle in Barcelona, Spain. This evaluation system is a useful tool for local, regional and national authorities, building professionals, and building occupants to assess the most relevant energy data of the housing. According to the official website, ‘the application integrates the data obtained from the Energy Performance Certificates provided by the Catalan Institute of Energy, the cadastre and the census sections, together with geographic information.’
This easy method empowers homeowners and tenants to access free information otherwise buried in multiple sources and formats, presented in an understandable way to guide non-experts to take a decision on improving energy rating of their homes.
