Passive constructions are designed to be highly efficient, but depending on their climatic location they will need to cover a small energy consumption. Renewable energies are ideal for this purpose, being able to make use of technologies such as solar, wind, aerothermal, geothermal, biomass or biogas energy to supply this small demand.
The most common option in the residential sector in Spain continues to be solar panels (both photovoltaic and thermal) given the abundance of sunny days, simple installation and efficiency in production. This has been the case in Ca Na Lola, a Passivhaus home in Mallorca designed by KLARQ, which has an 10Kw installation of photovoltaic panels and batteries for storage, being able to transfer any surplus of electricity to the grid.
The current CTE or Technical Building Code, establishes that renewable energies must be used in housing projects and limits the consumption of non-renewable primary energy, so we expect to see a great boom in Spain within the renewable sector in the upcoming years, especially in passive houses.
At KLARQ architecture atelier we are committed to sustainability and innovation, striving to generate the minimum carbon footprint and to use renewable energy in our architectural projects whenever possible.
