Eight dwellings near San Sebastian on the Bay of Bisay<\/strong>, Pasaia<\/strong><\/p>\n<\/div><\/div>\n\n\n

\n

The EU-funded project HAPPENING’s concept is based on cascade heat pumps in refurbished multi-family buildings in order to allow for ‘tailor-made solutions’.<\/p>\n<\/div>\n\n

In the North of Spain, next to San Sebastian lies the small town of Pasaia. In this mild climate zone, a multi-family building was constructed in 2008. It consists of eight dwellings, each of which has an approximate size of 75 square meters.<\/p>\n<\/div>\n\n

\n

The (Basque Country) state funded company Alokabide<\/em> owns this building which was built with renewable energies in mind as it had Solar Thermal components installed but still drew both Domestic Hot Water (DHW) and Space Heating (SH) from individual gas boilers with 100l TES in each dwelling.<\/p>\n<\/div>\n\n

\n

By the time of refurbishment, the Solar Thermal parts were out of order. Still, the building is owned by the aforementioned company as part of the public social housing policies of the region.<\/p>\n<\/div>\n\n

\n

Before refurbishment the building had an energy consumption of ~32,3 MWh\/y (SH 6 DHW) + 12,8 MWh\/y (electricity consumption)<\/p>\n<\/div>\n\n
