ShowPass is both an apartment building and a showroom open to public to convince on the benefits of Passive House certification. The building has been renovated and harmonised with the urban environment. To preserve the original aesthetic, the insulation has been made inwards, using mineral calcium silicate.

A detailed monitoring of comfort and energy data has been ongoing since 2021 and data is continuously analysed to demonstrate feasibility of CO2-neutral buildings in this type of climate. A Life Cycle Cost calculation also shows that the building recovers additional costs in a few years.

Energy consumption

Primary energy needs: 4,00 kWhpe/m².year

Calculation method: RD: 47/2007

Breakdown of energy consumption: The PE consumption is following the Spanish EEC-calculation method, taking into account the PV production. The following values are taken from PHPP calculation, including all electric consumptions (without PV):

• Heating: 22%
• Cooling: 21%
• DHW: 21%
• Electricity (PH-procedure): 35%

Initial consumption: 102,00 kWhpe/m².year
