Description

Casa SG Joaquim is a Passivhaus Plus certified home, designed by architect and Passivhaus Designer Sergi Gargallo of SgARQ Passivhaus Architecture, and certified by Oliver Style of Praxis Resilient Buildings. This terraced home has a façade to the main street and the interior patio to the rear of the property. 

The building consists of a ground floor and a first floor with an accessible roof terrace, garden and swimming pool. External walls are insulated with 100mm of external insulation, eliminating structural thermal bridges, with 200mm of thermal insulation on the roofs. 

High-performance windows and a very low level of air leaks- tested on-site with a Blower Door test- reduce heat losses in winter and heat gains in the summer, keeping the house comfortable with minimal energy consumption.  

The home has a whole house balanced mechanical ventilation system with heat and humidity recovery, with a Zehnder ComfoairQ 350 ERV unit, certified as a Passivhaus component for hot climates. To reach Passivhaus Plus, 18 solar photovoltaic panels were installed on the roof, forming a 6.7 kWp array. PHPP energy modelling indicated the home will have an annual consumption of around 4282 kWh/a, with an on-site photovoltaic generation of around 7903 kWh/a.
