20. Building orientation is ideal for the use of
solar radiation by an active system
VAF, SOCIAL HOUSING
SARRIGUREN, NAVARRE, SPAIN
21. OPERATION
The air confined to the chamber of the façade is heated by solar radiation and driven into the indoor spaces
providing calorific energy.
On hot days the chamber opens to the outside to prevent overheating

22. DESIGN
The exterior sheet is a corrugated steel black lacquered . Its thermal properties (high absortion, low
thermal inertia, high thermal conductivity) allow to transfer the solar absorbed heat to the confined air

this chamber to the HVAC system

25. In order to control the incident solar
radiation a sunshade, consisting of
an extension of 1,80m of the
concrete structure for each plant,
has been placed along the façade
The generated space is used as an
evacuation emergency platform
The sunshade comprises security
laminated glass elements 8+8 with
reflectant polyvinyl butyral
VAF, TRACASA HEADQUARTER

26. PERFORMANCE
On Winter the solar radiation is only allowed to incide on the platform components, avoiding direct
incidence into the indoor space. During Summer sunbeams are reflected to prevent the indoor
space overheat

39. Results
The air flows through the façade at a variable speed between 0.2m/s and 0.5m/s
Considering the air flow and the temperature rise, the façade supports 30kW per day, an equivalent to
12.5kw/m of active façade
In a housing with an energy performance A, it represents 3% of the HVAC energy consumption

•Automation of the façade
•Integration with the HVAC system
•Development of the fixation systems
•Integrate intelligent systems in the façade
