Laboratory Testing of Small-Scale Active Solar Façade Module

Buildings are linked to a significant untapped energy saving potential, accounting for 40 % of European Union’s (EU) final energy and 36 % of CO2 emissions. Energy efficient building envelopes plays the key role to achieve decarbonization of the EU’s building stock by 2050. Active building envelopes...
