DHW + PV: solar PV top-up for domestic hot water

DHW + PV: all-electric hot water heating for Passive houses, with surplus solar PV top-up Energy consumption from DHW use is often higher than heating and cooling requirements in a residential Passivhaus. This is mainly due to the large losses inherent in storing and recirculating hot water, and because heating and cooling demands are very low, thanks to an optimised fabric design that…

Hygrothermal calculation of a bio-based timber frame wall module

Hygrothermal calculation of a bio-based timber frame wall module Dynamic hygrothermal simulation and full-scale validation of a structural insulated panel made from bio-based materials. Given the environmental impact of the construction sector- responsible for 40% of the total primary energy consumption of the European Union- reducing both the embodied energy of materials at manufacturing stage…
