How much energy we use affects carbon emissions, making it important to know current levels of household energy use. BRANZ’s HEEP project looked into this but technology changes means it may be time to revisit.
Recent BRANZ research into the airtightness of apartment buildings has prompted a shift in thinking around airtightness and ventilation. BRANZ now recommends that residential buildings are mechanically ventilated and are built to an airtightness target.
This project measured the airtightness of multi-unit residential buildings and compared these with the existing data on housing airtightness. We know our houses are being built more airtight, but what...
The research assessed risks of moisture ingress into retrofitted wall insulation when the underlay is either absent or compromised by installation holes drilled through cladding. The project provided guidance for...
