We now have a significant number of houses that are at least 60 years old. Should these ageing houses be renovated or demolished, and which option is more popular?
A BRANZ survey of people living in medium-density housing found significant concerns about property maintenance, including issues with the body corporate and, for renters, a reluctance to complain.
Durability information is currently in high demand. To address this, BRANZ is developing an interactive database of durability and compatibility information, designed with a range of users in mind.
Some building materials degrade when exposed to sunlight. Research has identified a way to mark building wrap with ink that fades, indicating how much sun exposure it has had.
A new BRANZ project is developing a web-based tool so designers and builders can easily give homeowners a project-specific record of the materials and finishes used and their maintenance over the life of the building.
Sunlight causes plastic to degrade, but not all types are affected to the same extent. Research at BRANZ is investigating the lifetimes of a range of materials in different parts of the country.
Two long-running BRANZ studies are investigating the durability of rigid PVC wall claddings and polycarbonate sheeting products. How are these materials lasting, and what can we learn?
Polymeric building materials can perform poorly under our very high solar radiation and uv levels. That makes it very important to confirm the building materials you are using have the appropriate uv stabilisers.
Accelerated weathering methods are often used to predict the service life of building materials and components in our challenging climatic environment.
Are we moving towards ‘dashboard’ displays in our buildings where sensor systems will warn of degradation in building materials?
