The recently released Climate Change Commission’s draft report for public consultation speaks of the need to reduce the domestic use of natural gas and LPG. This, and the inevitable depletion of the resource, will need to influence the way we design the water heating systems for our dwellings.

With New Zealand’s commitment to Net Zero Carbon Emissions by 2050, the built infrastructure sector of the economy will have a significant part to play if the target is to be met. The Residential Tenancies (Healthy Homes Standards) Regulations 2019 illustrates the need for lateral thinking.

The process of designing and selecting insulation materials for the thermal envelope of a building is not a simple task.

Heat Pumps are now well established as a heating source for the home which suits family life as it has been for the last decades, but will they have the same dominance following the disruptive game-changer of Covid-19?

‘Shovel-Ready’ is the adjective of the moment, but is it to be a 2019 descriptor or a 2021 descriptor? This will be important in 20 years time when the decisions about to be made will be well cemented in.

Windows form an important barrier and connection between the wide outside world and the cosy private environment of the building’s occupants. As the weakest point, attempts have been taken by industry to address the thermal vulnerability of this necessary building element.

With the current shortage of rain in much of NZ, especially in the North, it is appropriate to recognise the long-term change in rainfall patterns and to give serious consideration to having water storage for domestic use at most dwellings.

From time to time there are calls from various interest groups advocating that their section of the New Zealand Building Code needs to be updated or revised, including Clause H1 (Energy Efficiency).

With the growing acceptance that we must be much more clever with our use of the world’s non-renewable resources, we are well past the time when we can rely on long-standing assumptions, short-term thinking, and Green-wash. Objective assessments are urgently needed.

There are many products in the market each promoting their individual thermal performance, but when incorporated into a building the actual ‘real-life,’ performance becomes dependent upon the interaction of all the materials and products used in the construction.
