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.

The industry needs to work to lessen inefficient delivery of materials, building waste and the movement of the workforce in order to reduce our environmental impact. 

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).

There are many reasons to believe that the future is bright for the offsite construction sector in New Zealand. 

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.

While in the normal course of events, most newly constructed homes in an urban setting can achieve a 6 Homestar rating, if there is an aspiration for higher ratings, then there is value in looking at where points can be gained at an early stage in the design process. 

The results of a simple experiment to demonstrate the value of well-fitted curtains.

As an incentive to sustainable housing, in mid-April the ANZ Bank announced that it is offering reductions to some of its interest rates and fees, subject to particular conditions, if the property being financed has a minimum Homestar rating of 6 stars.
