In New Zealand, approximately 10% of the population relies on rainwater collected from roofs for their daily water needs. There are also an increasing number of projects looking for sustainable and cost-effective solutions to harvest rainwater as a reliable source for drinking water. The key to ensuring the safety and quality of water lies in proper collection, storage, adherence to regulatory standards, and the crucial step of effective filtration.

Recent modelling by Jason Quinn of Sustainable Engineering found that improper glass choice and orientation could lead to over 33% increased risk of this specific house design overheating, as evidenced by the graph. What are some options that will reduce the risk of overheating from solar gain?

Recent membrane testing and technology allows some systems to work at lower falls. This creates an impact on the design scenarios in which the overall roof buildup has a height limitation.

In this article we look at some of the elements included from Version 3.0 onwards of the Ministry of Education's Weathertightness Guidance document which would be deemed ‘above code’, and discuss the whys, hows and wheres of their practical application.

This is a question that often gets asked. There are a number of options, and your product selection will depend on a few factors.

In this second part in our series 'A Guide to Structural Actions on Internal Aluminium Partitions', we look at frame deflections and loads that need to be considered when specifying partitions. 

Part 1: Structural considerations for internal aluminium partitions.

When designing a compliant level threshold system we have to cover off all the requirements of Chapter 7.3.2.1 of E2/AS1.

A ballast roof or brown roof is created when a roofing membrane has a layer of gravel, pebbles, or stones added as the finished layer.

Waste water in processing facilities such as factories for food and beverage production, or even commercial kitchens, can often present unique requirements on the drainage systems.
