This resources outlines what is proposed in the current H1 Consultation, as well as variants that are possible considerations.
It then outlines all of the variants that are missing!
While the proposals are a first step, a longer term focus is needed.
The industry tends to take multiple years to adapt to any change and many will see this as a first step towards an unknown end game.
This resource outlines the roadmap to efficient and effective change.
There are plenty more sensible options beyond what is covered in the H1 consultation.
For example, can we save money on the products that are used? Answer, YES.
And, can we save money on better products that are used? Answer, YES.
Check out this comparison between PIR Rigid Board Insulation and Fibrous Rockwool Insulation.
The structural minimum thermal insulation is regulated in NZBC Clause H1. Minimum R-Values (wall, ceiling, roof structure) are currently defined and being reviewed for improvement.
However, these only address the R-Values of the components, but in reality, building services components (heating, ventilation, air conditioning) and the thermal insulation (type, thickness, properties) must be taken into account.
The Australian guidelines for indoor air quality are specific, targeted and closely aligned with international guidelines. If Australia can have just great standards, why can’t we?
Our recommendation is to create indoor air quality standards that are in line with these Australian standards.
Check out the comparison of the current Australian guidelines versus the International guidelines.
It may seem intuitive to keep adding more insulation, but this is not the only way we can improve the performance of our home.
Read more about what improvements in building performance can be made from upgrading window components above H1 requirements.
In an attempt to ensure buildings are more energy efficient, MBIE prepares to consult on changes to support higher-density housing. We dived deeper in why the proposed changes are still not hitting the mark, and why Building Code standards in New Zealand need to be properly addressed.
The first (of nine) points we address – The Performance Metric
What is a Healthy Home?
We already know what acceptable, healthy indoor conditions are. Decades of research has shown a defined range of indoor conditions reduce the risk of adverse health impacts.
No matter what house you live in you can improve your health if you live within this range of healthy indoor air quality.
This guide explains what a Healthy Home is, why Oculus are trying to achieve it, and what any New Zealander can do to their own house to improve their health.
After researching the fire compliance of cladding in New Zealand since 2017, some may say advice from Oculus is conservative, but they prefer to think of it as design for the safest and best economical outcome.
This document outlines the compliance pathways and advice that follows international best practice.
What is the difference between a cold roof and a warm roof, and why should we build with warm roofs?
How does a warm roof impact the performance of my home?
What differences in mould growth is seen with little-to-no insulation compared to insulation in a cold roof? This guide explains it all.
Many buildings in NZ are still being built with “natural ventilation” being relied upon to provide adequate fresh air. While this solution may be “acceptable”, it is not actually effective, because it is usually based on hopes and wishes rather than proper engineering design.
This document explains the various types of ventilations systems, how they perform in the home, and what we should actually be working towards.
You’ve heard all of the ads on radio and tv, and you’ve even seen insulation being advertised on social media, and you’re ready to reduce your power bills and spend the money on a nice, warm blanket for your walls.
You’ve got the right idea, but there are many different ways to insulate depending on the existing building, and few things you need to consider BEFORE you start insulating.
This resource will help you understand insulation and which option is best for your home.
We all know it’s nice to keep warm in winter, but what happens in spring and summer when we can’t get rid of the heat?
Of course you can install an air conditioning unit, or perhaps a heat pump with a cooling function – but not everyone has the means to do this, so here are three cost effective solutions to help keep you and your home, cool, dry and comfortable.
Healthy homes are hugely important to the health of our nation. Whether winter is coming, or has already arrived we all need to work towards having a warm, dry and comfortable home, and these three products won’t break the bank in helping you achieve that.
