Rate the environmental performance of your home with Homestar™
How well do you know your home? To check how your existing home stacks up in the warmth, health and efficiency stakes, Homestar™ provides independent advice and guidance on energy and performance improvements to the home, as well as professional design and construction services for residential new builds.
Developed by the New Zealand Green Building Council and backed by Government, the rating system aims to improve the standard of Kiwi homes by providing a comparison against a benchmark, so home owners can ensure their homes become warmer, healthier and energy efficient thus reducing their environmental impact.
It’s estimated over one million homes need to be improved to be:
Often you know your home is cold, draughty, damp or overheated but you’re not sure where to start improving it. The Homestar™ residential rating tool has been developed to help you get started. It is designed to help you identify what areas in your home need attention and give you guidance and ideas of what you can do to improve them.
Homestar™ has been developed to take into consideration the environmental building standards required regionally, by New Zealand’s unique climatic conditions. It allows for both self-assessments by the homeowner, using an online home evaluation report and specialist independent assessment by industry professionals that results in the issue of a formal Homestar™ certified rating.

What Resene products should you consider when undertaking renovations to improve your Homestar™ rating?
Resene CoolColour technology is available in a wide range of exterior paints and stains and performs best in dark colours that are the most prone to heat build up. It can be used for areas from roofs and weatherboards to decks and fences.
Although it may be hard to believe, these two colours behave the same in test procedures. The test procedure involves fixing thermocouples onto the backs of these panels (ensuring a good thermal contact); shining an infra-red light onto the painted side of the panels and plotting the temperature rise of the panels on the thermocouples.
The grey panel is a standard coating. The black panel uses Resene CoolColour pigments. The black Resene CoolColour panel has the same infra-red (heat) absorption as the standard paint finish on the grey panel, demonstrating the reflective benefits of Resene CoolColour technology.

On painted surfaces, mould looks like dirt, so it’s often hard to tell by looking at it what is actually mould and what is actually dirt. The most common type of mould is black, but others can be brown or green. A quick way to tell whether you are dealing with mould or dirt is by wetting the surface and rubbing. Mould will show up as slime.
Mould is a major cause of paint disfigurement. It destroys the paint's fresh clean appearance, and if left unchecked it shortens the life of the paint film. Unless removed within a few months of its appearance, mould penetrates the body of the existing film and once firmly established, will grow through subsequent paint coatings, impairing adhesion and ruining the appearance of the paint work.
You can’t just clean off mould with water and a brush, you need to kill it. To tackle moss and mould thoroughly clean down the surface to remove all loosely adhered material. Treat areas of moss or mould infestation with Resene Moss & Mould Killer, correctly diluted (see pack) with clean water. As soon as the mould has been completely de-colourised, which indicates it has been killed, wash thoroughly with clean water to remove residues and then allow to dry.
Consider getting Resene MoulDefender added to your paint as this is a mould inhibitor and gives your paint extra protection against mould. It is also in the Resene Kitchen & Bathroom range – Resene SpaceCote Low Sheen Kitchen & Bathroom, Resene SpaceCote Flat Kitchen & Bathroom and Resene Lustacryl Kitchen & Bathroom to provide extra protection against mould in wet areas.
Where you can open windows, doors etc and allow the air to circulate. While you can turn on air conditioners and heaters, some actually exacerbate the amount of moisture in the air. There’s nothing quite like a few windows open in good weather to really refresh the indoor air.
Resene SpaceCote Low Sheen Kitchen & Bathroom combines the durability and easy cleanability of a low sheen waterborne enamel with added anti-bacterial silver protection and the mould protection of MoulDefender to minimise bacteria and mould growth. Anti-bacterial silver protection is internationally recognised as a safe and healthy method of deodorising and sanitising surfaces that come in contact with skin, food and water.
Use Resene SpaceCote Low Sheen Kitchen & Bathroom on walls and complement with Resene Lustacryl Kitchen & Bathroom on trims and joinery. Or for a semi-gloss sheen throughout use Resene Lustacryl Kitchen & Bathroom formulated with anti-bacterial silver and MoulDefender for your walls, trims and joinery.
Quickly kill exterior moss and mould using Resene Moss & Mould Killer, or for a slower acting less work required option, use Resene Deep Clean. Resene Deep Clean is the simple, safe method of keeping all your outdoor areas free from moss, mould, algae and lichen. Simply spray or brush on and leave Resene Deep Clean and nature to do the work. Slow acting Resene Deep Clean gets right down to the roots of the problem, destroying the growth and combining with U.V. light and rain to weather off the remains to leave a Resene Deep Clean surface. Ideal for use on paths, patios, decks and other exterior cementitious, timber and painted surfaces.
Once you have cleaned off the moss and mould, consider using Resene Non-Skid Deck & Path on areas where you are more likely to slip. Resene Non-Skid Deck & Path has a comfortable grit texture that gives shoes and feet something to grab onto, reducing the risk of slipping over. This is especially idea for stairs, sloping paths and areas surrounding pools that become very slippery when wet.
Consider indoor air quality
Opt for Environmental Choice approved, waterborne and low or no VOC paint options wherever possible. Resene has an extensive range of Environmental Choice approved products suitable for inside and outside your home, from primers and sealers to paints and stains. These products are also waterborne so are quick and easy to clean up in water and generally much lower odour than solventborne products.
Resene Zylone Sheen VOC Free, combines the popular low sheen of Resene Zylone Sheen without the unwanted volatile organic compounds (VOCs) for better indoor air quality. Or for a more durable finish you can choose Resene SpaceCote Low Sheen, which combines a desirable low sheen finish with low VOCs and an easy care surface.
A VOC is a volatile organic compound – in the case of paint, this is solvents that are released into the air as the coating cures. Most waterborne paints now have VOC levels of 100gms or less per litre. Traditional solventborne paints have considerably higher levels of VOCs – sometimes 500gms or more per litre! Improved air quality can help prevent headaches, asthma, nausea, respiratory complaints and allergic reactions.
