Homestar is the independent system that rates the health, comfort and efficiency of New Zealand homes, on a scale of 1-10. A rating of 6 Homestar or higher provides assurance that your home will be warmer, healthier and more energy efficient to run than a typical new home design.
A HomestarTM rating takes into account energy, water, waste, ventilation, health and comfort, and other environmental factors of a house. We can predict the energy consumption of your new home with our design software and the HomestarTM evaluation tools.
- Catalyst Homes is committed to designing new build houses that achieve 6 HomestarTM or higher ratings
- Achieving a 6 HomestarTM home will cut power bills by around 50%, yet only costs a few percent more on the new build cost
- An 8 HomestarTM home or higher is so energy efficient that it may achieve zero nett energy usage
- Building to the current NZ building code will achieve 3 HomestarTM but most older homes are lower than this.
Talk to our team about how we can design a new home for your family, which will be warm, dry, healthy, low cost to power, and bear a 6 HomestarTM rating or higher.
With sustainable home design, Catalyst Homes have a small environmental footprint. The houses built to reach 8 HomestarTM rating or higher are designed to target zero energy use through a combination of optimum thermal performance and of PV solar and water heating panels to provide energy to the integrated systems.
We reduce the investment required to achieve a good rating, as it is our policy to design HomestarTM features and requirements into all Catalyst Homes plans. Attempting to upgrade an existing home design to meet higher HomestarTM ratings very seldom works and can be very costly.
It is accepted that homes with a high HomestarTM rating will achieve higher resale values and return more than the investment made in the improvement.
HomestarTM ratings are assessed by qualified professionals and certified by the New Zealand Green Building Council. Catalyst Homes has a Certified HomestarTM Practitioners on staff.
We have designed a number of 7 HomestarTM and 6 HomestarTM dwellings for clients in Auckland and north of Auckland, which showcase our sustainable architecture experience.
