Free Tool Scores Your Home's Winter Health Out Of 100 In Under Two MinutesA free online tool that scores your home's winter health out of 100 has launched, giving Kiwi homeowners a two-minute snapshot of how their house is coping with the cold. Damp, poorly ventilated houses are linked to mould growth and respiratory issues, and they also cost more to heat. It covers the basics that make the biggest difference to a home's health over winter, including how much moisture is building up inside, how well the house holds warmth, and whether stale air has anywhere to go. At the end, users get a score out of 100 and a breakdown of where their home is doing well and where it is falling short. The quiz is designed for anyone living in a New Zealand home, whether they own it or rent it.
