Results: Actions to reduce dampness
We were very surprised to see how few people had picked up on the recommendations to reduce moisture and dampness in the home.
In particular, only 6.7% acted on the recommendation to install a rangehood or kitchen extractor, and only 7.2% installed bathroom extractor fans.
Why is this important? Air that is laden with moisture is harder to heat - you will spend more energy and effort trying to heat it than you need to. If you can’t get your house warm enough, moisture in cold air will condense on cold surfaces such as un-insulated windows and walls.
Condensation is a breeding ground for mould, mildew and dust mites. These are known to be bad for your health, especially if you have a respiratory condition such as asthma. More colds and flu means more doctors’ bills, more prescription charges, more time off work and school.
Kitchens and bathrooms are major sources of moisture into your home, with the average shower generating a litre of moisture per person, and 3 litres per day coming from cooking. If this moisture is not moved out of the house, it adds to the moisture the air inside your home is carrying.
Two simplest and cheapest things that you can do are:
1. Install an extractor fan in your bathroom.
2. Install a rangehood over your stove.

This report presents self-reported and monitored data from householders participating in the HomeSmart Renovation Project. It describes the profile of those householders, their perceptions of house condition, and their past, intended and actual renovations. It considers the profile of house performance of the subset of householders whose dwellings were monitored for temperature and the impact of renovations on electricity and water consumption.
