Whether you are living in your own home, renting it, or looking to sell, take a small amount of time to make big improvements on the living conditions.

Your home is where you spend most of your time so it's important to make sure it's a healthy living space. Essentially that boils down to keeping it warm and dry. Unfortunately many Kiwi homes are too cold and damp. This makes us more susceptible to illnesses such as asthma and respiratory infections.

To banish the bugs, there is a raft of simple home improvements you can make. That will not only ensure your home is better for you but will also benefit the environment. Putting the effort in can help save money and enhance your property's appeal if you sell — a win all round.

The Energy Efficiency and Conservation Authority (EECA)'s three essentials for a healthy home are to warm it up, dry it out, and air it out.


The number one priority is insulation. EECA's technical analyst Christian Hoerning says good quality insulation helps keep the heat in during winter and out during summer: "This makes your house easier and cheaper to heat properly, and more comfortable and healthy. The priority for insulating your home should be ceiling and underfloor, followed by walls."

Next, heating. The World Health Organisation recommends we heat our homes to at least 18C.

That's partly for health and comfort, but also reduces the risk of mould and damp. The most environmentally-friendly and cost-effective heat sources — particularly for larger rooms — are energy efficient heat pumps or modern wood or wood-pellet burners.

You also need proper ventilation for good air quality and to remove excess moisture. And no, living in a draughty house doesn't count. According to Hoerning, adequate ventilation means opening windows at opposite ends of the house every day and using externally venting extractor fans in the kitchen, bathroom and laundry.

"It's also important to track down any underlying sources of damp in your home because some of these — such as leaking pipes — can be relatively simple to fix," he says.

If your property has accessible subfloor spaces, Hoerning recommends installing a ground moisture barrier. This stops moisture rising up from the ground into the house.

Need to replace an appliance or lighting? It pays to go green.

Hoerning says: "It costs as much to run one old-fashioned incandescent lightbulb as it does to run a modern, energy-efficient television. LED lightbulbs are now an affordable option that will save households money."

Adopting these basic measures to improve your home will pay back big time when it comes to health — for you and the planet.
