Many countries around the world, especially third world countries, are experiencing the negative effects of climate change.
To ease up on the effects of our wasteful lifestyle on Mother Earth, there is a movement to go “green” from about everything and anything under the sun, and one of these movements are focused on the promotion of eco-friendly homes.
Don’t be alarmed if the first thing that popped into your head are houses made up of alternative or recyclable materials like old plastic bottles or used container vans. Fear not, because eco-friendly homes are much more than just about those stereotypes.
In fact, you can actually do a property renovation of a regular house into an eco-friendly home without having to source old container vans. The secret is to just making your house airtight! Why? Because an airtight home is the key to an energy-efficient property. And the less energy we, regular blokes consume, means great news for the environment.
Before I go any further, having an airtight home doesn’t mean no oxygen will ever come in and out of your house. Airtight and breathability are two different things. Breathability is, broadly, a material’s ability to absorb moisture and then release it so that water vapour is not retained by the fabric of the building, also known as hygroscopic.
Having cleared that up. Here’s a property renovation checklist of the key areas that you have to focus on whenever you’re constructing an airtight home. They are the:
Walls, roofs, and floors are called the fabric envelope of the home. A very helpful property renovation advice I can give you is to look out for the junctions between these areas, because these are points where air usually escapes when the construction or build is not well done.
Windows and outdoors doors are also critical points for airtight homes. The window frames must be sealed tightly with the adjoining walls, while the doors must also be sealed shut without any gaps in the top or bottom.
Despite the obvious benefits of building an airtight home, some people are still reluctant on making the switch because they aren’t quite sure how much it will cost them to do the renovation. Property renovation costs for an airtight home greatly depends on the quality of the airtightness and the materials you’re going to use.
For example, if you’re goal is to reach 5m³/hr, you’ll need 5 per cent more for the regular budget in an SIP build and a whopping 15 per cent for a masonry build.
On the filp side, however, airtight homes have cheaper heating costs compared to houses built without airtightness being considered. Homes with airtightness from 10m³/hr to 5m³/hr have been proved to consume 22 per cent less energy, while those which meet the PassivHaus standard have an astounding energy efficiency of 52 per cent. I don’t know about you, but that sounds like a ton of savings on utility costs in the long run and another achievement you can add to your property success with renovation.
