Top 5 Air Leaks that make Australian Homes suck

Johnny K — Sun, 21 Jan 2024 22:04:02 +0000

Air leaks in homes can significantly impact indoor air quality, insect and pest ingress, and energy efficiency:

1. Indoor air quality: Air leaks can allow outdoor pollutants, such as dust, pollen, car exhaust, and industrial pollutants, to enter the home, worsening indoor air quality. This can be especially problematic for individuals with allergies, asthma, or other respiratory issues. In addition, moisture can also enter through leaks, potentially leading to mould growth and further degrading air quality.

2. Insect and mouse ingress: Gaps and cracks in a home’s exterior can provide easy entry points for insects and other pests. Sealing air leaks helps to close off these entryways, preventing pests from entering the home and causing potential health-related issues or damage to the property.

3. Energy efficiency: Air leaks can substantially impact a home’s energy efficiency. Leaks allow warm air to escape during the winter and enter during the summer, which forces heating and cooling systems to work harder to maintain comfortable indoor temperatures. This additional work results in higher energy consumption and increased utility bills. Addressing air leaks is important for maintaining a comfortable, healthy, and energy-efficient home. It involves identifying and sealing gaps and cracks around windows, doors, and other entry points with caulking, weather stripping, and sometimes more substantial repairs or insulation improvements.

Bulkhead Air Conditioning can be bad… Very Bad!

Bulkhead Air Conditioners look fabulous and they are usually in higher-end homes or apartments. They are usually recessed into a wall or false beam.
In the majority of cases, these systems are installed in a terribly leaky roof, the air conditioner is not connected to the building envelope. So, asthma and hey fever sufferers can have massive problems on certain days.
Airtightness is pivotal for building performance, and these air conditioning systems can contribute to significant air leakage in the conditioned environment of your building/home.

Mini-Split Air Conditioner Install Tips VS Gas Ducted Heating and Evap Coolers.

Splits Systems VS Ducted Systems, how do they interact? What should I go for?

Ductless VS ducts. Mini Split systems are really efficient. Can you even compare these systems to a gas ducted heating system or an Evaporative cooling? The Evaporative cooling system and ducted heating system can be responsible for some serious overheads of heating and cooling in a home. We cover some of the pitfalls of split system installations and explain why a split system combined with a well-insulated/airtight home is the best way to go in the future. If you are organising a new split system, make sure you DIY the air tightness part while the installers are doing the install.

Evaporative Cooling makes your home energy INefficient for heating!

Evaporative cooling contributes to significant air leakage which in turn affects heating and cooling energy efficiency. In Melbourne, there are 176 hours with 30˚ C plus temperatures and 1336 hours with less than 10˚ C temperatures in 1 year. With these numbers should we be worried about energy efficient cooling or energy efficient heating in the southern parts of Australia? Efficiency Matrix goes over the negatives of having evaporative cooling installed. Evap cooling is a serious contributor to air leakage in homes, and although it may save you money, cooling in summer, it can be useless on humid days and cost a lot of money in heating during winter. Cooling an individual room with an inverter split system may be a more economic solution and spending time on improving the air tightness and insulation effectiveness of the building envelope, which will benefit summer and winter energy consumption.

WALL VENTS: remove them? Reduce draughts and save energy.

Wall vents have been around for a while, but they aren’t being put into new homes. We go over why and talk about a good super cheap way in substantially reducing air leakage from them. Look out for unflued heaters though, a home installed with these devices can be dangerous when a home is not well ventilated. Watch the video for more information.
