TS Constructions homes at The Cape

Blower door tests prove Cape homes are constructed to the highest standard

Sustainable homes are well sealed and remain comfortable in all weather conditions

TS Constructions have constructed over 20 homes at The Cape to date, and over the past two years have quietly introduced blower door testing to all of their builds to validate the performance of their homes. All blower door tests are being conducted by accredited, independent technicians from Baw Baw Sustainability Network.
​
A blower door test​ is a test of how airtight a house is to ensure that when a resident warms or cools the air in the house, the air doesn’t leak out and waste hard-earned energy dollars and reduce comfort levels. Air tightness is as important as high R-values in your walls and ceiling – a home can have great insulation, but if there are air gaps and air is leaking out (or in) it will increase the running costs and energy usage of your home while reducing your comfort levels.

To conduct a blower door test, a qualified technician covers an exterior door with an air tight membrane and runs a computerised fan connected to a laptop according to an international standard testing process. By measuring the pressure difference between the interior and exterior of the house, the fan flow and knowing the volume of air in the house the technician can tell you how much air is leaking in and out. Blower door test results are measured in “air changes per hour at 50 Pascals” (ACH50). This is the measure of how many times in an hour your house leaks all the air inside of it!
​
A 2015 CSIRO study of 129 recently completed 6 star homes across Australia showed that almost half the houses tested were above 15 air changes per hour which is considered quite leaky and inefficient for a newly constructed house. Imagine trying to heat all the air in your home 15 times every hour on a cold windy day and you can see how costly and uncomfortable it would be.

TS Constructions have been undertaking blower door tests to ensure their homes are sealed to a high standard, and to train their staff on the common mistakes that can lead to a leaky home. All trades working on their homes, including builders, plumbers, electricians and other trades have been invited in to watch these tests take place, and to learn how to seal up these homes to a very high standard. 

The homes tested to date by TS are showing an average of below 5 air exchanges per hour. TS Constructions Director Tony O’Connell told us “the blower door tests are a great training tool for our staff, and provide an extra level of confidence to our clients that homes are built to their badged star ratings and are well insulated and sealed to stay comfortable year round and reduce energy loss. We believe all new houses across Australia should be pressure tested upon completion to ensure people are buying well sealed, high performance, energy efficient homes”

Thoughtful passive design with high standard of construction creates homes that are comfortable all year round, even during Australian heat waves. Come on down to The Cape and experience these homes for yourself!
