Evap Cooling, keeping you cool in winter?

Evaporative cool works very well on dry, hot days, but on humid is rendered useless and costs significantly to heat your home in winter, during the colder climate months. Efficiency Matrix conducted air tightness testing with and without evaporative cooling on a 15-year-old home in Melbourne, Australia. The Air leakage difference in a home with evap cooling can be as high as 10ACH@50Pa difference and in this video we demonstrate how bad evap cooling can be to the detriment of your heating performance of your home.

Streamlining the Air Tightness Testing Process

Efficiency Matrix has invested in mobile phone app development to significantly improve efficiency and the level of quality in its reporting to its customers. Air Tightness testing is great, but if all the points of air leakage and thermal insulation inconsistency is not captured and reported on, all of this information quickly gets forgotten for future remediation. Efficiency Matrix has developed an in-house app that can be used with limited internet connectivity and can machine gun capture air tightness, thermal insulation inconsistency defects with an integrated flir thermal imaging camera and general defects. The system has now been designed to go completely paperless where defects can be divided up to individual trades, and the app can now work with metric as well as imperial measurements. Building performance construction auditing for an as-built verification process.

Passive House inspired home, finding the gaps to achieve .6ACH@50pa

Mark Pohlner and Efficiency Matrix go on a witch hunt looking for air leaks in an already air tight home, which is using an internal wrap as its air barrier. Air Tightness is a number game, and in this video we talk about some of the little things that add up to air leakage in quite a detailed home, that paid careful attention to the details to improve insulation consistency and air tightness.

ecoEVO design Episode 8

Same builder 12 years later, what has changed? Air tightness – in this video we compare a newly constructed home with an older home, where energy efficiency was always at the top of the list.

Air tightness the missing piece of previous generation homes. Air tightness being recognised as a key component to manage building longevity, better air quality, and better performance in maintaining comfort. In this video we compare a modern project, which has endeavoured to create a better high performing building envelope, compared to one that had more emphasis on positioning, double glazing and insulation consistency only.

How much can an unused fireplace cost you in heating?

Fireplace draughts/chimney air infiltration can easily be the single largest contributor of air leakage in homes throughout the world. Next in line would be evaporative coolers and then exhaust fans without draft stoppers. Anyway, this is a quick video, that helps people grasp just how leaky fireplaces can get, and gives people a good start to improve the overall performance of their building envelope for heating and cooling. In this video we blower door test a building with and without the fireplace isolated.
