Australian First – A Ventilated Dry Ridge now in Australia
Ventilating a roof space to control comfort levels in the living space is fast becoming an accepted requirement in Australia. For many years the Europeans have been ahead of the curve on passive cooling techniques and the benefits of ventilation which are not just for the structure of the roof but for the health of the occupants too.
This increasing interest in passive ventilation here in Australia is driven not least by the higher energy use and therefore higher energy costs consumers are being hit with. In fact according to Industry.gov.au there will be a 56% increase in residential sector energy consumption over the period from 1990 to 2020. Space cooling is a big part of that growth in usage with forecasts showing it as the fastest growing element over the study period with an average growth of 16% per annum. This is coupled with the penetration of air conditioners in homes which has more than doubled in the past 10 years to about 65%.
With a clear trend for the future new ways of doing things will be needed and with the Rapid Ridge system launching officially at Design Build in 2017 it is an obvious solution to alleviate some of these external pressures on the home owner and the environment. A passive dry ridge ventilated whole roof system that works with the natural space to cool the roof which in turn cools the house – simple! Dry ridge systems have been in use for many years overseas with 100% use now on tile roofs in Germany for instance compared to 0% in Australia where we still have a closed ridge at the highest point of the roof with sand and cement to trap heat in the attic – not smart!
The value proposition to the home owner with the new Rapid ridge system is a saving on energy use by up to 43% in the home and for the builder the value is seen in the install time where it can be done in less than half the time compared to the current traditional method at a similar cost per linear meter. Drop in and see the Rapid Ridge system at Stand A25 and whether you are a home owner or a Builder about to build we can quickly explain the benefits to you.
