This guide offers practical advice to homeowners, builders and designers embarking on a retrofit of an existing home. It focuses on relatively simple adaptations to improve a home’s comfort, while reducing energy bills and carbon emissions.
The implementation of ‘cool’ roofing materials, with high solar reflectance and infrared emittance, has received significant attention in recent years, as a method to mitigate the urban heat island effect and reduce building cooling energy requirements. The effect of ‘cool’ roofs on heat transfer through the roof structure has been investigated by many researchers.
Conventionally in building performance simulations (BPS), it is assumed that air entering outdoor HVAC equipment is at the outdoor ‘ambient’ temperature, obtained from a weather file. However, significant spatial variations exist in outdoor air temperature fields, especially within the thermal boundary layers that form near exposed surfaces like roofs.
A rapid systematic review of international academic literature suggests that home buyers typically value a more energy efficient home, and when presented with easily accessible information in the form of an energy performance rating, are willing to pay more to live in one.
This Guide to Implementing Low Carbon Retrofits for Social Housing is intended as a simple to use reference for social housing asset managers and others involved in social housing upgrades. The guide presents a concise summary of effective energy efficiency optionsfor social housing properties, including:
This is the first interim report for project RP1037u1, an extension to the recently completed project RP1037 ‘Driving increased utilisation of cool roofs on large footprint buildings’. Progress so-far in the project and preliminary findings have been summarised in this report.
The buildings sector is responsible for approximately 23% of Australia’s carbon emissions. The Australian Sustainable Built Environment Council (ASBEC), the peak body for sustainability in the built environment, has identified that improving the minimum standards for energy efficiency of new buildings can assist in delivering carbon emissions reductions.
