BZE Buildings Plan


 Zero Carbon Australia Buildings Plan - BZE


Phuong Le — Beyond Zero Emissions

Phuong is the research coordinator of the Buildings Plan at BZE, Graduate Architect, tutor and researcher at the University of Melbourne.

Phuong gave a summary of a plan being produced by Beyond Zero Emissions. This plan shows how to reduce the energy and CO2 emission in houses by 50%, and in commercial buildings by 70%.

Replacing all gas with electric:
    heat pump hot water systems,
    reverse cycle air-conditioners,
    induction cooktops;
Stop heat escaping or entering
   Insulating building envelopes – ceilings, walls, and floors
   double glazed windows  
   curtains with pelmets (in temperate climates only)
   draught proofing
Reducing solar heat gain
    windows with low-emissivity coatings and films
    shading using external awnings
    Light coloured roofing
    LED lighting
    Improving energy performance for electrical appliances
    New appliances are now very efficient.    
    Easy to understand displays of energy use
    Rooftop solar photovoltaic and microwind.
Australia has 30 gigawatts of rooftop solar PV capacity. Many buildings could be exporters of electricity.

BZE is a group of research volunteers associated with the Uni. Of Melbourne. They are producing plans to cut CO2 emissions and have already produced their Stationary Energy plan. Their building plan is due out Nov 2012. Future plans are, transport, industry, and land use.

80 Active volunteers – engineers, architects, scientists, data analysts, and others – contributed to the project. Major engineering and design consultancies including GHD, WSP Built Ecology, Team Catalyst, VIPAC, Solem Consulting, Entura, as well as the Facilities Management Association, and a range of companies provided building size, type, and energy data.
