Study Finds Definitive Link between Sustainable Design and Energy Efficiency
Significant effort, capital and time are being invested by
western countries to address climate change impacts by constructing
more sustainable buildings. Building a sustainably designed
dwelling may assist in reducing water and energy consumption
through passive measures, but consumption efficiencies may also be
enhanced or reduced by the behaviour of the occupants within the
dwelling and to date this has not been quantified.
In the paper written by Ben O'Callaghan and Richard Hyde the
method and interim results of research is described and is aimed at
improving our understanding of whether sustainably designed homes
truly achieve lower levels of impact on the environment and also to
what extent occupant attitudes play a role in any improvement.
To carry on this study key utility consumption data has been
measured using real time monitoring systems embedded with the SD
homes at The Ecovillage at Currumbin,
Queensland. Environmental attitude questionnaires have been
used to better understand residents' behaviours. For this
study the primary household resource utilities of energy and water
consumption were studied at two comparable estates, the Ecovillage
and The Observatory Estate, Queensland.
The impact of major variables such as (sustainable) house
design, size of house, hours occupied and the number of occupants
were analysed from consumption data and environmental attitude
questionnaire results.The analysis of the data suggests the
sustainable design of a home contributes significantly to reducing
its energy use. In the case of the Ecovillage (which contains homes
that must meet comprehensive sustainable design criteria) energy
use (on average) was typically 58 per cent less that of the
comparable Observatory estate.
When considering the power generated by homes (most extensively
at the Ecovillage), the ecovillage consumed just 5.7kWh of grid
power per day on average (76per cent lower than the contemporary
estate which consumed energy at rates (23 kWh/hh/pd).
