BedZED monitoring data
BedZED was designed to minimise its ecological impact both in construction
and operation - to help residents live within their fair share of
the world’s resources. Some of the key operational aims were
as follows:
• reduce water consumption by 33%
• reduce power consumption by 60%
• reducing space heating needs by 90%
• reduce private fossil fuel car mileage to 50% of UK average
• eliminate carbon emissions due to energy consumption.
Monitoring
progress towards achieving these targets is vital in order to assess
the effectiveness of the project, identify areas for further improvement
and highlight lessons that can be learnt and applied to future developments.
The main aim of the monitoring strategy is to ensure that robust,
consistent information is collected allowing us to calculate the
ecological footprint of the BedZED community.
First monitoring results at the end of
October 2003
Monitoring results from the BedZED's first year of occupation show
that building performance and transport patterns have been very
much as expected.
Table 1 shows comparisons with the national average for space heating
and hot water, with new homes built to year 2000 Building regulations
in brackets.
Costs and savings
Table 2 shows costs and savings for a 6-plot BedZED terrace combining
six 3-bedroom maisonettes, six 1 bedroom flats and six live/work
units, and are compared to a conventional development with a similar
floor area.
These figures include 100% renewable electricity supply, 100% waste
water recycling and a full green transport plan.
Predicted sales premiums for future ZED
developments.
The market
for sustainable housing has been clearly demonstrated at BedZED.
FPD Savills have showed that buyers are willing to pay up to a 20%
premium for innovative design and 'green' features such as those
at BedZED. See Table 3 below.

Monitoring 2007
This monitoring
is now complete and the full report is available as a free extra
for anyone buying the BedZED
toolkit parts 1 or 2.
It covers energy and water consumption in BedZED homes and offices.
And the results of resident interviews re. transport, food and waste
habits, and measures the extent to which the green
lifestyles strategies have reduced ecological footprints.
