|
Fear of seeming radical |
|
|
|
|
|
|
Why Bother when so Hard? |
|
|
|
Massive, cost-effective improvements possible
(maybe not where you first think) |
|
Challenging/fun |
|
Someone needs to throw spanner into linear,
stone tablet, Chinese whisper process……. |
|
|
|
|
|
|
Why Bother? (cont.) |
|
|
|

|
|
Annual Energy Budget for 60L : |
|
|
|
Expected energy savings over 65 % per year
compared with a conventional office building. |
|
Electrical energy for lighting will be reduced
by over 80%, and for equipment and ventilation, heating & cooling by
over 60%. |
|
Zero fossil fuel-based supply |
|
|
|
|
|
Annual CO2 Emissions for 60L |
|
|
|
Use of
electricity derived from premium non-fossil fuel sources (Green Power) will
enable savings approaching 100 % in annual carbon dioxide emissions,
supplemented by offsite carbon sequestration (even considered offsite
renewable generation) |
|
|
|
|
Annual Water Consumption: |
|
Over 500 kilolitres of rainwater collected in an
average rainfall year for use by taps and showers. |
|
Water efficient fixtures and toilets reduce
water consumption by over 60%. |
|
All wastewater and sewage treated organically on
site and then recycled for toilet flushing and irrigation of the roof
garden. |
|
Total savings in average annual mains water
consumption of over 90% (fire testing) |
|
|
|
|
|
|
|
The 60L competitive advantage : |
|
occupants have some control over their thermal
environment (neighbourliness). |
|
enabling occupants to reduce demand for energy
and water services |
|
enabling occupants to behave in an ecologically
responsible manner. |
|
a pleasant and healthy working environment |
|
significant enhancement of occupant productivity |
|
|
|
|
|
|
Occupant health, comfort and productivity is
achieved through |
|
openable windows |
|
glare-free daylighting |
|
significantly improved internal air quality |
|
materials selected to avoid unwanted volatile
chemical compounds |
|
a landscaped roof garden |
|
occupant control over thermal comfort |
|
|

development area |
|
|
|
|
|
|
|
Quality environmental management through |
|
|
|
Leases |
|
environmental management systems |
|
user involvement in building operation |
|
creation of a building community |
|
on-line display of building performance |
|
monitoring and fine-tuning of post occupancy
environmental performance. |
|
|
|
|
|
|
Aims of the MCC strategy – |
|
“Environmentally Responsible City” : |
|
|
|
Reduce greenhouse gas emissions |
|
Encourage efficiencies in resource use and reuse |
|
Protect and enhance the City’s biodiversity |
|
improved environmental sustainability of
Council’s policies, services and operations. |
|
|
|
|
|
|
The Regulatory Framework should: |
|
Require the implementation of wholistic ESB
design |
|
Apply to commercial & industrial
developments |
|
Require post-occupancy performance monitoring |
|
Provide protection for existing or approved
buildings with sustainability elements |
|
Prevent overshadowing of solar collection
devices and roof space on adjoining properties |
|
Minimise impacts on passive solar elements of
adjoining buildings |
|
Require building environmental management plans |
|
Set far less wimpish and broader minimum
environmental performance standards |
|
|
|
|
|
|
Take home messages |
|
|
|
Take a wholistic approach to building design,
construction and occupation |
|
Occupant behaviour is as important as bricks
& mortar (given a chance) |
|
Significantly more environmentally sustainable
design of buildings is commercially viable. |
|
ESB principles should be incorporated into the
regulatory and planning systems. ….. |
|
|
|
|
|
|
….Take home messages |
|
|
|
Immediate and life cycle environmental and
financial dividends are available from– energy & water savings AND
occupant productivity |
|
60L provides a raft of demonstrations towards
achieving the triple bottom line in the built environment sector …. And, to
penultimate on something far more important…. |
