Title: ENVIRONMENTALLY RESTORATIVE ARCHITECTURE
1ENVIRONMENTALLY RESTORATIVE ARCHITECTURE OR ARCH
ITECTURE IS A DYING PROFESSION Source
Paul Hawken
2GREENHOUSE GASES NZ
- In the 1990s in NZ, CO2 produced for energy use
increased by 22. - Contrary to our Clean, Green image, if the
entire world lived like New Zealand we would need
4 planets to sustain human life. - Yet NZ has been ranked No 1 in the world terms
of its environmental performance by the Pilot
2006 Environmental Performance Index (EPI).
3MATERIALS
- 40 of the 7.5 billion tons of raw materials
annually extracted from the earth is used by the
building industry. - The rate of timber deforestation has almost
doubled in the past 10 years. - 25 of all timber harvested each year is used for
construction. - Buildings consume 40 of the worlds energy
consumption and produce 40 of the sulphur
dioxide and nitrogen dioxide that causes smog and
acid rain
4WASTE
- New Zealand currently land fills sufficient waste
to fill the Westpac Stadium 3 times over per
year. - New Zealand has signed the Kyoto Protocol but we
have yet to meet any of the targets set including
waste reduction. - As long as we regard waste as being taken away
we will not solve this issue. In nature Waste
Food and we need to embrace that thinking.
5POPULATION
- In 1900, there were approximately 0.5 billion
people on this planet. - In 2006, there are approximately 6 billion people
on this planet. That is a 12-fold increase. - 1 billion of those use approximately 80 of the
worlds energy - It is estimated we will build more buildings in
the next 50 years than we have in last 500 years.
6CLIMATE CHANGE
- Climate change is not a threat, but a
scientifically agreed reality. - The damage done to date may take hundreds of
years to repair. - Ignoring our impact on the environment will not
make the issue go away. - Climate change will be the first natural disaster
which man-kind knew was coming.
7IN SHORT, OUR IMPACT ON THE PLANET IS NOW FAR
GREATER THAN AT ANY TIME IN HISTORY
POPULATION
8ENERGY EFFICIENT
- Low energy design strategies are normally
assessed by their payback period i.e. the length
of time it takes to pay back the cost of the low
energy design - computer energy modelling allows payback periods
to be estimated with reasonable accuracy - Today mechanical engineers can thermally model
the design of a building
ENVIRONMENT CANTERBURY HQ
Our present age of information and ecology
suggests an architecture of less substance and
more information, less exclusion and more
inclusion, less objectification and more
fragmentation, less Euro-centrism and more
cultural diversity. Source James Wine

OWNER
11HEALTHY BUILDINGS
- High levels of natural ventilation to improve
internal air quality - High levels of day lighting throughout the plan
- Good user controls to allow users control over
their environment - Low toxicity materials to improve indoor air
quality
GLEN EDEN LIBRARY
12MATERIAL SELECTION
- Specify sustainable sourced timber (via FSC)
- Avoid the use of environmentally damaging
materials PVC etc - Support the NZ Environmental Choice labelling
scheme - Use durable materials and minimise paint finishes
- Note companies that are making an effort i.e.
Interface, Resene - Use locally manufactured products
- Use recycled materials or materials with recycled
content
ALFRISTON COLLEGE
13WASTE MINIMISATION
- Waste Food
- Design using 100 recycled products e.g. carpets,
fabrics, insulation, concrete - Provide space for waste separation, waste
recycling, waste storage - Waste mining
RICCARTON LIBRARY
14WATER USE
- Low water use plumbing fittings
- Low water use equipment
- Rainwater collection and reuse
- Solar water heating
- Disconnection from potable water supply for all
non-drinkable water. - Water as a coolant and heat sump
- Water filtered and treated on site prior to
discharge into public stormwater system
SOUTH CHRISTCHURCH LIBRARY
15SITE ECOLOGY
- Maximise biodiversity
- Retain valuable existing landscape and mature
vegetation - Use of local indigenous planting
- Stormwater management reducing erosion, flooding
and loss of habitats - Filter all stormwater on site for re-use within
the buildings and landscape - Maximise site location / orientation to reduce
energy use

16SOCIETY
- The act of building as practiced at present is
the ultimate violent act, producing vast amounts
of toxins, waste and on-going damage to the
environment. - Buildings should be sources of pride, of joy,
rejuvenating the social and built fabric not just
for humans but for the environment and the future
generations to come. - Life is right, and the architect is wrong.
- Architects and the building professions can
change and be a source of inspiration in this Age
of Ecology.
Virtually no form of shelter constructed today
can be credited as authentically green.
Everything that technologically dependent
societies assume is essential for survival as
plugged into the same diminishing sources or
power. James Wines
17WHAT ARE THE BENEFITS OF SUSTAINABLE DESIGN?
- The benefits of sustainable design
strategies can be categorised into three groups - Future proofing
- Durability and flexibility
- Future energy targets
- Future health demand
- Political / marketing
- Bragging rights
- Brand loyalty
- Financial
- Running costs financially small,
environmentally huge - Staff costs financially huge savings
18WHAT DOES SUSTAINABLE BUILDING MEAN FOR THE
FUTURE?
- New ways of thinking about how buildings operate
and are designed. A whole new series of design
opportunities - New buildings which have a beneficial / positive
effect on the environment. - This is
19AN ARCHITECTURE which is
- 100 self sufficient in power- in fact producing
energy. - 100 self sufficient in hot water supply
- 100 self sufficient in potable water in fact
producing more water than it needs - 100 free of toxins, VOCs and other irritants.
- Naturally lit, non air-conditioned
- All materials 100 demountable and recyclable.

21WHY?
After 11,000 years if building to protect
ourselves from the environment, the delicate
environment must now be protected from us. -

22Source Mum and Dad
WHY?
- We have no choice
- We want to create a viable future for the next
generations - It is a win-win scenario
- It will lead to wealthier and healthier
communities and environments - What will you tell your grandchildren you did at
the beginning of the 21st Century?
23HOW?
Changing the mindset

24THE RESULT
Buildings as nett generators of energy,
manufactured from waste materials and which
improve the environment around them We call it a
new ERA Environmentally Restorative
Architecture
