Building and living responsibly in the city
19/06/2005 Sunday Times
IT may be a pipe-dream, but if an architect has his way, we would all be living
in a sustainable way, writes ELIZABETH JOHN.DO you like the home in which
you live? Are you satisfied with the design of your neighbourhood, the level
of noise, pollution, transport and availability of green space?
Architect John Koh isn't and he believes that many Malaysians aren't either.
Our homes, neighbourhoods, the city and the environment we live in are simply
not happy or sustainable places, says Koh, the immediate past president of the
Eastern Regional Organisation of Housing and Planning, and now the managing
director of Aktitek Maju Bina Sdn Bhd.
A sustainable building is a structure that is designed, built, renovated,
operated or reused in a resource - efficient manner; in a way that will not
compromise the health of the environment or the well-being of the building's
occupants, construction workers, the general public or future generations, explains
Koh.
What we have now doesn't quite fit that bill.
"The ordinary Malaysian will tell you that he is confronted by so many unresolved
sustainability issues.
"These range from non-availability of cheap and safe drinking water, increasing
cost of energy and the lack of affordable homes to growing problems of pollution,
environmental degradation in our neighbourhoods and security concerns in the
suburbs and cities," says Koh.
Malaysians cannot help but admit that they have lost a fair measure of themselves,
the beautiful countryside, mountains and rivers and oceans, he laments.
"We've lost our pristine air, clear skies, predictable rain, our beautiful
heritage structures and the memories of our youth," adds the architect who is
also a member of the Board of Trustees of Malaysian Nature Society.
His feelings were shared by many in the audience at the National Conference
on Sustainability Malaysia 2005, where Koh recently spoke on the need for sustainable
housing.
Engineers, educators, planners and policy-makers stood up at the end of the
session to talk about the good old days and how neighbourhoods were so much
better back then.
An architect since 1973, Koh has witnessed the transformation and understands
their sentiments.
The audience nodded in agreement when Koh spoke on unsustainable planning
issues like inadequate structure plans with little follow-up in local plans
and weak environmental impact assessments.
He pointed to the suburban sprawls, urban slums and traffic snarls in towns
and cities that cause the one-way street solution to become a feature of so
many Malaysian towns today.
Other examples raised provoked more vigorous nods and wry smiles.
These included highways cutting through townships, said Koh, citing the example
of the Lebuhraya Damansara-Puchong.
He also has a bone to pick regarding the levelling of mountains and clearing
of forests for development such as those in Puncak Perdana in Section U10 Shah
Alam and Damansara Damai in Sungai Buloh.
"For some inexplicable reason, we cannot stand to see peaks. We just love
to lop it off and put lowland structures on top."
Unfortunate forages into sensitive environmental areas in Selangor, encroachment
into wetlands along the peninsula's west coast and into the high water line
at coastal resorts like Port Dickson are other worrying trends that Koh noted.
He is also disturbed by inadequate development planning and enforcement of
safety and health guidelines, as well as the unbridled development of golf courses
for the few at the expense of public recreational parks and affordable housing
needed by many.
"We even see residential projects built right next to high tension power
cables!" said an incredulous Koh. However, the blame does not rest entirely
with the authorities, he says.
"In a lot of ways the public is to be blamed. They do not seem to be aware
of what they are buying. They seem almost mindless."
With the situation so dire, is there any hope left? Koh thinks the situation
is redeemable.
A well-thought-out brief and proper site selection are the first prerequisites
to sustainable design, says Koh.
For the hot and wet tropical weather we experience, a building's orientation
towards the sun and wind is important. Designing to contours in sensitive hillside
development is also necessary as are the use of local materials and techniques.
"Obsessive imitation of Balinese architecture and the ensuing demand for
river stones, sea sand and cut corals from Indonesia and the Philippines has
devastated the environment in those countries.
"Figures show that the activity of building consumes an estimated one-sixth
of the world's fresh water withdrawal, a quarter of its harvest and two-fifths
of its materials and energy flow.
"This fact makes it all the more imperative that we design and build in a
sustainable way," he says.
Retaining existing mature trees outside the development footprint, reusing
excavated boulders and landscaping to serve as shade and noise or dust filters
are simple steps that make a neighbourhood a nicer place to live.
Much could also be done to conserve energy and resources, adds Koh.
Proper solar and wind orientation, adequate roof cover, screens and openings
for thermal comfort are the first line and best energy conservation approaches.
Tapping natural cross ventilation will reduce the need for air-conditioning
while harvesting rain water for toilets and watering the garden could reduce
the demand for expensive treated water. They don't need complicated technology
to effect.
While sustainable habitats may be a tall order, they are achievable, argues
Koh.
We could begin by adopting the 4Rs of sustainable building.
* Reduce, Koh has urged planners and developers - in other words, rethink
the 22x75ft terrace lot subdivision approach.Instead, go high in urban sites
to free up land for recreation and conservation, design compact units but not
new slums, and select durable materials for longer service life and easier maintenance.
* Reuse, he says. Materials like bricks, roof tiles, timber, windows and doors
left over from a renovation project can often be reused. And heritage buildings
could be adapted for re-use as the Central Market building in Kuala Lumpur has
been.
* Renew, the concept of which proposes the greater use of natural energy sources
like wind, sunlight and water to minimise the impact of a building on the environment
and reduce those hefty electricity bills. Koh recommends working with the Japanese
who have come up with remarkably affordable solar systems for space cooling.
* Finally, recycle, recycle and recycle. Examples abound all over the world.
Recycled cardboards and sandbags have been used to create award-winning refugee
shelters or temporary housing in disaster zones, for example. Koh wants to see
the introduction of a five-star home sustainability index - a rating based on
quality and comfort; affordability; environmental soundness and impact on local
economy; water and energy-efficiency; and reduction of energy bills. The system
is already in use in Australia.
With so many tried and tested laws and guidelines around the world to
tap, it's a matter of a little thought, good planning and strict enforcement
that the ideals of sustainable housing would be achieved, Koh believes.
There is a need to reform the local authority structure and ensure follow-up
to local and structure plans, Koh adds. We also must uphold strong ethical standards
and think and act holistically when building homes and cities.
For instance, he would like to see an end to indiscriminate redevelopment
of historical sites as in Malacca and a greater monitoring of housing contractors
- the people who would be responsible for bringing these ideals to life.
Despite the crucial role contractors play in creating living spaces, there
is little policing of their work, he says.
We are at a crossroads.
If we want the kind of living spaces we speak of nostalgically, the homes
of the good-old days, planners have to return to the drawing board with a new
vision and we the buyers, must learn to be reasonable in our demands.
