Minimalist style is
realism, functionalism, and modern functional style. This style is simpler
residential spaces and furnishings emerged. Nowadays, around the world prefer
to minimalist style. Minimalist style is growing rapidly in Mild Climate and
Continental Climate zone.

This style is
combination between Minimalist, Tropical and Traditional Styles. Minimalist
Architecture becomes one of popular design specially Urban Area.
Limited land in
Urban Area affected in increased Building Material Cost and expensive
construction for housing and becomes the major issues. Minimalist traditional
(Jenki) are transform becomes Minimalist Modern which more simple and reduce
material cost and construction without oblivious to include human comfort.
This
design tends highly consumption energy (fossil fuel) for daily life from Air
Conditioning and lighting. Building sector was responsible for almost half of
all greenhouse gas emissions annually. Waste of mechanical energy for Air
Conditioner and lighting are creating energy crisis and climate change
(emissions of CO2).
Climate change nowadays was the biggest issues of
this century. Architect and building material scientist looking for new method
for reducing the heat flow from the sun to inside the house. One of popular way
is giving exterior layer to wall.

However, Indonesia has blessed with resources of
all kinds. A continuing abundance of forest resources has, since the earliest
settlers, encouraged using wood to build housing. Recycling rubber wood (havea brasiliensis (willd.ex a.juss.) mull. arg.) waste material as exterior layer in
minimalist house in Indonesia to reduce the heat transfer is one of solution.
Why using wood for exterior layer? Why using rubber waste material?
From the early research with Overall Thermal
Transfer Value (OTTV) can prove that the minimalist house whose wall has
covered by hardwood could reduce the thermal resistance up to 3.703 Watt/m2.
In another side, wood’s price is higher than before because of the wood’s
supply in Indonesia become less and less. Rubber wood, one somewhat fast
growing species of hardwood, generally used to plywood because of it mechanical
properties as same as Teak wood.

However, their wastes are used to firewood.
Using wood wastes of Rubber wood as a wall cover (exterior) could proves that
the minimalist house design, adapted from aboard, has become energy efficient
house that can reduce the climate change’s effects.
