Designed for Sime Darby Property, the Idea House is South East Asia’s first carbon zero residence. The Idea House has prefabricated modules that save up the construction cost and speed up the process at the same time. The modules also allow easy deconstruction at the end of the house’s useful life.Aside from being pre-fabricated, the Idea House also has some other green features including the deep overhans that are responsible of providing shade. The house also has open and flexible interior spaces for various purposes. Greywater system is also available for water recycling purposes. The green roof garden has rainwater capture system that can be used for irrigation. The photovoltaic system located on the rooftop provides power to the entire house and its optimal site orientation increases ventilation and lighting during daytime. If the Idea House will come into fruition, it will definitely reduce harm to the environment of all over South East Asia.
