Delivering Sustainable Development

Green Homes

Objective
Our goal is to recycle 60% of our used building materials, design all new construction to meet green building standards (min GBI) and ensure effective transport services design throughout our new developments.
Progress
We have successfully commercialised our Idea House features into our new township. Roughly 26.2 % of the sustainable features of the Sime Darby Idea House were adopted into Sime Darby Property products. 
Approach
Sime Darby Property’s Idea House was created as a carbon neutral prototype building to model and assess future approaches to sustainable housing. The Idea House was designed to present solutions in architecture, sustainable design and construction efficiency.

The inspiration for the Idea House was drawn from the traditional Malaysian kampong architecture which is known to be functional and highly responsive to the natural environment.

Through the Idea House, we have learned how to decisively respond to design challenges, develop key building systems that minimise waste and enhance quality, effectively manage energy consumption and most importantly create a passive design solution for a comfortable living environment.
Sime Darby Idea House Green Ideas
Landscape
The Idea House is positioned as a pavilion within the landscape, with its curvilinear forms inspired by and blending in with the site’s topographical contours. Both house and landscape are integrated via a landscape scheme divided into garden sections for health, wellbeing, healing, recreation and permaculture.
Orientation, Climatic Responsiveness And Solar Energy
The house is orientated to minimise heat gain and lower cooling loads. Its deep overhangs provide shade and weather protection, reducing reliance on mechanical ventilation, cooling systems and its associated costs. The house uses photovoltaic cell technology to harness the sun’s rays as a renewable energy source.
Building Form
The house is inspired by the traditional Malay Kampong house in its socio-environmental responsiveness, providing opportunities for social interaction in the anjung and serambi verandah spaces. Open, permeable flexible interior spaces with higher roof volumes allow for social and spatial flexibility, made comfortable by cross ventilation.

Water Management
‘Grey water’ from basins and showers are recycled for use in water closet flushing. Rainwater captured by the sloping roof is collected to irrigate the vegetation within the development. Showers are aerated, saving 64 litres of water per day.
Multi-disciplinary Collaboration
The house is the collaborative result by architects, engineers, landscape designers, urbanists, contractors and suppliers with the shared vision to make the Idea House a benchmark in sustainable residential design.
Scalability
The house’s flexibility of modularisation allows us to build larger, higher quality homes at a more affordable price. By using a single component template, the Idea House can be replicated and scaled to other typologies.

Natural Ventilation
The open plan nature of the house, with sliding external and internal walls, capitalises on its ability to be cross ventilated. Orientating the living spaces in a southwesterly direction harnesses the prevailing southwest wind and reduces the need for artificial ventilation. Internal temperature and humidity levels were also lowered.
Expansion And Contraction
The house is a fully adaptable dwelling for the family. It can create more space as the family expands and adjust when the children leave the nest. Open plan living provides a more flexible lifestyle, promoting adaptation of spaces to suit the family’s living, working and recreational needs.
Modularisation And Ease of Construction
Modern construction methods using prefabrication and modularisation means that constructionn is faster, easier and more cost-effective. They allow for structures to be demounted if necessary, to preserve the terrain for future generations and development. They also provide opportunities to employ individuals with a lower skills base.

Topographic Responsiveness
The close interaction between architect, landscape architect, infrastructural and civil engineers led to the ideal positioning of the house within the site. It responds to the contours of the site’s topography, minimising the cutting and filling of the landscape and preserving the site as much as possible for future generations.
Environmental Analysis
The house provides excellent daylight penetration to the habitable areas, reducing the need for artificial lighting during the day and into early evening. Most of the spaces allow for free flow of air with little obstruction. Velocity of air is fairly constant and natural ventilation is effective.

Case Studies
  • Improving Design Efficiency with Building Information Modelling
    Our Property division utilises Building Information Modelling (BIM) in design and development processes to benefit from the greater efficiencies in time, cost, quality and material use that BIM has the potential to provide.
