The Ecoloft serviced apartments are situated in Cikarang (Bekasi), which is becoming the new industrial hub in the greater Jakarta area. The townhouses are in the heart of the Jababaka Golf Course, surrounded by trees, lakes and walking paths, offering a great recreational setting while only being minutes away from the bustling business center. The apartments are resource-efficient and environmentally friendly, from layout and design straight through to construction, operation and maintenance. Residents are estimated to benefit from energy savings of more than 80 percent primarily due to the installation of solar technologies.
Ecoloft Jababeka Cikarang, which has been developed by Asia Green Real Estate, has received final EDGE certification from the Green Building Council Indonesia.

Owner approach of sustainability
Progress: Ecoloft changes the paradigme of typical townhouse in Indonesia, though its a standardised and repeatable unit. The structure leaves plenty of flexibility to merge two units with larger floor area, even become standalone buildings. Conventional townhouses' small garden at the Ground Floor is moved in Ecoloft concept on the roof while using GF as ventilation/parking area. All construction details are state of the art and adjusted to tropical context of Indonesia.
People: The building provides high comfort levels to occupants by using thermal mass at the inside and insulating the structure consequently from the outside. Interior cooling is laid out as hybrid system; the openable double glassed windows are equipped with flexible sun shading and the interior air is conditioned and moved by high-efficient ACs and Heiku fans which leaves the choice to the occupant for natural ventilation or enforced conditioning. Water taps are 100% potable in every unit.
Planet: The team has taken high attention to a small building footprint, minimised earthwork to be optimised for land use. Materials are 95% locally sourced, energy efficiency is maximised with sunshades, thermal insolation and double glassed windows, stilt-house design and green surroundings harvest the natural ventilation and evaporative cooling. Low energy hybrid cooling technologies are selected to minimise energy consumption, as well as the solar water heater reduces power consumption from the grid. Additionally, renewable energy is produced by the PVs on the roof. The harvested rainwater is reused efficiently for toilets/ garden and permeable surfaces allowing water to percolate back to the ground. Local plants on the facades help to shade the roof garden.
Prosperity: The project was financed by a mandatory convertible bond making it attractive for longterm investors who will hold shares of the property firm once construction is completed. The project serves the the rental market with expected yields over 10% p.a.
Proficiency: Overall, the typology is the modern interpretation of traditional Indonesian stilt house. The dense land use leading to highly efficient building massing, yet privacy is carefully preserved for all the units by placing openings selectively and the use of fins for view protection. The inside is determined by airy and natural light flooded spaces, vertically flowing room continuum over 2 floors. The open floor-plan allows crossventilation and attractive interior views.
The Ecoloft Jababeka Golf Apartments are built on a total land area of 2000 m2. The townhouses accomodate 19 apartments with great views across the golf course. With 96m2 gross floor area, 26m2 shaded roof terrace and 33m2 covered private parking area, the units have a spacious but cozy footprint. Each townhouse is a truly eco-efficient construction and green building.
The elevated site has an east-west aspect over the longest perimeter. Drive-in access is from the north end, connecting to both the rest of the estate and the golf course, which is just 3 minutes away.
The development has a single internal green lane of water-permeable hard standing, designed to allow rain infiltration, one of the most effective means to control tropical downpours – dispersing the water instantly. Deep wells supply the entire complex with water via a filtration system.
