Our Environment
“For us, the challenge to build visionary developments is how to contribute positively to the environment and society. Local wisdom is very important in development. Compliance to regulation is a must-do, however, we strive to go beyond just compliance”
Key Environmental Activities
Environmental responsibility is closely related to the Company’s business processes. Intiland develops projects that always prioritize environmentally-friendly and energy-saving elements. This commitment was reflected in the early construction stage of the Intiland Tower building in 1984, at a time when the wider community had not paid adequate attention to environmental issues and green building design.
Fundraising initiative and concervation talks
Intiland establishes sustainability journey to ensure the evolving process will take place effectively and efficiently in the long run. It starts with compliance and risk management steps. For us, this step is very important to set strong foothold upon achieving the long-term goals which are to increase the values of Intiland for our stakeholders.
As mentioned before in out sustainability report boundaries, this first sustainability report focuses on our operations in three office towers in South Quarter, an integrated mixed-use development which is located in TB Simatupang, South Jakarta, particularly for environmental issues.
28% Energy Savings
South Quarter is equipped with a set of energy savings features to reduce building energy consumption. South Quarter uses reflective light color paint for its roof and external walls as well as polyurethane foam insulation to reduce the heat gain from the sun. In addition, fixed external shading devices are installed to prevent excess sunlight into the building. South Quarter is already 28% more efficient in energy usage compared to other buildings in Jakarta, Indonesia.
Total energy consumption in 2020 decreased from 18 million kWh in 2019 to 16.2 million kWh in 2020 because most of the tenants implemented social restrictions to limit their employees due to pandemic situation. The energy intensity by GFA Occupied also decreased by 19%, which is still lower than Energy Consumption Index or ‘Indeks Konsumsi Energi’ (“IKE”) standard stipulated by the Governor of the Capital Region of Jakarta No.38, 2012.
The management has undertaken other initiatives to improve the energy efficiency such as conducting energy audit and setting the target for efficiency and action plans. The management also launched energy efficiency campaigns encouraging tenants to turn off lights in vacant rooms, use natural lightings for rooms with windows, use stairs instead of lifts for reachable floors and use of energy-efficient LED light bulbs. Separation of the electricity meter has been done for air management system, light management system and other electricity loads to closely monitor the energy usage.
81% Water Savings
By building structure and system, water savings in South Quarter is already 81% more efficient compared to average buildings in Jakarta, Indonesia. High-efficient water fixtures are installed in the building such as bathroom/kitchen faucets, urinal, and dual-flush closets. An integrated water management system is utilized to help reducing wastewater and stormwater runoff.
Rainwater is collected from the rooftop and stored in a tank before it is treated and reused. Grey and black water from toilets will be treated and reused for cooling tower makeup water, toilet flushing, and irrigation. By adopting comprehensive rainwater and grey/black water recycling systems,high-efficiency water-saving fixtures, South Quarter is expected to consume 217,141 m3/year more less.
The management is committed to a more efficient water consumption by installing flow restrictor on the water faucets, separating water meter for public, commercial and building utility areas, and conducting monthly audit for water usage.
Embodied Energy Material
South Quarter Tower C (SQC) has lower embodied energy compared to the base case of buildings in Jakarta, Indonesia. Its floor slab has 54% lower embodied energy than average buildings, while its external wall has 42% embodied energy reduction. However, the aluminum windows frame has higher embodied energy of material by 36% compared to the local buildings.
Overall, SQA’s embodied energy savings of material is 32.01% and it meets EDGE minimum materials requirement. The savings of Embodied Energy of Materials from the EDGE calculation for SQA, SQB and SQC are approximately 86,105 GigaJoule compared to the local buildings.
