Energy Strategy

Residential

Our 3-pillar energy strategy for residential developments spans the entire lifecycle from design and construction to occupancy. By integrating passive design, energy-efficient technologies, and renewable energy solutions, we aim to reduce energy demand and enable low-carbon living.

Design Stage	Construction Stage	Occupancy Stage
Strategic Interventions
Project office, sales gallery, and residential homes Demand reduction through climate-responsive design (CRD) CRD includes passive design measures such as avoid, orient, shade, reflect Passive design strategies are incorporated to achieve comfortable internal temperatures through appropriate use of walling and roofing materials and efficient, shaded, and right-sized windows to reduce solar heat gain For optimal lighting, an effective wall-window ratio is used Energy-efficient equipments Design for energy-efficient lighting requirements Design for usage of solar lights, water heating systems Design for use of energy-efficient water pumps, motors, lifts Integration of renewable energy Design for use of on-site (rooftop) solar, wind, etc. Tie-up with a 3rd party renewable energy distributor to meet remaining energy requirements for residential homes and common areas. Plotted developments (common areas within them developed by us) Energy-efficient equipments Use of LED lights and solar streetlights in common areas Design for use of energy-efficient water pumps, motors, lifts	Project office, sales gallery Energy sensitisation — posters, training, etc. (behavioural interventions) Metering for office and contractor electricity usage — Ohm assistant meters by Sustlabs installed across offices Use of energy-efficient equipment — star-rated ACs, refrigerators, fans, lights, etc Process improvements — through the sustainability maturity assessment framework	Residential homes Energy sensitisation (behavioural interventions) - through resident assistance, sustainability flipbook, and capacity-building workshops (Make the Switch). Use of energy-efficient equipment — star-rated ACs, refrigerators, fans, lights, etc. Use of on-site renewable energy for 100% common area lighting Use of grid-based renewable energy from a 3rd party for powering remaining energy requirements for residential homes and common area

IC & IC

Our 3-pillar energy strategy for IC & IC focuses on demand reduction through climate-responsive design, energy-efficient operations, and integration of renewable energy sources. These measures are embedded across the development and O&M stages, enabling resource efficiency and decarbonisation at scale.

Renewable Energy

After minimising energy demand through climate-responsive design and use of energy-efficient systems, we turn to cleaner sources of energy. Our focus on renewables has shown results. We are increasingly integrating renewable energy solutions during the construction phase within our residential projects to reduce our carbon footprint. Apart from on-site RE, we also initiated procuring renewable energy from the grid at our residential project, resulting in operational cost savings, underscoring both environmental and economic benefits.
