As the term "Net Zero" becomes a global goal, many may view it as a distant future concern. However, in the heart of Sukhumvit 77, on over 50 rai of land known as T77 Community, that vision is becoming a reality.
Sansiri is not just building residential projects; it is creating a "living ecosystem" that integrates sustainability into the daily routines of people so seamlessly that it is almost indistinguishable. The greatest challenge of ESG in the real estate sector is not merely creating new green projects but rather transforming existing assets to be more sustainable. Thus, Sansiri is using T77 Community to facilitate a significant transition.

The key lies in collaborating with leading partners such as BCPG and ION Energy to transform "limited spaces" into "clean energy sources". By upgrading solar panels for higher efficiency, the results are not just impressive numbers but a testament that efficiency is crucial. Even within the same area, such as Habito Mall, clean energy usage has increased by 328.5%, resulting in over 30% savings on monthly electricity bills.

Imagine a parking lot that is not just a place for vehicles but a "roof that generates electricity," helping to reduce carbon emissions by nearly 50,000 kilograms per month, equivalent to planting 3,300 trees. The community is also connected by an EV Shuttle Bus, eliminating engine noise and emissions, transforming these into cleaner air for residents and children at the international school to breathe easily.

T77 Community consists of a community mall, Siri Campus (Sansiri's headquarters), nine residential projects including condominiums and townhomes, and Bangkok Prep International School. All of these form the largest and most tangible "Green Living Ecosystem" where "environmental care" is a "privilege" for residents, thanks to the innovations that Sansiri is committed to delivering.

The essence of being the most perfect model of a sustainable community is to make "environmental care" synonymous with "living" by harmoniously integrating innovations into the lifestyles of residents, while partnering with leading energy companies to create true sustainability in every square meter through three main strategies:

  1. Significantly enhance solar energy production by collaborating with BCPG Public Company Limited to upgrade solar panel efficiency to a higher standard, allowing for a substantial increase in clean energy production within the same limited space. The results can be seen at Siri Campus, which has increased its electricity production capacity by up to 56%* and at Habito Mall, where the upgraded solar panels have led to a remarkable increase in electricity generation of 328.5%, reducing dependence on grid electricity and achieving long-term sustainable cost savings.
  2. In addition to rooftop installations, Sansiri thinks outside the box, seeking opportunities in every overlooked square meter to create clean energy production without encroaching on usable space. They partnered with ION Energy to transform parking lots into energy production areas by installing solar panels on the roofs of Sansiri's headquarters parking lot, which can generate over 10,832.4 kilowatt-hours of clean energy per month, equivalent to saving over 51,128 THB* in electricity costs. Most importantly, this initiative helps reduce greenhouse gas emissions by 47,750 kilograms of carbon per month.
  3. Driving towards Low-Carbon Transportation, Sansiri aims to make T77 the cleanest air community by fully transitioning the internal transport system to electric energy. This includes the EV Shuttle Bus, which connects the community to the BTS with 100% electric buses, eliminating the use of fossil fuels that contribute to air pollution, particularly the PM 2.5 dust problem, allowing community members to breathe cleaner air. Additionally, EV Infrastructure is being prepared for the future with charging stations distributed across key locations, including Siri Campus, Habito Mall, residential projects, and the international school, to encourage residents and employees to transition to clean energy in their daily lives.

Recently, Siri Campus received the MEA ENERGY AWARDS 2025 certification for promoting energy efficiency improvements in buildings, organized by the Metropolitan Electricity Authority in collaboration with King Mongkut's University of Technology Thonburi. This reflects the success in developing an office building that is energy-efficient while enhancing the quality of life for its users, having passed rigorous evaluation criteria in energy usage, promotion of clean energy, and indoor air quality (IAQ) standards covering key indicators such as CO₂, PM2.5, and volatile organic compounds (TVOC), reinforcing the approach to building development that addresses both "energy savings" and "user well-being".


All of this is a testament to Sansiri's success in taking real action to become a “model of sustainable living.” The achievements from T77 Community will be leveraged in all of Sansiri's future projects, reinforcing that every step of living under the Sansiri brand contributes to creating a truly clean and sustainable world.
