Sustainability
Driving Towards TREES-CS Version 1.1 Certification
18 Jun 2026

Summer Lasalle Campus C Phase 1



Summer Lasalle Campus C Phase 1 is dedicated to developing its buildings and surrounding spaces with sustainability at the core. Our goal is to create a high-quality work environment that promotes occupant well-being while minimizing long-term environmental impact. The project is currently pursuing TREES-CS Version 1.1 certification, one of Thailand’s leading green building standards.



TREES-CS (Thailand Rating of Energy and Environmental Sustainability – Core and Shell Building) evaluates energy and environmental sustainability specifically for core and shell developments. It focuses on energy efficiency, responsible resource use, effective environmental management, and improving the overall quality of life for building occupants.

Aligning with the TREES-CS framework reflects the commitment of Summer Lasalle Campus C Phase 1 to build workspaces that go beyond business needs. We aim to balance economic growth, social responsibility, and environmental stewardship to deliver long-term value for our tenants, occupants, and the surrounding community.



Our Approach to Sustainability



The project focuses on efficient space design and management to optimize resource use, reduce energy consumption, and support a healthy environment for everyone on site.



  • Green Spaces & Connectivity: The landscaped areas are designed as open, green spaces for relaxation, outdoor activities, and social interaction, offering a refreshing, natural atmosphere that enhances daily work life.



  • Daylighting: The building maximizes natural light in occupied spaces, reducing the need for artificial lighting during the day while improving visual comfort and boosting productivity.



  • Indoor Environmental Quality: We prioritize indoor air quality by selecting Low-VOC (Volatile Organic Compound) materials, ensuring a healthier and safer indoor environment for all users.

Committed to a Sustainable Future



At Summer Lasalle Campus C Phase 1, we believe that great buildings should do more than just provide functional space—they should uplift people's well-being, use resources responsibly, and continuously reduce environmental impact.

Pursuing the TREES-CS Version 1.1 certification is a major milestone in raising our development standards. It reflects our vision to create modern, high-quality workspaces that grow sustainably alongside our community.
