What is TREES Standard?<\/h2><\/div>

In 2009, the Association of Siamese Architects and the Engineering Institute of Thailand jointly established the Thai Green Building Institute to initiate and promote the development of green buildings for environmental sustainability among building owners.<\/p>\n<\/div>

Types of TREES Green Building Certifications<\/h2><\/div>

1. TREES-NC\/CS (New Construction and Major Renovation \/ Core and Shell Building) Assessment criteria for new construction, major renovations, and core and shell buildings<\/p>\n

2. TREES-EB (Existing Building Operation and Maintenance) Assessment criteria for buildings during operation<\/p>\n<\/div>

How does TREES evaluate buildings?<\/h2><\/div>

Green building assessment according to TREES standards has a total of 100 points, divided into 8 categories as follows:<\/p>\n
