GRESB Certification for Thailand Real Estate: A Practical Guide for 2026
GRESB (Global Real Estate Sustainability Benchmark) has become the standard ESG assessment framework for institutional real estate investors worldwide. For Thai property owners, fund managers, and REITs, understanding what GRESB requires — and how to collect the data — is increasingly critical.
What is GRESB and why does it matter in Thailand?
GRESB assesses the ESG performance of real estate and infrastructure portfolios. Over 2,000 entities participate globally, representing more than USD 8.8 trillion in assets under management. Institutional investors — pension funds, sovereign wealth funds, and insurance companies — use GRESB scores to evaluate and compare portfolios.
In Thailand, ESG-compliant Grade A buildings already command 2 to 8 per cent rental premiums. As international capital increasingly flows into Thai real estate, GRESB participation is shifting from optional to expected.
The two GRESB assessments
For real estate funds, REITs, and property companies. Covers office, retail, residential, industrial, and mixed-use assets.
For infrastructure funds and assets including energy, transport, utilities, and social infrastructure.
KTV Working Drone Thailand is a GRESB member for both Real Estate and Infrastructure, and is listed as a GRESB data solutions partner.
What data does GRESB require?
GRESB assessments cover three broad areas: Management (governance, policies, targets), Performance (energy, water, waste, GHG emissions), and Development (new construction and major renovations).
Electricity and fuel consumption, renewable energy use, energy intensity by asset type
Water consumption, water intensity, recycling and efficiency measures
Waste generated, recycling rates, hazardous waste management
Scope 1, 2, and 3 emissions, emissions intensity, reduction targets
External asset condition data, maintenance compliance, facade and envelope integrity
The external data gap
Most Thai property owners have reasonable coverage of internal metrics — energy bills, water invoices, waste records. The gap is typically in external asset data: facade condition, cleaning compliance, and envelope integrity.
This is where autonomous drone operations fill a critical gap. Every drone cleaning and inspection operation generates verified, timestamped data on external building condition, cleaning compliance, and environmental impact — exactly the evidence GRESB assessors need.
