AOT Office
Building 2
ASO
AOT Academy &
Airport Standards Building
Airports of Thailand Public Company Limited (AOT) is committed to sustainable development by integrating environmental responsibility, energy efficiency, and occupant well-being into its infrastructure development.
As part of this commitment, AOT is developing Office Building 2 and the AOT Academy and Airport & Aviation Standards Office Building at its headquarters. Sustainable design principles have been incorporated throughout the project lifecycle from design and construction to building operations to improve resource efficiency, reduce environmental impacts, and provide healthy, high-performance workplaces.
The project is pursuing LEED Gold Certification, reinforcing AOT’s commitment to developing environmentally responsible infrastructure that supports long-term operational excellence and sustainability.
OUR APPROACH

DESIGN PHASE
Passive & Active Design Designing sustainable buildings through efficient resource utilization.

CONSTRUCTION PHASE
Managing construction waste, wastewater, and pollution in accordance with LEED standards.

OPERATION PHASE
Implement green cleaning & Integrated pest management to protect the environment and promote the health and well-being of building occupants.
LEED : Green Building Assessment Criteria
The project has been developed in accordance with LEED v4 BD+C: New Construction and Major Renovation, the internationally recognized green building rating system developed by the U.S. Green Building Council (USGBC) to evaluate building performance across its lifecycle.
Green Vehicle Infrastructure
Preferred Parking for Green Vehicles
Preferred parking spaces for Green Vehicles and Electric Vehicle (EV) charging stations are provided near the building entrances to promote sustainable transportation and reduce greenhouse gas emissions.

Enhancing Open Space and Biodiversity
HQ2 I ASO
The project is designed to create accessible and functional open spaces that encourage outdoor activities, social interaction, and a stronger connection to nature. Pedestrian pathways, public areas, and landscaped spaces are integrated throughout the site to enhance user well-being while supporting biodiversity and environmental sustainability.

WATER REUSE
COOLING TOWER
WATER MANAGEMENT
The project utilizes native and drought-tolerant plant species together with recycled water for landscape irrigation, achieving a 100% reduction in potable water use for landscape irrigation.
Condensate water recovered from the air-conditioning system is reused as cooling tower make-up water, supplying at least 20% of the system demand while reducing potable water consumption.
The cooling tower system is designed to optimize water use while controlling corrosion, scaling, and microbial growth, improving system performance and long-term operational efficiency.
Improving Energy Performance and Advancing Renewable Energy
RENEWABLE ENERGY PRODUCTION
The project incorporates rooftop solar photovoltaic (PV) systems to generate renewable electricity for on-site use, reducing dependence on conventional energy sources and supporting long-term energy sustainability.

ENERGY PERFORMANCE STRATEGIES
High-performance façade systems, including insulated walls, roofing, and high-performance glazing, minimize heat gain and improve overall energy efficiency.
An energy-efficient HVAC system with an Energy Recovery Wheel (ERW) reduces cooling loads and improves indoor comfort while lowering energy consumption.
Lighting control systems equipped with occupancy sensors, daylight sensors, and programmable scheduling automatically optimize lighting operation to maximize energy savings and occupant comfort.
The lighting control system automatically optimizes lighting operation to maximize energy efficiency while maintaining occupant comfort. The buildings are also capable of recording energy data, enabling AOT to analyze building performance and continuously improve system operation.
HQ2 I ASO
AOT prioritizes construction materials with recycled content and responsibly sourced materials from local suppliers to reduce environmental impacts and support the regional economy.
SOURCE OF RAW MATERIALS
To encourage the use of sustainable products and materials, AOT prioritizes construction materials withover 15% recycled content by value .

ENHANCED INDOOR AIR QUALITY STRATEGIES
To enhance occupant comfort, well-being, and productivity, AOT prioritizes improving indoor air quality through various design and operational measures.
LOW-EMITTING MATERIALS
To reduce the concentration of chemical contaminants that could affect indoor air quality, health, and productivity, AOT implements strict material selection and design strategies.
Dust control mats are installed at all building entrances to minimize the entry of dirt and airborne particles.
High-efficiency air filters (MERV 14) are installed in the fresh air supply system to effectively filter out dust before it enters the building.
Rooms containing hazardous substances, such as chemical storage and housekeeping rooms, are designed as negative-pressure spaces. These rooms feature floor-to-ceiling walls and self-closing doors to prevent the leakage of hazardous substances into surrounding areas.
CO2 sensors are installed in densely occupied areas to monitor and maintain optimal indoor air quality, ensuring a healthier environment for building occupants.
HQ2 I ASO
To enhance the health and well-being of building users and promote community engagement in food production knowledge, AOT integrates sustainable practices into the project design.
Local Food Production
The project features a vegetable garden area, providing building users with the opportunity to participate in planting and learn about the process of growing food for personal consumption.
