Data centers are the fastest-growing building type in Southeast Asia – and one of the most energy-intensive. Operators, investors and hyperscale tenants increasingly ask the same question: can you prove this facility is efficient? Green building certification is becoming the answer, and we are proud to be working on two data center certifications in Thailand right now.

New-build, ~17,000 sqm, Bangkok – TREES Gold (under construction): We support the owner and the EPC contractor from concept design through hand-over: sustainable design charrette, TREES design guideline, energy simulation according to ASHRAE 90.1, daylight and outdoor-air studies, water and stormwater calculations, submittal management with TGBI, construction-phase supervision, material approvals and TREES commissioning of the HVAC, lighting control and electrical systems. Design target: chiller COP > 6.5, full energy and water sub-metering, and a scorecard currently at Gold level.

Five existing data center buildings, ~57,000 sqm, Greater Bangkok – EDGE certification (in operation): Certifying buildings that have run for 1 to 10 years is a different challenge: as-built documentation, 12 months of metered electricity and water data, and PUE (ISO/IEC 30134-2) as the core energy metric. Because the EDGE data center pathway is still a pilot programme, we run the eligibility research and certification strategy directly with IFC/GBCI before the audit – with our in-house EDGE Experts and EDGE Auditors covering the whole process.

Why EGS-plan? Thailand’s first EDGE Preferred Service Provider, LEED, TREES, and DGNB expertise, and 10+ years of German engineering in Bangkok with 150+ projects. Architects, mechanical and electrical engineers and building scientists under one roof – so certification, energy simulation and commissioning come from a single team.

Planning, building or operating a data center in Thailand or the region? Let’s talk about the right certification path for your facility – TREES, EDGE, DGNB or LEED.

We are proud to celebrate the successful EDGE Buildings Certification of Bangkok Marriott Hotels Sukhumvit, a Renovation Project supported by EGS-plan as both EDGE Expert and EDGE Auditor.

As Thailand’s first EDGE Preferred Service Provider, EGS-plan is honored to have contributed to this remarkable sustainability achievement.

Technical Highlights Behind the Savings

⚡ High-Efficiency Chiller Plant
The existing hotel is equipped with 3 centrifugal water-cooled chillers, each achieving a COP of 6.39 at full load, contributing to the project’s energy efficiency and overall energy savings of 37.7%.

💧 Water-Efficient Fixtures

Water savings were achieved through the installation of low-flow aerators, particularly at wash basin faucets. The reduced flow rate helped to cut water consumption by nearly half per fixture compared with the original condition, contributing significantly to the 28.3% water savings achieved under EDGE.

🌍 88% Material Savings – Existing Building Renovation

The project achieved 88.0% material savings (or less embodied carbon) largely because this was an existing building renovation project. By retaining and reusing the existing building structure and major building components rather than constructing a new building from scratch, a significant amount of the embodied carbon associated with new construction was avoided.

Achieving EDGE Certification for an existing hotel undergoing renovation presented unique challenges, requiring close coordination, technical assessment, and careful alignment with EDGE requirements across multiple stakeholders.

Through our EDGE consultancy, technical guidance, coordination, and auditing, EGS-plan helped the project successfully meet its sustainability targets and support the ESG ambitions of Bangkok Marriott Hotel Sukhumvit and Benchasiri Park Property Co., Ltd.

The EDGE Final Certificate was presented by Dr. Robert Himmler, Managing Director of EGS-plan, to Mr. Aditya Shamsher Malla, Multi-Property General Manager of Bangkok Marriott Hotel Sukhumvit and Marriott Executive Apartments Bangkok.

Also joining this special milestone were Mr. Umpon Na Sulong, Director of Engineering, and Mr. Apinant Parnsai, Deputy Managing Director of EGS-plan.

👏 Congratulations to the entire Bangkok Marriott Hotel Sukhumvit team!
We are proud to be part of your sustainability journey and to help turn ESG commitments into measurable results.

We are proud to announce a significant milestone for the SafeBox Bangkok project, a centrally located office building on Banthat Thong Road in Bangkok, which also serves as the office of EGS-Plan. The project has successfully achieved EDGE Advanced Certification.

EGS-Plan acted as the project’s EDGE consultant, providing comprehensive one-stop services as both the EDGE Expert and EDGE Auditor throughout the certification process.

This achievement demonstrates that existing buildings can also pursue EDGE Advanced certification if the project undergoes continuous and strategic development. One of the key highlights of this project is its exceptional 97% Material Saving, attributed to Less Embodied Carbon in Materials. This reflects the project’s strong commitment to minimizing the use of new natural resources through the reuse and optimization of existing materials.

In addition, the project has installed a solar rooftop system with sufficient capacity to support its operational needs, resulting in an impressive 87% Energy Saving under the EDGE criteria. Water efficiency has also been addressed through the installation of water-saving sanitary fixtures, achieving 36% Water Saving.

Furthermore, the project owner has demonstrated strong vision and commitment to sustainability by pursuing an additional certification standard. In addition to EDGE Advanced, the SafeBox Office Bangkok project had previously been awarded Fitwel 1 Star Certification. This accomplishment reflects not only the project’s sustainability performance but also the growing potential for existing buildings to contribute meaningfully to a low-carbon future.

We are proud to announce that PHI SUEA House has successfully achieved  Advanced Certification for an existing building — an important milestone on its journey towards becoming Thailand’s first EDGE Zero Carbon project.

What makes this project truly exceptional is not only its certification, but the innovative energy concept behind it.

Unlike conventional net-zero buildings that remain dependent on the electricity grid, PHI SUEA House demonstrates how a residential development can operate completely off-grid while maintaining a reliable year-round energy supply.

The project’s energy system combines three complementary technologies:
☀️ Photovoltaics generate renewable electricity during the day.
🔋 Battery storage provides short-term energy balancing and covers daily fluctuations.
💧 Hydrogen energy storage acts as seasonal and long-duration storage. Excess solar electricity is used to split water into hydrogen through electrolysis. The hydrogen is safely stored and later converted back into electricity via fuel cells whenever solar generation and battery capacity are insufficient. This unique hybrid concept overcomes one of the biggest challenges of renewable energy systems: providing clean electricity even during extended periods without sunshine.

The installed renewable energy system includes more than 140 kWp of photovoltaic capacity, produces approximately 179 MWh of clean electricity annually, incorporates 192 kWh of lead-acid battery storage, and features a hydrogen storage system capable of supplying approximately 600 kWh of electrical energy via fuel cells. Together, these technologies enable the site to operate independently from the public grid while avoiding operational greenhouse gas emissions.

Beyond operational performance, PHI SUEA House also achieved 100% embodied carbon savings under the EDGE methodology by utilizing environmentally responsible construction materials and sustainable design strategies. Combined with 100% operational energy savings, these achievements resulted in the successful award of EDGE Advanced Certification.

As Thailand’s first EDGE Preferred Service Provider, EGS-plan was honored to support the project as both EDGE Expert and EDGE Auditor throughout the certification process.

Congratulations to the entire PHI SUEA House team on this remarkable achievement. We look forward to supporting the project in reaching its final goal: becoming Thailand’s first EDGE Zero Carbon certified building and demonstrating how renewable energy, long-duration hydrogen storage and sustainable buildings can work together to shape a carbon-neutral future.
