On 26 June 2026, Mr. Sarut Wanamkang, Head of Engineering at EGS-plan, conducted a technical seminar entitled “ASHRAE Standards for Green Building Consultants”, introducing key ASHRAE standards and their application in high-performance buildings and green building certification systems.

Hosted at the office of our long year certification partner Africus, the seminar provided an overview of the most relevant ASHRAE standards for green building projects, with a particular focus on building commissioning as both a fundamental prerequisite and an effective strategy for achieving additional credits under certification systems such as LEED and TREES.

Key topics covered:

📖 Introduction to ASHRAE standards for green buildings.

📖 Application of ASHRAE 90.1, ASHRAE 62.1, ASHRAE 170, and ASHRAE 55 in sustainable building design.

📖 The role of building commissioning in achieving LEED and TREES certification.

📖 Practical approaches to improving energy efficiency and overall building performance.

Beyond the technical content, the seminar further strengthened the partnership between EGS-plan and Africus, creating valuable opportunities for collaboration, knowledge exchange, and professional development.

We sincerely thank the Africus team for their warm hospitality and active participation. We look forward to continuing our successful collaboration and contributing together to the advancement of high-performance green buildings.

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.
