Energy Audit

We do building energy audit to identify mechanical equipment and systems energy consumption, and determine the energy performance compared to other buildings. We will find out the energy losses,  deficient equipment and what to do to save energy use and reduce utility bills. ESO-Tech provides ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) Level 1, 2 and 3 energy audits for commercial buildings and industrial facilities.


Retro-commissioning is a process to improve the efficiency of an existing building’s equipment and systems. ESO-Tech can resolve problems that occurred during design or construction, and address problems that have developed throughout the building’s life as equipment has aged, or as building usage has changed. Retro-commissioning involves a systemic evaluation of opportunities to improve energy-using systems including lighting, HVAC, heating/cooling plant and controls etc.

Energy & Sustainability

We utilize the integrated design approach to analyze the energy and sustainability performance from very early phase of projects in order to find the best solutions for our clients. ESO-Tech provides cost-effective and innovative solutions that can help us to achieve energy efficiency and low carbon footprint in future. Areas of our practice include:

  • Master energy planning and sustainability design
  • Whole building energy modeling
  • Life cycle cost analysis
  • Incentive program applications
