From concept to construction and throughout the lifecycle of a building, ESi performs comprehensive analyses of the mechanical, electrical, and physical components of building systems to enhance their efficiency, safety, and durability.
Our Building Science team delivers specialized expertise in the performance and reliability of essential building systems like MEP (Mechanical, Electrical, and Plumbing) and HVAC (Heating, Ventilation, and Air Conditioning), with a focus on the structure’s safety, efficiency, and comfort.
We tackle issues in design, operation, and maintenance that can compromise system performance, delivering expert insights to support long-term building integrity and occupant well-being. Our certified and experienced consultants anticipate, identify, and provide recommendations for mitigating existing and potential hazards.
We use specialized testing to assess the materials, performance, and resilience of each system component, ensuring optimal functionality, energy efficiency, and a safer, more comfortable environment for occupants. At ESi, we adhere to the highest industry standards and apply rigorous scientific methods to ensure that our modernization and innovation efforts align with the latest best practices.
We work with our clients to design and restore buildings, develop and implement processes, and provide tailored solutions that enhance safety while preserving the integrity of building systems.
