Mr. Eliason has a background in building enclosure systems design, evaluation, forensics and repair as well as mechanical HVAC systems design and evaluation. He regularly provides design peer reviews for building enclosure and mechanical systems, failure analysis of building envelope systems, destructive and non-destructive testing services, quality assurance site observations, building commissioning services, and commercial building energy simulations. A licensed professional engineer, he also provides expert witness testimony related to building enclosures and mechanical HVAC systems.

Mr. Eliason has a wide array of experience dealing with the technical analysis and problem resolution of assemblies to determine conditions of building envelopes. Through document review, design review, on-site investigations, and computational modeling of building enclosure systems, he diagnoses imperfections in the building envelope and develops recommendations for repair strategies.

To diagnose and resolve construction and operation related issues in mechanical HVAC systems, he examines the operational performance of the mechanical system and potential interactions with building envelope systems. His experience extends to performing ASHRAE energy audits, energy modeling of new and existing buildings, building commissioning, and enclosure quality assurance across a variety of building project types including residential, commercial, industrial, institutional, historic, and adaptive reuse.
