Energy Efficiency


We support project owners and project managers on the Energy component of their projects according to a 3 steps approach:

Energy sobriety through work on passive buildings and bioclimatic design
Energy efficiency of MEP systems
Renewable energy and smart grid

For carrying out energy efficient design, TERAO has all specific skills necessary to implement it for both new construction and renovation:

Bioclimatism and passive design
Modeling: Energy modeling, Computational Fluid Dynamics (CFD), Urban Heat Island
Certified Measurement and Verification Professional (CMVP)
Optimization and Low carbon energy (ENR&R, smart grid)

Energy audits of buildings and assets

  • Basic Audit: The basic audit is essentially based on invoices and onsite visits. No measurements are carried out on site, nor is a detailed inventory of equipment. The improvement solutions suggested are based on our experience and similar projects and are presented individually.
  • Intermediate Audit: The intermediate audit aims to understand the energy breakdown and overall consumption of the building thanks to a simplified model developed by TERAO. It includes all equipment seen on site, the presentation of improvements, include technical feasibility, financial estimations, return on investment, etc… Some measurements are carried out on the site.
  • Premium Audit: The premium audit is a detailed and accurate audit of the building and of its possible optimizations. It is based on a thermal model calibrated on invoices and in which the envelope and MEP system are modeled. Measurements are carried out on site, for example, measurements of IAQ, Temperature, lighting level. The action plan is designed to be integrated into a multiannual work plan or in technical documents in the case of a complete renovation. Savings and cost estimation are therefore reliable.
