Energy audit of buildings
An energy audit is the primary step to evaluate a building and construct a suitable program of energy efficiency improvements.
This complete diagnosis allows for an overview of the energy performance and the obsolescence of the building, to identify the sources of energy savings and identify solutions to be implemented according to technical and economic opportunities.
Our audit provides a tool to support your decisions including:
- A technical analysis of the structure, facilities and contracts
- A building energy simulation
- An architectural and urban synthesis
- Improvement solutions tailored to the energy performance of buildings
- Detailed planning of the improvement program
- A study of funding solutions
A structured approach in 4 steps to improve energy efficiency
Our approach is suitable for all types of buildings, whether residential, commercial, industrial or for mixed use.
In 4 main stages, we accompany you from the site review to the programming of the works:
Our audit may be carried out alongside an improved energy performance diagnostic (EPD) or alongside an energy policy consulting to make the energy improvement solutions and economic data more reliable. The scope covered by our analysis ranges from a building to a full city portfolio of buildings a lessor or to a private portfolio.
Several studies can complement the audit to address specific issues.
Dynamic thermal simulation (STD)
To adjust the heating and cooling systems, improve the thermal comfort of buildings or renovate a Low Consumption Building (LBC), it is often necessary to improve the accuracy of calculations and use of powerful dynamic thermal simulation tools.
3D Modelling of the building takes into account all the necessary parameters for a comprehensive approach:
Dynamic thermal simulation is a real support tool in design and decision step, to optimize the energy performance of buildings, ensure optimal thermal comfort and reduce operating costs.
- Technical Audit including major maintenance
- A “blower door” test – QUALIBAT ALTEREA – These tests quantified the initial sealing capacity & recommend solutions
- Feasibility study of energy supplies, including opportunities for renewable energy
- Energy Strategic Plan to establish the program of works of the portfolio of the buildings
Using our technical and financial expertise we support you along in all the stages of your project
