Positive energy buildings
As a thermal and fluid engineering consultancy, we can perform all the studies and investigations required for new builds. We aim to ensure the superior comfort and long-term service life of the recommended solutions as part of a lifecycle costing approach.

We are driven by our ambition to design buildings that produce more energy than they consume (positive energy building). These aims are already targeted by a number of ambitious schemes (BEPOS-effinergie) as a way of preparing for France’s future 2020 Building Energy Efficiency Standards. Energy transition legislation focuses on the development of positive energy buildings, including a charter signed with construction professionals and the constructability bonus scheme, which aims to absorb the extra costs associated with achieving exemplary energy performance.

We deliver services in the following fields:

Thermal engineering
Statutory thermal studies and labels
High-performance building envelopes
Summer comfort (dynamic thermal simulation)

HVAC engineering
HVAC (heating, ventilation and air conditioning)
Heating networks

Plumbing
Supply and drainage
Rainwater harvesting and management

High-power & low-power electrical engineering
Smart buildings: building management systems
Self-consumption monitoring and management

Renewable energies
Thermal and photovoltaic solar energy (grid-tied or self-consumption)
Geothermal and aerothermal energy

Acoustical engineering
Acoustic comfort

Financial engineering
Lifecycle cost analysis
Financing studies (including subsidies, energy efficiency credits, and so on)
