Software tools

IES Virtual Environment is a suite of software for dynamic thermal simulations. ENEOR uses this tool, which assists in the design of energy systems, as part of its complex dynamic thermal simulations and in drawing up a Measurement and Verification plan. The modules used are:

  • ModelIT: 3D modelling module
  • ApacheSim: Computing module for dynamic thermal simulations
  • ApHVAC: Module for designing ventilation systems
  • Radiance: Computing module for graduating and quantifying reductions in consumption
  • SunCast : Module for calculating solar benefits, assessing shading relating to the environment, testing solar protection devices

Perrenoud is a regulatory thermal calculation software package, in accordance with the French energy efficiency regulation calculation rules. As part of its work as energy project owner, ENEOR performs the statutory calculations using this software.


Pinch analysis

ENEOR uses an industrial thermal audit software package. Capable of incorporating any type of thermal process up to average temperatures, we use pinch analysis to scale the recovery of heat from the processes

The RETScreen software suite is a decision support tool for assessing the generation of energy and energy savings, costs, emissions reductions, the financial viability and the risk of different renewable energy technologies and energy efficiency. In particular, ENEOR uses it in drawing up its Measurement and Verification plans.
