[en] The work presented here consists in developing an audit methodology, with appropriate
simulation tools and benchmarks. Several case studies are used to support, to test and to
illustrate these developments. Each case study is described according to a standard format, in
order to make the data easy to re-use in the future. The audit of the HVAC system consists in
analyzing the information available about actual energy performances and in identifying the
most attractive retrofit opportunities. Focus is given here to cooling energy consumption, but
it could never be completely dissociated from heating requirements. An example of case study
is presented in the paper to give a first idea of what could be the (difficult) task of the energy
auditor. One of the main difficulties comes from the too many information lacks. Filling these
lacks would require, in most case, more detailed energy records on site. Simulation models
may help a lot, for a better interpretation of on site records and also for a safe identification of
the most promising retrofit opportunities. Such models and examples of simulations are
presented in the paper.
