  2. Knowing the different types of energy audits and knowing how to choose the appropriate for each case.
  3. Identifying the role and the impact of the parameters determining the energy performance of buildings.
  4. Knowing how the main parameters that determine indoor thermal comfort, air quality, lighting and acoustics function and can be measured
  5. Knowing how the thermal protection and air-tightness of the building’s envelope can be measured
  6. Knowing how efficiency of HVAC systems can be measured
  7. Understanding how instrumentation has to be chosen, calibrated, maintained and used.
  8. Using appropriate software tools for the calculative types of audits
