Abstract
Remedial actions and restructuration works enhancing the energy performance of a building should be evaluated by comparing the baseline and the situation improved, i.e., that which is achieved after the retrofit measures will be implemented. This comparison may be done, as a function of the operating level of the audit, using simplified methods or by evaluating the global effects, through a complete energy assessment by means of simulation software. This chapter examines the issues of the evaluation of the performance improvement and provides the elements of choice to provide an approach consistent with the operational level adopted.

Notes
- 1.
The average seasonal efficiency of a HVAC system considers the energy losses of the different subsystems: heat generation, pipes and ducts distribution, regulation or control and emission of the terminals.
- 2.
In design, operative temperature can be defined as the average of the mean radiant and ambient air temperatures, weighted by their respective heat transfer coefficients [1].
