Interventi di retrofit, IEQ e risparmio energetico

Traditional energy retrofit interventions focus on reducing energy requirements and costs, which can be achieved by acting on the envelope or on the plants, without taking into account that the conditions of indoor air quality and thermal, visual and acoustic comfort, provided for by current legislation, must be maintained. To the in place mea-surement campaigns of the energy parameters before and after the retrofit intervention, should be added those relating to the IEQ sectors. The results of the various measures in the field must be analyzed in synergy, using a rigo-rous or simplified approach, evaluating the sensitivity of energy costs to individual retrofit interventions, always on equal terms. This theme is addressed in all fields by the Operative Units 2 and 4. This paper presents an example case study that simply gives an idea of the problem.
