Subject: Residential building energy audit

Location: City of Anagni (FR)

Client: Sintec S.r.l.

 

Description:

The objective of the audit is to see the current status of building energy consumption and understand the main activities by evaluating the energy savings can be achieved. It is the first essential step for the condos that decide diridurre energy consumption. To carry out an audit of the building were collected consumption data and energy costs, and also data on electric utilities, heat, water (power, demand / consumption time, duty cycle, etc.).. On this basis, the models are reconstructed energy. From these models, it was possible to derive the distribution of power and consumption by type of use. The energy situation has been analyzed and compared with the average parameters of consumption to identify improvements to reduce fuel consumption and costs, and the preliminary assessment of the technical and economic feasibility. In particular, the building, constructed in masonry and reinforced concrete, is not equipped with proper insulation, and you are having moisture problems resulting stains on the walls in the apartments, the heating is with traditional radiators, windows are single-glazed, with exterior shutters.

Calculation results have allowed us to identify areas with greater dispersion of energy and the main problems:
- Isolation inefficient
- Inefficient windows 
- Moisture problems

 

and improvements:
- Replacing windows with new high energy performance
- Isolation of the component top closure (cover) with further specification of ventilated roof
- System insulating coat with reference to the external vertical closures


Thanks to these measures, it was possible to achieve the energy efficiency class C, from the initial G, with an annual cost savings of approximately € 2,500, a savings of 50% on the bill.
