Case Study: Biella Retrofitting One

Short Description

Biella Retrofitting One is promoted by ATC Biella in collaboration with Federcasa and Aeneas. The upgrading energy covers all social housing, located in Biella, owned for the bulk of the Agency for Territorial House (ATC) and partly by some residual owners "ATC former tenants." The Compendium consists of three different real estate buildings, called A, B and C.

The project provides for the reduction in the number of power stations from 6 to 2 with co-generation plant. The aim of the document is to further assess the impact of the project and possibly suggest improvements during construction.

This project has the overall objective of producing significant energy savings for buildings, reducing CO2 emissions, and a progressive benefit for users of the energy. service.

It is obvious that one of the objectives included in the intervention, as it has been designed, is to improve the building-plant system in order to reach standard 20 ° C

Key Elements

Main Results

Summary data of the intervention carried out, compared with a ATC investment of 665,000.00 are:
No. windows replaced = 90
Isolation porches and basements = 3985
Loft insulation (m) = 3972

Central heat processed in substation = 6
New thermal power plants with cogenerators 60 Kw =2
Radiators with thermostat with accounting for heat = 934

Statements of the operator on the 2009-2010 season with the building-plant system
renewed, leading to the following figures:

- fixed rate of base = € 142,999
- MWh variable cost = € 82,809 (of which 77,604 including VAT 20%)
- Maintenance cost = € 4,797 (20% VAT)
- to deduct = white certificates - € 5,815
- 10% VAT = € 14,239
- VAT 20% (heating without cog.) = € 16,480

Total = € 255,509

The average € 1,587 per apartment.
