Energy Saving Group | Retrofitting Together 2.0 | Pilot Sites 1 - BORGO FURO PILOT SITE Heat recovery efficiency 80 [%] 1. Ground floor and top floor slab insulation First design 2. Residencial external walls insulation, insulated jambs. 3. Replacement of the existing metal windows with triple- glazed low-emissivity wooden aluminium ones (Uw =1,2). 4. New insulated boxes, electric blinds, insulated metal thresholds. 5. New condensing boilers (high efficiency water heaters). 6. New aluminum windows in the stairwell and in the entrance. 7. New security door in each apartment and painting stairwell walls and celings. 8. New verandas ( no thermal bridges on the wall) 9. New coat roof (with takeaway in tiles, laying waterproof membrane, repositioning of tiles and possible integration of non-reusable). 10. Safety lines on the roof. 11. Limitation devices against the consumption of water 12. CMV systems with heat exchangers : the controlled ventilation systems for energy recovery allows partial recover of heating or cooling energy that would be lost with simple air change (for example by opening windows). 13. Drywall celings in bathroom and corridors 14. Replacement of the overpanel interior door 15. CMV : Main aspirators (for the removal of stale or polluted air) and main speakers (for fresh air inlet) are positioned out of existing verandas through a suitable panel.

Energy Saving Group | Retrofitting Together 2.0 | Pilot Sites 1 - BORGO FURO PILOT SITE Thanks to the national law of funding, so- called “ Deceto Lupi ”, the new solution Iinclude ALL THE PREVIOUS New design PROPOSALS ACTIONS, and also adds: 1. Solar screens/blinds with daylight sensor (home automation) 2. Ventilated facade 3. Home automation to ventilation and solar screens control high budget small budget details In this solution, one obtains the natural circulation of air in the interspace, due to the convective motion produced by the presence of openings arranged at the base and at the top of the facade. Air movement in the cavity contributes to dry any water infiltration and to remove the heat accumulated solar radiation in the coating layer, including improving the thermal insulation of the wall during the winter. The interspace between the coating and the wall is designed in such a way that the air present in it can flow for chimney effect in a natural way (medium budget solution) and / or in artificially controlled way ( high budget solution with Details automation appliances). <pilot site name> | <company> | <name and surname> BORGO FURO DI S.

Energy Saving Group | Retrofitting Together 2.0 | Pilot Sites 2- DREEAM PROJECT - call EeB -08-2015) THE PROJECT PROPOSAL FOR CALL (EeB-08-2015) Horizon2020 - call "Integrated approach to retrofitting of residential buildings", EURHONET NETWORK - DREEAM PROJECT Demonstration of an integrated renovation approach for energy efficiency at the multi building scale The Project aims to demonstrate replicable Net Zero Energy (NZE) residential building renovation approaches achieving a reduction of 75% total Net Energy Demand . There is a need to develop and demonstrate a systemic approach that allows designing and operating ( socially, economically, technically, etc..) a cost-effective and replicable renovation solution package for balancing EE and RES to achieve NZE standards from the multi building perspective. DREEAM approach: • 60% EDR energy demand reduction + 15% REG energy generation • 3 pilot site, in different climate zone ( Italy, Sweden, UK) • Social and public housing – 360 dwellings • Higher ROI and 30% reduced payback • The Dissemination and exploitation activities will ensure that the project reach majority of EU social and public housing companies.

Energy Saving Group | Retrofitting Together 2.0 | Pilot Sites 3 – BUILDTOG++ : NEW PILOT SITE IN TREVISO Masterplan «Feltrina»: rebuilding and innovation in the “via Cisole” district . The social housing “Via Cisole ” neighborhood is characterized by a trapezoidal area of 20,258 square meters, including between the highway Feltrina and Via Castagnole , and it is situated in Treviso near the Rugby stadium. The settlement, built in 1949, is currently only partially inhabited and consists of 12 buildings with 8 units each, for a total of 96 apartments and 65 car garage in sheet metal. The Masterplan provides for the complete demolition and reconstruction of the old district in order to create a new zero impact neighborhod with approximately 150/200 new apartments. The Masterplan also includes a participatory planning with all stakeholders, with a Neighborhood Laboratory to envolve both t current inhabitants and all associations and organizations interested in. The project includes: • Zero energy buildings and ecofriendly architecture. • Geothermal and solar energy and photovoltaic • District heat pump system. • Home automation for the management of energy and water summer cooling. • Green buildings and houses with wooden frame/structure • Public park • Redesign of road and pedestrian links to the town center and neighboring districts • Permanent district laboratories younger - elderly + (new forms of social housing). • Partnering forms of public-private partnerships or project financing. <pilot site name> | <company> | <name and surname> DREEEAM PROJEC | ATER TREVISO | arch.
