1 ERASMUS IP project “Sustainable refurbishment, retrofit and energy management in residential buildings” Sustainable Refurbishment, Retrofit, Energy Management in Residential Buildings Corsica project Morten Toft Jacobsen (VIA UNI) Carlos Ramos (IUT of Corsica) Selin Torun (UOW) Elisa Taccioli (Unibo) Alina Mukharova (HTW) Indrek Soots (TKTK) Joao Pinto (IPB)

2 Brief  An affordable, green design integrating thermal efficiency from sustainable and environmentally friendly materials to meet the Passivhaus retrofit design standards.  Open spaces with maximum natural lighting  Research was put into identifying the most modern and energy efficient materials available to ensure a new way of life for students/occupants that does not cost the earth! Phase A o Modernisation of buildings layout and design (bathroom & kitchens). o Addition of elevators if deemed necessary o Reduction of energy consumption to retrofit passive house guidelines and levels o Sustainable energy production (secondary system). o Sustainable building materials & construction to be implemented as much as possible in the retrofitted building. o balcony renovation and/or addition of balconies, if deemed necessary o Management and cost calculations Phase B o Addition of a green roof and/or green facade o Addition of a student community house built in sustainable timber materials, containing: computer studio, toilets, relaxation/party room, small kitchen and outside terrace area. o Sustainable energy production (secondary system).

4 Conceptual climate and weather analysis Wind analysis

5 Conceptual climate and weather analysis Focus areas

6 Keywords for choice of materials Life spanEnvironment Cradle to cradle Use of C02 (production) Communnity

7 Floor plans (Phase A) level 1 level 2 level 3 level 4 level 5 Types of apartments Single rooms Disabled rooms Dublex (2 single rooms + 2 double rooms) Kitchens and common space

8 Average area: 14 m2 Number rooms: 44 Single room Disabled room DublexKitchen and common space Average area: 110 m2 Number rooms: 2 Average area: 25 m2 Number rooms: 6 Average area: 25 m2 Number rooms: 2

9 Phase B Kitchen Computer room Toilets Party Room Terrace (green roof) Floor plan 2 Wall System Structural Insulated Panels (SIPs) Offer fast-track, lightweight building solutions Cost effective approach and are quick and easy to install Manufactured using high-pressure foam injection to create strong composite panels that can be used as wall, roof and floor panels to create highly efficient structures. U-value of 0.14 W/m2K

10 Automatic taps o Reduces the usage of water o Saves money. Materials Ceramic tiles in all apartments, kitchens and bathrooms o Secure long life span o Cheap purchase cost because of the large quantity o Benefit of thermal mass, for natural heating..

11 Internal insulation regarding sound 63 dB Fire class A2-s1,d0 (Class1) Light reflection 70 – 75 % L´n,w value (impact sound) Walls: 12,5mm of gypsum board W. 30mm of Styrofoam glued on the backside. Ceilings: 12,5mm perforated gypsum board W. 30mm of Styrofoam glued on the backside. Total thickness 145 mm (2 x 12,5, 95mm, 2 x 12,5) Fire value EI60 R´w value 52 Air bourne sound Solar reflection 82% (white 9010) New internal walls Regular gypsum on wood sound values (0,6)

12 Staircases 1. Control unit with emergency power backup for 1 window 2. Smoke ventilation window 3. Alarm buttons 4. Ventilation switch 5. Smoke sensor 6. Rain sensor Characteristics Expulsion of heat and smoke during fire: -automatic or manual opening of FSP smoke ventilation window in the event of fire -increased safety -building ventilation and automatic window closing after fixed time.

13 External walls Renovated wooden and green facade:  Aiming for natural facade materials  U-value of 0,11 with 200mm insulation  Minimizing thermal bridges while designing  Anchors for cladding  Only 230mm mass concrete will remain

14 Connection of transforming balcony

15 Different facades connected together

16 Ventilation system  Little ventilators with heat exchanger above windows  Heat recovery percentage of 45  Covers single and double persons fresh air needs  Extract fans in bathrooms and kitchens  Solar electricity mostly satisfies the extract air ventilator’s demands

17 Change of the energy demands  After renovation  Today

18 Energy Efficiency - Lighting

19 Why is it important? The efficient use of energy and the resulting cost savings are, nowadays, a concern not only of governments and officials as well as the general population. This concern increases when it becomes aware that it is not merely a matter of saving or, if you prefer not to spend, but also to preserve the environment that surrounds us. Thus, environmental concerns, such as CO2 emissions to the atmosphere and the consequent rise of the planet and increase of the ozone hole temperature, take paramount importance in our daily concerns.

20 The proposal  Replacing existing light bulbs with more efficient bulbs;  Combine energy efficiency and lighting quality;  Maintain comfort and user satisfaction;  Reduction in electricity consumption and costs;

21 Characteristics of lamps to check before their replacement  Luminous Flux (lm);  Power consumption (wh);  Efficacy (lm/W);  Color temperature (appearance of light) ;  Refund chromatic (IRC);  Life time (h);

22 Consumption and costs per year Conventional lamps Total (kWh)Costs , € Proposal lamps Total (kWh)Costs €

23 Savings per year Energy savings (kwh)Money savings , €

24 Investement Proposal lamp 1 (rooms) 2, € Proposal lamp 2 (rooms) 1, € Proposal lamp 3(rooms) € Proposal lamp (toilets) 1, € Proposal lamp (corridors) € Total 5, € Return on Investment approximately in two years

25 Putting sensors in the corridors  The sensor can reduce energy consumption 30 % Reduction per corridor per year (kwh) Consumption per corridor without a sensor per year (kwh) Total (kwh) Consumption per corridor with a sensor per year (kwh) Total (kwh)

26 Savings with sensors per year Energy saving (kWh)Saving money € Investment (sensors) / UnityTotal €522.84€ Return on the investiment approximately in seven years

27 Final estimate Total consumption per year (kwh) Cost per year €

28 Green Façade Allows vegetation to grow Products clean air Easy on the eye Acoustic insulating Recyclable cages Protects the building from direct sun light Sphagnum in metal cages

29 Green Façade House on Paris’ 2nd arrodissement

30 Windows Two way opening shading Detail Wooden frame with a plastic layer on the outside. Double glazed low emisivity window. Layer of argon between the windows Components U value 0,73 W x m -2 x K -1

31 Window/ Balcony

32 Green Roof + Solar Panels  48 solar panels produce kwh/year  By using a green roof on phase A we would save the environment from the emission of 710 kg CO2 compared to installing of another roof type.

33 Green Roof structure Water/DP membrane Ridged insulation Galvanized trapezoid plates Skandek green line steel beams Mineral wool Fire protection Ceiling cladding U-value for the construction of 600mm is 0,08W/m2k Fraction point is between 100,5kNm to 146,7kNm Per. Beam The weight of the elements varies from 19kg to 24kg per. running meter. 100% recyclable 90 years durability

34 Roof constructions Terrace boards for the Phase B:  Low maintenance  Eco-friendly materials  60% reused wood + 30% high density polyethylene (reused plastic)+10% colour + UV stabilizer  The lifespan of the boards of 25 to 30 years and are 90% reusable. Stands for terrace:  stands/feet are 100% reusable  not affected by any atmospheric impacts (UV/t)  The load of each foot is distributed to an area of 320 cm2

35 Comparison of the existing and new building Saving ,95€

36 Comparison of the existing and new building Saving 36 T/co2/yr Savings over 30 years = 1080 Tons/co2 108 times around the world for one car Co2 emission of 90 amr. Homes for one whole year
