ERASMUS IP project “Sustainable refurbishment, retrofit and energy management in residential buildings” Sustainable Refurbishment, Retrofit, Energy Management in Residential Buildings Corsica project 10.05.14 - 25.05.14 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)

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 Modernisation of buildings layout and design (bathroom & kitchens). Addition of elevators if deemed necessary Reduction of energy consumption to retrofit passive house guidelines and levels Sustainable energy production (secondary system). Sustainable building materials & construction to be implemented as much as possible in the retrofitted building. balcony renovation and/or addition of balconies, if deemed necessary Management and cost calculations Phase B Addition of a green roof and/or green facade Addition of a student community house built in sustainable timber materials, containing: computer studio, toilets, relaxation/party room, small kitchen and outside terrace area. Sustainable energy production (secondary system).

Phase B Wall System Floor plan 2 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 Kitchen Computer room Toilets Party Room Terrace (green roof)

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

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

Change of the energy demands Today After renovation

Energy Efficiency - Lighting

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.

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;

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);

Consumption and costs per year Conventional lamps Total (kWh) Costs 30000 4,416.00 € Proposal lamps Total (kWh) Costs 6394.8 941.31 €
