2 BriefAn affordable, green design integrating thermal efficiency from sustainable and environmentally friendly materials to meet the Passivhaus retrofit design standards.Open spaces with maximum natural lightingResearch 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 AModernisation of buildings layout and design (bathroom & kitchens).Addition of elevators if deemed necessaryReduction of energy consumption to retrofit passive house guidelines and levelsSustainable 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 necessaryManagement and cost calculationsPhase BAddition of a green roof and/or green facadeAddition 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).

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);
