1 RENEWABLE ENERGY [HOUSE DESIGN] ÁLVARO DE ANDRÉS EMMANUEL KYERE-FREMPONG QIAO HE ZHENHUA ZHANG GORKA BARRIO FERNANDEZ This presentation will probably involve audience discussion, which will create action items. Use PowerPoint to keep track of these action items during your presentation In Slide Show, click on the right mouse button Select Meeting Minder Select the Action Items tab Type in action items as they come up Click OK to dismiss this box This will automatically create an Action Item slide at the end of your presentation with your points entered.

2 HOUSE DESIGN Our focus is going to be on 1.architectural design of the house to make the maximum use of the sun energy. Such as: Location Shape Orientation

3 HOUSE DESIGN 2.Environmental friendly building materials 3.Economic Consideration

4 ELECTRIC GENERATION FROM SOLAR

5 BIOCLIMATIC ARCHITECTURE

6 Bioclimatic Architecture Location Shape of the house Orientation

7 Bioclimatic Architecture Active solar collecting

8 Bioclimatic Architecture Passive solar collecting –Direct systems –Semi direct systems –Indirect systems

9 Bioclimatic Architecture Isolation and thermal mass

10 Bioclimatic Architecture Ventilation. – Natural ventilation

11 Bioclimatic Architecture Ventilation. –Convective ventilation –Convective ventilation through attic

12 Bioclimatic Architecture Ventilation. –Ventilated façade.

13 Bioclimatic Architecture Climatic use of soil Stopper rooms. Protection from summer radiation

14 Bioclimatic Architecture Earth Translation

15 Bioclimatic Architecture

17 ENVIRONMENTAL IMPACT AND SAFETY

18 Environmental Impact and Safety When analyzing Environmental Impact in House Design we must take into account: Impact produced by the PV Energy System Impact produced by the Materials used to build the house

19 Environmental Impact and Safety Impact produced by the Building Materials: We can reduce the impact by using: A suitable material for the local climate. workersinhabitants the planet A healthy and safe material for the workers, for the inhabitants and for the planet.

20 Environmental Impact and Safety …… by using: A durable and easily maintained material. The material efficiently (little transportation and processing, recyclable content) An easily recyclable material.

21 Environmental Impact and Safety Green Building Materials Interesting examples of Green Building Materials: -Straw Bale

22 Environmental Impact and Safety

23 -Straw Bale * Great insulation properties * Availability *Non-toxic *Needs little processing

24 Environmental Impact and Safety -Recycled Cotton/Polyester insulation: * Made from blue jeans scraps * Avoid using fiberglass * Safe product for the workers

25 Environmental Impact and Safety -Autoclaved Aerated Concrete: * High thermal insulation * Completely recyclable * Very durable material * High indoor air quality

26 How about is the solar energy of usage present status. From the 1970s, many million of dollars were invested by governments,private institution, architectural and solar equipment firms toward the development of practical

27 Environmental Benefits Natural disaster costs soar to another world record. Violent weather cost the world a record $130 Billion in the first eleven months of 1998- more money than was lost from weather related disasters from 1980 to 1990 ($82 Billion).

28 Environmental Benefits Researchers from the Worldwatch Institute and Munich Re blame deforestation and climate change from Earth warming for much of the loss. The previous one year record was $90 Billion in 1996. Source - Associated Press, November 28,1998.

29 Environmental Benefits Reducing the carbon emission Rising carbon emissions were once favorably looked upon as a measure of economic growth and development. but now it doesnt Solar energy has no carbon emission and other pollutant gases

30 Solar energy benefit to environment and mankind Solar energy will become a form of Shell shock Shell Oil predicts that 50% of the world's energy will come from renewable sources by 2040.

31 Solar energy benefit to environment and mankind Solar energy is a clean, safe, renewable resource, that's pollution- free and protects the environment for future generations.

32 ECONOMIC CONSIDERATION

33 THE COST INITIAL COST OPERATIONAL COST

34 INITIAL COST Including the fee of equipment, such as PV panels, mounting hardware, original battery set etc. and the installation fee

35 Flat collector Costs Detached house – hot water 5 m²: 25000- 30000 SEK Comb system 12.5 m²: 50000 - 60000 SEK Multifamily house: 3000 SEK/m² Solar district heating: 2000 SEK/m²

36 OPERATIONAL COST Including battery replacement and the cost of backup generator power during the winter months

37 A SIMPLE MODEL P T t p solar other o M

38 Why is it so expensive High cost of raw-material High designing fee Low competition Long run to pay back

39 Governments policy Why needs the policy support? reduce the cost of private invest shorten the time of paying-back

40 how does it work? P T other solar subsidy

41 GERMANY:TAX-RETURN The solar products supplier promise to maintain the same price for 20 years industry can get the return of about 50 euro cents from the government per kilowatt-hour of electricity output composed of low-interest loans for 100,000 roofs program

42 HOW THE POLICY INFLUENCED

43 Japan: directly finance 70,000 roofs program : Government finance 50% of the initial cost of the 3-to 4-kW grid- connected residential systems

45 CONCLUSIONS

46 Conclusions The initial or the up-front cost of installing solar panels is very high therefore, making it hard for people to make decision whether to buy it or not. However, putting it together with the design and building of the house make more economical and competitive not even considering the environmental benefits.

47 Conclusions Further saving could be made by using solar roofing instead of normal roofing materials. The cost of roofing your house would be part of the cost of the solar energy.

48 Sun Slates (Solar Roof)

49 Conclusions Further more, professor Vivian Alberts who works at the University of Johannesburgs department of physics, has developed a revolutionary process to produce solar panels using CIGS (copper-indium-galliumdiselenide) instead of silicon. The final product is expected to cost a quarter of the price of current solar panels.

50 Any question? Thank you!
