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
HOUSE DESIGN 2.Environmental friendly building materials 3.Economic Consideration
ELECTRIC GENERATION FROM SOLAR
Bioclimatic Architecture Location Shape of the house Orientation
Bioclimatic Architecture Active solar collecting
Bioclimatic Architecture Passive solar collecting –Direct systems –Semi direct systems –Indirect systems
Bioclimatic Architecture Isolation and thermal mass
Bioclimatic Architecture Climatic use of soil Stopper rooms. Protection from summer radiation
Bioclimatic Architecture Earth Translation
ENVIRONMENTAL IMPACT AND SAFETY
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
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.
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.
Environmental Impact and Safety Green Building Materials Interesting examples of Green Building Materials: -Straw Bale
Environmental Impact and Safety
-Straw Bale * Great insulation properties * Availability *Non-toxic *Needs little processing
Environmental Impact and Safety -Recycled Cotton/Polyester insulation: * Made from blue jeans scraps * Avoid using fiberglass * Safe product for the workers
Environmental Impact and Safety -Autoclaved Aerated Concrete: * High thermal insulation * Completely recyclable * Very durable material * High indoor air quality
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
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 more money than was lost from weather related disasters from 1980 to 1990 ($82 Billion).
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 Source - Associated Press, November 28,1998.
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
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.
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.
THE COST INITIAL COST OPERATIONAL COST
INITIAL COST Including the fee of equipment, such as PV panels, mounting hardware, original battery set etc. and the installation fee
Flat collector Costs Detached house – hot water 5 m²: SEK Comb system 12.5 m²: SEK Multifamily house: 3000 SEK/m² Solar district heating: 2000 SEK/m²
OPERATIONAL COST Including battery replacement and the cost of backup generator power during the winter months
A SIMPLE MODEL P T t p solar other o M
Why is it so expensive High cost of raw-material High designing fee Low competition Long run to pay back
Governments policy Why needs the policy support? reduce the cost of private invest shorten the time of paying-back
how does it work? P T other solar subsidy
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
HOW THE POLICY INFLUENCED
Japan: directly finance 70,000 roofs program : Government finance 50% of the initial cost of the 3-to 4-kW grid- connected residential systems
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.
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.
Sun Slates (Solar Roof)
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.
