3 INTRODUCTION Renewable energy sources are energy sources that are continually replenished. These include energy from water, wind, the sun, geothermal sources, and biomass Sources such as energy crops. In contrast, fuels such as coal, oil, and natural gas are non- renewable.

4 The history of daylight dates of course from beginning of time, starting with natural light entering the mouths of caves and earliest human shelters. After 1900 daylight was in competition with the various forms of artificial light up to less 100 years ago when even some schools and factories were built without any windows at al. At the middle of 1960s, increasing cost of fossil fuels and finite life of electric sources impel architects and designers to start rethinking of less tangible aspects of day lighting and its relation ship with human sprite. HISTORY OF USING NATURAL LIGHT Afte r 1900 Middle of 1960 Re thinking about the benefits of natural light Increasing cost of fossil fuels and finite life of electric sources Having relationship with human sprit, increasing quality of life, more healthy and economic

5 WAYS TO USE NATURAL LIGH (SUNLIGHT) There are several ways to use sunlight main way to bring daylight into space in different types. openings and fenestrations solar technology photo-voltaic panelssolar hot water panels  The main focus of this presentation is based on SOLAR ENERGY (these capture and store the sun’s heat via water storage systems) these convert energy from daylight into electricity

6 Solar technologies use the sun's energy to provide heat, light, hot water, electricity, and even cooling, for homes, businesses, and industry. Despite sunlight 's significant potential for supplying energy, solar power provides less than 1% of U.S. energy needs. This percent age is expected to increase with the development of new and more efficient solar technologies. Hydropower Wind Power Solar Power Geothermal Power Biomass Power References Related Links Renewable Energy Sources

7 HISTORY OF USING SOLAR ENERGY using the sun to dry dead bodies (mummification) Ancient Egyptians 3rd Century B.C. Greek soldiers burned Roman’s fleet by using mirror to focus sunlight 100 A.D. Using mica window to stored heat of sun and later gave it off (by a historical writer ) 1767 the world's first solar collector was built by Swiss scientist 1891 the first commercial solar water heater was patented by the father of American solar energy, Clarence Kemp. mid-1950's the first solar water heated office building was built by architect Frank Bridgers Mid-1990's have few tax credits and incentives for solar electric homes or heating systems, yet approximately 1.2 million buildings in the US are solar heated.

8 CASE STUDIES 1.Solarsiedlung am Schlierberg, (in English: “Schlierberg Solar Estate”)Germany 2.Heliotrope (building) 3.Eastern Sierra Residence 4.Beddington Zero Energy Development 5.Solar Umbrella House 6. First Light House

9 CASE STUDIE 1.Solarsiedlung am Schlierberg, Freiburg (Breisgau), Germany (in English: “Schlierberg Solar Estate”) Architect: Rolf Disch Name: Solarsiedlung am Schlierberg (in English: Schlierberg Solar Estate) Location: Am Schlierberg, Freiburg (Breisgau), Germany Latitude/Longitude: 47° 59' 43" north, 7° 51' 11" east Time period from project idea to realization: approx. 10 years

10 All roofs are covered with standard large area Photovoltaic (PV) modules which are smartly integrated in a plane above the south facing roofs of the different buildings. The total system size is 445 kW p.

11 PV-System semitransparent PV-laminates are integrated into a plane with an air-gap of 16 cm above the south facing roofs of the terrace-buildings. The PV-modules are mounted point-wise on 30 mm RHS (rectangular hollow section) stainless steel profiles which themselves rest on hot-dip galvanized 100 mm I-beams. The roofs water barrier consists of a plastic-sheet sealing layer. Structurally, and therefore also legally, the PV-Array and roofing are two separate units.

12 In total 445 kW p of grid-connected PV is installed. The string inverters are mounted right under the roof deck on the building exterior walls. The total annual solar electricity production is 420 000 kWh. This, together with the energy efficient building design, allows for 2 million kWh primary energy savings per year. This is the equivalent of 200 000 l of oil per year.

13 enjoying living in a solar home and contributing to a resource efficient life style benefits from the good inner-city location easy and short access to public transport facilities nearby an infrastructure appropriate for children (no cars etc.) less illness due to a healthy indoor climate/air quality finding the social environment they are looking for [3] Occupant’s Feedback Occupants report that they enjoy living in the Solarsiedlung am Schlierberg. They experience a variety of benefits compared to occupants of conventional settlements. For example:

14 CASE STUDIE 2. Heliotrope Architect: Rolf Disch Name: Heliotrope Location: Freiburg-Germany (Heliotrop Rotating House)

15 The Heliotrope in Freiburg was the first building in the world to create more energy than it uses, of which is entirely renewable, emissions free and CO 2 neutral.

16 Its Special Structure Rotating House just like a sunflower

17 The structure physically rotates to track the sun, which allows it to harness the maximum natural sunlight and warmth possible. as the house was named, actually turns with the Sun to take full advantage of its light, which is not only used to produce electricity, using solar panels, but also illuminates the house during the entire day.

18 Slowly, the home turns to follow the Sun's apparent movement in the sky, thus always benefiting from an ideal incidence angle made by light rays on the solar panels, with maximizes their efficiency, also occupants will have nice view of around.

19 These innovations in combination with the superior insulation of the residence allow the Heliotrope to produce anywhere between four to six times its energy usage depending on the time of year. Several different energy generation modules are used in the building A 603 sq ft (56.0 m 2 ) dual-axis solar photovoltaic tracking plane a geometrical heat exchanger combined heat and power unit (CHP) solar-thermal balcony railings to provide heat and warm water. The Heliotrope is also fitted with a gray water cleaning system and built-in natural waste composting.

20 CASE STUDIE 3. Eastern Sierra Residence Architect: Arkin-Tilt Architects Name: Eastern Sierra Residence Location: Gardnerville, Nevada, United States

21 Passive and active technologies come together to create an energy-efficient and environmentally responsive home in a hot, arid climate with cold winter winds, east of the Sierra Nevada Mountain range In this region of the United States, which on average sees over three hundred sunny days a year, solar energy is ideal. www.tar gets-

22 Integrated photovoltaic laminates are installed on the sloped standing seam metal roof to provide electricity for the house. The support brackets are adjustable, so the panels may be rotated to catch seasonal sun angles and help shed the build-up o f snow. 1 Soar hot water collection 2 Heat exchange for domestic hot water 3 Thermal storage sand bed 4 Night flush cooling 5 High clerestory 6 Passive solar heat gain 7 Glass floor tiles for daylight 8 PV array shades trellis 9 Roof-integrated PV laminates 10 Trombe wall warms batteries 11 Inverters connect to grid 12 Green house adds humidity On the south side of the house, an angled row o f seven collector panels carry a heat-absorbing fluid to a heat exchanger. The tubes then form loops in sand beds under the floor plate o f the ho me to warm the interior space through radiation. No fossil fuels are required.

23 CASE STUDIE 4. Beddington Zero Energy Development Architect: Bill Dunster Name: Beddington Zero Energy Development Location: London

24 BedZED is the UK's largest eco-village. The aim was to help residents and office workers reduce their ecological and carbon footprints to a sustainable, "one planet" level. The plans cover reducing energy use providing renewable energy minimizing the embodied energy of the buildings reducing fossil fuel miles and also tackling food, waste, water usage and flooding. The BedZED Development design meets very high environmental standards, with a strong emphasis on roof gardens, sunlight, solar energy, reduction of energy consumption, and waste water recycling. In terms of materials, BedZED is built from natural, recycled, or reclaimed materials. All the wood used is approved by the Forest Stewardship Council or comparable internationally recognized environmental organization

25 Using passive solar techniques, houses arranged in south facing terraces to maximize heat gain from the sun. Each terrace is backed by north facing offices, where minimal solar gain reduces the tendency to overheat and the need for energy- hungry air conditioning. A centralized heat and power plant (CHP) provides hot water, which is distributed around the site via a district heating system of super- insulated pipes. Should residents or workers require a heating boost, each home or office has a domestic hot water tank that doubles as a radiator. The CHP plant at BedZED is powered by off- cuts from tree surgery waste that would otherwise go to landfill.

26 Zero energy The project is designed to use only energy from renewable sources generated on site. There are 777 square meters (8,360 sq ft) of solar panels. Tree waste fuels the development's cogeneration plant (downdraft gasifier) to provide district heating and electricity. The gasifier is not being used, because of technical implementation problems, though the technology has been and is being used successfully at other sites.


28 CASE STUDIE 5. Solar Umbrella House Architect: Paul Rudolph Location: California - United States Project Type: Residential – Single-Family attached

29 inspired by Paul Rudolph’s Umbrella House of 1953, the Solar Umbrella provides a contemporary reinvention of the solar canopy—a strategy that provides thermal protection in climates with intense exposures. Nestled amidst a neighborhood of single story bungalows the residence establishes a precedent for the next generation of California modernist architecture. Located on a 41’ wide x 100’-0” long through lot, the new addition transforms the architects’ existing 650 square foot bungalow into a total 1,900 square foot residence equipped for responsible living in the twenty-first century.

30 The architects carefully considered the entire site, taking advantage of as many opportunities for sustainable living as possible. Passive and active solar design strategies render the residence 100% energy neutral.

31 Recycled, renewable, and high performance materials and products are specified throughout.

32 CASE STUDIE 6. First Light House The Meridian First Light House, Solar Decathlon / Team Victoria University of Wellington in New Zealand New ZealandNew Zealand is the first country in the world to see the light each day, this gave the house its name— First Light.

33 The house has been designed to maximize energy drawn from the natural climate using a combination of passive and active energy strategies. The result is an efficient and comfort-controlled house that consumes less than a third of the energy of a typical NZ home.

34 The First Light house has a 6.3kilowatt solar array with 28 polycrystalline photovoltaic panels from Mitsubishi Electric that convert energy from the sun into electricity to be used in the house. Each panel consists of a group of silicon wafers that are connected electrically and packaged into a frame. The panels generate electrical power by converting solar radiation into direct current electricity. The system generates enough power to run the house throughout the year by collecting extra power during the sunnier months to be used during times of the year when sunshine hours are reduced. Solar Power

35 Hot water accounts for one third of residential energy use in the U.S. The First Light house has 40 evacuated tube solar collectors from LEAP Australasia Ltd that use energy from the sun to heat water for all of the houses hot water needs. Hot water

36 The canopy provides independent support for the 6 kW solar array consisting of 28 polycrystalline photovoltaic panels and 40 evacuated tube solar collectors. Essentially creating a second roof means the Butynol membrane roof below remains uncompromised by the supports for the PV panels. In the warmer seasons when the sun is high the canopy also provides shade to the large windows below
