2  Problem Statement  Conceptualization: assessment of customer needs and the resulting weight of importance  Preliminary Design: brainstorming, sketches, re- design concepts  Detailed Design: CAD drawings, detailed sketches and dimensions  Production: bill of materials, engineering analysis

3  BIPV is the future of solar electricity and buildings. Rather than having separate elements for electricity production and building envelope (the roof, walls, windows, and doors), BIPV reduces cost and improves designer creativity by combining functions. Although the Solar D building envelope is still being conceived, this project can provide strategic information and support for the architectural design team. Emphasis in this project is on a thorough review of the literature and characterization of the kinds of BIPV systems that have already been developed, followed by the creation of new combinations or radically new ideas. Physical models, CAD drawings, wiring details, and performance analysis are all important aspects of this project. (from SEDTAPP website)

4  An effective BIPV system combines functional aspects of architecture with energy collection. BIPV systems primarily rely on the solar power. To accurately design a BIPV system, our team must use CAD to draft a model of the house, and create in it a BIPV system. The focuses of our project are to create a design that is aesthetically pleasing. The second need is to make a final product which is efficient in collecting light from the sun, which will reduce (if not eliminate) the use of external electricity. The third and final aspect of the customer needs is to make the design cost efficient and easy to produce.


6  Aesthetically pleasing  Efficient  Creative  Innovative  Property Aligned  Cost-efficient  Easy to produce  Suitable for existing “Solar D” house

7 Solar panels  Roof  Siding  Overhangs/Awnings  Shutters  Lawn Gnomes Solar capacitors  Basement Solar water heaters  Along siding  Along gutters

8  An awning over the porch be built Optimization of solar collection The inclination of the house does not accommodate the direction of the sun during its most brilliant stages


10  The gutter system contains panels which collect sun and transport water. Convenient and necessary location Dual-purposed Makes direct contact with the sun over a large surface area during its most brilliant stages Connected to the house, so wiring can be easily managed.

11  Solar lawn gnomes (and other lawn accessories) Can be placed in open space and re- routed to areas outside the house Could be self powered (i.e. lamp post) Very radical

17  Back-Contact Silicon PV Panels All electrical components on back of cell – leaves more exposure to the sun

18  Microinverters All BIPV panels produce DC current – we need AC A more compact, cost effective, and inexpensive way to produce AC

19  Light-Concentrating PV Panels Uses lens technology to concentrate sunlight onto panels Increases power output to the equivalent of 326 suns

20  Thin Film Panels Silicon is expensive Other materials are also expensive, but require much less material and are thus less costly.

21  Solar Thermal Storage AKA “Solar Capacitors” Instead of selling electricity when you no longer need it anymore, you can store it Still early on in research

22 ItemCost 2.28 kW Solar System$14,257.57 Lawn Gnomes4 x $15 = $60 Awning material and Assembly $3,000 est Total (including tax rebates)$10,160 to $13,040

23  Our decision is to go with a complete system from Alter Systems.  The cost of an entire system is currently $14,257.57.  The final cost will range from $7,100 to $9,980 including tax credits and incentives. evergreen-190-watt-solar-panels-and-fronius-ig-2000-p-1702.html

24  We as the united team of America feel that we have successfully designed a BIPV System which effectively accomplished our main goals: Aesthetically appealing Reduced external electricity Cost effective Easy to produce  We were able to incorporate our ideas and concepts into an appealing, multi-functional, green house.
