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) Slide 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. Slide 5 Slide 6 Aesthetically pleasing Efficient Creative Innovative Property Aligned Cost-efficient Easy to produce Suitable for existing Solar D house Slide 7 Solar panels Roof Siding Overhangs/Awnings Shutters Lawn Gnomes Solar capacitors Basement Solar water heaters Along siding Along gutters Slide 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 Slide 9 Slide 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. Slide 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 Slide 12 FUNCTIONART ShinglePanelsBracketRectangular frame elements Rail/Tracks Systems5497587 Solar Cell40408674336413 Mounting6959517 Framing System7012188 Module Positioning7260918 Function ShinglePanelsBracket Rectangular Frame Elements Rail/Tracks Systems5497587 Solar Cells40408674336413 Mounting6959517 Framing System7012188 Module Positioning7260918 Slide 13 CostAestheticsEfficiencyLifespanTotalWeight Cost131/415.25.198 Aesthetics1/311/61.75.066 Efficiency461213.491 Lifespan141/216.5.245 Slide 14 CostAestheticsEfficiencyLifespanValueRank Weights.198.066.491.245 AwningBASE02 Pillars0010.0471 Gutter 5 Walkway100-0.1323 Lawn Gnome010-0.4254 CostAestheticsEfficiencyLifespanValueRank Weights.198.066.491.245 Awning10110.9341 Pillars00010.2453 Gutter 0 -0.5095 WalkwayBASE04 Lawn Gnome01010.3112 CostAestheticsEfficiencyLifespanValueRank Weights.198.066.491.245 Awning10110.9341 Pillars10010.4432 Gutter0 -0.8025 Walkway000-0.2454 Lawn GnomeBASE03 CostAestheticsEfficiencyLifespanValueRank Weights.198.066.491.245 Awning10100.6891 PillarsBASE03 Gutter00 -0.4435 Walkway01000.0662 Lawn Gnome10 -0.1794 CostAestheticsEfficiencyLifespanValueRank Weights.198.066.491.245 Awning11111.0001 Pillars11010.5092 GutterBASE05 Walkway00100.4913 Lawn Gnome11000.2644 Slide 15 Slide 16 Slide 17 Back-Contact Silicon PV Panels All electrical components on back of cell leaves more exposure to the sun Slide 18 Microinverters All BIPV panels produce DC current we need AC A more compact, cost effective, and inexpensive way to produce AC Slide 19 Light-Concentrating PV Panels Uses lens technology to concentrate sunlight onto panels Increases power output to the equivalent of 326 suns Slide 20 Thin Film Panels Silicon is expensive Other materials are also expensive, but require much less material and are thus less costly. Slide 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 Slide 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 Slide 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. http://www.altersystems.com/catalog/228-kw-gridtied-solar-system-with- evergreen-190-watt-solar-panels-and-fronius-ig-2000-p-1702.html Slide 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.
