    6. Borton-Lawsons Green Story Strive to be energy conscious and look for most efficient ways to design projects. Dedicated to minimizing energy consumption, reducing emissions, shrinking carbon footprint. Sponsoring EDSGN 100 Project just another step in maintaining balance between economic growth and environmental stewardship. Some example energy efficient projects completed by Borton-Lawson:

    7. Pine Street Revitalization Pine Street Neighborhood Revitalization located in Hazleton, PA commercial/residential area became largely vacant over the last decade. Used green technology to create highly efficient heating, cooling, ventilation, lighting and appliances can provide energy cost savings of about 30% over standard construction. Used photovoltaic systems on the southern-sloped roofs. Net metering allows residents the ability to transfer surplus energy to the local utility. 2008 Governors Award Winner for Environmental Excellence

    11. Steam System Audits U.S. Department of Energy Steam System Assessment Tools (SSST & SSAT) Industry professionals recognized as Qualified Specialists by the DOE after training class and rigorous exam. Qualified Specialists develop approximate models of real steam systems. Using these models, specialists apply SSST & SSAT to quantify the magnitude energy, cost, and emissions-savings of key potential steam improvement opportunities. Specialists apply this tool to help their plant or industrial customers identify ways to improve steam system efficiency.

    12. Steam System Audits

    13. Energy Cost Increases on the Horizon Electric Rate Caps Removal in Pennsylvania Rate caps froze electric rates at 1990s levels and were imposed on utilities as part of a deregulation designed to deliver lower bills in a competitive marketplace. Competition, however, has not flourished. In the last 10 years, environmental factors for electric generation and the prices of natural gas and coal have doubled both of those products are fuels used in the generation of electricity. While Pennsylvania consumers rates are capped, the market prices for electricity have risen just as the prices of other goods and services have risen, but electric rates were capped. Pennsylvanians could see home electric bills rise 40, 50 or even 60 percent by the time decade-old rate caps expire in the next few years.

    14. Solar Decathlon Overview

    15. PSUs Morning Star Home See for project info Whats a Decathlon about it? Architecture 200 points Dwelling 100 points Documentation 100 points Communications 100 points Comfort Zone 100 points Appliances 100 points Hot Water 100 points Lighting 100 points Energy Balance 100 points Getting Around 100 points

    17. Whats the Solar Resource?

    18. Seasonal Averages

    19. Estimating Photovoltaic (PV) Output PVs rated in power output when illuminated with 1,000 W/m2 of sunlight Output varies in direct proportion to sunlight intensity Therefore, power output is estimated using average solar radiation energy data and converting it into equivalent hours at a power of 1,000 W/m2

    20. Estimating PV Output

    21. EDSGN 100 Projects Nexus: Technical Core BIPV: Building Integrated PV Solar Clothes Drying Daylighting

    31. A Systematic Approach Identify services/functions Identify & characterize subsystems Consider how to minimize loads Consider how to reclaim energy & materials Consider how to use natural principles and sustainable materials Analyze performance of concepts Consider the bigger pictures

    32. Project A: Technical Core

    33. Project B: Building Integrated PV

    34. PV comes in 3 basic types

    35. BIPV on Roofs Considerations for mounting rooftop PV system: Module physical and electrical characteristics 2. Array thermal and electrical performance 3. Array orientation, location and site conditions 4. Roofing and structural-related issues 5. Building thermal performance 6. Weather sealing 7. Electrical integration 8. Installation, labor, and maintenance 9. Materials and environmental compatibility 10. Aesthetics and architectural integration 11. Economic factors and costs

    36. Steps in designing a BIPV system

    37. BIPV Challenges Solar D house needs lots of power, ?c-Si or p-Si is needed c-Si & p-Si panels work better when cooler Individual cells or modules can be integrated with windows (wires?) Shadows are bad

    38. Grid-tied PV System

    39. Project C: Solar Clothes Dryer Electric clothes dryers use 900-1500 kwh/year At $0.10/kwh, costs $90-$150/year (cost will be even higher after electric rate caps are removed) The dryer is typically the second-biggest electricity-using appliance after the refrigerator Solution

    40. Project C: Solar Clothes Dryer

    41. Project C: Solar Clothes Dryer Deliverables: Physical scale model (1=1) 3D CAD model Thorough analysis of the operation and material and energy balances, and A complete description of the design and its development.

    42. Project D: Daylighting Leads to health and productivity Offsets electric lighting Challenging due to variability in intensity and direction of sunlight

    43. Daylighting Tradeoffs Natural light is let in with windows and skylights, using less electricity for light

    44. Project D: Daylighting Deliverables: Research into effective techniques for daylighting, Experimentation with scale models, Analysis with spreadsheets and other software, 3D CAD model, Comprehensive final report.
