Solar Decathlon Team Tidewater 2013 ODU Engineers
Groups and Members • Project • Horace Woolard • Wesley Riley • Solar • Jessica Purdin • Morgan Sherrill • Eric Bagho • Mark Evans (Webmaster and Scheduling) • Gaming/Strategy • Graeme Melrose • Michael O’Toole • Water • Herbert Johnson • Nathan Howell • HVAC • Todd Spreeman • Chris Dohse • Andrew Pakla
Introduction • Solar Decathlon 2013 is a competition between 20 teams around the world to create the most innovative, energy efficient house. • Combines different Engineering disciplines and Architecture to create a sustainable, solar house. • Canopy House is aimed to allow individuals to age comfortably, while maintaining an independent lifestyle.
Capy House • Design inspired by forest • Canopy like Solar Structure • Diem Wall (backbone)
Affordability/RSMeans • Affordability Webinar • Estimators will review Project Manual • 3-4 weeks • Upon return, we have 2 weeks to fix any problems • Estimators use RSMeans • RSMeans • Offers updated construction cost data • Targeted product cost around current price estimates
Residential Equipment • Appliances • Energy Star compliant • Savings on energy bills without sacrificing performance, features, and comfort • ADA compliant • Easy use and accessibility to people with disabilities • Electric • Minimal water consumption due to subcontest testing • 2-3 kWh/day combined energy consumption
Solar and Power • Bosch Solar Module c-Si M 60 (Monocrystalline) • SolarMount Evolution (Unirac)
Optimizing Panel Efficiency • Enphase M215- MICRO INVERTER -24/7 monitoring and analysis, DC to AC power conversion for every individual panel • SunDrum- Captures the solar panel’s wasted heat and converts the heat into hot water and electricity. In addition, this process cools the panels allowing them to operate more efficiently.
Solar and Power Deliverables • Configure optimal orientation for all solar panels • Complete 3 Part Master Spec for every component • Complete Installation Manuel • Complete Documentation for all components (Revit) • Test the performance of the system to determine optimal number of panels required
Plumbing • Completed routing of all domestic water systems • Configured Water Storage and Disposal System • Finalized pump valve and back flow prevention locations
Hot Water Heater • Final selection based on capacity and energy consumption • Discussing with vendors potential donation
Phase Change Tank • Nominal heat capacity requirements being determined with results of sun drum output • Custom manufacturing requirements being determined
HVAC Selection • Ductless Split System (DSS) Heat Pump • Energy Recovery Ventilator • Auxiliary Radiant Floor Heat • DSS benefits: Efficiency, Zoning, Low Energy Usage • Radiant Floor Heat benefits: Stable temperatures & Zoning • Disadvantages: Complex mechanical systems
Ductless Split Systems i-See Sensor & Directional Vanes • Mitsubishi products: Wall-Mount & Cassette style • Multi-Zone Capability • Redlink control • i-See sensor and wireless remote • Directional Air Flow • Cassette Unit & Energy Recovery Ventilator
Energy Recovery Ventilator • Reduced energy costs & HVAC loads • Scaling down of equipment and air-side economizing • Maintains humidity at 40-50% • Control of Carbon Dioxide levels
Hot Water Radiant Floor Heat • Typical System: Hot Water Source, Pump, Zone Valves, Piping, and Controls • Canopy House System: SunDrum & Phase Changing Material • Passive system: Utilizes “Free” Energy • Secondary Heat Source
Canopy House System • Advantage: Estimated 50% reduction in heat load • Disadvantage: Effective only for heating, no cooling capabilities
