Groups and Members
Solar Decathlon 2013 is a competition between 20 teams around the world to create the most innovative, energy efficient house.
Combine different engineering disciplines and Architecture to create an innovative, solar house.
Canopy house is aimed at providing sustainability for the older population to age comfortably.
Introduction
Canopy House
Diem Wall (backbone) Canopy like Solar Structure 18’ Solar Envelope 12’ Roof height
Floor Plan
Affordability Webinar Estimates need to be as accurate as possible Estimators will receive Project Manual upon
October 11th deadline No need to submit invoices as estimators use
RSMeans RSMeans
Offers cost data you can depend on Updated construction cost information
available in convenient book, CD, or online format
Take advantage of the RSMeans library (try and target product cost around these price estimates)
Affordability/RSMeans
Energy Star Appliances Easy identification for consumers
when purchasing Savings on energy bills without
sacrificing performance, features, and comfort
Reduce greenhouse gas emissions and other pollutants
Energy usage of the HVAC, Lighting, and Appliances Systems usage needs to be
determined in order to accommodate the number of solar panels used on the Canopy House
Energy Efficiency/Balance
Criteria for most appliances ADA compliant
Allows easy accessibility and use of all amenities in the house to people with disabilities
Uses as little water as possible Bosch Dishwasher uses 2.22 gal/cycle Bosch Washer uses 4,064 gal/year on average

Solar and Power
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.
Optimizing Panel Efficiency
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
Begun routing of black water systems
Corresponding with Architects about bed dimensions to source storage and waste tanks
Finalizing pump valve and back flow prevention locations
Hot Water Tank
Final selection based on capacity and energy consumption narrowed
Discussing with vendors potential donation
Determining whether a custom tank has to be produced
Phase Change Tank
Nominal heat capacity requirements being determined with results of sun drum output

HVAC Selection
Canopy House has chosen to utilize a Ductless Split System (DSS) Heat Pump with Energy Recovery Ventilator and Auxiliary Radiant Floor Heat
DSS benefits: high efficiency ratings, multiple zones, Variable Speed Compressors & Fans, reduced energy consumption
Radiant Floor Heat benefits: constant & stable temperatures, multiple zones, utilizes free energy
Disadvantages of both: complex mechanical systems
Ductless Split Systems
Selection Based on Mitsubishi products: Wall-Mount & Cassette style
Features: Redlink embedded controls for home integration, i-See infrared sensor, directional vanes, multi-zone, and wireless remote
Wall-Mount utilizes the i-See sensor technology Cassette style allows for use of Energy Recovery Ventilator
i-See Sensor & Directional Vanes
Energy Recovery Ventilator
• Reduces energy costs as well as heating and cooling loads• Allows for scaling down of equipment and air-side
economizing• Helps maintain a desirable humidity of 40-50%
Hot Water Radiant Floor Heat
Typical systems include a hot water generator (boiler, hot water heater, solar hot water heater, etc.), a pump, zone valves, piping, and controls
Piping is commonly placed beneath the finished floor, in a concrete slab, or the underside of the sub-flooring
Passive floor heating system that uses “free” energy for heating purposes
Collected heat is incorporated from the SunDrum, solar water heating system, by a heat exchanging tank utilizing
Phase Changing Material (PCM)
Typical System Design Incorporated into the SunDrum solar
water heating system by heat exchanging tank system
Incorporates Phase Change Material (PCM) – Research in Progress
System utilizes all stored “free” energy for radiant floor heat system before initializing the Ductless Split System units
With proper sizing and load calculations, this system should allow for an estimated 50% reduction in heating energy requirements
Disadvantage of System: Effective only for periods of heating, with no cooling capabilities
