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

Determining the volume of PCM to store energy

Researching prefabricated jacked tanks vs custom manufacture

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
