•Purchasing Practices include:
–Energy Star Rated Appliances–Replacing Fixtures with Low Water Use Fixtures–Installation of Ceiling Fans–Implementation of Dimming Ballasts to take advantage of Natural Day Lighting–Tankless Water Heater installed in the Pool Locker Room area
Additional Sustainability Additional Sustainability InitiativesInitiatives
•Landscape Management Plan & Practice:–Composting Space Provided–Adding Trees to the Campus–Use of Natural Landscaping –Using Environmentally Preferred Products–Instituted “No Mowing” Days based on Ozone Levels
Additional Sustainability Additional Sustainability InitiativesInitiatives
•Additional Investment in Wetland Areas:–Major improvement in the Heiser Circle Wetland area–Formal Review & Reporting Required

Scope of the ProjectScope of the Project•Engaged eQuest to complete –High Performance Building Analysis–Make a Recommendation to Upgrade the Energy Performance of the existing Cottages
Scope of the ProjectScope of the Project• Alternative Analysis Completed
including:– Increasing the Level of Insulation– External Shading Devices– High Efficiency Furnace & AC– Air-to-Air Heat Pump– Ground Source Heat Pump– Energy Recovery Ventilator– 2 Different High Performance
Alternatives were considered
What We LearnedWhat We Learned From the Project From the Project
•Standard Measurement Tools to Evaluate different Options:–Simple Payback Period–The Return on Investment Percentage “ROI”–Life Cycle Payback Period
What We LearnedWhat We Learned From the Project From the Project
•The Base Model represents:–The original building as designed and constructed–Used to Compare with Other Models
What We LearnedWhat We Learned From the Project From the Project
•Increase the Insulation Value
•Upgrading of Air Conditioning Units
•External Solar Shading was not considered necessary
What We LearnedWhat We Learned From the Project From the Project
•Consider replacing HVAC System •Would a Geothermal System be Cost Effective?
What We LearnedWhat We Learned From the Project From the Project
• The Combination of certain Energy Options that is:– Cost Effective– Improves Energy Efficiency– Utilizes Existing Infrastructure
whenever possible
Recommendation Recommendation by eQuestby eQuest
•Optimum Alternative – The High Performance Model Includes:–Combination Air-to-Air Heat Pump &–Energy Recovery Ventilator with–Additional Attic Insulation
Recommendation Recommendation by eQuestby eQuest
•The High Performance Model results in (for the 4 Unit Cluster):–Reduction of Annual Energy Use by 17,670 kWH’s–Annual Energy Savings of $839–Reaches the Life Cycle Payback at 3.7 years
Recommendation Recommendation by eQuestby eQuest
•The High Performance Model requires:–Capital Investment of $21,000 for a 4 unit cluster–Total Capital Investment for all Cottages = $756,000
Next Steps for Future Next Steps for Future PlanningPlanning
•Conduct a “Field Test” the results of the report •The Energy Conservation Pilot Project
