by eQuest, Incby eQuest, Inc.

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
