Kendal at Oberlin Energy Conservation & Sustainability Initiatives

Recap of Kendal at Oberlin’s Energy Conservation & Sustainability Initiatives The original Campus Development Overview of the Energy/Sustainability Initiatives The Sustainability Features built into the New Units There is more work to be accomplished – The “Greening” of Kendal!!

Original Campus included a Wetland’s Mitigation Plan –Site Design Features –Creation of Lakes

Building Envelope Insulation Value of Cottages

The orientation of the existing units and the Covered Walkway System Accomplished strong Solar Shading results!

Engaged Northeastern Energy Concepts Project Completed in 1997 with Follow Up in 1999 Scope of Project Included: –Energy Consumption Patterns –Recommended an Energy Conservation Program –Capital Investments Made

Accelerated Measures Standard Measures Custom Measures Operations & Maintenance Recommendations

Replace Resident Shower Heads Replace Water Closets Rewire Existing Apartment Switch with Heating & Cooling Mode Only

Install a New Power Meter or Recorder Request the Power Company provide KW demand peaks on monthly bills

Install Entel System Upgrade Main Chiller panels Install Power Conditioning Units

Rebalance all HVAC Systems Upgrade and Balancing of the Air Conditioning System Fans Residential & Common Area Lighting Upgrade

Establish an Energy Subcommittee of the Board Maintain a Preventative Maintenance Program Update Drawings to reflect system changes and modifications

Central Chilled Water Pump & Piping Upgrade Chilled Water System Balancing Valve Upgrade Premium Motor & VSD Drive Upgrades

Install the Entel Control System in the Common Areas Install a System to capture the Rejected Heat

Lighting Program Included: –NEC Findings –A Partial Lighting Upgrade was completed –Light Tubes Installed

Water Usage Program: –Irrigation System on a separate meter –Use of pond water for plant watering –Water bags used for tree maintenance –Well drilled to create water flow on Heiser Circle Pond

Recycle/Refuse Program: –Recycle Program Established: Paper, Aluminum, Batteries, Plastics –Benefit to Oberlin Schools –Cooking Oil from Kitchen provided to Bio Program in Oberlin

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

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 Investment in Wetland Areas: –Major improvement in the Heiser Circle Wetland area –Formal Review & Reporting Required

Engaged eQuest to complete –High Performance Building Analysis –Make a Recommendation to Upgrade the Energy Performance of the existing Cottages

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

Standard Measurement Tools to Evaluate different Options: –Simple Payback Period –The Return on Investment Percentage “ROI” –Life Cycle Payback Period

The Base Model represents: –The original building as designed and constructed –Used to Compare with Other Models

Increase the Insulation Value Upgrading of Air Conditioning Units External Solar Shading was not considered necessary

Consider replacing HVAC System Would a Geothermal System be Cost Effective?

The Combination of certain Energy Options that is: –Cost Effective –Improves Energy Efficiency –Utilizes Existing Infrastructure whenever possible

Optimum Alternative – The High Performance Model Includes: –Combination Air-to- Air Heat Pump & –Energy Recovery Ventilator with –Additional Attic Insulation

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

The High Performance Model requires: –Capital Investment of $21,000 for a 4 unit cluster –Total Capital Investment for all Cottages = $756,000

Conduct a “Field Test” the results of the report The Energy Conservation Pilot Project

Kendal at Oberlin Environmental & Sustainability Features Phase I New Units

Site Considerations: –Site Design –Storm Water & Wetlands –Site Lighting & Walkway Lighting –Solar Powered Fixtures –Landscaping

Building Envelope: –Framing & Insulation –Entrance Doors –Windows & Patio Doors

Building Envelope (Continued): –Day Lighting –Overhangs

Mechanical & Electrical Systems: –Natural Ventilation –Ceiling Fans –Air-to-Air heat pump with auxiliary electric heaters installed –Domestic Hot Water –Water Efficiency

Materials & Finishes: –Paint, Sealants and Adhesives –Flooring

LEED Certification Process: –This Process was evaluated by the Master Planning Committee –The New Units would have met the Minimum LEED Certification Level

You Can Make a Difference in Your Cottage: -Reduce -Reuse -Recycle

“Bright Ideas” can make a Difference: –Participate in the “Light Bulb Exchange Program” –Turn Lights off in your home when not in use –Utilize Natural Lighting When Possible
