1
Name of Building(s) or Project Speaker(s) Organization(s)
2
Project Name When building was built Type of construction Typical usage (classroom, office, computer, lab, etc.) Number of floors, buildings, and square footage Time of usage (ex.9am-5pm) <--picture of the outside of the building
3
Project Name Original HVAC and Lighting Equipment Describe original chiller(s) cooling tower(s) –size, number of cooling towers, efficiency, refrigerant, capacity, etc. Describe heating system, fuel used Electricity, gas, or steam for heating and cooling Number of chillers and/or cooling towers Any centralized control systems, air handling units, etc. Type of lighting or lamps, type of ballasts
4
Project Name Original Electricity Demand and Use Add bar chart of one year of electricity consumption by month (month vs. kWh) –Based on information available, the electricity consumption can be divided into: –peak and off-peak bars –cooling and non-cooling consumption –heating and cooling –heating, cooling, auxillary HVAC, lighting Bar chart of electricity demand by month (month vs. kWh)
5
Project Name Electricity End-Uses A pie chart of electricity end-uses clarifies where use is greatest, with the total annual electric consumption and utility costs broken up into heating, cooling, fans, lighting, any other metered, equipment and miscellaneous
6
Project Name Original Natural Gas Use Bar chart of one year of natural gas consumption (months vs. therms)
7
Project Name Project Scenario Why was the retrofit done? What building problems needed to be addressed? Old, inefficient systems Lack of cooling capacity Expensive maintenance High energy consumption Rising cost of electricity, steam, or other fuels Unreliable, unsafe equipment Equipment failure Meet code regulations Building modifications Rebates offered
8
Project Name Project Challenges What guidelines had to be met? Strict financial budget Electricity usage goal in kW/ft 2 To be a model for sustainability Keeping building operational during the retrofit Reduce peak electricity demands Eliminate CFC’s Time and space constraints
9
Project Name Other Project Challenges Other project guidelines Persuading decision makers to approve Finding project financing Modeling energy efficiency measures Procurement of equipment Dealing with low-bid contractors
10
Project Name System Solutions Brief list of energy improvements Chillers (replaced or retrofitted) Cooling system improvements Delivery system improvements Load reductions Other building improvements
11
Project Name Chiller Replacement or Retrofit New or upgraded chillers efficiency refrigerant size fuel type energy savings other details Optional chiller picture-->
12
Project Name Cooling & Delivery System Improvements Describe any cooling or delivery system changes New cooling towers Variable speed motors & drives New piping scheme Reduced supply air & outside air Use of free cooling Variable air volume boxes New EMCS or direct digital controls Other changes
13
Project Name Lighting Improvements Replaced existing lighting –T-8 fluorescents, electronic ballasts –compact fluorescents –LED fixtures on exit signs Occupancy sensors used to turn off lights Increased use of daylighting Separate fixtures for task & general lighting Light levels maintained or improved New W/ft 2, energy savings
14
Project Name Other Building Load Reductions Added insulation to walls or ceiling Efficient appliances –EnergyStar computers, copiers, faxes, etc. Occupancy sensors tied in to HVAC system Window improvements –New low emissivity dual glazing windows –Window films Cool white roof coating used
15
Project Name Other Significant Changes Describe details of the change Improved efficiency Energy and monetary savings
16
Project Name Post-Retrofit Utility Use Bar chart of current gas, steam, and/or electricity usage (energy vs. month) Monetary energy savings
17
Project Name Integrated Economics (Sample) Measures with lower paybacks reduce the overall project payback period
18
Project Name Financing Structure List the various sources of financing Any rebates or grants used Energy service contracting terms Self-funding Interest rate & payment period Was payment schedule adjusted to provide positive cash flow from energy savings?
19
Project Name Project Timeline
20
Project Name Project Results Annual utility savings Cost of retrofit project Overall payback period Reductions in maintenance or operating costs
21
Project Name More Project Results Building problems addressed & solved Improved air quality, lighting, etc. Increased worker productivity Improved tenant/building comfort Reduced dependence on CFC’s
