Name of Building(s) or Project

Speaker(s)

Organization(s)

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

Project NameOriginal 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

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)

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

Project NameOriginal Natural Gas Use

• Bar chart of one year of natural gas consumption (months vs. therms)

Project NameProject 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

Project NameProject Challenges

• What guidelines had to be met? • Strict financial budget• Electricity usage goal in kW/ft2

• To be a model for sustainability• Keeping building operational during the retrofit• Reduce peak electricity demands• Eliminate CFC’s• Time and space constraints

Project NameOther 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

Project Name System Solutions

• Brief list of energy improvements• Chillers (replaced or retrofitted)• Cooling system improvements• Delivery system improvements• Load reductions• Other building improvements

Project NameChiller Replacement or Retrofit

• New or upgraded chillers• efficiency• refrigerant • size• fuel type• energy savings• other details

• Optional chiller picture-->

Project NameCooling & 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

Project NameLighting 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/ft2, energy savings

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

Project NameOther Significant Changes

• Describe details of the change• Improved efficiency • Energy and monetary savings

Project NamePost-Retrofit Utility Use

• Bar chart of current gas, steam, and/or electricity usage (energy vs. month)

• Monetary energy savings
