Inventory and Benchmark:
From Wiki
How to Conduct an Inventory
Contents |
[edit] Preliminary Data
Gather at least one years worth of energy bills
This includes both electricity and heating bills (if they are separate)
This also includes what type of fuel is used for the heating system
[edit] Measure
Find out the buildings square footage (sq/ft), as well as roughly how much of the building is receiving heat.
Determine how many hours in the week the building is operating for and the average number of occupants during that time.
[edit] Visit
Walk the site - everywhere - and take pictures of everything.
[edit] Benchmark
[edit] Definition
“A point of reference from which measurements may be made.”
Compare point to other buildings. Baseline for assessing improvements. Organizing tool for own facilities.

[edit] Types of Documents you will need
Buildings For EACH building that is owned/operated by the municipality (including police, fire department, highway/transportation department, water/sewer works, library, town administrative buildings, municipal parks, and any other municipally-owned facility; NOT including public schools), you will need:
- Electricity bills for each month of 2005 (may include either some days of Dec. 2004 or some days of Jan. 2006). The bills must show the cost and kwh of electricity used in the billing cycle (kwh often recorded on second page). PLEASE NOTE: record on the data sheet the TOTAL cost of the electricity bill for each month (not just the cost for kilowatt hours used).
- Heating fuel bills for each month (or delivery) for 2005 with cost, units of fuel, fuel type, and approximate date of delivery.
- A building manifest or tax record that shows square footage of building space, year built/updated, and percentage space heated/cooled/electrified. If there are no documents such as these, you can ask the town administrator or secretary how to obtain this information.
Streetlights
- Electricity bills for 2005 that show the number of streetlights in the town, cost of lighting, and kwh used (need each month to get a sum of all costs and kwh used over the year).
Vehicles
- List of vehicles owned/operated by the town that shows what types of vehicles they are (car, truck, large truck).
- Any records kept on the use of the vehicles: gallons of fuel used, cost of fuel, odometer readings that show how many miles they traveled over the year 2005.
Water/Sewer
- Electricity bills showing the overall yearly cost of operating municipal pumps and water treatment facilities.
- Any documents describing the number and types of water facilities operated by the municipality.
- Records of gallons of water pumped or treated.
- If all water is managed through individual wells and septic systems, the above data is not needed.
Waste
- Any records of the haulage and tipping costs of waste removal FOR MUNICIPAL OPERATIONS only (do not include residential, commercial or industrial waste data).
- Any records of total tons of waste removed for municipal operation.
- Breakdown of waste types, if available.
The Town Annual Report for 2005 may be helpful for filling in some of the data you are collecting.
[edit] A Data Collection Checklist
This is an example data collection check list that can be used with town data. PM stands for EPA's free portfolio manager software, and ICLEI is the ICLEI software.
