Positive actual savings indicate utility costs have been reduced after adjusting for weather and other variables in dollars. balance point (HtgDD), the outdoor temperature below which space heating is required or (C1gDD), the outdoor temperature above which space cooling is required. baseline The adjusted, tuned pre -retrofit bills (usually 1 year) used to compare, to post -installation usage in order to calculate savings. baseline cost Cost calculated for the baseline using current rates. billed dollars Amount billed from utility company. bill matching Adjustment made by MetriN m .to account for differing number of days in the billing period before calculating cost avoidance. cost avoidance The difference between the baseline cost and the actual or SimActual cost in dollars. degree-day Unit representing one degree of difference between the balance point selected and the average temperature during one day. EER Energy Efficiency Ratio of cooling equipment defined as the cooling effect in BTU's divided by the power use in watts guarantee period Time period specified in contract for which Honeywell will guarantee energy savings. guarantee year Number identifying for which year the review is performed based on the number of years the guarantee is in effect. guaranteed savings Those savings Honeywell promises the customer through the use of maintenance programs, retrofits, upgrades and energy management systems. Year 3 Cost Avoidance Report, City of Cincinnati PII 5.9 Glossary of Terms HVAC Industry standard abbreviation for Heating, Ventilating and Air Conditioning. HtgDD/C1gDD HtgDD = Heating degree-days ClgDD = Cooling degree-days kW Kilowatt - a unit of electrical power, equal to 1000 watts. kWh Kilowatt hours - a unit of electrical energy or work, equal to that done by one kilowatt acting for one hour. modification An allowance for changes in the facility which affect utility usage that occur while tracking the performance of a meter. Modifications correct both the actual and baseline usage and cost for meters. pre -installation Time period (start month and stop month, typically one year's time) that is used as a benchmark for comparison which consists of all energy bills applicable to the retrofit. RZ A measure of how well the independent variable in a regression can explain changes in the dependent variable. An R2 = " l .0,, indicates a perfect correlation. rate tariff Actual amount the utility company charges per unit of energy or demand; used by MetrixTM to calculate utility costs for the SimActual & Baseline scenarios, reference year The actual usage for designated baseline period. review period Time period for which savings are reported. runtime adjustment Adjustment made for those hours equipment has run beyond the operating hours specified in the contract. simactual The total cost for the billing period as calculated by MetrixTM weather adjustment Adjustment made by MetrixTM for weather variations using degree days.

This program funded a $3,275,500 investment plus $585,592 in a change order that addressed energy improvements, deferred maintenance, and operational enhancements. The project is expected to save $336,053 annually in utility and operational savings over the ten year term of the agreement. This Post Installation Conditions Report (PICR) has been prepared to document a successful transition from the construction period to the guarantee period for work performed at Monroe County. The installation savings for this period is $263,346. Option A Savings Option C Utility Savings $ 189,472 $ 36,915 Rebate Savings $ 36,959 Total Cost Avoidance $ 263;346 All work was completed and accepted by the County on May 25, 2017 as referenced in the Final Acceptance Certificate. Based on this acceptance date, the energy guarantee start date for the project began on .Tune 1, 2017 and will be in effect for 3 years. On behalf of Honeywell, we look forward to working with you and ensuring your savings are sustainable.

Adjustment Calculations used to bring energy usage in base year to the same set of conditions as the current year. Balance Point Temperature (BPT) For heating degree-days, the outdoor temperature below which space heating is required; for cooling degree-days, the outdoor temperature above which space cooling is required. This is typically 65 degrees, but varies based on building type, construction material, etc. Baseline The raw base year data adjusted by the energy impact of the variables between the years being compared. BTU British thermal unit; the quantity of heat required to raise the temperature of one pound of water by one degree Fahrenheit. BTUh The quantity of heat generated/consumed over a one hour period. CDD Cooling Degree -Day; a value that represents weather condition severity. It is the monthly sum of the daily mean temperature (measured by the National Weather Service) above the cooling Balance Point. Cost Avoidance The difference between the actual cost incurred during a selected time period versus what the cost would have been had the cost avoidance strategy not been implemented. ECM The Energy Conservation Measure (ECM) is the installation of equipment or systems, or modification of equipment or systems, for the purpose of reducing utility (energy, water, etc.) consumption, demand and costs and/or non -utility (O&M, operational) costs. EMS Energy Management System; a computer that can be programmed to control and/or monitor the operations of energy -consuming equipment in a facility. Guarantee Period The period beginning on the first (Ist) day of the First Guarantee Year and ending on the last day of the final Guarantee Year. Also known as the "Measurement and Verification Phase" or "Performance Period". Guarantee Year The First Guarantee Year and each of the successive twelve (12) month periods commencing on the anniversary of the commencement of the First Guarantee Year throughout the tern of the agreement. Guaranteed Savings The amount of avoided Energy and Operational Costs necessary to pay for the cost of the Work and Support Services incurred by the customer in each Guarantee Year. HDD Heating Degree -Day; a value that represents weather condition severity. It is the monthly sum of the daily mean temperature (measured by the National Weather Service) below the heating Balance Point. 5.2 Glossary Of Terms HVAC Industry standard abbreviation for Pleating, Ventilating and Air Conditioning. kW Kilowatt; a unit of electrical power, equal to 1000 watts. kWh Kilowatt hours; a unit of electrical energy or work, equal to that done by one kilowatt acting for one hour. Load Factor The percentage of time that a piece of equipment operates at full toad over a measured time period. (i.e. Lights that are operated at 100% Load Factor. Refrigerators, on the other hand, operate at less than 100% load based on internal and external temperatures while also cycling on & off as needed to maintain a temperature set point.) M&V Measurement and verification; the.process of determining savings using one of the four IPMVP options. MCF An industry standard measure of a gaseous fuel, typically natural gas, having volume of 1,000 cubic feet. (See also, Decatherm) Operational Cost Avoidance Often referred to as O&M cost avoidance, this includes the avoided costs of operating and maintaining the facilities, such as, but not limited to, the avoided cost of inside and outside labor to repair and maintain affected systems and equipment, the avoided cost of custodial supplies, the avoided cost of replacement parts, the avoided cost of deferred maintenance, the avoided cost of lamp and ballast disposal, and the avoided cost of new capital equipment. Plug Load Electrical energy -consuming equipment that draws its operating power through cords and wall plugs. (i.e. Office equipment, refrigerators, freezers, vending equipment, radios, TVs, microwave ovens, coffee pots, fans, floor heaters, etc.) Post -Retrofit Period Any period of time following commissioning of the ECMs. Reference Year A period of time (usually one year) which defines the baseline usage and is representative of the facility's operations, consumption, and usage that is used as the benchmark for determining cost avoidance. This is also referred to as the "Base Year" Therm The energy content of a 100 cubic feet volume of a gaseous fuel; sometimes used as a synonymous term for CCF. Technically, however, a therm is the Btu heat content of 100 cubic feet of a gaseous fuel, where the Btu content varies based on source and quality. 5.3 7m em T I 01 IL IF It ";,- VLP _iiii I Oil- r A .
