Section A: Overview Honeywell is excited to partner with the City of Easthampton (City) as your Energy Services Company (ESCO) to develop a comprehensive energy savings and infrastructure renewal program through performance-based contracting. The Investment Grade Audit (IGA) agreement between the City and Honeywell outlines the scope of work, process steps and timeline required to complete and present the final IGA. This Preliminary Audit Analysis (PAA) was developed for the City according to the requirements of the Investment Grade Audit Services Agreement (Agreement) between the City and the Honeywell Energy Services Group (Honeywell). The IGA Agreement defines the deliverables of the PAA as follows: Complete list of all potential energy and water conservation opportunities;
Identify energy and water conservation measures that seem likely to be cost effective and therefore warrant detailed analysis;
For each energy and water conservation measure, prepare a preliminary estimate of energy or water cost savings by identifying the typical simple payback range.
The PAA is the first of three major deliverables required by the Agreement. The goal of the PAA is to provide a list of potential Energy Conservation Measures (ECMs), identify the most cost-effective ECMs for further analysis, and present a preliminary estimate of typical simple payback ranges for the ECMs. The ECM types are organized in Technical Categories related by technology or function, promoting a common reference by building and general definition. With this PAA in hand, the City and Honeywell will work together to agree on a subset of ECMs which will be the basis for the Draft Technical Energy Audit Report (DTEAR), the next major deliverable. Upon completion of the DTEAR, the City and Honeywell will review and select the final list of ECMs to be included in the final major deliverable, the Optimize IGA phase. At the completion of the Optimize IGA phase Honeywell will present a final IGA report to the City. The final IGA represents the optimized project, which is the basis for the Energy Management Services Agreement (EMSA) contract for the implementation of the final ECMs.
IGA Contract Steps and Milestone Goals Key steps and target milestone goals to achieve major deliverables as reviewed and discussed with the City include: Weekly joint progress meetings;
Monthly reporting to joint executive leadership teams;

Summary of Preliminary Audit Analysis – Our Findings
Honeywell has identified the potential to reduce annual energy and water costs by approximately 11.2% per year, or an estimated $50,420 in annual energy and water savings based on the list of facilities included in the IGA Agreement. Honeywell estimates that the energy and water savings, coupled with potential solar energy generation opportunities, projected utility rebates, and CARES funding contribution will support a 20-year self-funded performance-based contracting project of $4,611,022 to be used for upgrades to City facilities. Assumptions used in this estimate along with the general calculation are as follows:
Total Annual Energy & Water Savings $50,420
Total Annual Solar Generation Value1 $160,337
Total Utility Incentives2 $95,889
Total CARES Funding Contribution3 $300,000
Project Term 20 Years
Potential Performance-Based Contracting Project Size $4,611,022 1Generation value based on approximate unblended rate on a facility-by-facility basis (~ $0.12/kWh on average) 2Incentives are subject to change based on funding availability and will need in-depth analysis and review to finalize, estimate based on current custom program offerings provided by the utility ($0.325/kWh and $2.00/Therm) 3Approximate amount available based on initial discussions with the City
Potential Performance-Based Contracting Project Size = (Total Annual Energy & Water Savings + Total Annual Solar Generation Value) × Project Term + Total Utility Incentives + Total CARES Funding Contribution
Further, our experience reflects that the proposed ECMs will improve employee, student and visitor comfort, and increase the reliability of the mechanical and electrical systems within the IGA facilities. The upgrades will also augment the City’s existing programs by enhancing innovation, promoting community engagement and learning, and by providing technical and financial programs to reduce energy consumption (or use) and Greenhouse Gas (GHG) emissions ahead of Climate Action Plan goals. Key Benefits to the City
Provides $4,611,022 in capital infrastructure investment, without any upfront payments or additional capital cost;
Reduces municipal carbon emissions in IGA facilities by 268 Tons per year or 14.2% of the proposed baseline period emissions;
Takes advantage of 3rd party utility incentives and rebates, excluding the potential for grants and renewable or alternative energy credits;
Frees-up City capital for other critical priorities, avoiding or offsetting future capital cost requirements for equipment and infrastructure nearing the end of its useful life;
Supports a long-term cultural focus on energy efficiency by employees, students and visitors;
Improves mission reliability of critical City facilities such the Public Safety Complex, Water Department, and Wastewater Plant through the installation of new equipment and infrastructure;
Minimizes long-term exposure to volatile energy costs by reducing energy consumption;
Reduces energy use and greenhouse gas (GHG) emissions ahead of the City’s Climate Action Plan goals;
Enhances current Operations & Maintenance (O&M) programs and procedures; and
Offsets project costs with Honeywell’s first-party annual energy savings guarantee.

PAA Development Approach
As noted, the intent of the PAA is to:
List all potential ECM opportunities;
Identify ECMs that seem likely to be cost effective and warrant a detailed analysis; and
Prepare a preliminary estimate of energy and water cost savings to include a simple payback range. PAA development included the following steps:
Identification of all potential ECM opportunities based on Honeywell’s experience and the findings of the preliminary surveys of the selected IGA facilities;
Review the past thirty-six (36) months of utility data for the IGA facilities to establish a baseline;
Perform a detailed benchmarking analysis to determine potential cost savings;
Identify simple payback ranges by ECM using the benchmarking analysis and Honeywell’s history of implementing these ECMs.
Identification of all potential ECM opportunities based on Honeywell’s experience and the findings of the preliminary surveys of select IGA facilities
Honeywell Solution Development Engineers (SDE) performed preliminary facility surveys at each of the selected locations. The surveys included interviews with City personnel that had specific knowledge of the facilities, energy systems, operations and maintenance practices. Based on observed field conditions and problem areas identified, a list of potential ECMs to be considered was developed for each facility. In the next report iteration, a detailed Existing Conditions Report (ECR) will be presented for each facility to fully describe the existing conditions of all major systems.

Review of the most recent thirty-six (36) months of utility data for the IGA facilities to establish a baseline:
The IGA Agreement requires the ESCO to establish base year consumption for electricity, natural gas, fuel oil, and water by examining utility data over the past thirty-six (36) months. Honeywell performed a detailed analysis of the utility data provided by the City for Calendar Years (CY) 2017, 2018, 2019 for electric, natural gas and fuel oil, and 2018, 2019 and 2020 for water. This analysis is based on annual total energy and water use and cost by utility source for each facility included in the IGA Agreement. The data was extracted from utility summary data provided by the City for each account. Reasonable estimations were included where required to ensure a complete baseline dataset. During the DTEAR and Optimized IGA phases, a monthly utility bill analysis, including commodity, demand, and transportation charges will be performed for each included facility. For detailed information on annual energy, water, cost and consumption by facility please see Appendix 2. The following trends were noted when comparing the summary utility data provided for the six (6) included facilities during the period of CY2017 to CY2020: The consumption and costs for electric and natural gas have held relatively stable over the time period
included in this analysis;
o Electric consumption increased 9.9% between CY2017 and CY2018, and subsequently decreased 0.9% in CY2019;
o Natural gas consumption increased 6.2% between CY2017 and CY2018, and subsequently decreased 7.9% in CY2019;
The consumption and costs for fuel oil experienced more dramatic swings year over year however, the impact is relatively insignificant as this is by far the least cost intensive utility and can be influenced by storage capabilities;
o Fuel oil consumption decreased 72.2% between CY2017 and CY2018, and subsequently increased 221.9% in CY2019;
Water consumption is the most volatile utility with consumption decreasing sharply over the time period included in this analysis; o Water consumption decreased 56.2% between CY2018 and CY2019; o Water consumption for CY2020 was not included in the analysis as it appears to be heavily
impacted by occupancy changes due to COVID-19; o This large swing in water consumption will be evaluated further during the next phase of project
development Energy and water usage, and costs for this period are summarized in the tables and figures below.

As shown above, energy and water consumption and cost vary year-to-year. This variation can be attributed to many factors including changes in occupancy, weather, usage, building area, mechanical, and electrical system. Baseline consumption, or base use, is used to identify the amount of energy and water a facility would use if the ECMs were not implemented. Baseline consumption and baseline energy rates are used to calculate the baseline costs for energy or water use. In general, energy and water cost savings associated with an ECM are calculated as follows:
Baseline Cost = Baseline Consumption × Baseline Energy or Water Rate
Post ECM Installation Cost = Post-Installation Consumption × Contract Energy or Water Rate
ECM Energy Savings = Baseline Cost – Post ECM Installation Energy Cost
As noted previously, the IGA Agreement requires that the ESCO establish baseline consumption by examining utility bills (electricity, gas, oil, steam, water, etc.) for the previous 36 months. Consistent with this requirement, Honeywell performed an analysis of the utility data provided by the City for CYs 2017 through 2020. Based on this analysis, Honeywell recommends that an average of the usage and cost for the three-calendar years (CY2017 – CY2019) for electric, natural gas, and fuel oil be used as the baseline to account for variations in energy consumption and costs. For water it is believed the last year of data provided was heavily impacted by COVID-19 related changes in building population, thus a two-calendar year average (CY2018-CY2019) of water cost and consumption is recommended.

Total $36,681 $11,160 $2,579 $50,420 $451,347 11.2% In order to estimate preliminary energy and water cost savings, Honeywell determined the Energy Use Intensity (EUI) for our preliminary analysis. EUI is a benchmark that expresses a building’s energy use as a function of building size. A low EUI is considered more energy efficient, and conversely, a high EUI is considered less energy efficient. EUI is calculated by aggregating all building energy sources consumed in one year, divided by the total gross floor area. Values for electric and fuel energy consumption for all buildings are expressed in British Thermal Units per square foot (kBTU/ft2) When performing an analysis based on building EUI, a common benchmark comparison is the Commercial Buildings Energy Consumption Survey (CBECS). The CBECS, developed by the U.S. Energy Information Administration (EIA), is a “national sample survey that collects information on the stock of U.S. commercial buildings, including energy-related building characteristics and energy usage data (consumption and expenditures).” CBECS data is grouped regionally (New England States for example), and averages EUI data from buildings that have and have not been optimized through the implementation of ECMs. To identify and quantify opportunities for improvement, Honeywell has compared the City’s facilities with other similar facilities in the CBECS database. As described above, our analysis used an average of utility data provided by the City for CYs 2017 through 2019 for electric, natural gas and fuel oil. Facilities were classified according to principal activity (school, office, public order and safety, public assembly, etc.). Facility EUIs for electricity and fuel were analyzed, and a reduction goal assigned for each. Reduction goals were based on a comparison of current performance and the performance of similar facilities in the CBECS database. The reduction goal for each facility is based on its current EUI as compared to the CBECS database. Using this approach, a facility with an EUI in the median or lower quartile will have more potential for improvement than a facility that is in the upper quartile. Process based facilities, such as the Water Department and Wastewater Plant, have EUIs that vary greatly depending on the specific service offered. Because of this a reliable benchmark for facilities of this nature is not available in the CBECS database. Honeywell has conservatively estimated the potential savings for these facilities based on past project experience. The figure below shows the total EUI for the Municipal Building as compared to other Northeast office facilities in the CBECS database. The existing EUI of 92.84 kBTU/ft2 is right around the lower quartile of performance for this building type subset, which means there is significant room for improvement and a more aggressive savings potential is targeted. The conditions observed during the preliminary survey and the age of this facility support this savings potential.

The next figure shows the total EUI for Easthampton High School as compared to other Northeast high school facilities in the CBECS database. The existing EUI of 41.97 kBTU/ft2 is amongst the top energy performers for this building type subset, which means there is little room for improvement and a more conservative savings potential is targeted. Given the findings of the preliminary survey, the age of this facility (less than 10 years old), and its use of renewable solar energy, these results fall inline with expectations.
Based on the approach described above, a custom analysis was performed to compare the existing and expected post-retrofit energy usage by facility. Water savings were conservatively estimated based on the findings of the preliminary audits based on historical performance in other performance contracting projects. The proposed savings associated with water conservation measures are achieved by reducing water and sewer use. Facility-by-facility benchmark analysis and savings calculations are included in Appendix 3.

Payback ranges will vary based upon utility rates, operating and maintenance conditions, use of negotiable payment streams, and the availability of rebates and incentives. 3Equipment service life expectancy shown are average values; actual equipment service life will vary depending on the installed technology and regular maintenance activities performed (Source - 2011 ASHRAE Applications Handbook, Table 4 – Comparison of Service Life Estimates).
Conclusion This preliminary analysis conducted by Honeywell has identified that there is an opportunity for the City to leverage energy savings to support a self-funded, comprehensive, infrastructure renewal program through performance-based contracting. The benefits to the City associated with moving forward with this program include the potential to:
Decrease energy consumption and cost by repairing, upgrading, or replacing old and inefficient facility systems;
Increase occupant comfort and safety by increasing lighting levels, upgrading temperature control systems and equipment, and addressing ventilation deficiencies;
Reduce operational and maintenance costs by replacing old and failing systems with new systems;
Reduce the need for capital investment in building systems by replacing failed and ageing electrical and mechanical systems.
Based on a bundled (or combined) ECM approach, we are confident, due to this PAA, that the City has an opportunity to reduce energy and water costs, lower carbon emissions and self-fund critical deferred maintenance needs. As highlighted, the PAA has identified an opportunity to reduce baseline energy and water use by 11.2%, saving the City $50,420 annually in energy and water costs. Assuming a 20-year project term, the $50,420 in annual savings, with potential solar generation, projected utility rebates and CARES funding contribution, will self-fund $4,611,022 in capital upgrades to the IGA facilities. In addition to the $50,420 in annual demand side savings opportunities, Honeywell believes there is also an opportunity to secure lower energy supply costs by implementing renewable energy solutions, such as solar PV at select City facilities and locations. With these factors considered, the financial benefits of this program could improve significantly beyond the 11.2% in annual cost savings when combined with energy supply side savings, associated 3rd party grants, and available renewable or alternative energy credits.

A detailed discussion with the City is required to determine potential solar PV installation locations, the status of current agreements with local solar farms, and any plans to renew these agreements or purchase equipment after contract terms expire.
Recommendation Honeywell advises that all ECMs identified in the Recommended ECM Matrix table above, be further developed as part of the DTEAR phase for the selected IGA facilities. During the DTEAR phase the following will be performed for each facility: Perform detailed inspections;
Document existing conditions;
Develop current facility requirements;
Perform occupant interviews, conduct surveys, and install data logging equipment as necessary to confirm building system and occupancy schedules;
Perform a detailed utility analysis including 36 months of utility billing data for each utility and meter;
Establish baseline utility consumption and cost;
Develop a preliminary list of energy and water savings ECMs by facility;
Develop preliminary pricing, annual saving, O&M and M&V requirement, and third-party funding for ECMs by facility; and
Provide a DTEAR as required by the IGA Agreement. Honeywell anticipates completing the IGA following the milestone dates outlined previously. These dates include the delivery of the DTEAR by March 12th, 2021 and an executed EMSA by May 21st, 2021. We look forward to working with the City to review this report and discuss next steps in project development.

2. Annual Energy and Water, Cost and Consumption, by Facility
The following is a summary of the utility data provided by the City for each facility. The data for electric, natural gas, and fuel oil consumption and cost were provided for CY2017, CY2018, CY2019, and CY2020. The information for CY2020 appears to be incomplete, thus it is excluded from this analysis. A 3-year average baseline of cost and consumption is recommended for these utilities. The data for water consumption was provided for CY2018, CY2019, and CY2020. It is expected that significant changes in building occupancy in CY2020 due to COVID-19 has impacted the water consumption for this period. Therefore, a 2-year average baseline of water consumption is recommended to better capture normal operations. The City does meter the water consumption of their facilities; however, they are not billed for their water consumption. A water rate of $3.07/CCF and sewer rate of $4.96/CCF as
projected for FY21 in the City of Easthampton Water, Sewer and Stormwater Rate Evaluation report were used to quantify the associated water cost and value of water savings if they were billed for their water consumption. For the next iteration of this report a detailed, 3-year utility bill analysis will be performed on all relevant accounts to breakout the various cost components, such as consumption, demand, and fixed costs. The results of this analysis are then used to quantify the projected energy savings that are included in the performance guarantee.

4) Water Department Facilities that include energy intensive processes, such as the Water Department, are very difficult to benchmark given the large variations within the population. Facilities that perform the same process in the same climate can vary significantly in their energy consumption based on their methodology and capacity, thus making traditional benchmarking somewhat unreliable. Honeywell has estimated savings for this facility based on past project experience and findings from the preliminary walkthroughs. Given the high process electrical consumption the electric savings are conservatively estimated at 3%, with fuel savings estimated at 15% and water savings estimated at 5%.
