The selected firm will be responsible for, but not limited to, the following tasks: 3.1 Data Collection and Assessment: 3.1.1 Review of existing building plans, equipment specifications, and maintenance records. 3.1.2 On-site inspection and inventory of all HVAC equipment, including chillers, boilers, air handling units, fan coil units, terminal units, controls, and associated piping and ductwork. 3.1.3 Measurement of system performance parameters, such as airflow, temperatures, and pressures, where feasible. 3.1.4 Assessment of the building envelope, insulation, windows, and doors as they relate to thermal performance. 3.1.5 Analysis of historical energy consumption data (utility bills) to establish a baseline. 3.2 Energy Modeling and Analysis: 3.2.1 Create an energy model of the existing building and HVAC systems. 3.2.2 Perform a detailed energy use analysis to identify major energy consumers and areas for potential savings. 3.2.3 Develop a series of upgrade options, ranging from minor improvements to full system replacement. 3.3 Development of Upgrade Scenarios: 3.3.1 For each upgrade scenario, provide a detailed description of the proposed equipment, system configuration, and control strategies. Examples of potential scenarios include: 3.3.1.1 Replacement with high-efficiency like-for-like equipment. 3.3.1.2 Implementation of Variable Refrigerant Flow (VRF) systems. 3.3.1.3 Installation of a new Building Automation System (BAS) or controls upgrade. 3.3.1.4 Integration of renewable energy sources (e.g., solar thermal, groundsource heat pumps). 3.3.1.5 Air-side and water-side economizer analysis. 3.3.1.6 Ductwork and piping modifications. 3.3.2 For each scenario, provide a detailed energy savings estimate, including projected reduction in electricity and natural gas consumption. 3.4 Financial Analysis: 3.4.1 For each upgrade scenario, provide a preliminary cost estimate, including equipment, installation, and engineering fees. 3.4.2 Calculate the simple payback period, Return on Investment (ROI), and Net Present Value (NPV) for each option. 3.4.3 Identify potential utility rebates, grants, or other incentives available for the proposed upgrades. 3.5 Final Report and Presentation: 3.5.1 Submit a comprehensive final report detailing the findings, analyses, and recommendations. The report should include: 3.5.1.1 A summary of the current HVAC system's condition. 3.5.1.2 A detailed description of each upgrade scenario. 3.5.1.3 The energy and cost savings analysis for each option. 3.5.1.4 A prioritized list of recommended upgrades based on efficiency, practicality, and financial return. 3.5.1.5 A conceptual design and schematic drawings for the top recommended option. 3.5.2 Present the final findings and recommendations to the Public Building Commission and Town Council.
