Audit of all water using equipment and identification of opportunities for upgrades with water -efficient fixtures. <br />Facility solar feasibility economic analysis. Provide recommendations for implementing solar projects at City <br />facilities. <br />Consultant will perform a comprehensive analysis of the building systems, and make recommendations on all <br />identified ECMs with detailed cost estimates and cost savings. Consultant will perform an SIR analysis in addition to <br />the simple payback method, based on Present value (Pv) of the recommended improvement, and rank all projects <br />based on both simple payback as well as SIR. A life cycle cost (LCC) analysis will also be performed in addition to the <br />payback analysis. <br />Consultant will perform building simulations using an in-house developed spreadsheet method that take into <br />consideration the manufacturer rated efficiency, equipment age, existing maintenance practices, local heating/cooling <br />degree-days and building envelope composition to compute the potential energy savings from the proposed ECMs. <br />The generated savings will be further discounted to account for interactivities among multiple measures and projects' <br />net resulting energy savings by taking into consideration the building orientation, dynamic heat gains and losses, <br />weather, and architectural effects. <br />Consultant will analyze opportunities for energy conservation for each development including, but not limited to: <br />• Envelope upgrade and weather sealing, additional insulation, and minimization of heat loss. <br />• Improvements to the energy performance of windows and doors through storm windows/doors, window shading <br />films, or replacement with high performance alternatives. <br />• Retrofits to old lighting with energy efficient light fixtures and controls. <br />• Upgrades to older appliances with new Energy Star appliances. <br />• Implementation of smart strips to control electronics and entertainment devices. <br />• Upgrades to older HVAC systems with high efficiency units. <br />• Improvements to pipe or duct insulation and leak reduction. <br />• Implementation of programmable or smart thermostats to avoid unnecessary heating. <br />• Identification of water conservation opportunities (low -flow aerators for break rooms and bathroom sinks, and <br />toilets). <br />• Identification of alternate sources of energy (conversion of electric to natural gas based on cost feasibility). <br />• Identification of all potential energy grants and incentives in the form of rebates from local utilities and other <br />Federal and District of Columbia entities for energy upgrades. <br />• Identification of opportunities for distributed generation and cogeneration based on coincidental electrical and <br />thermal loads for each development. <br />• Identification of opportunities for renewable energy systems (solar photovoltaic and solar hot water). <br />Energy Audit Report Deliverables <br />Consultant will provide a separate Energy Audit Report for each building. Each report will include the following: <br />• Table of Contents and Certification <br />• Executive Summary: Summary of findings in tabular format including installed costs, energy cost savings, and <br />payback. The summary will also include potential percentage reduction in both energy consumption and cost <br />compared to building baseline numbers. <br />• Building/Facility Overview and Existing Conditions (for each building): Overview of the facility, HVAC, and lighting <br />systems, and construction Information, maintenance practices, and expected RUL of major equipment (a photo log <br />as an Appendix). <br />• USEPA Energy Star Benchmarking - A Portfolio Manager, which will compare City's utilization per building type <br />with what is industry standard for similar buildings. <br />• Baseline/Historical Energy and Water Use and Cost/Rate Analysis (with monthly degree-days (and hourly, if <br />available)): Analysis of the energy usage of all equipment, and identification of which equipment is using the most <br />energy and what equipment upgrades may be necessary. This will help Consultant generate an End -Use Energy <br />Distribution Chart that identifies energy consumption by each component. The information will further be used to <br />identify which equipment upgrades or replacements may provide a reasonable return on investment to the GPC. <br />The analysis for any upgrades or replacements will include life cycle cost analysis for economic justifications <br />REV: ATTOAGR.2017.010/EMG Corp FCA Page 1s of 22 <br />
