Specifications include, but are not limited to: Specifically, the awarded respondent will evaluate and propose applicable energy conservation measures (ECMs), on a District site-by-site basis, including but not limited to: (a) Heating Ventilation & Air Conditioning (HVAC) system optimization, retrofits, upgrades or replacements. Retrofits shall have comparable air flow and cooling capacities. Identify any defects or deficiencies in the existing HVAC systems and recommended remediation. Calculate annual energy savings based on school site Bell Schedules and Calendars, and climate data for previous 12-months. Indicate any assumptions made in performing energy savings calculations. Indicate what utility bill reductions result from reduced usage, reduced demand, and energy tariff changes. Energy savings and utility bill reduction calculations shall be embodied in Excel spreadsheets that are clearly organized, retain all equations, variables, data and data references and are unlocked for District “what if” evaluations. Energy savings and utility bill savings shall be calculated over the expected/warranted life of each HVAC system type. Proposers shall identify any defects or deficiencies in HVAC systems, and shall specify appropriate remediation measures. (b) Interior and exterior lighting retrofits or replacements. All proposed lighting retrofits shall have comparable luminous intensity and viewing angle. For each lighting fixture type specify (i) quantity, (ii) original lamp type, original wattage, (ii) retrofit lamp type, retrofit wattage. Indicate if new fixtures or ballasts are included. Indicate whether retrofit lighting incorporates lighting detection or motion detectors. Calculate annual energy savings based on school site Bell Schedules and Calendars. Indicate any assumptions made in performing energy savings calculations. Indicate what utility bill reductions result from reduced usage, reduced demand, and energy tariff changes. Energy savings and utility bill reduction calculations shall be embodied in Excel spreadsheets that are clearly organized, retain all equations, variables and data references, and are unlocked for District “what if” evaluations. Energy savings and utility bill savings shall be calculated over the expected/warranted life of each lighting type. (c) Building Automation System (BAS) installation, upgrade or expansion leveraging existing technology. Calculate annual energy savings based on school site Bell Schedules and Calendars. Indicate any assumptions made in performing energy savings calculations. Indicate what utility bill reductions result from reduced usage, reduced demand, and energy tariff changes. Energy savings and utility bill savings shall be calculated over the expected/warranted life of the BAS system proposed. (d) Building envelope upgrades (e) Other infrastructure improvements
