Exterior Lighting Controls. Provide and install motion sensors, photocells and bi-level (step-dim) control in locations per “Appendix A – Lighting Retrofit Schedule”.
Exterior Lighting Controls. Provide and install motion sensors, photocells and bi- level (step-dim) control per Exhibit R. Exclusions: • Assumes standard 120-277V for all fixtures. • Replacement of existing LED fixtures, occupancy or dimming sensors, unless specifically included in Exhibit R. • The scope of work assumes that there are no broken lenses or ceiling tiles. No provisions have been made for replacing any existing lenses or ceiling tiles. • All lenses will be cleaned of dust and other particles, but no staining or deeper soiling will be removed. • Any replacement for any seismic supports for new fixtures. • Repair or replacement of any existing fixtures including tombstones or fixture lens frames. • Any troubleshooting, repair or upgrade to emergency lighting or egress systems unless specified. • Replacement or repair of ceiling tiles, ceiling track system, or other ceiling surfaces expect where damage was directly caused by Contractor. • All existing wiring is assumed to meet local and state building codes, repairing existing wiring including grounding is excluded. • The scope of work assumes proper power is present for all fixtures. No provisions have been made for power upgrades or repairs, simply a one-for-one fixture or lamp/driver replacement. • The scope of work assumes that existing poles are structurally sound, that no internal wiring or fuse issues are present, that any pole arms are in working condition, and that adequate power is provided to all fixtures. No allowances have been made to bring existing poles, pole arms, wiring or fuses to proper working condition. • Hazardous Substances testing or abatement are excluded. The lighting upgrades are not expected to disturb existing ceiling and wall surfaces. • Emergency drivers beyond as identified above. • Any patching or painting. • Any existing or new water leaks for sub-surface or well type fixtures are excluded from the scope of work and are the Owner’s responsibility, including any leaks that may be caused during the retrofit process.
Exterior Lighting Controls. Exterior Lighting Controls are included within specified fixtures in the ECM 2 and ECM 3 scope. The M&V protocol for exterior lighting controls is based on the recommendations of IPMVP Option A. Option A includes engineering calculations with one-time representative measured values, resulting in measured verification of performance. Under this M&V plan; fixture wattages will be determined from one-time spot measurements from ECM 2 and 3. Baseline run hours of the fixtures will be stipulated, but post-retrofit run hours will be verified with short-term logging. There will be no demand savings for interior lighting controls. Energy Savings Calculation Methodology > Savings Algorithm BaselineEnergy = ∑ ∑(kWRe tro × HrsBase × $ buildings fixtures kWh ) PostEnergy = ∑ ∑(kWRe tro × HrsRetro + $ buildings fixtures kWh ) Savings = EnergySavings − Heat + Cool EnergySavings = BaselineEnergy − PostEnergy Where: kWBase = Baseline fixture kW kWRetro = Post-retrofit fixture kW HrsBase = Baseline fixture operating hours HrsRetro = Post-retrofit fixture operating hours $/kW = Unit cost of electric demand, per baseline $/kWh = Unit cost of electric energy, per baseline > Metering Plan Power consumption measurements of the fixtures are covered under ECM 2 and 3. The fixtures Wattage used will be the wattage after lamp/ballast retrofit to avoid double counting. Fixtures run hours after lighting controls installation will be trended with short-term loggers. As part of the monitoring services, Ameresco will perform a yearly site inspection of ECM 2 and 3. The observations during this inspection will be made part of the Annual Reconciliation Report. No long-term monitoring or inspections are included as part of ECM 2 and 3. ECM 6: Retro-Commissioning The M&V protocol for this measure is based on IPMVP Option A. Option A includes engineering calculations of energy consumption of modified systems based on both measurement and stipulation of system input variables. Stipulated input variables are chosen to account and correct for interaction with concurrent implemented measures. Under this measurement plan, Ameresco assumes performance risk for modified system components and their associated sequences of operation. Ameresco will perform equipment measurements and implement energy management system trends to verify that the performance of the installed equipment will operate according to the Schedule R measure descriptions. For water and air temperature related rCx issues, heat tran...
