4  Current version - October 4, 2012  Distributed on October 9 th  Non-substantive changes  Editorial  Clarification  Substantive changes  Provisional data collection Section – hours of operation Section controls Protocol Revisions

5 Provisional Data Collection Lighting system hours of operation The RTF is interested in validating the lighting operating hours for the following building occupancy types and their associated space use types:  Assembly  Education, university, and college  Industrial/manufacturing  Warehousing  Exterior area lighting with dimming or photocell control To validate the simplest reliable method for estimating lighting hours of operation described in Section 6.4, measured data are collected for the above occupancy types from a sample of program projects. For each project in the sample, the annual hours of operation are estimated for each space use type and control type (collectively referred to as usage group) listed in project’s savings calculator. To estimate operating hours, a representative sample of fixtures is metered and trend data are collected. The data are collected for the efficient lighting system after it has been installed and commissioned. The data is collected for a minimum of fourteen day periods including two weekends during operating schedules that represent typical space use for the year. Where lighting operating schedules and hours of operation for typical workdays vary due to significant seasonal or other schedule variations, the data are collected for fourteen days during each time period representative of each schedule variation. A variation is considered significant if it is likely to account, in the judgment of the practitioner, for at least a 25% variation in the projected daily or weekly operating hours for the season. For example, If a university or assembly facility has four distinct seasons or semester occupancy schedules and hours of lighting system operation that vary by more than 25% from one another, four metering periods of fourteen days each would be required to collect best practice data under this provisional protocol.

6 Provisional Data Collection Lighting system hours of operation- continued Metered data from the targeted occupancies will be compared to the savings control fractions in the calculator and on-site interviews regarding hours of operation and designed control schedules to determine the simplest reliable method. For the target occupancies, additional data are to be collected through interviews with on-site facility operators, in addition to the baseline data in 6.1 through 6.7 of this section. That data includes: Data Collection For Warehouse Occupancy Sensor Applications  Warehouse area occupied hours (number of shifts - duration)  Number of isles to be controlled  Power by isle or by switched area circuit(s)  Power of switched load (or percent of full power when dimmed)  Estimated frequency of isle or switched circuit area access over occupied hours (number and duration of incursions) Data Collection For Parking Structures or Lots for Switching or Dimming Controls  Number of floors and power per floor, or lot area  Baseline hours of operation and baseline control method(s)  Hours of parking allowance  Parking structure daily occupancy rate (week day, weekend, holiday, evenings)  Perimeter lighting power and circuits eligible for switching  Interior bi-level power levels and control schedules  Basis for estimation of interior occupancy switching hours by floor Stairwells for Bi-level Switching Using Occupancy Controls  Number of Floors  Power by floor landing and stair flight per floor

7 Controls The RTF is interested in validating the controls savings factors for the following control and space use types:  Lighting occupancy sensor control for warehouse aisle lighting  Day lighting control for open office space lighting  Lighting control for school classrooms and gymnasiums  Bi-level control for stairwell lighting  Occupancy sensors for warehouse applications  Occupancy sensors for parking lots and parking garages Provisional Data Collection

8  Other protocol revisions  (review October 4, 2012 version of protocol) Protocols

9  RTF meeting presentation  Seek approval of provisional nonresidential lighting protocols Next Steps
