Primary Differences between 2010 and 2013
Addendum BH: LPDs have been adjusted to account for changes to recommended light levels as published in the new, 10th Edition of the IES Lighting Handbook. Some values have gone up while others have gone down. Three new space types have been added in response to user requests: (i) Copy/Print Rooms, (ii) Loading Docks, Interior and (iii) Computer rooms. Also in response to user requests, new space types for facilities used by occupants with visual impairments were added including corridor, dining area, lobby, restroom, chapel and recreation room. In all cases these modified LPDs are restricted to those spaces that are used primarily by the residents.
Addendum CO: The Building Area LPDs were modified to align with the new Space-by-Space LPDs from Addendum BH.
Addendum BY: The specification of when lighting controls are required was moved from the control section to now being part of Table 9.6.1 such that when a designer looks up the appropriate LPD, they can also look up what controls are required for that space type.
Addendum AT: A definition for 'Daylight Area Under Rooftop Monitor' was added
Addendum AY: The nature of of the thresholds for requiring the use of daylight responsive controls was changed from being based on the area of the daylight areas to the combined wattage of the light fixtures within the daylight areas. Daylighting documentation was added to the 'Submittal' section, requiring the identification of all general lighting fixture within daylight areas.
Addendum BV: The area threshold for when skylights are required in certain space types was reduced from 5,000 to 2,500 sq.ft.
Addendum BF: The scope of the automatic control of 125v receptacles was expanded to include more space types and branch circuit feeders installed for modular furniture. Plug in devices were declared as not being allowed to comply with this provision.
Addendum DC: The requirements for control of guestroom lighting was clarified.
Addendum BQ: The addendum added lighting controls to lighting used in refrigerated display cases.
Addendum BD: The required functional testing of lighting controls is now specified in more detail.
Addendum DT: Lighting that is integral to signage and installed in the signage by the sign manufacturer was granted a temporary exception from the exterior lighting control requirements.
Addendum M: 'Loading Dock' was added as a new exterior area type. In the section on additional lighting power when using non-mandatory lighting controls, the amount of watts used to determine the increased allowance was changed from being based on the wattage of the light fixture to that of the lamps.
Addendum N: The efficacy requirement for elevator cab lighting was reworded so as to be clear that it is the composite lighting in the cab that must have an efficacy of at least 35 LPW; not the individual light fixtures.
