Building lpd changes sample
Building LPD Changes (sample)

Most whole building values reduced or unchanged

[Addendum “by” - completed]


Space type lpd changes sample
Space Type LPD Changes (sample)

Mixed reduction and increase in LPDs based on technology improvements and model corrections.


Added lpd adjustment
Added LPD Adjustment

Room Cavity Ratio Adjustment for relief in unusual spaces

  • Use only when applying the space by space method

  • Calculate the Room Cavity Ratio (RCR) for the empty room:

    RCR = 2.5 x Room Cavity Height x room perimeter length room area

    (Room Cavity Height = Luminaire mounting height – Workplane)

  • If RCR is greater than the RCR threshold for that space type, a 20% increase is allowed

  • For corridor/transition spaces, this adjustment is allowed when less than 8 feet wide, regardless of the RCR.


Retail display allowance reductions
Retail Display Allowance Reductions

Reduced additional allowance for lighting specifically designed and directed to highlight merchandise

Additional Interior Lighting Power Allowance = 1000 watts

+ (Retail Area 1 × 1.00.6 W/ft2)

+ (Retail Area 2 × 1.70.6 W/ft2)

+ (Retail Area 3 × 2.61.4 W/ft2)

+ (Retail Area 4 × 4.22.5 W/ft2),  

Change based primarily on effective use of CMH technology

  • Additional addenda “ct” and “dd” (in process) modify the area thresholds for top and side daylighting


Lighting control for toplighting

  • Control is required for the general lighting over these areas

  • Control must be multi-level photocontrol

    • At least two output levels at 0% - 35% and 50% - 70%

      OR

  • Lighting required for 24-hour operation

[Addendum “x” to 90.1-2007 – Completed]


Occupancy manual on control requirement
Occupancy Manual-on Control Requirement

Automatic control devices shall not be set to Automatically turn the lighting on.

Advanced control incentives
Advanced Control Incentives

When all mandatory control requirements are met for a space AND advanced controls are installed in that space, THEN additional limited lighting power is allowed:
