Replaced / Removed

  • Section 505 IgCC with Section 505 ASHRAE 189.1 (more robust, can’t count

materials multiple times)

  • Chapter 6 (Energy) & 9 (Commissioning) -> see energy code

Green Code Update

slide-17
SLIDE 17

Appendix A

  • Includes Level II Alterations (50,000 sf+)
  • Includes first time fitouts (10,000 sf+)
  • Increasing req’d number of electives by 2
  • Bird-safe building design guidelines
  • Larger green roof coverage
  • Electric vehicle charging stations
  • Deconstruction
  • More electives for energy conservation, green power
  • More electives for LPD reduction and ADR for lighting

Green Code Update

slide-18
SLIDE 18

DC will adopt:

  • ASHRAE 90.1 (2013) merged with Chapter 7 of ASHRAE 189.1 (2014) = energy

code DC will not adopt:

  • IECC 2015

New:

  • Cleaned up, streamlined language
  • More stringent req’ts for additions (>5%), alterations, core & shells

improvements

  • e.g. bldg. insulation must be brought up to code when roof is replaced
  • Measured Performance Pathway (replaces energy cost budget method with

Appendix G)

  • Stretch goals for Net Zero, Passive House, LBC (tie to incentives)

Energy Code Update

slide-19
SLIDE 19
  • More stringent envelope req’ts:
  • c.i., r-values, u-values
  • SHGC
  • Prescriptive path requires permanent

shade devices

  • Continuous Thermal Barrier
  • Best practices dehumidification &

ventilation

Energy Code Update

  • Exceptions for alterations replacement lighting, lighting load 50%
  • Automatic controls parking lighting
  • Prescriptive req’ts occupancy sensors or auto controls
  • Lower LPD cap space-by-space or building area method. ex: office 0.77 W/sf
  • Additional 20% total LPD reduction in lieu of daylight harvesting controls.
  • Daylight zone simplification (15’ from window, 3’ on either side).
  • Specialty/Decorative lighting capped at 5% of overall lighting allowance.
  • Sign lighting requirements

Energy Code Update

slide-22
SLIDE 22
  • Renewables:
  • Renewable energy space & pathways requirement (25% gross roof area).
  • Prescriptive path requires 20% roof area renewables installation (higher req’ts for

core and shell)

  • Alternate Renewables/Equipment Efficiency (higher Energy Star req’ts) 15%
  • Renewables to include biogas

Energy Code Update

slide-23
SLIDE 23
  • All Commissioning is in Energy Code – applies to all projects (IgCC or LEED

pathway)

  • Envelope Cx - new requirement
  • All bldgs. 50,000+ sf
  • 2 pathways:
  • Document peer review and assembly testing OR
  • Whole building air tightness testing
