DC Energy & Green Code Update
Timeline DC Green & Energy Code Updates Feb 2016 Feb 2017 Green/Energy Green/Energy Q? 2018 TAG starts code TAG completes Public updates code updates Comments? Code updates March 2018 2018 / 2019 clear CCCB and Codes Adoption? legal review submitted to EOM
Code Update DC Green & Energy Codes are approved by CCCB: Draft out for Public Comments Q? 2018. • • Adoption in Q? 2018. • Any projects without permit or design contract will be kicked into new codes. DC Green and Energy Code TAG: • HOK, GHT, WDG, Akridge, Paladino, JLL, WRL Design • DCRA, DOEE, AOBA, DC SEU, IMT
Green Code Update Added Preferred parking req’ts for LE/FE, HOV vehicles • • WaterSense pre-rinse spray valves • Condensate drainage recovery (New Construction & Level III Alterations) • Ventilation req’ts for interior fitouts • IAQ testing ACP for low emitting materials (moved from Appendix A) More stringent • Light pollution req’ts for athletic fields and industrial areas • Water efficiency private kitchen faucets, public & remote WCs 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 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 • Increased insulation & higher performing windows • Permanent shading devices Reduced air leakage • • Waste water heat recovery • Recirculating hot water • Very high efficiency equipment • Condensate drainage recovery (when not req’d) Wet hood exhaust scrubber systems • • Views • Pre-occ AQ testing or flush out (in addition to low emitting materials)
Energy Code Update 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 • 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
