Course Description• NY state and thus NY city

have recently adopted new energy codes. This seminar will update the audience on lighting related items for the newly adopted codes. A summary of changes will be provided.

Learning Objectives• Codes in use as of 10/3/2016

• Changes from IECC 2012 to 2015

• Changes from Std. 90.1 2010 to 2013

• NY State amendments to the base codes

• NY City amendments to State items and base codes

Items of Note• Changes in IECC 2015 & Standard 90.1 2013

– Both are “re‐written”

– LPD’s – Whole Building/Building Area and Space by Space

– IECC – Decorative allowance back

– 90.1 – many more spaces require bi‐level lighting

– IECC’s Mandatory Additional Efficiency Package Options• 6 options, pick 1

– 10% under either Building or Space by Space (New Construction only)

– Enhanced Digital Lighting Controls

Items of Note• Power requirements

– 90.1 – NYS Amendment changed voltage drop language (Section 8.4.1) to match National Electric Code language – combined voltage drop of 5%

– 90.1 – 50% Automatic Receptacle control is still there (8.4.2) – AND more spaces!

Items of Note• NYC Amendments

– Historic Buildings – Must be on National or State list. – No change, but a reminder:

• 90.1 – Dwelling Units within commercial buildings STILL have to comply• IECC and 90.1 – incorporated LL48 language on occupancy and vacancy

sensors like before.• Occupancy Sensors OFF within 20 minutes

– OPEN OFFICES now require occupancy sensor control– Reduced LPD for Open and Enclosed office and Retail Sales Area– Alterations

• IECC = 20% threshold [NYC]• Standard 90.1 = 20% threshold [NYC]
