AGENDA

PlaNYC 2030

• New York City’s long-term plan for the year 2030

• Anticipates 1 million more residents from 2005 to 2030

• GOAL: Reduce CO2 emissions 30% by 2030

• “Will you still love New York in 2030?”

PlaNYC 2030

• Land – 10-minute walk from a park

• Water – swimmable • Transportation – public • Energy – existing

buildings• Air – quality • Climate Change –

building resilience

PlaNYC 2030

Five Boroughs

578 miles of coastline

305 sq mi of land area– 54% is built area– 41% are roads, open space, and

water ways– 5% available for development

Buildings account for 75-80% of NYC’s carbon emissions

85% of building stock anticipated in 2030 existed in 2005 – focus on existing buildings

Greener, Greater Buildings Plan

6-Point Plan

#1 - New York City Energy Conservation Code

• 3 laws affecting buildings > 50,000 GSF#2 - Benchmarking

#3 - Audits and Retrocommissioning

#4 - Lighting Upgrades / Sub-Metering

#5 - Financing assistance

#6 - Green workforce development

3 LAWS: BUILDINGS > 50K GSF

Green Codes Task Force

Mayoral Task Force develop 111 “greening” measures for Construction Codes, Zoning Resolution and other regulations:

To date these have resulted in 16 laws and regulations, with anticipated completion by close of 2013

Overview

• A national energy code• American Recovery and Reinvestment Act• 2009 International Energy Conservation Code• ASHRAE 90.1/2007• 2010 Energy Conservation Construction Code of New York

State• 2011 New York City Energy Conservation Code

• Target for national compliance: For ARRA funding, States must:• Adopt the 2009 IECC for residential and ASHRAE 90.1/2007 for

commercial, or equal, and• Achieve compliance in 90% of new & renovated space by 2017• USDoE provides monitoring guidance for States to measure

compliance, and New York State is developing its program accordingly

NYC Energy Conservation Code


Local Law 85/2009 was effective July 1, 2010; but

Updated bill, Local Law 4/2011, was effective December 28, 2010


• By State law, must be more stringent than State Energy Code

• Only administrative portions affected – technical chapters unchanged from State Energy Code by LL4/11• Exception: LL48/2010

• Lays the groundwork for additional modifications to reduce energy use



• Will be published as a NYC Construction Code later this year

• LL4/11 – NYC Amendments to 2010 ECCCNYS• 1 Administration• 2 Definitions• 3 Climate• 4 Residential• 5 Commercial• 6 Referenced Standards



• ASHRAE 90.1/2007 acceptable to use instead of Chapter 5 for commercial buildings

• 1 RCNY §5000-01, “Energy Code Compliance Rule,” is being amended and will be available for public comment in February

• §ECC 101.4.3 – Alterations • All alterations (A1, A2, A3 applications) must indicate compliance on PW1 form, and

address exemptions and exceptions in energy analysis• Note conditions under which an alteration project may not need to comply – to be

addressed on energy analysis• Exceptions: There are now 8 exceptions – to be addressed on energy analysis



• Chapter 1: Administration• Demonstration of compliance -- §101.5.3

• PW1, Section 10: Professional Statement • All NB, A1, A2 and A3 applications must check compliance, except as specifically

listed under exemptions• Exemption may ONLY be checked if the entire application is exempt
