Transcript of New York City: Greener, Greater Buildings Plan
The Greener, Greater Buildings Plan
City Climate Leadership Awards
September 5, 2012
Mayor Bloomberg released PlaNYC in 2007, a comprehensive sustainability plan to create a greener, greater New York City.
The 2011 Update focuses on 10 issues:
Parks and Public Space
Brownfields
Housing and Neighborhoods
Water Supply
Waterways
Energy
Transportation
Air Quality
Climate Change
Solid Waste
The culminating goal is to reduce citywide greenhouse gas (GHG) emissions by 30% below 2005 levels by 2030

75% of citywide emissions come from buildings
85% of existing buildings will
still be here in 2030
New York City has three major energy efficiency policies to reduce GHG emissions from buildings
3017
BROAD: The Greener, Greater Buildings Plan
• Will reduce almost 5% of citywide GHG emissions
• www.nyc.gov/ggbp
NEW: NYC Green Codes Task Force
• 111 proposals to green local codes, with 51 reducing energy use in buildings
• www.nyc.gov/gctf
DEEP: 30x17 and Mayor’s Carbon Challenge
• Accelerated sectors to achieve 30% GHG emissions reduction in 10 years

New York City Energy Code
Benchmarking
Audits and Retro-commissioning
Lighting Upgrades and Sub-metering
The Greener, Greater Buildings Plan addresses the 12,600 properties that make up half of the city’s square footage
Covered buildings account for 2% of NYC’s buildings but 45% of the energy used in buildings
Buildings >50,000 SF
2% of buildings 45% of total energy use

Local Law 85: New York City Energy Conservation Code (NYCECC)
• Closes a loophole in the state code, allowing New York City to accrue the energy benefits of incremental upgrades
• Allows New York City to make incremental, more stringent requirements
Requirements
• All additions, renovations, and repairs must comply with the latest construction requirements
• Went into effect on July 1, 2010
New York City adopted its own energy code
New York City Energy Code
All large properties must benchmark annual energy and water use
Local Law 84: Benchmarking and Disclosure
•All buildings over 50,000 ft2 (4,645 m2) or groups of buildings on a single lot over 100,000 ft2 (9,290 m2)
• Annually submit energy and water consumption using U.S. Environmental Protection Agency’s online tool (Portfolio Manager)
• Public disclosure of public and private buildings’ energy and water data
Updates
•Benchmarking completed for 2011, 2012, and 2013
Benchmarking
Energy audits and retro-comissioning in large buildings to ensure continuous improvements
Local Law 87: Why conduct an audit and perform retro-commissioning?
• To identify cost effective energy efficiency upgrades
• Return systems in an existing building to achieve better performance, energy savings, and quick paybacks
Requirements
• Conduct an energy audit
• Retro-commission according to check-list provided by the City
• Include all “base” building systems: HVAC, electrical and lighting, domestic hot water, building envelope, and conveying systems
• Every 10 years, starting in 2013 on a staggered schedule
Audits and Retro-commissioning
Lighting and sub-metering will address energy use in tenant spaces
Local Law 88: Why upgrade lighting or install sub-meters?
• Lighting accounts for over 22% of energy use in buildings citywide
•Upgrades have proven to pay for themselves within 6-18 months
• Many tenants are unaware of how much energy they consume
Requirements
•Upgrade lighting systems in all space types except residential to meet the requirements of the energy code
• Install sub-meters on all floors over 10,000 ft2 (929 m2) and for all tenants except residential over 10,000 ft2 (929 m2)
• Submit monthly electrical statements to tenants
• To be completed by January 1, 2025
Lighting Upgrades and Sub-metering
Most of the Greener, Greater Buildings Plan is about energy information

Benchmarking
Audits and Retro-commissioning
Lighting Upgrades and Sub-metering
Benchmarking and disclosure provides basic energy information to building owners and the real estate market.
Audits provide detailed energy systems information on potential cost-effective upgrades to buildings owners.
Sub-metering provides energy use information to non-residential tenants.
More than 2 billion square feet of space has undergone energy and water use benchmarking—more than all other US cities combined

Private Properties: • 12,600 properties; 24,000 buildings • 2.6 billion square feet Public Properties: • 2,730 properties • 260 million square feet
61%
New York City compiled detailed analysis of the first year’s benchmarking data in a groundbreaking report
• Released in August 2012, the first report of its kind in the U.S.
• Based on data from the first year of benchmarking year (2010)
• Benchmarking data was merged with City records of building characteristics
• Analysis by New York University, University of Pennsylvania, and the NYC Mayor’s Office
• Available for download at www.nyc.gov/LL84
Characteristics of covered properties vary by sector and building age

Square Footage by Sector, Based on August 1 Submittals
Number of Multifamily and Office Properties by Age
Buildings demonstrate significant variation in energy use
The highest energy users consume 3-5 times more energy than lowest energy users.

Two scenarios for energy and GHG emissions reductions

50th Percentile potential reductions: • 18% energy reduction • 20% GHG reduction
75th percentile potential reductions: • 31% energy reduction • 33% GHG reduction
The multifamily sector makes up the largest proportion of energy use and GHG emissions

Compliance Rates by Sector
Resources are necessary for a high compliance rate and uptake of energy efficiency
• FINANCING: New York City Energy Efficiency Corporation
• Provides $37 million in loan products for energy efficiency retrofits
• www.nyceec.com
• OUTREACH AND EDUCATION: Green Light New York
• Provides trainings for code compliance, benchmarking, auditing, lighting, etc.
• www.greenlightny.org
• LEASE LANGUAGE: Energy Aligned Clause
• Solves the “split incentive” problem for commercial leases
• www.nyc.gov/eac
Reduce citywide carbon emissions
• The laws will cut greenhouse gas emissions by more than 5%
Job creation
• Generate 17,800 skilled, local jobs and help create a knowledge center for energy efficiency
Cost savings
• Reduce annual energy costs by $750 million citywide
