LL43/10 Fuel Conversions from No. 4 and No. 6 Oil to Natural Gas and No. 2 Oil

IGP manages your fuel conversion project from selecting the engineering design firm to construction completion, including all final inspections and approval by the NYC Dept. of Buildings, Con Edison and the NYC Dept. of Environmental Protection (DEP). To control project costs and keep the project on schedule, IGP updates you with regular site visits and written weekly reports so there are no surprises. Problems are dealt with immediately.

IGP assists you with the feasibility and cost/benefit analysis of converting your heating plant from No. 4 or 6 oil to natural gas; or to No. 2 oil; or to dual fuel (natural gas and No. 2 oil) to reduce your carbon footprint. We work closely with Con Edison to access accurate information about the cost, if any, to connect to new gas service.

In 2011, approximately 10,000 boilers in New York City burned grades Number 4 and 6 oil, the dirtiest heating oil types available.  Approximately 5,200 of these buildings burned Number 6 oil. Following a New York State law passed in 2010 that reduces the sulfur content in Number 2 heating oil beginning in July 2012, the City passed Local Law 43/2010 which created a new low sulfur Number 4 heating oil. These laws combined effectively ban the use of No. 6 oil in New York City by July 1, 2015.

Is your building in one of Con Edison’s new 2018 or 2019 Area Growth Plans ? We can help you to convert your building to natural gas by the 2016 heating season, in accordance with Con Edison’s Timeline and Requirements for Participation in the Area Growth Zone. Here are Con Edison’s Oil to Gas Conversion FAQs.

Local Law 88/09 Lighting Upgrades and Sub-metering Tenant Spaces

IGP assists you in the lighting upgrade and sub-metering of your building, if it is greater than 50,000 square feet, to comply  with the Local Law 88/09.

This law requires large non-residential buildings to upgrade lighting to meet current New York City Energy Conservation Code standards by January 1, 2025. Such lighting upgrades include the following elements: lighting controls (interior lighting controls), light reduction controls and automatic lighting shutoff), tandem wiring, exit signs, interior lighting power requirements and exterior lighting.

If master-metered for electricity, these large buildings must install sub-meters for each large non-residential tenant space of 10,000 gross square feet or more on one or more floors let or sublet to the same person, and provide monthly energy statements. If the tenant space is a a floor with multiple tenancies, each tenancy that is 10,000 gross square feet or less shall have:

(i) a separate sub-meter,

(ii) share a sub-meter with other tenant spaces on the floor, or

(iii) share a sub-meter covering the entire floor.

The owner must file both the Lighting Upgrade Report and the Sub-metering Report with the Department of Buildings by January 1, 2025. For more information please see plaNYC Green Buildings & Energy Efficiency: LL88.
