Energy Conservation Requirements for Existing Buildings

In December 2009, the New York Council adopted a series of laws aimed at improving the energy efficiency of existing buildings in the city. Each of the four bills refers to another aspect of improving energy efficiency in the city’s buildings as follows: energy conservation standards during the renovation of buildings; annual marking and disclosure of the energy stand; obligatory modernization of the lighting system and sub-meter counters; and mandatory energy audit, retrospection and modernization. The initiatives described here, along with several other related legal acts, are part of the extensive efforts that the city calls “a greener plan for larger buildings”. Some important details of each act are described below.

Council draft 564-A (Local Law 85 of 2009): Requires that renovation of existing buildings meet the minimum standards for energy conservation. The result of this law is essentially the new york city energy conservation code based largely on the New York State Energy Construction Code, but with amendments to the wider use of it for the renovation of existing buildings. Before the introduction of this law, energy conservation standards were only applied to new construction projects and changes in buildings, as a result of which at least 50% of building systems or subsystems were replaced. According to the amended code, the additions, changes, repairs and repairs must correspond to the energy code as if it were a new construction. “Change” generally includes any structure or renovation that requires a permit, and “adding” generally includes any expansion or extension of the conditioned space, floor surface or height of the structure. Here’s what I’ve learned about how to start an engineering consulting firm.

Unaltered parts of the building; some changes that do not increase energy consumption; and projects covering historic and landmark buildings are excluded from one or more aspects of the code. The Act is effective for all projects that submit building approval documents to the Department of Buildings on July 1, 2010. Or later. The basic structure and purpose of the Energy Law Code remains the same, but has been changed and updated twice since the original adoption by Local Law 48 of 2010 and local law 1 of 2011.

Bill Council 476-A (Local Law No. 84 of 2009): Requires building owners to conduct a comparative analysis of energy and water consumption in some municipal and private buildings at least once a year. Requirements for urban buildings include buildings with an area of ​​10,000 square feet or more that are owned by the city or for which the city pays energy bills. Benchmarking is also required for private buildings with an area exceeding 50,000 square feet; many buildings on the same tax batch, totaling more than 100,000 square feet; and many condominium buildings belonging to the same governing board, totaling more than 100,000 square feet. Some public and private properties are exempt from the requirements. Benchmarking was required until May 1, 2010. For urban buildings and May 1, 2011 for private owned buildings.

Owners are required to submit data to the online database tool developed by the US Environmental Protection Agency (EPA), which is used to track and assess energy and water consumption in relation to similar buildings. The Finance Department was obliged to make the result data publicly available by September 1, 2011. For municipal buildings; September 1, 2012 For private non-residential buildings; and September 1, 2013 for private residential buildings. These reports are now available on the program website at the top of this page.

Draft law No. 973-A (Local Law 88 of 2009): Requires building owners to modernize lighting systems in all existing buildings exceeding 50,000 square feet; many buildings on the same tax batch, totaling more than 100,000 square feet; and many condominium buildings belonging to the same governing board, which together exceed 100,000 square feet (called “covered buildings”). All upgrades must be completed by January 1, 2025, in accordance with the lighting standards for new buildings existing at the time of the upgrade. The exemptions for lighting systems are in line with the municipal energy code, existing since July 1, 2010, as well as with those included in some occupational groups classification.
