Due Dates


When is the Energy Audit due?

The designated year for filing a report detailing the audit is determined by the last digit of the building’s tax block number; buildings with tax block numbers ending in 3 should file their reports before the end of calendar year 2013. Properties that qualify for Local Law 87 compliance should complete an energy audit no more than 4 years prior to the date of filing an Energy Efficiency Report with the Department of Buildings.

The U.S. Green Building Council advises that an audit be started at least 1 year before it is due. This is because an average building takes between 3 to 4 months to complete a high-quality audit but larger buildings may take 6 to 12 months for the same high-quality audit, due to complexity of energy using systems and sheer size of the lot.

Buildings that need to file their reports by the end of calendar year 2013 should begin their energy audit no later than January of 2013.

When is the Retro-Commissioning due?

After building owners have determined their due date for filing the Energy Efficiency Report (determined by the last digit of the building’s tax block number; e.g. if 3 à file in 2013), Retro-Commissioning on building base systems should be conducted no more than 4 years prior to the filing year.

The U.S. Green Buildings Council recommends that retro-commissioning be started 12-18 months before the report is due. This is because the timeframe for retro-commissioning depends on size and complexity of the building, seasonal considerations, scale of deficiencies and other factors. You need to ensure that your building is compliant with list of 28 measures under Local Law 87 before you submit the energy efficiency report to the Department of Buildings. 

To illustrate, some properties may be operating with only a central heating system requiring retro-commissioning analysis to be conducted during the heating season for data accuracy, which could add 3 to 4 months. Such properties should start the process no later than January of the year that the retro-commissioning is due. 

 

Buildings can determine their compliance year by matching at the last digit of the Building Block & Lot (BBL) number to that of the year. For example, buildings with tax block numbers ending in 3 will have to comply by the end of 2013.
