Abstract

The Clean and Affordable Energy Act of 2008 established that all private buildings over 50,000 gross square feet within the District of Columbia, including multifamily residences, must annually measure and disclose their energy and water consumption to the District Department of the Environment (DDOE). Benchmarking is defined as tracking a building’s energy and water use and using a standard metric to compare the building’s performance against past performance and to its peers nationwide. These comparisons have been shown to drive energy efficiency upgrades and increase occupancy rates and property values. The District of Columbia has chosen U.S. EPA’s free, industry-standard ENERGY STAR® Portfolio Manager® tool for benchmarking and reporting. DDOE is required to publicly disclose the ENERGY STAR® Benchmarking results for each privately owned building that is subject to the benchmarking law, beginning with the 2nd year of benchmarking data for that building. For more information, see ddoe.dc.gov/energybenchmarking.

Purpose

This data is used by the District, building owners and managers, and by prospective tenants and buyers to evaluate and compare the energy efficiency of large privately owned buildings. [For 2011 File:] 2011 energy benchmarking data is being disclosed for privately owned buildings over 200,000 gross square feet that also reported 2010 data. Water benchmarking was not required for submissions for calendar year 2011.

Attributes

  • DC Real Property ID 
    The Square-Suffix-Lot, Parcel, or Complex (Square-Suffix-Regime) number assigned by the DC Office of Tax and Revenue that uniquely identifies the property. In the disclosure, a “*” after the number indicates a reported ID that DDOE has not matched to a lot recorded by the tax office. The spaces and dashes have no meaning.
  • Address of Record 
    Address as recorded by the DC Office of Tax and Revenue.
  • Owner of Record 
    Owner as recorded by the DC Office of Tax and Revenue.
  • Ward 
    Ward as recorded by the DC Office of Tax and Revenue.
  • Property Name 
    Name of property as reported by owner.
  • Address 1 
    Address as reported by owner.
  • City 
    Washington
  • State 
    DC
  • Postal Code 
    Zip Code as reported by owner.
  • Primary Property Type 
    The Primary Use of the Property, as selected by owner.
  • Year Built 
    The year property was constructed, as reported by owner.
  • Reported Building Gross Floor Area (ft²) 
    The Gross Floor Area as reported by owner. The Gross Floor Area is the total size, as measured between the principal exterior surfaces of the enclosing fixed walls of the building(s). This includes all areas inside the building(s) such as: occupied tenant areas, common areas, meeting areas, break rooms, restrooms, elevator shafts, mechanical equipment areas, and storage rooms.
  • Tax Record Building Gross Floor Area (ft²) 
    The Gross Floor Area as recorded by the DC Office of Tax and Revenue.
  • Site EUI (kBtu/ft²) 
    Site Energy Use Intensity (EUI) is the total Site Energy Use divided by the property square footage. Site Energy is the annual amount of all the energy the property consumes on-site, as reported on the utility bills and converted into a single number.
  • Weather Normalized Source EUI (kBtu/ft²) 
    Weather-Normalized Source Energy Use Intensity (EUI) is the Total Source Energy Use, divided by the property square footage, normalized for weather. Weather-normalization is based on National Oceanic and Atmospheric Administration (NOAA) weather data for the zip code. Source Energy Use is the total amount of raw fuel that is required to operate the property. In addition to what the property consumes on-site, source energy includes losses that take place during generation, transmission, and distribution of the energy, thereby enabling a complete assessment of energy consumption resulting from building operations. For this reason, Source EUI is the best way to quantify the energy performance of commercial buildings.
  • ENERGY STAR Score 
    The 1-100 score calculated by ENERGY STAR® Portfolio Manager® that measures how well the property is performing relative to similar properties, when normalized for climate and operational characteristics. The 1-100 scale is set so that 1 represents the worst performing buildings and 100 represents the best performing buildings. A score of 50 indicates that a building is performing at the national median, taking into account its size, location, and operating parameters. A score of 75 indicates that at a property is performing in the 75th percentile and may be eligible to earn ENERGY STAR® Certification.
  • Total GHG Emissions (MtCO2e)  
    Greenhouse Gas (GHG) Emissions are the carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) gases released into the atmosphere as a result of energy consumption at the property. GHG emissions are expressed in carbon dioxide equivalent (CO2e), a universal unit of measure that combines the quantity and global warming potential of each greenhouse gas. Total Emissions is the sum of Direct Emissions (emissions associated with onsite fuel combustion) and Indirect Emissions (emissions associated with purchases of electricity, district steam, district hot water, or district chilled water. These emissions occur at the utility plant, but they are a result of the property’s energy consumption and therefore contribute to the overall GHG footprint).
  • Electricity Use - Grid Purchase and Onsite (kWh)  
    The total annual electricity consumed by the property, both sourced from the electrical grid and generated from any onsite renewable energy generation systems (if applicable), in kilowatt-hours (kWh).
  • Natural Gas Use (therms)  
    The total annual natural gas consumed by the property, in therms (1 therm equals 100,000 British Thermal Units (BTU)).
  • Water Use (kgal)  
    Total annual water consumption in kilogallons (1,000 gallons).
  • District Steam Use (kBtu 
    Total annual energy consumption from District Steam, in kBTU (1,000 British Thermal Units).
  • Other Fuel Use (kBTU)  
    Total annual energy consumption from other fuels, inclusive of fuel oil no. 1, fuel oil no. 2, fuel oil no. 4, fuel oil no. 5 and no. 6, diesel, kerosene, and propane.
  • X-Coordinate (ESRI)  
    The east-west coordinate from the DC Geographic Information System (DCGIS).
  • Y-Coordinate (ESRI)  
    The north-south coordinate from DCGIS.
  • Metered Areas (Energy)  
    The portions of the building for which energy use was reported, when only partial building data was reported. In 2013, DDOE allowed multifamily building owners to only benchmark using meters they had access to, such as only benchmarking using common areas, or benchmarking using whole-building gas but common area electricity. Building owners were instructed to indicate their metering configuration when submitting partial building data. In cases where a partial metering configuration was reported, DDOE has separated out those buildings onto a separate tab. However, many buildings did not indicate a metering configuration and so some of the multifamily buildings in the main tab might also only reflect partial energy data. All other building types were required to report whole building data.
