Submetering Natural Gas


Submetering natural gas is the process of measuring and recording the use of natural gas for multiple units within a building. This can be useful for a variety of purposes, such as allocating the cost of natural gas usage among different residents, monitoring the energy efficiency of a particular system, or identifying and fixing gas leaks.
Submetering natural gas involves installing gas meters for each unit. These meters are often smaller than the main meter that measures the total gas usage of a building. These meters are ideally placed on the incoming gas line for a unit or, in less ideal situations, on individual appliances, heating systems, or water heaters to track their specific natural gas consumption. The data from these meters can then be used to calculate the cost of natural gas usage for a specific resident and then NES can bill them accordingly.

What is Submetering?

Gas Submetering involves the installation of equipment to measure and bill each unit’s gas use. Submetering has been used since it was invented in the early 1920s.

What are the benefits?

If you are trying to recover operating expenses for your apartment complex, Submetering is the answer.
When a property installs gas submeters, residents work harder to conserve gas, dramatically reducing overall consumption. Residents are also responsible for their own usage, which almost eliminates the gas expenses for the landlord.
Submetering can also increase the value of your apartment complex or mobile home park.
Bottom line: The return on the investment is usually seen within 12 months because the residents pay for the gas they use.

What is RUBS and how can it help real estate that can’t be metered?

RUBS, or Ratio Utility Billing System, is a method of allocating natural gas costs among residents in a multi-unit property. It is typically used in properties where it is not feasible or cost-effective to install individual meters for each unit, such as older buildings or properties with shared plumbing systems.
Under a RUBS system, NES calculates the natural gas usage for each unit based on the total natural gas usage for the property. This is based on factors such as the number of occupants, the number and type of appliances, and the property’s square footage. The total cost is then divided among the individual units according to a predetermined ratio.
RUBS can help real estate that can’t be submetered by providing a fair and equitable way to allocate natural gas expenses among residents. It can also help reduce natural gas waste and improve the property’s overall energy management.

Does Submetering have regulations?

Yes, submetering is regulated by various state and local laws. These regulations typically govern issues such as the installation and maintenance of submeters, the accuracy of the meters, and the billing of residents for their natural gas usage. The regulations governing submetering can vary depending on the location and type of property, so it is important for property owners or managers to familiarize themselves with the relevant laws in their area if they choose to submeter without NES.
