The Hot and Cold of It Utility Submetering for Savings

 Utility submetering is the implementation of a system that allows a condominium  association or other multi-tenant property to bill tenants for individual  measured utility usage by making use of individual water, gas, or electricity  meters for their relevant utilities.  

 Submetering provides an opportunity for building owners to shift their rising  electricity costs to tenants who lack ownership or control over thermal  efficiency of the structure, its insulation, windows, and major  energy-consuming appliances.  

 Todd C. Quarterman, president of Rochester, N.Y.-based WaterWatch Corporation,  says that many condominium communities built or converted prior to 1980 use  master meters because they did not submeter the utilities, especially their  water.  

 “In many cases, the HOA is bundling the utility costs into the monthly  association fee so homeowners are not required to conserve their usage,” Quarterman says. “Once utilities are submetered and the homeowner is held accountable for their  usage, they will conserve. With water submetering, total consumption will  decrease around 20 to 25% once submeters are installed.”  

 Since the homeowners represent the community association, energy costs will also  decrease making it a win-win for both the homeowner and the association.  

 What’s Out There

 “One of the challenges in auditing when it comes to some older New England condos  is how to provide utility service with each owner unit, be it electric, gas or  water,” says Charles R. Goodwin, director of pricing strategy and administration with  Northeast Utilities, which provides service in Connecticut, Massachusetts, and  New Hampshire. “In some cases, it’s very difficult to run separate lines in each building.”  

 Northeast Utilities operates New England’s largest utility system serving more than two million electric and natural gas  customers in Connecticut, western Massachusetts and New Hampshire.  

 Many factors go into choosing a submetering system, including size of the  property, construction materials, and topography. There are numerous vendors in  the New England market ready to help slash utility costs.  

 Ron Burke, Certified Energy Manager (CEM), and principal of New England-based  energy and utilities metering company Meter Engineering Co., LLC, began doing  submetering in condos about seven years ago. According to Burke, residential  property owners can lower operating costs and shift the risk of future utility  cost increases using proven wireless submetering and utility allocation  systems.  

 By using the company’s Inovonics Tap Watch submetering systems, a condo will have access to the  latest generation of wireless technology for new or retrofit applications that  integrates with electric, gas and water meters.  

 “Centralized data collection and billing software is scalable for up to 2,000  units and optional heat and cool wireless transmitters integrate directly with  standard HVAC equipment,” Burke says.  

 Thomas K. McHugh, president of Pennsylvania-based Monitor Data Corporation,  explains that his Monitor Data 2000 Energy Cost Allocation system is a digital  electronic temperature measurement and data recording system ideally suited for  gas or oil-fired “shared boiler” heating systems, hot water baseboard, convector and fan coil systems, cast iron  radiators, liquid source heat pumps, and individual hot air or warm air  furnaces.  

 The Monitor Data 2000, currently used in 30,000 condo units each month, utilizes  real-time monitoring and testing features so the company can have true two-way  communication to the heating and cooling system temperature sensor in each  individual unit.  

 “Submetering is really the human side of energy conservation. If people have to  pay for what they use, they will use less,” McHugh says. “There are some very significant savings when submetering comes into play.  Electricity, they will use about 15% less on average; water, close to 30%; and  heat, approximately 20%.”  

 The Good, the Bad, the Submeters

 According to a study done by professional engineer and independent energy  consultant Herbert E. Hirschfeld on condos, 20% to 25% of total usage is  consumed by just 10% of all people. His research has shown that residents will  conserve utilities when they are directly responsible for the cost of the  utilities consumed within their residence.  

 “One of the dominant reasons is to make sure customers get the right form of  signals in using energy and electricity in efficient ways,” Goodwin says. “There may be a single meter and the individual tenants never see the bill, so  they don’t know what the full impact is and they may get lax in efficient use of energy.”  

 Once submeters are installed, however, individual homeowners become more  accountable for their usage only and are quick to fix leaks in faucets, close  windows during heating season and keep their air conditioning shut off when  they are not home.  

 “People are much more conscious of how they use energy, heat or water so the  overall cost will go down by 20% and that’s good for everybody,” Burke says. “Residents will only pay for heating and cooling when they are there, and they  will be much more aware of what they are doing, thereby reducing overall  energy.”  

 It’s been proven that customer behavior is inversely related to the price of a  product and customers do respond better to having a bill in their hand. Plus,  if there’s a dispute over a bill, submetering makes it very easy for someone to see how  they are using their energy or water.  

 “They may not believe they used X-amount but with the software I use, I can do an  audit and show exactly when they had their heating and cooling down to a  hundredth of a second,” Burke says. “It does become a headache for some management companies, though, with people  wanting to know all the time.”  

 Direct metering allows for people to choose where they get their electricity  from, and that is true with a condo association as well, since it allows for  greater negotiating power. “They might decide they can get a better price if they go through a third party,  and that’s a reason for submetering,” McHugh says. “By buying in bulk as a condo association they can negotiate the best possible  price for any given utility and pass those savings along to the condo owners.”  

 Objections for submetering might come from seniors, who routinely keep their  homes warmer because of health reasons, or those who live in a building where a  number of people head off to a second home in the winter.  

 “During months that only a few people are using the utility, they can end up  paying a very large share of it. If you have 100 apartments and only 10 people  are using it regularly, they will pay the entire bill,” Quarterman says. “In a small load like that it can be very inefficient and that could cause  strife.”  

 Plus, heat rises so those living on the ground floor are going to require more  heat and question whether it’s fair that they have to pay more.  

 In Demand

 Wireless metering is in vogue, as it saves money on the cost of infrastructure  and makes it easier to collect the data.  

 “You see it a lot, especially in high-end condos that are already finished off,  because they don’t want you poking holes through walls and everything else,” Burke says.  

 A simple installation for a water submetering system monitored by a wireless  network is $220 per unit. Other energy installations cost roughly in the  $200-$400 price range per individual unit.  

 Energy management services such as master bill validation and processing along  with submetering services offers communities further energy savings.  

 “Clearly there is value of having a green building,” says Ed Davis, manager of Pricing Strategy and Administration with Northeast  Utilities. “Energy efficiency supports green initiatives of an association. Submeters can  also offer a lot of good information within the facility among common use and  individual units.”  

 The U.S. Department of Energy offers access to a wide range of state incentives  that can be applied to utility submetering through their Database of State  Incentives for Renewables and Efficiency (DSIRE) program. Submetering a  property can now also provide credits towards the Water Efficiency and Energy  and Atmosphere categories of LEED certification.  

 Making the Change

 To add submetering to an existing condo is not easy. Since the unit owners are  controlling it, the bylaws are already established, so an amendment to those  bylaws would be needed to allow submetering.  

 “Condos are particularly difficult customers because they do have these bylaws or  rules set up where you need two-thirds of the people to say ‘yes’ to something before it can be amended,” McHugh says. “When we go in to a condo meeting in front of the owners and say that 60% of the  people will benefit from this because they will end up paying less, how do you  get 67% of the people to say, ‘Let’s do it’?”  

 The most difficult obstacle to overcome when selling a submetering system to a  community association is getting everyone to agree.  

 “If you are the homeowner with a family of five, you just might rather keep the  current utility payment allocation method bundled inside the association fee,” Quarterman says. “Once the utility is submetered, your bill is likely to increase, while the  single homeowner’s is likely to decrease.”  

 It’s far easier to get submetering into a new condo development, and most will go  that route.  

 “If you are pitching a developer who is developing a condo or converting over,  you pitch them on the idea that the design mechanical system is less costly,” Burke says. “Use that saleable idea that people buying the units are only paying for energy  they use. They can view that as a sales advantage because that’s an attractive thing to many people.”
