Say you are a landlord or manager of several or many buildings and electricity is not sub-metered (is your responsibility, not your tenants). The recent huge rise in electricity costs is really hurting you, given that most of your tenants are in long-term leases with low annual rent increases and that you probably have not upgraded your buildings to be more energy efficient. How can you save electricity costs under these circumstances?
- Lighting. There is no longer any doubt. Light emitting diodes (LEDs) produce the same amount or more light but use less than half of the electricity of fluorescent or incandescent bulbs. Years ago, there were some question about their viability. But all concerns have been addressed. Clearly, cutting your lighting electric usage by more than half will save you money and not impact operations. Go for it! If that were not enough, LEDs last longer than fluorescents or incandescents (LEDs do not “burn” anything), and thus, stopping work to replace a non-functioning LED is rare, freeing up your Maintenance staff to do other things tenants may be demanding. While LED prices are higher than fluorescents, the difference is narrowing and electric cost savings more than make up for it. LED upgrades commonly have a simple payback of under 1 year. Since LED lights often last 7, 10, or more years before needing replacement, that’s a lot of savings in your budget (“gravy”) after Year 1. LEDs for common areas and cost sharing with tenants who pay their own electric will benefit you.
Bonus tip: Most utilities and states offer incentives for switching to LEDs. Take advantage of these. However, LEDs is such a good buy, that many utilities are beginning to reduce or even end financial incentives for LEDs. So don’t wait; upgrade to LEDs now – this year – before incentives disappear.
- Appliances. Given their frequent use, appliances in buildings can be significant contributors to energy usage. Refrigerators are the biggest ones. While a user may open and close a refrigerator only a few times a day (for meals), we forget that it is on using electricity to cool or freeze food 24/7, even when away on vacation. It is a big electricity user. Other common devices can be “electricity” or “gas” guzzlers, too (clothes washers and dryers, computer equipment, even coffee makers and microwaves). Many manufactures make lines of appliances that have built in features to minimize the amount of electricity or natural gas needed (for example, the “sleep” mode of a laptop). At a minimum, you should procure appliances with the ENERGY STAR label, as they have been shown to reduce energy usage by 20% or more compared to average models due to their built in features. You don’t have to do anything. Just buy and operate them. Or you can go further and research specific models that will do the job you want and use minimum amounts of energy; manufacturers of such equipment highlight them on their websites. While energy-saving equipment may be more expensive upfront compared to average brands, the energy cost savings will make up the difference in a short time, usually under 2 years. If the typical refrigerator, etc. operates 15-20 years, that is also a lot of “gravy” for you.
Bonus tip: Work with your Procurement Department on this. Guide them to research and find the most energy efficient models of necessary equipment. And let them work their magic to find bargains or buy efficient equipment in bulk so that the energy saving equipment may cost the same as “average” models.
- Heat Pumps. What are these? These are devices that move heat from one place to another. In the winter, it takes heat from the outside and moves it into a room (yes, there is heat outdoors, even on a freezing day!). In the summer, it takes heat from a room and moves it outside. This takes electricity to achieve, but heat pumps use less energy than, say, a boiler combusting natural gas. It is easier to move heat than to produce it! Heat pumps have now been perfected to work effectively even in cold climates. Heat pumps can help a building become all electric, which is cheaper, better for the local air, and needs less maintenance than combusting a fuel. Manufacturers are developing low-cost, easy-to-install heat pumps for easy, reliable building retrofits within a standard window frame. For a large, multifamily building, installing many such units will save significant energy and O&M costs of a boiler.
Bonus tip: Look up and contact your local utility or state or county energy agency. They are aware of heat pumps and likely have programs to answer your questions and provide financial incentives for installing heat pumps. They also may have a list of experienced, vetted vendors. Look through their information as you are doing your homework.
According to the DOE, buildings account for nearly 40% of the nation’s energy usage and that 75% of the 130 million buildings in the US will still be standing in 2050. Thus, upgrading existing buildings to be more energy efficient will be necessary to keep up with and manage rising energy costs. Start with these options to get off to a good start and save energy costs at the same time.
