Energy efficiency: It's for business, not being cool
February 24, 2015 - Green Buildings
How do we define a good investment? Making the most money within a risk - reward paradigm. There are "safe" investments, which you will not likely lose, but you'll sacrifice interest or yield. And there are riskier investments that could make you more money, but risk losing the investment. Smartly investing money in energy efficiency projects is the best of both worlds. The risk is low. The technologies are known; if implemented correctly, they will work in lowering your energy use. A lower wattage light bulb uses less electricity than a higher one. Period. And if a particular technology fails, the vendor will replace or repair it. And if designed right, provide you with many benefits.
And the cost savings are potentially great. LED lights in many cases produce the same light using less than half the electricity of current conventional lamps. In addition, these new technologies last longer than those replaced, saving the building much in O&M costs and allowing management to reassign workers to other more pressing tasks. Also, there is less risk with fewer trips up the ladder to replace lights. I recently performed an evaluation of a large light replacement project. The client's investment was found to have a rate of return of 14% per year over 7 years. And with no risk (the lights work). What investment on Wall St. results in such a return with no risk? Really! Tell me one. Many other strategies - if planned well for your particular building - will result in similar or better yields and benefits.
Some say: "This is great, but where do I get the upfront capital to buy these new technologies?" Given the high rate of return and low risk, many financial institutions would be happy to lend money at low interest knowing their risk of default is low. Now, several government agencies, such as NYCEEC in NYC and Energize-NY in the rest of the State, have set up low-interest loan programs geared to energy upgrades, designed so that buildings have only positive cash flow in these projects. Money is paid back only when energy cost savings are achieved.
The organization The American Council for an Energy Efficient Economy (www.aceee.org) has compiled many financial studies and case studies on energy efficiency upgrades. See the following graph comparing the risk-reward of a typical energy upgrade with that for other monetary investments.
See how energy efficiency projects - again, if designed and implemented professionally - has a low risk index, yet high annual rate of return.
