Looking beyond lower energy costs


Beyond the immediately apparent benefits of energy savings and cost reductions, highly efficient buildings can infer a range of additional benefits. Health and productivity benefits in particular can often account for significant savings that are even greater than the entire energy budget. Measurements show that in efficient buildings—labor productivity typically rises by about 6–16%. Since office workers in industrialized countries cost approximately 100 times more than office energy, a 1% increase in labor productivity has the same bottom-line effect as eliminating the energy bill—and the actual gain in labor productivity is ~6–16 times larger than that.
