Pools clearly have substantial resource
use and emissions, but results are strongly influenced by climate. Florida, California,
and NewYork for example, all have approximately 0.04 pools per capita (1) (41), but their
water, energy, and greenhouse gas emissions are starkly different. Local
conditions are therefore important when assessing the impact of pools. Areas of
highest water and/or energy consumption (Los Angeles, Phoenix, Tampa) are also
areas of high pool concentration where climate is the common driver behind pool
resource use, demand for pools, and population growth.We only looked at a small
selection of possible mitigation measures but found that savings in these high
impact areas are not hard to come by. At the individual household level, simply
covering the pool during winter or reducing the pumping schedule offer
potential savings comparable to or exceeding that of commonly accepted
household efficiency improvements. At the neighborhood scale, we found that a planning
policy favoring community pools in residential subdivision over backyard pools
can yield substantial reductions in the mean household water and energy use
compared to neighboring subdivisions without community pools equivalent to
upgrading every house in the subdivision to high efficiency clothes washer and
refrigerator, low flow shower heads, and compact fluorescent lights.
