Multifamily apartment buildings in California could be much more water efficient, according to a new study that shows retrofits provide substantial savings compared to minor improvements. The research, performed by the building efficiency software provider WegoWise, , shows that while California apartment buildings as a whole only used 6% less water in the first half of 2015 compared to the first half of 2013, facilities that used retrofits cut their water use by 25% over the same period.
While the total savings have yet to satisfy Governor Jerry Brown’s 25% water reduction requirement, the study’s authors are quick to note that their data shows retrofits can help drive efficiency. The most effective strategies are comprehensive fixture overhauls including sinks, showers, and toilets, as well as landscaping upgrades such as drip irrigation replacements. The study used information from over 700 California facilities and also highlights simple improvements that can yield big results, such as a Los Angeles hotel saving 30% on water after a toilet retrofit.
