simple microgrid systems involving solar panels and batteries. Besides providing emergency
backup power, microgrids offer a sustainable and
lower-cost supplement to externally generated
electricity. Drawing on experiences with this technology in Rwanda, Mazzetti recently designed
energy systems for a facility in Northern California that will be one of that state's first microgridequipped hospitals.
A less obvious but no less important lesson involves the operability of mechanical systems. In
Rwanda, the relative shortage of resources, including highly trained engineers, limits the ability to
maintain complex systems. In North America, that
ability is usually taken for granted, but maybe it
shouldn't be. For example, many LEED-certified
facilities with complex designs operate less efficiently than seemingly inferior, 50-year-old systems because they weren't properly commissioned
and don't operate as designed. Presented with
systems that appear overly complex, engineers
frequently look for workarounds and overrides,
creating a solution that's more workable for them
but less efficient than it should be. For this reason, facility designers and operators should look
beyond energy efficiency alone to seek the most
efficient and operable design. If one system is designed to improve efficiency by 35 percent but also
is much more complex, a more basic system yielding only 25 percent more efficiency could be the
better long-term option.
Perhaps the biggest lesson from Rwanda for
Western healthcare facilities is to simplify designs
whenever possible. Don't reflexively assume that
more complexity is always better. Instead, architects and engineers should focus on what's necessary and appropriate for the context; then they can
apply a combination of mechanical and passive
systems, as the teams did in Rwanda, to create facilities that not only are healthy and safe but costeffective and sustainable.
In some cases, this might require reviewing
codes and standards in North America with an eye
toward energy and resource conservation. As such
efforts take root, planners in this country may increasingly recognize the virtue of solutions born in
Africa from necessity. 
