The Sacred Heart Academy Library is part of the Sacred Heart School's Lower and Middle School campus. The library is intended as an educational demonstration of the school's goal "to teach students to be stewards of the earth's resources." The library has achieved zero energy while meeting a very modest construction budget - in fact, all Zero Energy features, including photovoltaic panels, were included within the already established budget.

In 2014, NorthBay VacaValley Hospital became one of the first U.S. health care facilities to install an energy-efficient, ultra-smart outdoor LED lighting system. The award-winning project was so successful that the NorthBay Healthcare group is now considering expanding the VacaValley system and retrofitting the outdoor lighting at other sites.
UC Davis established the Smart Lighting Initiative (SLI), an effort to reduce campus-wide lighting electricity consumption at least 60% below 2007 levels. The first phase of this program included a large-scale deployment of over 1,500 network-controlled LED streetlights, area lights, post-tops, and wall packs. The “ultra-smart” lighting installation has reduced annual energy use by an estimated 1,231,758 kWh, saving $120,909 annually in energy and maintenance costs.
In 2012, University of California Davis upgraded its exterior lighting as part of the university’s Smart Lighting Initiative. Wall packs on campus, like other exterior lighting fixtures, were retrofitted with dimmable LED sources, motion sensors, and wireless controls. This allowed the units to be incorporated into an adaptive campus-wide lighting control system. The system offers an intelligent, networked approach to lighting and energy management with improved lighting quality and optimal energy efficiency.
In the summer of 2010 the California Lighting Technology Center (CLTC) and Philips Hadco produced a bi-level solution that combined a dimmable LED source and a mounting collar equipped with occupancy sensors. The collar provides 360-degree occupancy sensor coverage. This demonstration involved whole-head replacement of the existing luminaires, but results could also be achieved with a retrofit kit. The new luminaires feature good color quality, improved efficiency and a longer lifespan. Adaptive controls enable the bi-level luminaires to reduce power to 50% during vacant periods and increase to 100% light output when occupants approach. Switching between the two light levels maintains adequate light for security and wayfinding while maximizing energy savings.
Sinisa Novakovic, owner of Mishka’s café in downtown Davis, had two goals for the recent lighting upgrade in his café: create a cozy, inviting atmosphere for customers and save energy. In the main seating area alone he was able to cut his lighting energy use 85% by upgrading to LED lighting. Throughout the rest of the café, energy consumption for lighting has been cut in half, reducing Mishka’s annual energy use by over 10,000 kWh and saving Novakovic nearly $2,000 every year in energy costs. The lighting upgrade will have paid for itself after just eight months.
