Happy Valley Elementary

Happy Valley Elementary is located in Santa Cruz, California. Happy Valley was looking for a customized approach to designing a project that utilized their Proposition 39 funding. As a single school district, they have limited resources for project planning and management. Mynt Systems was selected to be their energy planning manager. After a year of planning and revising their plan to meet their needs, we were able to design a plan that included new LED light fixtures and lighting controls in every room and a 12.4 kW ground mounted solar system. New lighting in the classrooms was a priority for the superintendent, both because of the increased light quality for the students and the maintenance savings. The lighting control system now provides dimming capabilities as well as vacancy sensors that ensure lights are not left on when the space is unoccupied. A tankless water heater, programmable thermostats, plug load controls, exterior LED lighting and a high efficiency refrigerator provide additional energy and maintenance savings. The annual carbon emissions reductions are equivalent to the following: 5.6 fewer cars on the roads 63,565 fewer miles driven per car 3,004 gallons of gas consumed 9.6 tons of waste in landfills 28,676 pounds of coal burned

Gilroy Prep, Gilroy CA

Gilroy Prep is a charter school located in Gilroy, CA. The school wanted to utilize their Proposition 39 allocation, but was not happy with the solutions that were being provided by the district's consultant. Their main concern was they wanted an HVAC controls solutions that could be managed remotely so the facilities management could handle both Gilroy Prep and their sister school in Hollister. After completing a facility audit and interviews with the facilities team we decided the Pelican Wireless thermostats and the Lutron Energi TriPak lighting controls systems would be the best value for them. In order to maximize the available rebates Mynt Systems completed all 257 fixtures in the five days the school was closed for spring break. Pelican Wireless thermostats were installed in each classroom and office and five new high efficiency heat pumps replaced end of life equipment. Low-e window film was also applied to the south and west facing windows to reduce heat gain. The project was entirely funded with Proposition 39 funds and utility rebates. Rebates received: $44,693 Annual savings: $13,419

Mountain Elementary School, Soquel CA

Mynt Systems visited Mountain School on Earth Day to help explain all the new upgrades and green technology that were installed.

As part of the Mountain School Proposition 39 funding, new LED lights have been installed throughout the school. The new lights use 66% less energy than the fluorescent fixtures they replaced. Combined with dimming capabilities and vacancy sensors, the LED lighting upgrades will save the school approximately 24,000 kwh annually or $4,500. The expected life of the LEDs is 20 years, which will save the school an additional $750 annually in maintenance costs. LED lights are mercury free, reducing potential hazards for students, teachers and faculty as well as benefiting the environment. Click the link below for a more in depth look.

Case Study Mountain School

Sonic Manufacturing, Fremont CA

Sonic Manufacturing is an 80,000 square foot manufacturing facility in Fremont, CA. The heat produced by the manufacturing equipment and the metal halide lighting in the facility was overwhelming the cooling units. A complete LED lighting retrofit was completed for the manufacturing floor and office areas. Each lighting product was carefully selected to ensure the light quality and level in the manufacturing areas was maintained. Low-e window film was applied to all east and west facing windows to reduce heat gain to further reduce cooling costs. The monthly savings generated from upgrading the lighting and windows was then used to finance the replacement of three of the 30 year old HVAC units that had reached the end of their useful life. 

Annual Electricity Savings: $54,492 Annual Maintenance Savings: $3,676

Equivalent to avoiding the carbon dioxide emissions of:

  • 489,632 Miles/year driven by an average passenger vehicle
  • 23,140 gallons of gasoline consumed
  • 220,887 Pounds of coal burned

Toll House Hotel, Los Gatos CA

Toll House Hotel is the seamless blend of an intimate small-town hotel and the modern character that embodies the Silicon Valley. At the heart of beautiful Los Gatos California, at the base of the serene Santa Cruz Mountains, this charming hotel perfectly captures the ambiance of the historic South Bay town.

Mynt Systems completed a full renovation of their HVAC system, LED lighting retrofit from the stairwell and courtyard lights to the parking garage and even the buildings famous year round perimeter Christmas lights. Solar control window films were implemented and help reduce the heat gain and therefore reduce the energy consumption on the air conditioning. All contributing to an enhanced guest experience.

In addition to the above energy savings this property is expected to save an additional $800 annually in maintenance costs.

These energy saving are equivalent to:

54,023 lbs  of carbon dioxide

5.2 passenger vehicles removed

58,344 mile/year driven by an average person

8.8 tons of waste sent to landfills

2,757 gallons of gasoline consumed

26,321 lbs of coal burned
