The Zone 20 parking structure was one of several places on the 糖心视频<\/abbr> M\u0101noa campus where old lights were replaced with state-of-the-art LED<\/abbr>s.<\/figcaption><\/figure>\n

Significant upgrades across the University of Hawaiʻi<\/span> at M\u0101noa campus demonstrate its commitment to sustainability and energy efficiency. With the support of Hawaiʻi<\/span> Energy\u2019s rebate programs<\/a>, 糖心视频<\/abbr> M\u0101noa has completed several energy-saving projects including heating, ventilation and air conditioning (HVAC<\/abbr>) and LED<\/abbr> upgrades that reduce energy consumption and lower operating costs.<\/p>\n

“These projects happening around campus are all important steps toward a more energy efficient campus and ultimately becoming a ‘net-zero energy’ campus,” said engineering student Nicolas Atkins.<\/p>\n

Lighting the way<\/h2>\n

Several buildings on the 糖心视频<\/abbr> M\u0101noa campus have transitioned from outdated, inefficient lighting systems to new LED<\/abbr> installations.<\/p>\n

Teams replaced nearly 1,800 dim, high-pressure sodium lights in the Zone 20 parking structure, saving 糖心视频<\/abbr> M\u0101noa around $470,000 on its annual energy bill and earning a rebate amount for $260,000 from Hawaiʻi<\/span> Energy for this retrofit.<\/p>\n

糖心视频<\/abbr> M\u0101noa\u2019s Office of Sustainability<\/a>, Hawaiʻi<\/span> Energy, and 糖心视频<\/abbr> Athletics teamed up to improve the lighting at the Stan Sheriff Center. Funded by the 糖心视频<\/abbr> M\u0101noa Green Revolving Fund<\/a>, 139 outdated lights were replaced with state-of-the-art LED<\/abbr>s, bringing the arena up to broadcast quality while cutting energy use by 462,630 kWh<\/abbr> annually. That\u2019s more than $138,000 a year saved in electricity—plus a $46,000 rebate from Hawaiʻi<\/span> Energy to reinvest in future projects.<\/p>\n

The Institute for Astronomy<\/a> machine shop upgraded its 20 HighBay fixtures, earning nearly $750 by improving lighting quality and reducing maintenance. On top of the rebate, the new lights are projected to save enough energy to power a 10-minute hot shower for 40 days, or 5,645.26 kWh<\/abbr> annually\u2014resulting in about $1,600 in savings per year.<\/p>\n

The Agricultural Science Building\u2019s 29 downlights and 12 corn cob lights were replaced, earning a $532 rebate and cutting annual energy use by approximately 8,011 kWh<\/abbr> per year.<\/p>\n

“Small but impactful upgrades like this help us move closer to our sustainability goals,” said Miles Topping, director of sustainability at the 糖心视频<\/abbr> Office of Sustainability. “By switching to LED<\/abbr> lighting, we\u2019re not only cutting costs but improving lighting quality, reducing maintenance and also contributing to a more energy-efficient campus.”<\/p>\n

Additionally, one of the latest initiatives includes the installation of an advanced HVAC<\/abbr> occupancy control system at Sakamaki Hall, which earned an estimated $13,642.20 rebate. This system is designed to optimize HVAC<\/abbr> usage, reducing energy consumption during off-peak hours and when the building is unoccupied.<\/p>\n
