Buildings that Teach

10,000

The gallons of rainwater collected annually from roof sheds to storage cisterns in the Omidyar Neighborhood and Kosasa Community.

548,000

The number of square feet of mixed-use space – classrooms, office and back of house – that is equipped with LED bulbs.

2,625,516

The amount of kilowatt hours that the photovoltaic system is designed to produce on campus – metered April 2020 to March 2021.

34

The percentage of energy that is derived from photovoltaic sources on campus.

8

The number of electric vehicle charging stations.

* Kilowatt hours = The amount of energy used to keep 1,000 watts running for an hour. Between April 2020 and March 2021, Punahou recorded almost 5 million kilowatt hours on its HECO meter.

Punahou is a national leader in green educational building design. Case Middle School earned a LEED Gold designation, while the Omidyar K – 1 Neighborhood received LEED Platinum status. The Kosasa Community takes this further by being the first net-zero building for energy consumption on campus.

  • Indoor/Architectural Sustainability Features

    • Touch interactive digital monitors can be used to show video, view websites or as a touch-screen for writing and visual diagrams [1];
    • Digital dashboards provide comparative information about energy and water usage in real time across multiple buildings;
    • Ventilation systems prioritize natural cooling as much as possible, including energy efficient fans and clerestory windows that maximize trade winds [2];
    • Water meter displays in restrooms and refillable water bottle stations quantify the number of plastic water bottles saved;
    • Temperature-sensitive display ports alert students when natural ventilation is preferable to air-conditioning [3];
    • Daylight- and motion-sensor lighting systems automatically adjust brightness for exterior light and shut off when the room is empty to reduce energy consumption [4];
    • Exposed structural elements and cutouts of interior walls and lanai floors make elements like insulation, plumbing and electricity visible and teachable [5].
     
  • Outdoor Sustainability Features

    • Photovoltaic panels support the buildings’ net-zero energy consumption [6];
    • Vegetative “green screens” and light-colored roofs absorb and reflect solar heat and reduce the need to cool buildings [7];
    • A 25,000-square-foot native Hawaiian forest environment with trails and boulders supports an outdoor classroom [8];
    • Numerous plants support Hawaiian Studies curriculum, including kalo, palapalai, pili grass, noni, lonomea, koa, kukui and ‘ulu [8];
    • Backyard garden plots are dedicated to each set of ground-floor classrooms, and a 4,000-square-foot community garden is shared by the entire neighborhood [9];
    • Cisterns located outside of each building capture rainwater for gardening [10];
    • Permeable pavers, a gabion wall and bioswale absorb excess runoff – the bioswale also helps to illustrate the interconnected water systems of an ahupua‘a or watershed [11].
