Taikan Elementary School

Located at the entrance to Taikan Green Tunnel, one of the Eight Scenes of Nanying, Tainan Municipal Taikan Elementary School has been promoting courses on arts and cultures for a long time and known as the “rural Vienna”. Our low-lying school is faced with various problems, including poor permeability and drainage, hardening surface soil, damages caused by termite infestation, and excessively high utility bills. Through the Sustainable Campus Project, we came up with a comprehensive planning and improvement program. The implemented items in 2013 were as follows:

I. Campus Renovation
    1. Permeable pavement: make pavement surface permeable and ensure water storage in underground reservoirs

  Permeable greenway: we demolished impermeable flower beds and built new ones with non-woven fabric, recycled and fragmented pebbles, soil and granular composition. When it rains, surface water trickles down the soil, so the water can be used for planting greenery. When it pours, excess rainwater will be discharged into drainage through permeation tubes.

  Pebbles on top of drains: we calculated the amount of runoff on campus based on its elevation and changed the originally narrow and uncovered drains around the East Building. We widened the drains, adjusted their elevation, and covered them with pebbles in order to ensure unobstructed drainage.

  Seepage trenches with pebble surface: to the west of the East Building, we built two seepage trenches with pebble surface—we used recycled and fragmented cement blocks as the base and laid crushed stones and pebbles on top. By doing so, water can trickle down, and the place won’t be waterlogged after rain.

  Clear clogged drains: to ensure a fully functioning system, we drilled holes in the old ditches and cleared clogged ones to the south of sports fields and the North Building. We also placed pebbles on top of drains and the permeable zones on the sides so that it won’t be waterlogged and muddy after rain.

  2. Energy conservation: design control loops for lighting at different areas.
We changed the switch circuits for interior lighting. There is one switch for each fluorescent lamp for the users to know which lamps they have switched on, and more energy can be saved.

II. Environmental Curriculum
  All construction projects are teaching materials. In line with campus renovation, we designed a series of curriculum in which we used Water Fairy to tell stories about water, pollution, and permeable pavement. We guided students to get used to using energy-saving lights and enabled them to take part in installing turfs and growing plants that attract butterflies. In addition, we integrated curriculum on environmental protection and arts and humanities. We asked students to use recycled natural materials to create installation art and vegetable-and-fruit-shaped ceramic art works, which were used to decorate fences in the “Cape of Good Hope Project.”
