茨城県つくば市の茗溪学園中学校高等学校におけるトイレおよび廊下手洗いの抜本的改修計画である。開校以来30年の部分修繕では限界となり、生徒による「トイレ改善委員会」が既存の問題を明確化した。残存する和便器、手洗い時の衛生確保の不備、荷物置場不足、古びて冷たく暗い個室など、課題は切実で多岐にわたった。

これに対し、非接触センサー式便器とセンサー式石鹸手洗い、暖房便座、視線制御を徹底した入口扉の撤去、入口前の荷物置場、明るく清潔感ある乾式仕上げを共通仕様とし、中高それぞれ4フロア・男女計16箇所を、夏期休暇を利用した2年計画で段階的に改修した。

その結果、学園生活の環境が改善されただけでなく、学園全体の印象も刷新され、在校生・保護者・入学希望の見学者からも高い評価を得た。
※なお、本改修の衛生動線の最適化と設備の非接触化は、後にコロナ禍で大きな効果を発揮した。

This project involved the comprehensive renovation of the toilets and corridor washbasins at Meikei Gakuen Junior and Senior High School in Tsukuba, Ibaraki Prefecture. After 30 years of partial repairs since the school’s opening, a complete overhaul had become necessary. A student-led “Toilet Improvement Committee” identified the existing issues, which included remaining traditional Japanese-style toilets, inadequate hygiene at washbasins, insufficient storage for belongings when moving between classrooms, and cold, worn-out toilet cubicles.

In response, sensor-operated toilets and soap dispensers, heated toilet seats, removal of entrance doors with careful visual privacy planning, installation of storage near entrances, and bright, clean dry-finish surfaces were applied as a common specification. The renovation was carried out in 16 locations?four floors each for junior and senior high, for both boys and girls?over a two-year period using summer vacation for phased work.

As a result, the project not only improved the school’s daily environment but also refreshed the overall impression of the campus, earning high praise from students, parents, and prospective students.
Notably, the sensorized facilities and optimized hygiene flow later proved highly effective during the COVID-19 pandemic.
