Special Features

Q-1 Indoor Environment
  • Measures against noise from air outlets, air inlets, machine room, air supply ports, and exhaust ports
  • Sound insulation performance of separation wall: Approx. D-40
  • The heat insulation of the exterior walls is improved by the hollow laying method
  • Individual air conditioning systems are separately operable after hours and on holidays
  • The visual environment is improved during daylight hours because classrooms are placed on the north side
  • A daylight factor of about 2.5% can be expected
  • Brightness sensors are installed for initial illumination correction and lighting control
  • Lighting equipment of about 2G is mainly used to prevent glare
  • The design illumination is set at 750 LX based on desk setting
  • There are few dark areas because general lighting is utilized
  • Interior materials are easy to clean and maintain
  • Air conditioning equipment without a cooling tower
  • Natural ventilation of classrooms
  • The effective opening for natural ventilation is 1/10 or over the habitable room area
  • System capable of introducing the outside air into areas requiring it: Individual total enthalpy heat exchanger
Q-2 Quality of Service
  • A universal design that surpasses the induction standards of the Heart Building Law
  • The brick exterior requires no repairs for at least 30 years
  • The interior materials for the interior finish require no repairs for 11 to 20 years
  • Water-saving appliances, dual water tanks, and rainwater storage tanks have been installed, and rainwater is recycled
  • Story height: 4 m
  • 2900 N/m2 or over
Q-3 Outdoor Environment on Site
  • The layout, shape, and design of the building were carefully planned
  • Air drafts were taken into consideration, many plants and trees were planted within the site, and artificial heat is exhausted from a higher position
LR-1 Energy
  • PAL value: 266.1 MJ/m2
  • 20 MJ/m2 or over
  • ERR is between 10% and 25%
  • Measurable by energy type used
  • Natural ventilation
  • Cooling & heating tube
  • A BEMS was introduced
LR-2 Resources and Materials
  • Water-saving appliances are adopted
  • A rainwater usage rate of over 20% was achieved in the initial year (approx. 33%)
  • Water for miscellaneous use is introduced from public utilities
  • Particle boards, etc. are recycled
  • Floor finishing wax, various sealing materials
  • Structural and finishing materials are easy to identify, and interior materials and equipment are easy to separate if repairs are necessary
  • Halon fire extinguishers are not used
LR-3 Off-site Environment
  • Equipment and appliances emitting low NOx and SOx were adopted
  • Equipment and appliances were installed on the roof or in the surrounding area far from the building
  • Artificial heat exhaust is reduced by considering draft outside the site and making use of natural energy
  • Rainwater outflows are controlled
  • Car and bicycle parking areas are provided

These cases are described based on assessment results obtained using CASBEE.
CASBEE is a method for rating the environmental performance of buildings using Building Environmental Efficiency (BEE) as an indicator, which is based on the results of separate scores obtained for Q-1~Q-3 (Quality) and LR-1~LR-3 (Load Reduction).
