Proposal for use of natural energy

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).
