OUTLINE OF CASBEE FOR RENOVATION (CASBEE-RN) : CASBEE ; comprehensive assessment system for building environmental efficiency Part 4(Environmental Engineering)

AIJ Journal of Technology and Design (2006)

Masaaki Sato Shuzo Murakami Hiroaki Takai Toshiharu Ikaga Hisashi Hanzawa

We have developed assessment systems for buildings known as CASBEE (Comprehensive Assessment System for Building Environmental Efficiency). CASBEE for new construction and that for existing building were already developed and reported in former reports. We have newly developed the assessment system for renovation. Then we would report the outline of it.

C210 Impacts of fuel cost and carbon tax on capacity design of a microgrid

Doryoku, Enerugi Gijutsu Shinpojiumu koen ronbunshu/Doryoku, enerugi gijutsu no saizensen koen ronbunshu (2009)

Shigeru Bando Eiichi Koda Kenichi SASAJIMA Takashi Yanai Morihiro Kinoshita

We developed the scheme of profitability analysis of a microgrid. The scheme consists of 5 processes. The first process is to calculate the optimal sizing of energy supply system in a microgrid by solving Mixed Integer Non-Linear Programming by using The General Algebraic Modeling System (GAMS). The second one is to determine the distribution of system equipment by taking space in each area into account. The third one is optimal operation planning of energy system by taking thermal transfer among areas into account. The forth one is to design electric equipment. The fifth one is evaluation of pay-back time, reduction rate of primary energy consumption and that of carbon dioxide emission. By using this scheme we also evaluate pay-back time about construction of a microgrid in Tokyo.

Improvement of Surface Quality of Continuously Cast Stainless Steel Slabs

Tetsu-to-Hagane (1984)

Hidemaro Takeuchi Shogo Matsumura Takashi Yanai Yasunobu Ikehara

The effect of continuous casting conditions on surface quality of austenitic stainless steel slabs have been investigated in order to roll slabs without surface conditioning.Development of new continuous casting techniques such as high frequency-short stroke mould oscillation, low viscosity-carbonless mould powder, tundish refractories, one piece immersion nozzle and so on, made it possible to improve slab surface quality and to roll slabs without surface conditioning.

Workers' Behavior and Thermal Sensation in Task-conditioned Office

Shinya Nagareda T. Akimoto Shin‐ichi Tanabe Takashi Yanai Masato Sasaki

SUMMARY Field survey in the M-Office which installed Task/ambient conditioning systems (hereinafter referred to as the “TAC”) was conducted in 2005 and 2006. It was intended to investigate the influence of the worker's behavior and task-conditioning to worker’s comfort sensation. In this survey, immediately thermal environment and worker’s behavior were measured, and questionnaire to occupants who worked as usual were conducted. We found that both activity level of occupant and exposed thermal environment is greatly different one by one. It was suggested that an increase in metabolic rate according to worker’s behavior influence on thermal and comfort sensation certainly. It is necessary to recognize the metabolic rate to estimate the occupant’s declaration in a field survey. In an actual office where occupants stay long terms, the tendency that occupant prefer isothermal airflow was seen. It was thought that adjustment performance with wide amount of task air-conditioning airflow and operationality was desirable to cover occupant’s sense integrally or to connect with occupant’s comfort and satisfaction. Based on the knowledge obtained from this investigation, needs for TAC were discussed.

Outline of the approach to low carbonisation by strengthening CASBEE for new construction (2010 edition)

International Journal of Sustainable Building Technology and Urban Development (2012)

Masaaki Sato Shuzo Murakami Toshiharu Ikaga Takashi Yanai Tatsuya Hayashi

CASBEE (Comprehensive Assessment System for Built Environment Efficiency) is widely used as the assessment system for green buildings in Japan. For the promotion of the low-carbon society, it is necessary to take the lead in introducing the assessment method that induces an approach to the low-carbon society into CASBEE. This paper reports the outline of this approach in the 2010 revised edition of CASBEE-NC (New Construction).
