Toilets with an uroflowmeter are used in hospital facility. When experimenting on the drainage load before and after the completion, we verified effect of the examination method of the previous report. As a result, if the loop ventilation method of SHASE-S206 was performed, the jurisdiction pressure fluctuation became ±200Pa or less, too. Therefore, the measurement precision was maintained. Moreover, we presume that it can also contribute to lighten the work load of the nurse by the research of usage frequency.

This paper presents effects of housing electricity and heat source equipments. We studied about energy saving effects of 4 equipments, CO 2 Heat Pump water heater (CO2-HP), Micro Gas Engine Co-Generation System (GE-μ CGS), Polymer Electrolyte Fuel Cell Co-Generation System (PEFC-CGS), and Solid Oxide Fuel Cell Co-Generation System (SOFC-CGS). As the result, we have found that energy consumption and CO2 emission reduction rate is the highest in case of SOFC-CGS. Energy consumption is reduced by 17-20% using SOFC-CGS on Electric Power Load Tracking Operation, and 44-47% on Rated Operation. And CO2 emission is reduced by 5-20% on Electric Power Load Tracking Operation and 22-46% on Rated Operation.

This study proposes methods of the multi-split type air-conditioning system model based on refrigerants thermodynamic properties that improve the computational speed reserving accuracy and extrapolability, and reduce physical parameters setting work. The purpose is to improve the quantitative performance assessment of the multi-split type air-conditioning system. The approximation method of refrigerative physical properties value using the neural network improves the computational speed. When the heat load of indoor equipment is input to the multi-split type air-conditioning system model, the amount of consumption energy is the output. It is found the proposed model can calculate approximate outputs in cases of not only JIS but other conditions.

Next generation waterproofing specifications were discussed in the paper. Much amount of greenhouse gas emission and much cost during service life of 100 years were pointed out through the LCCO2 and LCC calculations of waterproofing membranes renovated by the present specifications. For reducing them, two types of specifications for future waterproofing system, such as an envelope type specification of requiring very few times renovation and a built-in type specification of not requiring renovation, were proposed. The calculated results for the proposed specifications by the new concept show much amount of reduction in LCCO2 and LCC.

Right after the Great East Japan Earthquake on March 1 1, 2011, we examined the lighting in Kamaishi City , Iwate Prefecture that facilitates evacuation to higher ground away from a tsunami at night. From the investigation of the escape routes for evacuees in the center of the city and experiments at the entrance of evacuation destinations, it was found that a series of lights placed along the evacuation paths in the direction toward higher ground could guide evacuees effectively to the safe areas. Then, the evacuation performances were investigated in this lighting environment. Based on this research, it was decided that lighting of the evacuation area entrance should be improved preferentially, and lighting of the city streets and intersections should be installed continuously.
