In this work the problem of the estimation of achange in the dynamics and time-varyingthermal parameters for a wall from experimentaldata is solved in several ways.
The holistic aim of this study is to make clearthe possibility of passive cooling systems usingnatural cool sources produced by cyclic weatherchanges. Here in this study, we focused on apossible use of rainwater for cooling.
A new innovative design concept for the indoorair conditioning systems is proposed. Thisconcept uses passive control and modularly airdiffusion devices and aims complying with boththernial conifort and energy efficiencyobjectives.

Experimental and numerical study of air temperature distribution of anunderfloor air distribution system | 2008 | English
A numerical model of an underfloor air distribution system was created to aid future research on the system's environmental performance. A validated numerical model can serve to minimize the need for costly experimental setups.
Development of behavioural algorithms for thermal simulation of buildings- evaluating constraints on the operation of windows and fans | 2008 | English
Realistic knowledge of window-opening andfans use behaviour is needed, for the thermalsimulation of naturally ventilated buildings. Ifcontrols such us windows and fans wereefective and easy to use, thermal discomfortcould be largely avoided.
In recent years, the insulation and air-tightnesslevels of newly constructed houses in Japanhave been improved for purpose of energysaving. However, a reduced design of airpermeability (i.e.
The effect of downdraft spoilers is questioned.CFD results are presented for a large atriumequipped with downdraft spoilers ("obstacles")to counteract downdraft from glazed faqades.Simulations are in addition presented for oneandtwo-story test roo
This paper discusses the possibility of asimple solar hot water pre-heating system fordomestic hot water supply. In Japan, the fossilfuel use for hot water supply amounts to about30% of the total in residential buildings.
