Houses in Egypt are often designed without taking the climate into account sufficiently. Consequently, new houses often have a poor indoor climate, which affects comfort, health and building efficiency. In hot and arid climates, passive cooling system employs non-mechanical procedures to maintain suitable indoor temperature. Thus, they have been increasing the influence of the traditional cooling concepts but with new technology. Therefore, these conditions encourage such a concept to enhance natural ventilation with evaporative cooling and save energy in the New Assiut city. In the present study, the effect of solar chimney parameters on wind tower parameters was numerically investigated as a second phase of the new integrated model. All the detailed mathematical equations and system description are presented in phase one. A numerical simulation is implemented in Transient systems simulation program-Conjunction of multizone infiltration specialists program softwares. The parametric studies of the integrated system in phase two were studied to achieve high performance with new compact small design especially for the hottest days in the summer season. The temperature and airflow rates are predicted iteratively taking into account the zone pressure and the pressure drop in the evaporative cooler component. The result shows that the system achieves nearly at least close to 80 % acceptable comfort range according to Adaptive Comfort Standard of American Society of Heating, Refrigerating and Air-Conditioning Engineers with optimum ventilation rate 414 m3/h for the hottest day. The findings show that the system achieves high performance in the hottest day with small solar chimney dimension and is easy to integrate in the building envelope than the proposed system before parametric studies in phase one.

Indoor air pollutant by indoor microorganism and house dust has caused asthma, allergy and atopic dermatitis of occupants. In order to make clear indoor air quality and health in houses, eight houses of Miyagi Prefecture in Japan have been investigated. As a result, the amount of floating mold was less than European guideline value. Penicillium spp. and Cladosporium spp. occupy more than 50% amount of total mold. Amount of mite was higher in the houses with dog or carpet than others. The number of particles in the air and amount of house dust on the floor in houses with dog and little child became higher than others. In addition, there was a lot of house dust on the floor in houses with large carpet area.

A simulation model for chemical amplification resists is proposed. This model includes a bulk acid loss reaction and an acid diffusion, as well as a crosslinking reaction. Good agreement with experimental patterns was achieved only when these reactions were calculated self-consistently. The calculation revealed that, for designing chemical amplification resists, one of the key factors is the crosslinking reaction sensitivity to post-exposure bake (PEB) temperature. However, in quarter-micron pattern formation, the acid diffusion was found to significantly affect pattern profile as well as the crosslinking reaction dose.
