With the development of urban economy, the number of tall and supertall buildings is increasing. In order to provide better protection of lives and properties in case of fire, provision of residential sprinkler system should be considered as it is not a mandatory requirement for residential premises in many countries.

Purpose / Context - During the process of ventilation, outdoor fine particulate matter enters indoor space through gaps in the external window of building and pollutes the indoor environment. Penetration factor (P), deposition loss rate (k), and air exchange rate (a) are important parameters to evaluate the number of outdoor fine particles infiltrate into indoor...

The purpose of this paper is to study the effect of S.trifasciatavar.laurentii (variegated snake plant) on indoor environment. The results showed experimental room with three pots of S.trifasciatavar.laurentii was 1.6% higher in the room air relative humidity, 0.997℃ lower in temperature, 15.5% lower in PM2.5 concen-tration, 16.4% lower in PM10 concentration than the control room.

Problem: Roofs receive the most intense solar heat load among all building envelope surfaces in Equatorial-region. Solar heat gain through roof contributes to a significant portion of building heat load. In tropics where building cooling is needed all-year-round, passive methods to reduce heat gain through roof could provide significant cooling energy-savings. Approach: Currently, the most...

Purpose / Context - Particulate matter (PM) is one of the main indoor air pollutions, and it can cause a wide range of diseases that lead to a significant reduction of human life. This study aimed at investigating of characteristics of particle concentrations for PM2.5 and size distribution during different activities in residential houses. Methodology...
