In this paper, a novel analytical method was developed based on statistical energy analysis framework to evaluate sound transmission loss through ventilated windows. The proposed method was compared to numerical and analytical models available in the literature. Results showed the success and advantage of the proposed model in predicting the acoustic performance of the ventilated window and the...

Ventilated windows have the potential to contribute both indoor air quality and energy efficiency in cold climates. A typical ventilated window functions as a solar collector under inward flow direction incident radiation. The is modification of multiple pane which drawn from outside heated through conduction, convection, radiation cavity. In this study, detailed parametric analysis was conduct...

Carbon Monoxide (CO) is the most abundant air pollutant gas and accumulates rapidly to dangerous concentrations even in areas that seem to be well ventilated. Carbon monoxide detectors/alarm systems exist but people who are old, hearing impaired, partially sighted or heavy sleepers may not get the warning or find it difficult to wake up and get out in the event of dangerous concentration of CO ...

The facade of the office levels has mechanically ventilated windows. The warm air in the room is extracted above the lighting units, so that the air also takes up their additional heat. Then this air is fed via specially shaped ducts at the level of the topmost transoms into the narrow cavity of the story-height ventilated windows. Here the air is warmed further by taking up heat from radiation...

Several studies have highlighted the significant disparities between the predicted performance of new buildings and their post occupancy measured performance. Occupant window opening behaviour has been shown to have a significant impact on both classroom indoor air quality and building energy use; and is currently poorly represented in building simulation tools. A post occupancy assessment of a...

The mathematic models for thermal, and PV solar power inserted in the ESP-r, which is the integrating building energy and environment simulation tool, were verified with the measured da ta. Using the verified model, the energy performance of an office building, equipped toward the south with conventional absorptive single facade or unventilated double PV facade or outward ventilated double PV f...

The main objectives of this study were to investigate vernacular passive cooling techniques and their potential application for improving indoor thermal comfort of naturally ventilated, modern brick terraced houses in Malaysia. Field measurement was conducted in two traditional timber Malay houses and two traditional masonry Chinese shophouses to examine their indoor thermal environments. The r...
