Abstract
A shading device is integrated into a building in reducing the indoor solar heat gained. However, the incorporation of a shading device into an opening provides certain effects on indoor natural ventilation. Its performance in enhancing the indoor airflow is still arguable. For this reason, a comprehensive review was executed to identify the effects of a shading device on the natural ventilation of a building. A schematic review process was executed to identify the published articles that were related to the shading devices at the building openings. Subsequently, 25 articles have examined the shading devices at the building openings. The output parameters that were discussed including, the solar heat gained, temperature, energy consumption, daylighting, air quality, airflow, and thermal comfort. The studies agree that the shading device has certain effects on indoor airflow. The effects can be either good or detrimental, depending on the climatic condition, geographical location, building orientation, opening configuration, the shading function, and configuration. It is hoped that this review encourages more investigations of the combined effects of the shading device on solar radiation and natural ventilation. The combined effects are essential in achieving optimum performance of a shading device, which can reduce the solar radiation penetration and enhance the indoor natural ventilation.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
