Optimization of Daylighting Design Using Self-Shading Mechanism in Tropical School Classrooms with Bilateral Openings

Despite its potential, daylighting strategies in school classrooms in the tropical climate regions is little explored in the literature. The use of two-sided or bilateral daylight opening, as well as the self-shading mechanism using sloped walls, are currently seen as potential strategies to achieve good daylighting in tropical buildings.

A Daylight Assessment on Visual and Nonvisual Effects of Light Shelves: A Human-centered Simulation-based Approach

The contribution of daylight to a comfortable environment for occupants has been the subject of studies for years. Light shelves are known as daylight redirecting systems to enhance indoor daylight conditions. Although several research papers have focused on their daylight performance, there is a lack of studies on the performance of light shelves on circadian rhythm.

Lighting to Enhance Wayfinding for Thai Elderly Adults in Nursing Homes

The main purpose of this study was to explore the effects of lighting and other environmental variables in terms of the colour, signage, and furnishings on the indoor wayfinding of Thai seniors in a nursing home. Three major studies were conducted. The first study aimed at exploring the effects of the lighting parameters in rooms in a nursing home environment, which were the opening type, luminaire type, lamp type, and the type of view-out on the wayfinding performance of Thai elderly people.

No-Greenery Line and Greenery-View Factor, New Architectural Design Tools

The paper proposes a new tool for evaluation of the degree of visual contact with the outdoor greenery, the Greenery-View factor (GV), intended to be easy to grasp and simple to use. It starts with the construction of a No-greenery line (similar to the No-sky line) on the vertical section of the building with the neighbouring greenery included.

Annual Performance Assessment of Complex Fenestration Systems in Sunny Climates Using Advanced Computer Simulations

Complex Fenestration Systems (CFS) are advanced daylighting systems that are placed on the upper part of a window to improve the indoor daylight distribution within rooms. Due to their double function of daylight redirection and solar protection, they are considered as a solution to mitigate the unfavorable effects due to the admission of direct sunlight in buildings located in prevailing sunny climates (risk of glare and overheating).

The Impact of Courtyard and Street Canyon Surroundings on Global Illuminance and Estimated UV Index in the Tropics

Exposing oneself to outdoor daylight in the morning can be healthy and harmful at the same time, due to the risk of ultraviolet exposure. The presence of surrounding buildings in the urban context may also influence the risk. This study aims to identify the impact of courtyard and street canyon surroundings of various size and heights on the peak time and values of global illuminances and ultraviolet index (UVI), for the case of a tropical city.
