Impact of Furniture Layout on Indoor Daylighting Performance in Existing Residential Buildings in Malaysia

Research Article Currently, home-based computing workspaces have developed substantially all over the world, especially in Malaysia. This growing trend attracts computer workers to run a business from their residential units. Hence, visual comfort needs to be considered in addition to thermal comfort for home workers in their residential working rooms. While such rooms are always occupied with furniture, the layout of the furniture may influence the indoor daylighting distribution. Several various furniture layo ...

Design and optical evaluation of a novel asymmetric lens-walled compound parabolic concentrator (ALCPC) integration with building south wall

Qingdong Xuan, Guiqiang Li, Gang Pei, Yuehong Su, Jie Ji

Research Article Solar concentrating system is an effective way of combing solar energy with the building to satisfy the needs besides of electricity and hot water, also includes building heating, refrigeration, dehumidification, which require higher quality heat source. This paper put forward a novel static incorporated asymmetric lens-walled compound parabolic concentrator (ALCPC), which is composed of the mirror CPC and lens-walled structure, and can make full use of the total internal reflection and specular ...

Solar shading in low energy office buildings - design strategy and user perception

Steinar Grynning, Nicola Lolli, Solvår Wågø, Birgit Risholt

Research Article Moving towards passive house-level envelopes, zero-energy buildings, or zero-emission buildings, where the carbon footprints of the buildings are minimal, the performance of the transparent parts of the envelope is vital for ensuring a low energy demand and a desirable indoor environment. Previous studies explored and confirmed that the energy performance of buildings is highly dependent on the design, functionality, and area of the transparent façades in office buildings. Several factors mus ...

Solar Energy Gain and Space-Heating Energy Supply Analyses for Solid-Wall Dwelling Retrofitted with the Experimentally Achievable U-value of Novel Triple Vacuum Glazing

Saim Memon, Philip C Eames

Research Article A considerable effort is devoted to devising retrofit solutions for reducing space-heating energy in the domestic sector. Existing UK solid-wall dwellings, which have both heritage values and historic fabric, are being improved but yet they tend to have meagre thermal performance, partly, due to the heat-loss through glazings. This paper takes comparative analyses approach to envisage space-heating supply required in order to maintain thermal comfort temperatures and attainable solar energy gain ...

Appraisal of the visual environment in an industrial factory: a case study in subtropical climates

Kieu Pham, Veronica Garcia-Hansen, Gillian Isoardic

Research Article The physiological and psychological benefits of daylighting for office occupants have been well explored. Current research usually focuses on visual comfort in office buildings. However, there is limited knowledge about daylight quality in industrial work environments. In Australia, most industrial buildings are built from standard factory structures that employ daylight from skylights and large door openings, with little consideration to daylighting design strategies and visual comfort. In brig ...

Thermographic Mobile Mapping of Urban Environment for Lighting and Energy Studies

Susana Lagüela López, Javier Cereijo García, Joaquín Martínez Sánchez, David Roca Bernárdez, Henrique Lorenzo Cimadevila

Research Article The generation of 3D models of buildings has been proved as a useful procedure for multiple applications related to energy, from energy rehabilitation management to design of heating systems, analysis of solar contribution to both heating and lighting of buildings. In a greater scale, 3D models of buildings can be used for the evaluation of heat islands, and the global thermal inertia of neighborhoods, which are essential knowledge for urban planning. This paper presents a complete methodology f ...

Daylight utilization with light pipe in farm animal production: a simulation approach

Alejandro Pacheco Diéguez’, Niko Gentile, Hans von Wachenfelt, Marie-Claude Duboisba

Research Article Light pipes, which are complex optical systems, offer a passive way to bring daylight to deep buildings, such as agricultural buildings. However, the lack of reliable performance predictability methods for light pipes represents a major obstacle preventing their widespread use. This paper evaluates a simulation approach for performance prediction and identifies key light pipe design parameters affecting their daylight transmission performance. This study was carried out through continuous monit ...
