Exploring the Impact of Natural Light Exposure on Sleep of Healthy Older Adults: A Field Study

Mariëlle P. J. Aarts, Janny C. Stapel, Toine A. M. C. Schoutens, Joost van Hoof

Research Article Studies among people with dementia demonstrated that the sleep quality and rhythm improves significantly when people are exposed to ambient bright light. Since almost half of the healthy older people also indicate to suffer from chronic sleep disorders, the question arises whether ambient bright light can be beneficial to healthy older people. Particularly the effect on sleep/wake rhythm in relation to the exposure to natural light is the focus. It was hypothesised that the sleep quality would b ...

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 ...

Effect of window glazing on colour quality of transmitted daylight

Rajendra Dangol, Thijs Kruisselbrink, Alexander Rosemann

Research Article In this study, the colour quality of the daylight transmitted through different window glazing types is evaluated. The analysis considered four different types of window glazing: laminated, monolithic, coated and applied film glazing ranging in luminous transmittance from around 0.97 to <1. The spectral transmittance data of different window glazing types are taken from the International Glazing Data Base (IGDB) which is maintained by Lawrence Berkeley National Laboratories (LBNL). The study sho ...

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 ...

Development of Fresnel-based Concentrated Photovoltaic (CPV) System with Uniform Irradiance

Irfan Ullah

Research Article Different designs have been presented to achieve high concentration and uniformity for the concentrated photovoltaic (CPV) system. Most of the designs have issues of low efficiency in terms of irradiance uniformity. To this end, we present a design methodology to increase irradiance uniformity over solar cell. The system consists of an eight-fold Fresnel lens as a primary optical element (POE) and an optical lens, which consists of eight parts, as a secondary optical element (SOE). Sunlight is 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 ...

Maximizing the Performance of Laser Cut Panel by Interaction of Ceiling Geometries and Different Aspect Ratio

Ahmed A. Freewan

Research Article The interaction between different ceiling geometries with laser cut panels (LCPs) is investigated using real experiments and computer simulations to maximize the daylight performance of the LCP. In addition, LCP with different aspect ratios (width to depth ratio) is studied using simulation with clear sky conditions in hot climate region. Two main performance parameters are investigated: illuminance level and distribution uniformity in a large space located in a sub-tropical climate region like ...
