Daylight guidance systems are linear devices that channel daylight into the core of a building This paper analyses costs and benefits of using the two main classes of daylight guidance to light offices as an alternative to conventional electric lighting The work demonstrates that daylight guidance is generally not economical using conventionally accepted measures of both cost and benefit. It is shown that if intangible benefits associated with the delivery of daylight to offices are included in an analysis a more favourable balance of cost and benefit is obtained The implications of this for practical use of the systems are discussed (C) 2010 Elsevier Ltd All rights reserved

Daylighting in shopping malls: Customer's perception, preference, and satisfaction

M. S. Mayhoub, Emad H. Rabboh

Summary: With the rapid improvement in artificial lighting systems, the challenges for energy-saving daylighting systems will become more difficult in the future. A field survey was conducted to explore the benefits of daylighting from the perspective of customers in shopping malls. The study found that daylighting is more important for improving users' mood than saving energy. Illumination was ranked as the most important element in the shopping malls' internal environment, and the connection to outside views and the presence of sunlight enhanced customers' ability to recognize daylight utilization and increased their satisfaction. Lighting quality, rather than the source of lighting, plays a significant role in enhancing customer satisfaction.

Characteristics of droplets emission immediately around mouth during dental treatments

Chaojie Xing, Zhengtao Ai, Zhiwei Liu, Cheuk Ming Mak, Hai Ming Wong

Summary: This study experimentally investigated the emission characteristics of droplets around the mouth during dental treatments. The results showed that the peak mass fraction of droplets occurs within the size range of 20 μm to 100 μm, and droplets with a diameter less than 200 μm account for over 80% of the mass fraction. The dominant emission direction of droplets is towards the dummy's head and chest, forming an approximately cone shape.

The reliability of models for converting formaldehyde emissions from wood-based materials to different environmental conditions

Tunga Salthammer

Summary: Monitoring the potential formaldehyde emission of wood-based materials through test chamber investigations has significantly contributed to reducing indoor formaldehyde concentrations. However, the different methodologies used in these procedures prevent direct result comparison. Empirical models for converting formaldehyde steady-state concentrations based on temperature, humidity, air change rate, and loading were developed in the 1970s and have been modified to accommodate the development of lower-emitting materials. Formaldehyde emissions from wood-based materials are complex and require nonlinear regression tools for mathematical analysis.

The effect of spectrally and intensity-modified daylighting on urinary melatonin levels in office workers under real-life conditions

Katarina Stebelova, Katarina Kovacova, Zuzana Dzirbikova, Peter Hanuliak, Tomas Bacigal, Peter Hartman, Andrea Vargova, Jozef Hraska

Summary: This study investigated the impact of reduced short-wavelength light on the hormone melatonin metabolite 6-sulfatoxymelatonin (u-sMEL) and examined the association between previous day's light exposure and u-sMEL. It was found that reducing short-wavelength light during the day did not change the concentration of u-sMEL. Personal photopic illuminance was positively correlated with u-sMEL in the reference week. The illuminance had a significant impact on u-sMEL, as shown by the evaluation of the mean of all three urine samples. However, this correlation was not found in the experimental week.
