Abstract

The responsibilities of the employer/facilities manager in today′s “commercial” world are extensive when considering the wellbeing of staff and the economic working of the office/building. One element of this tangled web is lighting. The recent publication by the Chartered Institute of Building Services Engineers (the professional body), Lighting Guide No. LG7, Office Lighting (1993), is an invaluable compendium in guiding professional “lighters” and the non‐expert in design standards. The guide is particularly useful not only in considering good practice, but also in identifying subjects where the employer is possibly vulnerable with respect to recent EEC legislation and health and safety requirements for satisfactory VDU operations working; and emergency lighting, among others. Examines the contents of LG7, highlighting areas of particular interest and likely concerns to the inquisitive facilities manager.

Abstract

Purpose

The paper aims to describe the positive and negative effects of night lights in historical sites, as well as the most salient challenges faced by the visitors of these sites and determine ways to address them. The study aims to suggest several light-and-shadow approaches and designs to enhance the experience of visiting historical sites.

Design/methodology/approach

This study identifies problems of nightlife in historical sites with an online international questionnaire to determine the preferences and difficulties faced by visitors of historical sites during day and night. After that Egypt was determined as a sample case of a developing country; its archaeological sites need to be improved. The main problems of historical Egyptian sites were investigated and approaches in developing historical sites with interactive lighting design were presented after an online questionnaire to the Egyptian society.

Findings

The paper shows that archaeological sites need some development, especially in their technological and lighting aspects, to overcome visitors’ low night-time interest in archaeological sites. Research has found certain limitations in the effects of constructing artificial illumination. The study provides modern sustainable solution for some light challenges in historical sites with approaches and solutions to solve it.

Research limitations/implications

The results of that research could be applied in developing countries, but with larger specific studies to the historical urban locations according to the politics of the country.

Practical implications

The paper includes sustainable approaches in developing historical sites with technological lighting design required to enhance historical sites at night-time and make visits more interactive and interesting.

Originality/value

This paper presents an identified need of historical sites visitors’ to study applying modern approaches in enhancing urban historical sites.

Application of appropriate shading device strategies in buildings can reduce direct solar heat gain through windows as well as optimize cooling and artificial lighting

Abstract

Purpose

Application of appropriate shading device strategies in buildings can reduce direct solar heat gain through windows as well as optimize cooling and artificial lighting load. This study investigates the impact of common shading devices such as overhangs, fins, horizontal blinds, vertical blinds and drapes on energy consumption of an office building and suggests energy efficient shading device strategies in the contexts of unique Bangladeshi subtropical monsoon climate.

Design/methodology/approach

This research was performed through the energy simulation perspective of a prototype office building using a validated building energy simulation tool eQUEST. Around 100 simulation patterns were created considering various types of shading devices and building orientations. The simulation results were analysed comprehensively to find out energy-efficient shading device strategies.

Findings

Optimum overhang and fin height is equal to half of the window height in the context of the subtropical climate of Bangladesh. South and West are the most vulnerable orientations, and application of shading devices on these two orientations shows the highest reduction of cooling load and the lowest increment of lighting load. An existing building was able to save approximately 7.05% annual energy consumption by applying the shading device strategies that were suggested by this study.

Originality/value

The shading device strategies of this study can be incorporated into the Bangladesh National Building Code (BNBC) as new energy-efficient building design strategies because the BNBC does not have any codes or regulations regarding energy-efficient shading device. It can also be used as energy-efficient shading device strategies to other Southeast Asian countries with similar climatic contexts of Bangladesh.

Abstract

Purpose

The paper aims to establish a virtual lighting maintenance environment (VLME), and to analyze the visibility-related human factors (HFs) during maintenance operations through interactive simulations.

Design/methodology/approach

First, an accurate task lighting modeling method was developed, which includes lighting information modeling and illuminant parameters calibration. Then, the real-time interaction between the task lighting and three-dimensional virtual human was modeled. After that, the attenuation coefficient of visibility was determined. Also, the HFs’ analysis process in VLME was described in detail.

Findings

A case study of power supply module replacement of radar equipment was performed in VLME. The HFs’ analysis demonstrated that the task lighting significantly affects the visibility, which causes indirect impact on posture comfort and operation safety.

Practical implications

Through evaluating maintenance operation processing in lighting environment, engineers can better analyze and validate the maintainability design for complex equipment, and some potential ergonomics and safety issues can be found and dealt earlier.

Originality/value

An VLME was built for interactive “human-in-loop” maintenance operation simulation, which can support HFs’ evaluation in lighting environment accurately and effectively.

Abstract

Purpose

The purpose of this paper is to examine safety lighting at an existing US government facility.

Design/methodology/approach

Field measurements of exterior illumination were conducted at four building sites housing laboratories, offices and a cafeteria at night and the findings were compared to the industry recommendations, the Illuminating Engineering Society of North America (IES) safety lighting recommendations.

Findings

Laboratory, office and cafeteria building exteriors were classified as “high hazard” due to area wildlife, potentially dangerous equipment and chemicals, the threat of intruders, and uneven terrain. Some sites' existing light levels fell far below industry recommendations and others greatly exceeded recommendations. Most of the existing lighting was uneven, unsustainable, rendered colors poorly, produced glare and/or remained energized when no one was present.

Research limitations/implications

This study is limited by the small number of sites and limited geographical area of the sites. Lighting field studies can improve user safety, save energy and reduce facilities' waste.

Practical implications

This study employs a relatively simple approach to examine safety lighting that facility managers could adapt for their own facilities to inform improvements.

Originality/value

The current lack of lighting field studies, safety lighting research and case studies regarding government facilities is addressed by contributions of this research.

Abstract

Purpose

The purpose of this paper is to address a project for lighting an old town in Italy. Its originality lies in the holistic approach that aims to fulfil several objectives. One is to reduce energy consumption by using efficient lamps and advanced control systems; the second one is to make the network viable and useful for many purposes by integrating ICT devices; the third one is to provide a new identity to the older part of the city by using new technologies and design concepts; while the last one is to ensure street and pedestrian safety according to codes and standards.

Design/methodology/approach

The plan of the city of Bagheria and the stock of luminaires of the city are analysed. A multidisciplinary approach has been adopted in order to: analyse the existing lighting infrastructure highlighting critical areas; design a new displacement and select typologies of luminaries able to provide proper light quality and distribution; propose an aesthetic solution and technical design for relevant historical building; and to include in the design process the concept of a new multifunctional pole. Together with an analysis of social benefits, an assessment of economic costs and benefits are discussed.

Findings

The project allows good energy savings, meets the standard requirements and gives a relevant and strategic improvement in social and environmental management of the city.

Originality/value

The work provides an example of integrated design of street lighting infrastructures for urban renovation in old cities in degraded environments.
