Abstract

We present observations from evaluation of internal environmental quality of industrial halls with priority on daylighting in combination with the integral lighting. The physical parameters related to indoor lighting in large industrial halls in winter and summer periods were analyzed using in situ measurements and computational methods. These are part of a comprehensive research on indoor environmental quality of industrial halls with the aims of saving energy and providing a comfortable environment for the workers while improving the productivity. The results showed that the procedures used for evaluation of residential or office buildings may not be used for industrial buildings. We also observed that the criteria of occupants’ comforts for indoor industrial buildings may differ from those of other kinds of buildings. Based on these results, an adequate attention is required for designing the industrial buildings. For this reason, appropriate evaluation methods and criteria should be created. We found the measured values of daylight factor very close to the skylight component of the total illumination. The skylight component was observed on average 30% that of the measured daylight factor values. Although the daylight is not emphasized when designing the industrial buildings and its contribution is small, but it is very important for the workers psychology and physiology. The workers must feel a connection with the exterior environment; otherwise, their productivity decreases.

Summary

Introduction

Global warming and protection of environment are increasing issues in the modern society. These serious concerns make the reduction of carbon emissions urgently necessary [1,2,3,4]. Energy production facilitates (such as, power plants) have major contribution in the problems; decrease of energy consumption, mainly electricity for lighting as well as energy for heating and cooling buildings, have been considered as one of the main targets for solving the environmental problems. The decrease of energy consumption in buildings should not violate the comfort and safety of occupants and interfere with the main functions of the buildings. The occupants must enjoy a safe and comfortable indoor and outdoor environment while energy-saving procedures are implemented.
