Energy efficient lighting design for a food processing industry located at composite climate of India

Lighting is one of the major energy consuming sector in any type of buildings. Lighting design plays a major role in Green Building concepts to provide optimized lighting levels and better energy efficiency. This paper is based on the lighting design of a food processing industry adhering to Food and Drug administration Norms so as to achieve Green Building certification. The study is conducted on a food processing industry located at Hyderabad, India. Green Building lighting design follows standards given by Indian Green Building Council (IGBC), American Society of Heating and Air-Conditioning Engineers (ASHRAE 90.1) and National Building Code (NBC) regulations to obtain credits for Green Building certification. Lighting simulations are done on DIALux software in order to analyse the Light Power Density (LPD) values and compared with the standards. Light Pollution reduction at the exterior environment is also a major concern to provide increased night sky access. This paper also gives an outlook of the light pollution from the IGBC perspectives.

Development of an economical digital control method for a continuously running conveyor belt

The main advantage of conveyor belts that we usually use is that we can avoid material spillage to a considerable extent. This is noticeable when powdered materials like sand, cement, cement concrete, coal, etc. are transferred with their help. Other applications in food processing units, bottling plants, and wood log processing companies also make the study on economization of conveyor belt transfer as an important one. This paper presents a study of the development of an economical digital control method to control the movement and the stop of a continuously running conveyor belt. Different types of conveyor belt systems implemented in the industries are also studied in this paper. Simple electronics devices are used in this study. A control strategy for sensing the arrival of the material conveyed on the conveyor belt is done in the study. This method saves times and energy by avoiding multiple run of the belt with same material. The study presented here is done on a rubber belt.
