A case study for developing eco-efficient street lighting system in Saudi Arabia

It is now well-known phenomenon that energy efficiency has highest short-term pay out period to decrease overall energy consumption. The replacement of conventional lighting technology with innovative lighting solutions can save up to 40 % of lighting energy. The ecological evaluation of street light provision system in King Abdulaziz University (KAU), Jeddah is carried out using Sustainable Process Index (SPI) methodology. This study is carried out selecting three commonly used street illuminating devices i.e. High Pressure Sodium (HPS) lamps, Compact Fluorescent (CF) lamp and Light Emitting Diode (LED). The results show that energy consumption can be decreased by a factor of 1 to 4 by replacing HPS lamp with high efficiency LED lamp. Similarly, environmental assessment results reveal that ecological footprint as well as carbon footprint caused by lighting service can also be lowered by replacing HPS and CF lamps with LED lamps

Recent developments in advanced process integration: learning the lessons from industrial implementations

Heat Integration (HI) has been developing in mutual cross-fertilisation with the industrial implementations over the last forty years. From the beginning, HI offered some guidance based on thermodynamic principles and their understanding. However, a number of aspects still need deeper consideration and solved problems have to be considered in more complexity to include the real-life issues. This presentation summarises the results of the three efficiently collaborating research groups: Centre for Process Integration and Intensification - CPI2 at University of Pannonia, Hungary, Faculty of Chemistry and Chemical Engineering, University of Maribor, Slovenia and Process Systems Engineering Centre (PROSPECT) at Universiti Teknologi Malaysia. This team exploits the experiences gathered from the industrial projects as well as from the most recent academic research. The aim of this presentation is to provide some tested and proven guidance for future industrial applications as well as a solid support for getting the results with acceptable and realistic payback periods
