Abstract

Whilst it is generally accepted that improvements in water management are required worldwide, the relatively low apparent financial cost of water is inhibiting the essential changes. Motivating factors are necessary to enable the transformation and whilst standards such as ISO14046 Water Footprint and even ISO50001 Energy Management provide a framework to allow companies fulfil their corporate and social responsibilities, the cost savings associated with the necessary modifications do not alone provide adequate justification. The reason for this is that the true cost or true value of the water being used is not known. The background to the water predicament along with an outline of the water–energy nexus is articulated in this paper. Details of significant, predominantly industrial, water management studies undertaken in different parts of the world are outlined. A common trend is identified, whereby the true cost of the water is rarely determined and hence unappreciated. In order to remedy this situation within industry, a novel framework for establishing the true cost of water by analysing the value added has been developed and its application to a typical manufacturing factory is described in this paper. The framework may also be similarly applied to other water life-cycle stages. The true cost provides a valuable insight into the operation of the facility, a means for internal and external benchmarking and internal cost control, and also the data necessary to financially justify any modifications required. The data may also be used to assist with the calculation of a water footprint or a life-cycle cost. If the proposed methodology is implemented, changes will be possible which will result in water, energy and cost savings along with environmental benefits. Employment of this methodology, involving a Value System (VS) and a simulation model, would facilitate the application of Information and communications technology (ICT) to resource efficiency and thus may be used to assist in confronting necessary sustainability challenges.

Abstract

The contribution of buildings towards total worldwide energy consumption in developed countries is between 20 and 40 %. This is expected to rise by an average rate of 1.5 % per annum over the next 20 years. Heating ventilation and air conditioning (HVAC) and more specifically air handling units (AHUs) energy consumption accounts on average for 40 % of an industrial site’s energy consumption. Building systems rarely perform as well in practice as anticipated during design due to improper equipment selection or installation, lack of commissioning, or improper maintenance to cite but a few reasons. Studies have indicated that 20–30 % energy savings are achievable by recommissioning HVAC systems, and more specifically AHU operations, to rectify faulty operation. Automated Fault Detection and Diagnosis (AFDD) is a process concerned with potentially automating the commissioning process through the detection of faults. This paper seeks to illustrate the effectiveness of a new rule-based expert system developed for AHUs known as “AHU InFO” when compared to the Air Handling Unit Performance Assessment Rules (APAR). AHU InFO has proven to be more effective than APAR in tests against both derived and field test data on a variety of AHU types. In tests against 52 derived faults, AHU InFO identified all 52 issues whereas the APAR identified just ten primarily due to a lack of instrumentation negating the use of many of its constituent rules. In comparisons against field test data, the comparison sought to highlight the developments implemented in AHU InFO with these tests showing that the AHU InFO outperformed APAR in each category tested.

Abstract

The efficiency of energy usage, coupled with the cost and availability of energy, have a substantial impact on the competitiveness and economic viability of manufacturing enterprises. The current uncertainty associated with energy prices has a significant impact on the manufacturing sector as this industry is exposed to the cost of energy at every level of the supply chain. Energy effi ciency varies dramatically between different industries, processes, and even between different facilities manufacturing similar products. In terms of machine tool energy efficiency, the design, age, maintenance strategy, and operating parameters all impact on the ov erall efficiency. Developing a complete understanding of the energy consumed by individual machine components during machining facilitates the optimisation of machine tool design and also NC programs. This paper examines the application of pattern recognition techniques to the area of machine component recognition. Initially, an overview of commonly used pattern recognition systems is outlined before the design and application of a customised solution, applied to a complex manufacturing problem is described. The system design, implementation, and results are discussed before the paper concludes with some of the limitations associated with the implemented methodology.

Abstract

The continuing inflation of energy costs coupled with the imminent implementation of environmental taxes have placed the manufacturing sector under significant pressure to increase energy performance and reduce emissions. Current state of the art research is focused on reducing the energy consumption of machine tools and process chains. In order to quantify the impact of energy efficient machine and facility optimisations it is first necessary to robustly measure, map, and record the energy requirements of manufacturing facilities. Research projects in the area of machine tool energy performance optimisation are extensive; however, the attention given to the accurate and reliable quantification of machine tool and process chain energy requirements is not comprehensibly addressed in the literature. This paper provides an overview of industrial energy measurement technology and describes a methodology facilitating the effective installation of large scale energy metering systems in complex manufacturing facilities; with an Irish based case study. The aim of the project is to illustrate the benefits associated with absolute energy consumption transparency, only achievable through extensive and continuous power metering. The results of the project, as well as some limitations associated with large scale energy monitoring solutions are also discussed.
