The Need for Energy Management Effective energy management is an increasingly critical focus area for utilities and energy service providers, as well as end-customers. Energy consumption needs to be minimized without compromising on comfort and other ergonomic considerations such as appropriate humidity, fresh air, carbon dioxide levels, and so on. An efficient energy management system helps optimize energy consumption for heating, ventilation, air conditioning, refrigeration, lighting, fire systems, and security systems, ensuring that energy is used only when needed. An advanced energy management system can ensure monitoring of building conditions, equipment status, utility sub-metering, climatic data, and demand limiting that includes load scheduling and duty cycling. Such a system can also focus on maintenance (remote operation and control of equipment, generation of maintenance schedules, and diagnosis of breakdowns), and record generation (modification or replacement analysis, energy conservation documentation). Planning for Efficient Energy Management Many enterprises are now developing different hardware, software, and analytical solutions for energy management. Effective planning serves as the foundation for this exercise. Planning for a building energy management system starts with the layout of the building. Based upon the floor space area, the cooling or heating capacity needs to be determined; this should be greater than the expected maximum requirement for a given area and set of environmental conditions. This might require installation of multiple chillers with separate piping plans. Another important factor to be considered is that certain chillers might have lower procurement costs but higher operational costs due to lower efficiency. Typically, higher efficiency chillers are associated with a higher procurement cost but a lower operational cost. If the business decides to install higher efficiency chillers, they will need to consider the breakeven tenure involved. For lighting, the aim is to leverage as much natural light as possible. This can be hampered by factors such as reflection glare of neighboring buildings. High floor space can also prevent the utilization of natural light. In such a case, the type of lighting installation becomes important. It is imperative to ensure optimization of procurement cost, energy efficiency (operating cost), and the life of each energy consuming asset. The power factor also plays a key role. It indicates the relationship between real power (power consumed by electrical equipment) and apparent power (power that is drawn by equipment but not completely used, so that it includes wasted energy). If the power factor of an asset is low, it implies a loss of energy. Therefore, energy management also calls for effective planning and monitoring of the power factor. 5
