Energy Performance Evaluation of Mission Critical Facilities: A Case Study of Communications Buildings in the Oil & Gas Industry
Mission critical facilities, such as communication buildings, support critical operations, namely telephone, radio and IT network equipment that serve vital communication functions in the oil and gas industries. These buildings have unique environmental and operation requirements that necessitate cooling systems that match those requirements. To eliminate or reduce any chance of costly business interruptions, communication building systems must run 24/7 with code-specified redundancy in energy-intensive power, cooling and air moving systems. Putting these special requirements together, communication buildings energy use intensities (EUI) have been, and will continue to be, of great concern when compared with those of office buildings. One of the main contributors to this high EUI is the nature of the required cooling. While building comfort cooling systems are appropriate for “human occupancy”, they are not well suited to precise regulation of temperature, humidity, air quality and 24/7 availability. This paper evaluates the energy performance of unmanned communication buildings located in one of the major oil & gas companies. Using ASHRAE level II energy audit, the individual building loads, e.g., lighting, cooling, air distribution, water heating, battery and IT equipment, have been calculated, along with building EUI baseline. Through a recommended bundle of no-cost and economically feasible low-cost energy conservation measures, building EUI reduction target has been set, which achieves nearly 25% energy savings without negative impact on reliability. The information provided in this paper is indispensable to those who are concerned with the topics of energy efficiency of mission critical facilities.
