There is significant evidence to suggest that buildings consume more energy than initially predicted during the design phase of building procurement. With increasing efforts to reduce the energy consumption associated with the operation of buildings, it is vital that these predictions be improved to represent the operation of buildings more realistically. One approach to bridge this gap would be to include energy consumption due to small power equipment in the energy models. Typically ignored, these end-uses usually represent between 13% and 44% of the total electricity consumption in an office building, according to Energy Consumption Guide 19. Currently there is little data available related to the electricity consumption of small power equipment in the context of office buildings. Existing data published in CIBSE Guide F is over a decade old and the use of office equipment and its associated technologies has changed significantly over this period. This lack of up-to-date benchmarks makes it increasingly difficult for designers to include small power consumption accurately within in their energy models. Following a detailed review of existing benchmarks for small power in office buildings, this paper presents a set of monitored data for a range of equipment commonly found in contemporary office buildings. Key metrics include details of power consumption and hours-in-use for both ICT equipment and kitchen appliances. In addition, a comparison of different laptops of varying specifications is provided and their subsequent impact on productivity is also discussed.
