Predictive analytics in facilities management

Abstract

Purpose Advancements in wireless sensor technology and building modelling techniques have enabled facilities managers to understand the environmental performance of the workplace in more depth than ever before. However, it is unclear to what extent this data can be used to predict subjective environmental comfort. This study aims to pilot test a methodological framework for integrating real-time environmental data with subjective ratings of environmental comfort. Design/methodology/approach An open-plan office was fitted with environmental sensors to measure key indoor environmental quality parameters (carbon dioxide, temperature, humidity, illumination and sound pressure level). Additionally, building modelling techniques were used to calculate two spatial metrics (“workspace integration” and workspace density) for each workspace within the study area. In total, 15 employees were repeatedly sampled across an 11-day study period, providing 78 momentary assessments of environmental comfort. Multilevel models were used to explore the extent to which the objective environmental data predicted subjective environmental comfort. Findings Higher carbon dioxide levels were associated with more negative ratings of air quality, higher “workspace integration” was associated with higher levels of distractions, and higher workspace density was associated with lower levels of social interactions. Originality/value To our knowledge, this is the first field study to directly explore the relationship between physical environment data collected using wireless sensors and subjective ratings of environmental comfort. The study provides proof-of-concept for a methodological framework for the integration of building analytics and human analytics.

The Impact of the Aromatization of Production Environment on Workers: A Systematic Literature Review

“…The complexity of the aromatization of such spaces, and its control and management; • Preferential focus of manufacturers on the quality of production, economic results and at the same time; and • Focusing manufacturers on [24,26] the protection of the health and safety of employees, which is also related to air quality, especially clean air, ventilation, and temperature.…”

“…Good air quality can be defined as "air in which there are no contaminants at damaging concentrates as controlled by aware power and with which an impressive predominant part (80% or more) of the people uncovered do not express disappointment" [25]. The issue of the working environment in the interior (air quality indoor), is mainly addressed by the legislation of individual countries, or the legislation of entire regions, e.g., for the member states of the European Union, it is a set of EU directives on safety and health at work [26]. The mentioned legislation addresses not only the physical demands of work but also the conditions of the working environment in the interior, e.g., temperature, air conditioning, ambient humidity, lighting, noise, air quality, and chemical fumes, which are specific and different for each business entity and its operations.…”

“…From the studied published results of research, partial research, or studies that deal with IAQ (Indoor Air Quality), The IEQ (Indoor Environmental Quality) shows that the authors examined this issue through questionnaire surveys among employees working mostly in administrative buildings [28,39] and open space offices [26], in laboratory conditions and call centers [46], or residential buildings with air pollutants such as Radon, volatile organic compounds (VOCs) and carbonyl compounds [50].…”
