Things2People Interaction toward Energy Savings in Shared Spaces Using BIM

Abstract

People in shared building space have an important role in energy consumption because they can turn on/off equipment and heat/cooling systems. This behaviour can be influenced by giving then locally tailored context information (energy consumption, temperature, luminosity) and information about the cost of their actions. This paper presents an approach to create personalized local energy consumption predictions in a building using past sensor data, correlated with external conditions to create local context predictions. This prediction is sent in real-time to people’s mobile devices in order to influence their behaviour when increasing or decreasing temperature using heating or cooling systems. This information is essential for sustainability actions in shared spaces, where this information can have an important role. Also, the data (temperature) representation in the building information model (BIM) module can help the user understand environment conditions and, together with the user sharing their thermal feelings, can be used to change behaviour. This approach using BIM’s representation models allows Things2People interaction to improve energy savings in these shared spaces.

Building Information Modelling and Internet of Things Integration for Facility Management—Literature Review and Future Needs

“…Furthermore, the ICT application in several processes (e.g., BIM) and scenarios have been investigated. In most cases [52,103,104,[106][107][108][110][111][112][113][114][115][116][117]119] BIM is used to process or display buildings' geometric data, FM data and energy data collected through sensors. Among these articles, References [104,111,113,[115][116][117]119] focus on users' behaviours.…”

Among these articles, References [104,111,113,[115][116][117]119] focus on users' behaviours. These researches aim to raise users' awareness of energy efficiency and consider building users as a primary factor to improve energy efficiency and IEQ.…”

3D IoT System for Environmental and Energy Consumption Monitoring System

“…To make buildings more efficient and sustainable, common approaches focus on optimization of building control systems using automation rules and dashboard visualization as B. Mataloto et al [6] did with an Building Management System, or other IoT systems focused on energy management such as in [7,8]. User interaction with monitoring systems can have a significant impact not only in energy savings, but also modeling people's behavior [9] and creating sustainable users communities [10].…”

“…This tool was tested in 12 different homes where participants started to discover specific appliance consumption, and how much energy a determined activity could spend such as using the microwave or air conditioning system. In [9] and [47], authors used a user-centric approach with IoT and BIM models, similar to our work, to interact with users, promoting behavioral changes and people engagement. Another concept work in energy management and savings was developed in [48] as a smart university platform that was able to aggregate the sensor data, environmental data, and data center efficiency, displaying the information on a web service.…”

How BIM Contributes to a Building’s Energy Efficiency throughout Its Whole Life Cycle: Systematic Mapping

“…Such integration offers the opportunity to increase the efficient use of energy resources in buildings, improve employee productivity and create better working conditions for tenants [16,[18][19][20]. IoT real-time sensing data (energy, air temperature, relative humidity and CO 2 concentration) represented in a BIM-based building management system help the user to identify the indoor climate, determine the level of thermal comfort and indoor air quality and even change occupancy behavior [21]. The application of BIM technologies involves not only the planning, design, construction and monitoring of new buildings to increase their energy efficiency, as open BIM technologies can efficiently integrate energy conservation measure data into BEP simulation models during the refurbishment of buildings [10].…”
