Automatically Creating HVAC Control Strategies Based on Building Information Modeling (BIM): Heat Provisioning and Distribution

Abstract

Building Information Modeling (BIM) data are typically exchanged using the Industrial Foundation Classes (IFC) standard. An IFC-based BIM model is a container for data that is created during the design and planning phase and is therefore a rich source of information for the commissioning phase, in which building services are brought to operation. This paper examines the use of BIM data for automated generation of control strategies for energy systems, thus simplifying and accelerating the commissioning phase. We present a methodology to create control strategies of a building heating system with several variations of renewable energy systems and include both heat provisioning and a distribution system. The control goals include favoring the use of non-fossil energy, which is provided by a combination of photovoltaic system (PV), heat pump (HP) and industrial excess-heat source. Thermal energy storages are integrated for load shifting purposes and the control of the heat distribution system is designed towards the requirements of building physics, occupancy and outside climate conditions. A validation of the approach is presented in a combined SIMULINK and TRNSYS simulation environment.

Building Information Modeling (BIM) Capabilities in the Operation and Maintenance Phase of Green Buildings: A Systematic Review

“…), building service systems (heating, ventilation, air conditioning etc. ), and occupants' behavior, BIM can be utilized to simulate the energy demand of a green building [78,136,137]. Besides that, with the integration of BIM and building management system (BMS), BIM can count and analyze the energy utilization preference of different occupants and the energy consumption of green buildings in various periods and seasons [138].…”

“…Besides that, with the integration of BIM and building management system (BMS), BIM can count and analyze the energy utilization preference of different occupants and the energy consumption of green buildings in various periods and seasons [138]. Based on these, the energy utilization and consumption situations of green buildings can be simulated through BIM [78,136,139,140].…”

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

“…Second, we created a map of the moderately used keywords, presented in Figure 4; to produce this map, we restricted the number of keyword occurrences to the range from 20 to 50. The ten most relevant keywords (RQ-2) were the following: emission (87), BIM tool (48), database (47), comfort (46), gap (45), knowledge (45), adoption (44), building model (44), engineer (44) and green building (43). As can be seen in Figure 4, the APY varied in the interval 2015-2019.…”

“…Table 5 presents the activities of the building's life cycle. As can be seen in this table, the most frequently occurring activities (RQ-4) were the following: information modeling (202), development (177), engineering (56), improvement (56) and control (43). The newest keywords (RQ-8) were the following: questionnaire (APY 2019), control (APY 2018), renovation/refurbishment (APY 2018), classification (APY 2018) and validation (APY 2018).…”

“…The BIM platform can be exploited to ensure the more sustainable design of buildings through the integration of technologies that use renewable energy sources, e.g., facilitating the design of complex PV layouts on facades [5]. Using IFC-based BIM data for the automated generation of control strategies when building energy systems increases the overall quality of the building operation and reduces operational costs [43].…”
