Building automation (BA) and smart homes (SHs) have traditionally not been a unified field but varied by their origins, legal foundations, different applications, goals, national funding programs for basic research. Only within the last years that an international common focus appeared. The following overview gives only introduction into topic of BA also distinction to other areas automation, in which networks level (the sensor actuator level) play important role. Finally, scientific...

With the increasing amount of building renovations in Austria, potential increases for replacing conventional national gas heating systems with heat pumps (HP) and thereby reduce CO2 emissions particularly when combined solar photovoltaics (PV). The Austrian subsidization scheme HP PV are different every state, creating confusion inconstancy adopters. This study provides a parametric techno-economic analysis + to identify critical economic parameters on profitability make policy...

The development of smart sensors, low cost communication, and computation technologies enables continuous monitoring accumulation tremendous amounts data for heat pump systems. But the measurements, especially domestic pump, usually suffer from incompleteness given technical and/or economic barriers, which prevents database measurements being exploited to its full potential. To this end, work proposes a data-driven soft sensor approach compensating multiple missing information. sensors are...

Data acquisition by multidomain data provides means for environment perception usable detecting unusual and possibly dangerous situations. When being automated, this approach can simplify surveillance tasks required in, example, airports or other security sensitive infrastructures. This paper describes a novel architecture networks based on combining multimodal sensor information. Compared to previous methodologies using only video information, the proposed also uses audio thus increasing...

The definition of room functions in Building Information Modeling (BIM) using IfcSpace entities is an important quality requirement that often not fulfilled. This paper presents a three-step method for enriching open BIM representations based on Industry Foundation Classes (IFC) with function information (e.g., kitchen, living room, foyer). In the first step, geometric algorithm detecting and defining injecting them into IFC models presented. After deriving IfcSpaces, calculating graph...

International Energy Agency predicts that the global number of installed heat pumps (HP) will increase from 180 million in 2020 to approximately 600 by 2030, covering 20% buildings heating needs. Electric power consumption is one main key performance indicators for pump systems techno-economic perspective. However a common issue prevalent many existing lack electric measurement. The modern installations might be equipped with measurement sensors but this comes at higher system cost...

Building information modeling (BIM) relies on well-defined requirements to ensure data availability, accurate exchange, and model consistency. The delivery specification (IDS) schema has emerged as a standard for structuring alphanumeric in computer-interpretable manner. However, current practices primarily define these entity-based property lists tabular form, which does not fully exploit the capabilities of IDS. This research aims bridge this gap by developing an extended structure that...

Building Information Modeling (BIM) is a process that collects building data in central model. This can not only be used to plan and construct but design the controls for heating, ventilation air conditioning (HVAC) systems. The relevant information about its systems as base controller design, opening new opportunities like automated testing optimization of control strategies, both energy efficiency user comfort. paper shows how BIM including completeness check resulting set enhancement this...

System complexity has reached a level where it is hard to apply existing information analysis methods automatically derive appropriate decisions.

To achieve energy efficiency in buildings, a lot of raw data is recorded, during the operation buildings. This recorded further used for analysis performance buildings and its different components e.g. Heating, Ventilation Air-Conditioning (HVAC). save time it required to ensure resilience by detecting replacing outliers (i.e. samples that are not plausible) before detailed analysis. paper discusses steps involved obtained from absorption chiller using their On/Off state information. It also...
