Data-Driven Modelling of Smart Building Ventilation Subsystem

Building Information Modelling for Smart Built Environments

Building information modelling (BIM) provides architectural 3D visualization and a standardized way to share and exchange building information. Recently, there has been an increasing interest in using BIM, not only for design and construction, but also the post-construction management of the built facility. With the emergence of smart built environment (SBE) technology, which embeds most spaces...

smart co2 detector prototype development to enhance the effi¬ciency of ventilation system in a building

background:: this study developed a smart co 2 detector, which attach to the general ventilation system to reduce the gas level. methods: indoor air quality measurement was performed in five selected rooms between january 2015 to february 2015 using tsi q-trak tm indoor air monitor 7575. the perceived indoor air quality conditions was gathered using questionnaires adopted from the industrial co...

Data-driven Building Metadata Inference

Towards Data-driven Building Retrofit

Due to the relatively low construction rate of new buildings in Europe, the energetic performance of the building stock can mainly be improved by retrofitting existing buildings. Current methods to derive and assess retrofit measures require either on-site inspection by an expert consultant and code based approaches, or numerical simulations using a building energy model that needs to be first ...

Cfd Modelling of Buoyancy-driven Natural Ventilation Opposed by Wind

This paper presents CFD simulations of natural displacement ventilation airflows in which the buoyancy force produced by a heat source is opposed by a wind force. Cases investigated focus on windbuoyancy force relationships for which a two-layer stratification is maintained. CFD predictions of the position of the interface separating the two layers and the change in reduced gravity (temperature...
