Thermal Characterization of Buildings with as-is Thermal-Building Information Modelling

Developing methodologies to accurately characterise the energy conditions of existing building stock is a fundamental aspect consumption reduction strategies. To that end, case study using thermal information modelling method for buildings (as-is T-BIM) reported. This proposed new based on automatic processing 3D clouds interior zones generates semantic proprietary model contains time series surface temperatures assigned its elements. The as-is T-BIM automatically an BEM with gbXML standards simulation. multi-zone building. In addition, temperature data elements permit calculation their transmittances, increasing calibration options obtained model. test TBIM method, compares by methods one standard same results demonstrate differences in geometry, transmittance, and infiltration values, as well insignificant annual air conditioning or comfort parameters tested. seems indicate shorter times greater accuracy
