An Integrated Energy Simulation Model for Buildings

“…EnergyPlus is the simulation engine software used to conduct an integrated simulation of the building, system, and plant whereby supply and demand are matched based on successive iteration substitution following Gauss-Seidel updating [20]. Open Studio is used as the API software for developing and parameterizing the model following the principles outlined by Brackney et al [21]. Ambient temperature, relative humidity, solar radiation, and wind speed data for 2017 and 2018 was obtained from local meteorological equipment and converted to two yearly weather files.…”

Retrofit interventions in non-conditioned rooms: calibration of an assessment method on a farm winery

“…Instead, the paradigm involves a 'seed', which is the baseline model around which the analysis is built, and a chain of scripts, which are run by the Workflow Gem and are used to programmatically implement changes to the baseline model. The scripts, called Measures (Roth, Goldwasser, and Parker 2016;Brackney et al 2018;Roth et al 2018), can be generic and reusable across different models and analyses. The chain of scripts and their arguments, as well as the definition of the variables, is described in the 'workflow' section of the OSA.…”

Geometric Accuracy of BIM-BEM Transformation Workflows: Bridging the State-of-the-Art and Practice

“…US Department of Energy's EnergyPlus [148] is chosen as the simulation engine for the case study. EnergyPlus is a mainstream simulation engine implemented in over a dozen third-party applications including Revit Systems Analysis, Design-Builder, Sefaira, Trace 3D, Honeybee, etc., and is extensively verified by academic efforts [78].…”

“…Typically, 'centreline' building geometry definition is adopted, in which walls, floor slabs, ceiling slabs, roof slabs, windows and doors are represented by flat surfaces parallel to the sides and placed in the centre of each particular object [63,34,76]. It is hinted that, in combination with the 'centreline' modelling approach, a predominant way to achieve a BEM geometry is by vertically extruding 2D plans, so as to achieve a geometry referred to as 2.5D [77,78,79,23,72].…”

“…gbXML can be relatively easily integrated to another modelling environment thanks to its domain-specific, simple data structure, and is already well integrated with OpenStudio [78], whose API makes the platform easily accessible to other tools. Therefore many activities focused on further opportunities, discussion of export and interpretation issues, or verification of software implementation across energy modelling tools.…”
