Abstract
Linking Building Information Modelling and Building Energy Modelling methodologies appear as a tool for the energy performance analysis of a dwelling, being able to build the physical model via Autodesk Revit and simulating the energy modeling with its complement Autodesk Insight. A residential two-story house was evaluated in five different locations within distinct climatic zones to reduce its electricity demand. Experimental Design is used as a methodological tool to define the possible arrangement of results emitted via Autodesk Insight that exhibits the minor electric demand, considering three variables: Lighting efficiency, Plug-Load Efficiency, and HVAC systems. The analysis concluded that while the higher the efficiency of lighting and applications, the lower the electric demand. In addition, the type of climate and thermal characteristics of the materials that conform to the building envelope have significant effects on the energetic performance. The adjustment of different energetic measures and its comparison with other climatic zones enable decision-makers to choose the best combination of variables for developing strategies to lower the electric demand towards energy-efficient buildings.
Highlights
Part of the energy consumption in buildings is a consequence of highly demanding appliances and utilities employed to offer comfort and accomplishing daily tasks
The proposed method starts with a physical model, an energy model based on this physical model, and to conclude an energy simulation, an experimental design had not been applied to analyze the result of the interoperability between Building Information Modelling (BIM) and Building Energy Modelling (BEM) methodologies statistically when studying house facilities
Factors A refers to lighting efficiency; factors B refers to plug load, and factors C refers to the HVAC systems
Summary
Part of the energy consumption in buildings is a consequence of highly demanding appliances and utilities employed to offer comfort and accomplishing daily tasks (heating, cooling, lighting, computer devices, cooking, and others). The BIM-BEM interoperability becomes necessary to incorporate energy performance analysis in the early steps of the building project It permits the calculation of Energy Use Intensity (EUI), allocation of annual energy budgets, predict the year energy consumption, comparing HVAC systems and appliances, utility schedules, and defining energy and comfort standards. It is all for helping in the decision-making process to select competent and sustainable models towards energy-efficient buildings [3,4]. BEM methodology executes the facility’s energy performance through its simulation, using predefined criteria about the building composition and utilization [4] At this level of the analysis, the design tools and the simulation tools appear as two categories of calculation performance. The first one allows the description of the lighting and HVAC (Humidity, Ventilation, and Air Conditioning) system’s size and operation; while the second one presents the dynamic calculations considering the whole year, assessing the indoor quality and comfort, energy demand, and payback periods, saving measures [15]
