One of the most difficult aspects of performing energy analysis on existing building projects is calibrating the simulated results from the energy model to the building's actual energy use. Accurate calibration depends on utility billing data or trended performance data from the Building Energy Management System (BEMS) being properly integrated into the energy model. To the novice, this process can easily double the modeling effort, killing a project’s budget. In the first part of this session, you will learn how to build a simplified energy model in Autodesk® Vasari Beta 1.0 software and calibrate the model to monthly utility data in Autodesk® Green Building Studio® web-based software. The second half of the class will cover how to calibrate the simulated results of the DOE2 energy model to the actual building’s energy performance as captured by a properly configured BEMS system. Both of these strategies will be covered in a case study on the Autodesk headquarters building in San Rafael, CA.
Energy analysts, engineers, commissioning agents, and other professionals who are working on existing building projects
Buildings use over 40% of all energy on the planet. Of existing buildings, 99% are small commercial and residential buildings that use 80% of all energy in buildings. Each building in this group is generally too small to be of interest to the traditional professional who uses Building Information Modeling (BIM) or conducts sophisticated energy analysis. So, how are we going to solve this problem? We mash up the latest in mobile hardware, cloud services, augmented reality, and reality capture technologies to produce a solution that enables anyone who is able to play Angry Birds on an Apple® iPad® to analyze a small building in a fun and accurate way.
New subscription-based features in Autodesk Revit software provide significant enhancements to integrated whole-building energy simulation powered by the Autodesk® Green Building Studio® cloud service. This demonstration will highlight the automatic creation of accurate energy model geometry from detailed Revit software elements, such as walls, floors, roofs, windows, etc. This eliminates the time and effort required to rebuild a separate energy model, leaving more time for design iteration and optimization. This class will also show how other energy analysis data, such as thermal properties of building materials and building/space function, can be defined in Revit for use in the energy simulation and how the Autodesk Green Building Studio cloud service supports a more collaborative energy analysis process between architects and engineers, leading to greater accuracy and better design optimization from the earliest stages in the process. Finally, the extensive validation work conducted on this new feature will also be presented. While knowledge of Revit will be beneficial for attendees, it is not a requirement.
One of the unrealized promises of Building Information Modeling (BIM) has been integrated energy analysis. Autodesk Revit software brings us one step closer to modeling every building, every time. The Autodesk 360 Energy Analysis for Revit service, powered by Autodesk® Green Building Studio® software, is the perfect tool to optimize load and 8760 energy calculations in project workflow. Full energy analysis does not require recreating an architectural model’s project geometry. Your firm can deliver better performing buildings, faster.
The process of building detailed energy models with results that attain the levels of accuracy required by utility incentive and green certification programs is typically tedious and convoluted. In response, Autodesk has implemented new energy analysis features for Autodesk® Revit® MEP 2013 and Autodesk® Green Building Studio® software that alleviate some of the difficult and time-consuming aspects of energy modeling for both existing buildings and new construction projects. Using an energy model created to simulate the energy performance of the Autodesk San Rafael, California, headquarters, this class will walk you through the detailed energy modeling process and show you how to use these new features to save time and increase your productivity.
