Upcoming OpenStudio Trainings
July – August 2016
Date and Times:
- July 28,29 and August 1,2,3 2016 (1-5pm EST)
- July 27 – Optional SketchUp Training for an additional $150 (1-3pm EST)
This 5-day online training course will teach students how to leverage the free NREL OpenStudio modeling ecosystem to quickly and efficiently generate flexible models for energy analysis. Students will learn effective modeling workflows for using the OpenStudio Sketchup Plugin to construct building form and fabric and assigning space attributes. HVAC and service hot water systems will be configured using the OpenStudio Application. The OpenStudio Application integrates with NREL’s Building Component Library (BCL), providing libraries of pre-defined configurable energy conservation measures for easily modifying energy models. PAT (Parametric Analysis Tool) will be used to demonstrate how model variants can be configured to run in cloud computing environments (Amazon EC2). Students will also be exposed to OpenStudio’s capabilities for extension through Ruby Scripting, both for creating custom energy conservation measures and for generating useful summary and detailed output.
- Learn to use the OpenStudio modeling ecosystem to effectively model the energy and lighting performance and consumption for new and existing buildings.
- Learn how careful OS model configurations can allow for rapid alterations and manipulations.
- Learn how to use the power of OpenStudio “measures” to easily evaluate changes to your building model.
- Learn how to configure the Parametric Analysis Tool (PAT) for conducting modeling studies
- Learn how to effectively extract and interpret results from PAT modeling studies
Date and Times:
- Preconference session Monday August 8 from 1 to 5pm
As interest in performance verification and model validation continues to grow, Energy Modelers should consider familiarizing themselves with new IMPVP Option D approaches. IPMVP represents a set of internationally accepted protocols for quantifying project related savings, including the Option D approach. Calibrated energy models form the foundation of all IPMVP Option D savings estimations. Option D activities involve generating a calibrated ‘as operating’ model, and the subsequent replacement of components of the calibrated model to estimate project savings. In addition, Option D is the only IPMVP option which can be accomplished post facto. This powerful attribute allows IPMVP adherent savings to be determined for nearly ANY energy efficiency project. Until recently, cost-effective methods for quantifying the accuracy of model calibration efforts have been difficult for practitioners to develop and/or execute, preventing Option D from being applied to projects in any scalable manner. However, recent advances in the OpenStudio suite of tools provide new ways for users to interact with a calibration framework that can be used for either new construction or retrofit projects – including incorporating uncertainty analysis. Course attendees will be exposed to this framework, allowing them to explore the uncertainty of input parameters and discover sometimes unexpected solutions that might lie within a large parameter space. Students will use OpenStudio tools to configure an analysis scenario involving calibration, apply parameter sensitivity analysis to determine parameters of influence, and execute a calibration exercise where solutions are discovered. The course will be jointly taught by PSD’s Chris Balbach and NREL’s Brian Ball

Demo - New Features in OpenStudio v1.3.0May. 6th, 2014 **we apologize that the first 5 minutes have been clipped**
1) Support for modeling refrigeration systems:
OpenStudio 1.3.0 introduces drag, drop and configuration capabilities to model the energy use of common commercial refrigeration systems (e.g. display cases and walk in coolers), including cascading systems. While this is not unique, the ability to integrate the energy impacts of refrigeration systems into a building’s heat balance at an adjustable sub-hourly time step provides tightly coupled feedback for estimating the interactions between energy systems.
2) Support for modeling VRF HVAC systems
OpenStudio provides drag, drop and configure capabilities for modeling VRF (Variable Flow Refrigerant) HVAC systems and controls of varying complexity. VRF systems can be configured to operate in either a ‘heat pump’ mode, (where the system operates in either heating or cooling mode) or in a heat recovery mode (where indoor units can recover and exchange heat with other indoor units operating in the opposite mode). In addition, the outdoor units can be configured to be air, water or evaporative cooled. User defined performance curves (generated from manufacturers published performance data) can now be used to describe equipment performance.
3) Support for modeling supply and return plenum configurations
Forced Air HVAC systems commonly use plenums for supplying and/or returning the conditioned air. This release of OpenStudio allows users to define and configure supply and return plenums that serve multiple conditioned zones. Plenums are considered unconditioned thermal zones and are composed of children OpenStudio spaces. The plenum zones can leverage OpenStudio’s space type definitions for rapid object and property assignments.
4) Support for incorporating ASHRAE Advanced Energy Design Guides (AEDG) 50% measures
Thirty seven new OpenStudio measures from the ASHRAE K-2 and Small to Medium Office 50% AEDG have been added to the NREL BCL public measures library. These measures represent performance descriptions matching the published documents. As such, these measures contain the logic needed to easily & consistently transform OpenStudio models to evaluate potential savings from incorporating high performance building and system components. Easy application (drag and drop) of these measure to YOUR models will be demonstrated.
