An ASHRAE draft standard that describes a methodology to apply building energy modeling to the design process is open for industry input. ASHRAE Standard 209P defines minimum requirements for providing energy design assistance using building energy simulation and analysis.
Building Energy Modeling Software Is Brought Up to Date
October 24, 2014
The U.S. Department of Energy (DOE) announced that its EnergyPlus™ software, which models whole-building energy and water use, has been rewritten in the C++ programming language for improved performance. EnergyPlus lets users model design and operation alternatives — including HVAC system changes — on building energy performance.
It Is Currently Being Made Available to a Limited Set of Beta Testers

As many as 3,000 parameters can be specified when modeling a building’s energy use. Newly developed “Autotune” calibration software reduces the amount of time and expertise needed to optimize building parameters for cost and energy savings.
Modeling Software Integrates Energy Conservation Effects Across Many Buildings, Using Many Conservation Methods
September 29, 2014
Sandia National Laboratories’ Institutional Transformation (IX) model is helping the federal laboratory reduce its energy consumption and could help other large enterprises do the same. The IX model allows planners to experiment with energy conservation measures, such as replacing old HVAC systems, before making expensive changes.
OpenStudio Enables Modeling of the Energy and Water Usage Performance of Buildings
November 19, 2013
Performance Systems Development (PSD) is the first commercial organization approved by the National Renewable Energy Laboratory (NREL) to deliver OpenStudio® training courses for building professionals, software developers, and utility administrators.
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Energy Modeling Conference, scheduled for Oct. 1-3, 2012, in Atlanta, aims to advance attendees’ abilities to accurately model and simulate a building’s energy use through some 40 presentations, keynote speeches, and networking.
