Identifies energy efficiency measures through auto-generating OpenStudio and EnergyPlus building models
November 21, 2016
The new simuwatt energy assessment application and platform is designed to make building energy modeling quick and easy. Building professionals can create an energy model directly from field data collected using simuwatt on the web, Windows Surface, and Apple iPad tablets.
The traditional, and still dominant, uses of energy modeling are all associated with building design, such as HVAC system selection and sizing and code compliance. But energy modeling has impactful post-occupancy uses as well.
Standard is open for public comment until May 9, 2016
