Overview

The most significant new feature in OpenStudio 1.8.0 is the addition of many new HVAC objects to the OpenStudio Model. The new types available in 1.8.0 include HeaderedPumpsConstantSpeed, HeaderedPumpsVariableSpeed, TemperingValve, CoilPerformanceDXCooling, CoilCoolingDXTwoStageWithHumidityControlMode, CoilSystemCoolingWaterHeatExchangerAssisted, CoilSystemCoolingWaterHeatExchangerAssisted, GroundHeatExchangerHorizontalTrench, ThermalStorageIceDetailed, ChillerAbsorptionIndirect, ChillerAbsorption. These new types are available through the OpenStudio API for use in measures as well as in the OpenStudio Application. Advanced tutorials on how to use each of these new objects may be available in the future.

Additionally, the ability to import IFC into OpenStudio via BIMserver has been added by the CBEI group from Penn State University. A tutorial on how to use this new functionality is available at http://nrel.github.io/OpenStudio-user-documentation/tutorials/tutorial_ifcimport/.
