OpenStudio 1.9.0 Release

OpenStudio 1.9.0 is now available for download from the OpenStudio website.
Notable new features include:

- The addition of a substantial number of new HVAC features. Among the new features are three entirely new categories of HVAC capability beyond the routine component additions. The first new category is a family of availability managers that allow for detailed control over the air system period of operation. With these new availability managers, it is possible to have detailed control over night cycling, night ventilation, optimum morning start, temperature-based on/off and more. The second new category of HVAC capability included in this release is another family of control related inputs known as plant operation schemes. With plant operation schemes, it is possible to control the sequencing of plant system supply components relative to one another while considering ambient conditions. Third, OpenStudio has added support for dual duct air based systems.
- A number of enhancements in areas beyond HVAC capability particularly to the OpenStudio application and the Measure ecosystem.
- A number of bug fixes and performance improvements.
