GreenTree facilitates dynamic thermal modelling which is an advanced way to simulate the thermal environment of a building element. The simulation captures the heat transfer process and thermal capacity into and through the window frame. This understanding allows us to assess opening s thermal behaviour and that, precisely, is responsible for temperature and humidity difference between inside and outside of the building environment. GreenTree offers these services using the following tools:Computer Thermal Simulation Window 5 Center of Glass Therm 5 Frame and Glazing WUFI Pro 4 Vapor Transmission Thermal Stress Analysis Glass Stone Framing Sealant Joints Window 5 Software Center of Glass Energy Performance Monolithic Glass IG Units Insulated Spandrel Panels
