Heat Transfer Simulation Tools
These tools can be used to calculate heat transfer that occurs in building components such as windows, walls, foundations, roofs, and doors.
TOOLSBerkeley Lab WINDOW ToolsFor analyzing window thermal and optical performance. WINDOW5 is a state-of-the-art, Microsoft WindowsTM-based computer program developed at Lawrence Berkeley National Laboratory (LBNL) for use by manufacturers, engineers, educators, students, architects, and others to determine the thermal and solar optical properties of glazing and window systems.THERM ToolsFor analyzing two-dimensional heat transfer through building products. THERM is a state-of-the-art computer program developed at Lawrence Berkeley National Laboratory (LBNL). THERM can be use to model two-dimensional heat-transfer effects in building components such as windows, walls, foundations, roofs, doors.COMFEN ToolsFor calculating the heating and cooling energy use, and visual and thermal comfort, of commercial building facades. COMFEN is a tool designed to support the systematic evaluation of alternative fenestration systems for project-specific commercial building applications. It uses Energy Plus as a simulation engine to dynamically simulate the effects of key fenestration variables on energy consumption, peak energy demand, and thermal and visual comfort.
