Abstract: Of the factors that influence wintertime occupant thermal comfort, two are often of primary concern around cold windows: overall low mean radiant temperatures and localized downdraft currents. To prevent these from leading to a thermally uncomfortable environment in cold climates, the building industry has traditionally applied perimeter heating – a system that can be costly to maintain and can result in greater energy use by delivering heat directly to the envelope. At present, the decision to remove perimeter heat in cases of highly insulated envelopes typically relies on conservative rules of thumb or time-consuming simulation methods. This paper expands upon the method to address this in Part 1 and makes it applicable to the variety of non-standard spatial conditions that exist in real buildings. Additionally, it presents methods to address temporal variations that result from different climate conditions, occupancy periods, and non-steady state building physics. Ultimately, these methods are combined into a plugin for the Rhinoceros 3D modelling interface, which is a primary geometry-modelling engine for architects, allowing goals of removing perimeter heat to remain relevant throughout the design process.
