ABSTRACT: In the heating dominated climate of Asheville, North Carolina, maximizing solar gain in a new Visitor Centre for the Blue Ridge Parkway by using segmented Trombe walls along the south façade became the driving force behind the building design. This paper explores the simultaneous use of three analytical methods: hourly 'lumped node' whole building energy analysis (using eQUEST - a DOE 2.2 interface); full-field thermal analysis with RadTherm (heat transfer software) and nPhase (Computational Fluid Dynamics); and hand calculations using the Load Collector Ratio (LCR) correlation tool. These tools were used together to investigate the full impact of the Trombe walls on both energy savings and thermal comfort. Although we performed CFD simulations for summer and fall conditions, this paper will focus on the winter simulation.
