DESCRIPTION:The subject of this talk is the design analysis process of an 
 experimental solar house\, driven by the overarching goal to obtain net-ze
 ro energy performance while being functionally optimal and architecturally
  ambitious. The house was commissioned to participate in an international 
 solar home competition sponsored by the Department of Energy and the Natio
 nal Renewable Energy Laboratory in October 2007. Called the Solar Decathlo
 n\, this design-build competition invites 20 international universities to
  design\, build\, and operate an 800 sq.ft. all-electric solar powered hou
 se within a tight set of performance criteria. All participating teams are
  required to transport their house to Washington DC for a specified week (
 October 2007 in this case). During this week each house is judged based on
  a range of subjective and objective contests related to architecture and 
 engineering strategies.\n\nLed by four faculty members\, the Georgia Tech 
 design team consisted of a multi-disciplinary team of over 100 students fr
 om architecture and engineering departments. Today’s talk looks at the h
 ouse as an in-vitro case study of design evolution driven by a unique set 
 of objectives that necessitate detailed analysis at various stages. The pr
 esentation outlines the major milestone decisions in the evolution of the 
 project. It does so from the building performance analysis perspective wit
 h emphasis on the use of simulation. \n\nThe presentation will show three 
 distinct phases of design analysis. The first phase is based on using roug
 h estimates of the house’s components to inform meta-level design compon
 ents and system choices. In the second phase\, this model is replaced with
  a lumped finite element model for fine-tuning design elements. The “lum
 ps” in the finite element model represent building systems which are rep
 laced as needed when more detailed representations of their components bec
 ome available. In the third step\, the simulated systems are replaced by t
 heir real world counterparts. The substitution of a simulated component wi
 th a real component is enabled by special interface modules and suitable d
 igital/analog interfaces. The third step results in a calibrated simulatio
 n model of the house synchronized with an optimal controller that manages 
 the interaction of all house components and also guides strategies for max
 imizing objective scores during the competition period.\n\nwww.solar.gatec
