Advanced Energy Engineering Technology Modeling Building Energy Systems Session 6: Building site and envelope

Topics covered in this class session: Building site and orientation The basics of zoning Energy properties of walls and roof Energy properties of windows

Building site and orientation Climate considerations Weather patterns Neighboring structures, vegetation and topography Solar orientation

The basics of zoning A modeling zone vs. an HVAC zone Aggregation of loads Zone by usage Zone by controls type Zone by solar gain Zone by perimeter or interior location Zone by fan system type

The basics of zoning (continued) Single-zone systems Multiple-zone systems Assignment of systems to plants

Building envelope—heat loss and gain Transmission through walls and other surfaces Heat loss to ground Infiltration R-value and U-value

Building walls and roof Insulation—wall and roof Structural materials Building skin materials Thermal bridging through studs Roofing (reflectance) Green (vegetated) roofs

Windows Window types and technologies U-values Infiltration Shading and solar gain

Interior spaces and features Unconditioned spaces Interior walls Above-ceiling spaces Exercise with eQuest in Lab or on other PC
