This site is meant to illustrate the capabilities of the displacement and cross ventilation models that have recently been implemented in EnergyPlus. It contains both technical and practical information.
The site contains the following sections:
- Introduction: this section provides a general overview of the site contends and purpose.
- Displacement Ventilation: this section presents information on the fluid mechanics of displacement ventilation including advantages / disadvantages and design advice.
- Cross Ventilation: this section presents information on the fluid mechanics of cross ventilation including advantages / disadvantages and design advice.
- Design Example: in this section a virtual design example is introduced and analyzed using different ventilation strategies and cooling systems. The different cases are presented in the section labeled NAT CV, NAT CV, etc. The following acronyms are used:
- NAT: naturally driven ventilation.
- SC: natural displacement ventilation powered by internal buoyancy sources and a solar chimney.
- CV: cross ventilation.
- DV: displacement ventilation.
- MX: mixing ventilation system
- HYB: hybrid cooling system using ventilation air and a chilled floor
- MEC: variable air volume system using mechanical ventilation and "mechanical" cooling
- Results Summary: this section contains an overview of the results of the design example analysis sections.
- Geometry: in this section the basic details of the building geometry are presented along with a schematic table with a synthetic description of the cases including EnergyPlus input and geometry files.
- Weather: the analysis performed considers three locations in California (San Francisco, Los Angeles and San Diego), this provides download links for the files and presents the periods considered in each location.
- Simple Interface: this section contains two excel based EnergyPlus interfaces that can be used for building geometry and systems input.
