Who performed the simulation analysis?
Architect - Internal Sustainability Personnel
What tools were used for the simulation analysis?
OpenStudio + Eplus
What phase of the project was analysis conducted?
What are the primary inputs of the analysis? Orientation, Location, Weather file, Window-to-wall ratio, Double Glazing, SHGC, VLT, R-Value Wall, Plug Load Density, Dayligthing Sensors, Shading, Light Power Density, HVAC system
What are the primary outputs of the analysis? Overall predicted Energy Use Intensity (pEUI), Heating, Cooling and Lighting pEUI, solar radiations (kWh/m2), seeking for the best scheme performer
List the investigations questions that drove your analysis process.
What is the best massing to the whole building energy use of the project and what is the magnitude impact of various efficiency measures (Orientation, Window-to-wall ratio, Glazing Type, Solar Control, Shading Devices, Daylight Sensors, Light Power Density, Thermal Resistance of the assembly, HVAC system)?
How was simulation integrated into the overall design process?
How did you set up the simulation analysis and workflow?
The geometry was modeled in Open Studio. The parametric energy analysis was ran with jEplus. The outputs were generated by Adobe Photoshop, Excel, Power Point.
How did you visualize the results to the design team? What was successful about the graphics that you used to communicate the data?
The results were shown to the design team on a power point explaining the inputs, outputs and magnitude impact of the energy conservative measures.
Most importantly, what did you learn from the investigation? How did simulation and its outputs influence the design of the project?
