What kind of graphic is this? Radar Chart
What are the primary inputs of the analysis that the graphic describes?
Building(space) geometry, envelope properties, temperature/humidity set point schedules, people/lighting/equipment loads and schedules, TMY weather file.
List the primary outputs/metrics that the graphic describes?
Design primary air flow rates of active chilled beam
What is this graphic showing?
The graphics are created base on an in-house HVAC design assist tool, the 5 radar charts illustrate the design primary air flow rates driven by outdoor air, sensible cooling, sensible heating, and latent cooling accordingly. In ACB design, the outer most primary air flow in the radar chart would anchor the design primary air flow rate and used for equipment selection. We analyzed different strategies that would reduce the design primary air flow and leave only the ventilation air as the driver, the goal is to achieve a fully decoupled ACB system design.
How did you make the graphic?
The calculation is performed by a in-house HVAC simulation tool. Graphics are made with Excel and Photoshop.
What tools did you use to create the graphic?
What specific investigation questions led to the production of this graphic?
How to achieve a fully decoupled active chilled beam system design and save the most energy and first cost.
How does this graphic fit into the larger design investigations and what did you learn from producing the graphic?
The graphics allows us to design the ACB systems with greater insights on the drivers of the design primary air flow rate and think about strategies to minimized the air flow rates.
What was successful and/or unique about the graphic in how it communicates information?
Integrate architectural design strategies into HVAC design.
What would you have done differently with the graphic if you had more time/fee?
Investigate more architectural design strategies and the interactions with HVAC system design. Fine tune the equipment selections and balanced out the design through architectural design features, considering both energy cost and equipment cost.
