25. ARCH 600/611: Integrated Design
• We ask: “How do we integrate Building Design,
Engineering, and Construction practices?”
• We imagine, model, debate, test and interrogate
alternative ideas, …collaboratively.
• We utilize cyclical or iterative processes to
balance creative and expansive explorations with
honest critical appraisals of new possibilities.

29. Engineering: Innovations
• SMART house
• Courtyard
• CORE

30. Engineering: “Smart” House
We are currently
developing a physically
based model for the Solar
Decathlon
Visual Rendering of our Smart House

31. Engineering: Thermal Modeling
Our model takes into
account multiple heats:
• Sensible
• Radiation
• Ventilation & Infiltration
• Appliances & Lights
• Human Factor
Projected Temperature Profile for
Undersized A/C & Heater Unit

• Our projected forecast for the
Solar Decathlon will be dryer
than the typical comfort level
• By specifying 69°F, 40% RH,
and ventilation from outside
at 3 ACH, our projected water
consumption is 44.7 gal/day
as opposed to ~60 gal/day

34. Engineering: Future Work
• Hardware Testing
– Solar panels
– Battery system
– Sensors and actuators
– AC/DC busses
– HVAC systems
• Software Interfaces
