Your loads were determined by decisions you made weeks ago.
◦ Which single earlier decision had the largest effect?
◦ If you could go back to Week 3 knowing this, what would you change?
◦ Who on a real project team should have raised this, and when?
Occupant comfort is not the same as air temperature.
◦ What else determines whether an occupant feels comfortable?
An occupant’s comfort is also determined by radiant temperature, humidity, air speed, and an individual person’s location within the room (i.e. standing next too a cold or warm window). It also depends on ventilation and indoor air quality, because a lack of fresh air can lead to stuffiness.
◦ Which of those can your model predict, and which can it not?
The model can predict indoor air temperature and see how ventilation, solar radiation, and thermal mass impact the temperature. It only looks at ventilation as a source of heat, not as a supply of fresh air. It doesn’t show how the temperature can vary based on a person’s location in the room, or how humidity and radiant temperature can change throughout the room.
The Bay Area has a mild climate.
◦ Where in your typical floor, and where else in your building, is mechanical cooling genuinely necessary?
◦ What would it take to eliminate it, and what would that cost the occupants?
You computed loads for one typical floor.
◦ Which floors in your building would have a different loads, and why?
◦ Would the system you modeled for your two units still work on those floors, or what would you change?
You were told not to agonize over duct connections.
◦ What is the difference between a detail that matters now and one that can wait?
◦ How would you know you had deferred something you should not have?
