Preliminary Questions

Areas of inquiry: Air Quality, Thermal Mass, Solar Gain.

• What are the levels of chloramine in the air? (What effect does the large HVAC system have on air quality?)
• What causes the ambient temperature differential between the East and West halves of the room?
• Does the solar energy entering through the East and South windows contribute significantly to the building's heat gains?
• Is the building internal-load dominated?
• (What is the role of the water's mass in the heating needs of the building?)
• Is the air temperature driven by heating the air in the HVAC system, or by heating the water?
• Does the concrete slab act as a thermal mass? (i.e. does it contribute passive solar heating?)
• How many air changes per hour (ach) does the HVAC provide?
• Is there a heat exchanger in the HVAC system to recover heat from the air?
• What would a 3D thermal map of the building volume look like (x, y, and z measurements), especially in response to pool temperatures and solar exposure?
• How would covering (insulating) the pools at night affect the heating needs of the air and water, especially in comparison with the needs when the pool is uncovered?
• Is it more efficient to heat the air directly, or only to heat the water directly, and heat the air through conduction?
