Answer the following statements true (T) or false (F)
1. Good indoor environmental quality results in real economic benefit from productivity. These benefits should be included in life-cycle cost analysis. 2. Reducing load will reduce construction cost through smaller HVAC systems. However, there will generally be an offsetting cost for features required to effect the load reduction. 3.
