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. A proposed air conditioning system costs $3,000/ton. The capacity of a 1000-ton system is reduced by 50 tons through load management. The cost savings in HVAC will be $150,000. 4. If the average cost of electric is $0.10/kWh, and a cooling system uses 1.6 kW per ton of cooling, the cost of one ton-hour will be $0.10 × 1.6, or $0.16 per ton-hour.
