Option 1 energy simulation often requires hiring an energy-modeling consultant, adding a cost (although this ranges, it is typically on the order of $0.10–$0.50/ft² in North America, depending on the complexity). However, these fees produce high value in terms of design and decision-making assistance, and especially for complex or larger projects can be well worth the investment.
