Yeah Munters and similar desiccant systems are a better option performance wise but I think $/CFM is too high for the developer. The architect won't give me the space either. My battle is for straight risers. It's only about a thousand CFM for corridors. I've got a unit with an enthalpy wheel for general vent which is much bigger. At least hot gas isn't frowned upon by 90.1 since it's site recovered energy. Electric and hot water reheat is the worst. I've seen jobs where that goes in and runs on the boiler because you can't get anyone to agree to something as easy as a desuperheeater on the chiller. Because the site isn't enormous code doesn't require a widely available equipment feature. Looking forward to IECC 2012/90.1-2010 which requires enthalpy recovery down to I think 30% OA.
