   I'm not sure you could do it, at least not without cutting services. I sometimes help out the guy I use, who runs two places. One of their problems is that their air conditioning can't handle the heat load in the summer when all the hair dryers are running. They use a LOT of electricity when compared to a normal user of a similar amount of square footage.

   When you start to look at places that have high occupancy densities and high energy use/sf, the self contained “net zero” concept almost breaks down. Until someone builds a heat pump hair dryer, you are just going to need a bunch of energy production.

   What is the benefit of having that production within the footprint of the facility vs buying energy from an offsite facility?

   To think about this another way, net zero is easily achievable using existing approaches if you just limit the number of clients served. What could be wrong with such an approach?

   Hrm...now you got me thinking about a heat pump hair dryer. I’m thinking Chiltrix air source hydro with a mini hydro blower unit on flexible lines...

   Given the relatively high cooling loads and DHW requirements, a heat pump water heater could be a good option.

   我想说负面的效益和公司时更少nsider that "net zero energy" doesn't accomplish this (it typically buys lots of energy from offsite - it just pays for it with energy at another time).

   Forget "net zero energy" and focus on "green" on a macro basis.

   A good start for summer hair drying efficiency would be to capture and remove the heat.

   I like the heat pump water heater idea. The salon places use a lot of hot water too, so a heat pump water heater would essentially harvest some of the otherwise lost heat from the hair dryers. An added bonus would be additional space cooling in the summers.

   Heat pump water heaterS are definitely in.

   Im thinking separate room/space for the darth Vader drying hood things. Then you could dump some of that heat outside.

   ALTHOUGH in winter that damp heat would be nice to redistribute throughout the building.

   We're only talking 1000 sq ft here 3 chairs more than likely. Not a New York size 25 chair establishment.
