In the last post I introduced the complexity of adding PEX water supply and return pipes through the periphery of the house. But it is all not negative for the home builder. Not only the business advantages to differentiate with green technology this idea also brings about a lot of complexity reduction for the builder. The builder now requires fewer suppliers and contractors. Read on.  

Heat rejection is a prime concern with distributed residential AC as described in this website. Ideally, I like to be able to reject heat to geothermal water cooled system. The design and implementation of this has significant impact on residential construction and building codes. I like to get feedback from building professionals. Geothermal water cooled system requires a PEX pipe circuit running throughout the house. The reason is that in a typical house of 2500Sq. Ft there are about 20 smart microAC units located in almost every wall in the house. This requires water to be circulated to almost every wall in the house.
