We own and are building on lot 19 which has a street address of 263 )6 Diamond H Lane. Whave designed and are implemen.ting a couple of unique approaches and systems into this home, therefore the purpose of this letter is to briefly introduce theseapproaches to you and io identify our current status, Please find enclosed the Project Drawings and, Project Plan and Primary Contractor Scope of Work and Specification. I am the General Contractor for this project and Jim Kelly of Kelly Construction i.n Rigby Idaho is the Primary Contractor. Relative to the mechanical systems for this home, Justin Johnson of Sprinter Heating and Hydronics, LLC is our primary heating contractor and is providing and instaili.ng a ground sourced heat pump supplied hyd.ronicslradiant floor heating system. Additionally, Doug Johnson of Wiemer Heating anAirair conditioning system. Some of the informationd Conditioning will be providing the central on these systems xn the enclosed Project Plan and Pn"nlary Contractor Scope of Work and Specification has changed slightly and the updated plansaare presented below. P ip There are several unique energy saving approaches designed into this home. Specifically the use of 1) Insulated Concrete FQrzxis (ICF) block exterior walls providing an R-30 insulation Value, 2) R-50 ceiling insulation,, 3) Low -E argon wdoors,indow, 4) steel insulated ground water sourced heat pump heating and cooling system., and 6). grey water heat recovery system. The following figures provide a basic block diagram of HVAC system.

The Grey W0ager Heat Recovery System is modeled after s�xnilar systems currently ire use in man energy e.ff czent Karnes. From a0 plumbing perspective, thYs system has been. reviewed and approved by the Stale of Idaho Plumbing Bureau in Meridian and the installation of the sub floor pipi'ngand grey water tank k�as been insp�ected andappxoved by Adarx� Bowcatt, our state 1�.�mbin� ins ctor. Basically the conceptis to use wa�nn to hod wane(grey)water from the home pprimary hot wa ter sources to warm the water entering the heat pump system. If the input water temperature to the heat pump can be raised even a few degrees, the efficiency of the heat pump system Is szgnificanty improved. Therefore, we have piped separately from the other peptic wates, grey water from the home's clash washer, bath tub, and 3 showers to a 300 -gallon direct buried' poly tank. This grey water gravity feeds out of the poky tank into the home's septic system. A backwater valve -prevents the black water from entering the grey v�at�r tank, A1sQ� the tank and lines wi11 be vented per rode requlrements.
