12 years CCDS Cincinnati Ohio, UC Engineering Science college and CO-Op Professional Practice with lab test equipment design and machine shop to Vacuum Lab specialties testing high temp and reports through 1980. Thermal load studies with A/C prospecting from 1976 to sizing, design and implementation and consulting to over 140 contractors and engineers and oem process and manufacturing, while residential hands on over 1700 systems of Geothermal Heat Pumps, loop and well and data acquisition specialties to date. International consults and to customers in three states. SOLAR design and implementation started in 1980. Alos selling from the Solstar(tm) systems and heat load studies format they trained salesfolks to use, sizing GT Loops were not only correct since then, but warmer-enough that one actually realized the efficiency and heat as for 35 to 36f ratings in northern Ohio 51 to 52f soil temps at 18ft and those 8ft depth temps about 5f cooler, then. Solar in 1980 that some have finally been removed in 2012 and 2013, were Air Collectors (detailed design in another RE article, available. Filtered Air: Diverted temperature control and usage; recirculated to fancoil for then 33w to 60w water recirculation for Hot-Water Heating; some six 8x3ft collectors "cooked" 2200 living area -standard retrofit 1980 old home well enough for over all near 50% heat (gas) savings. That revealed at least three things: gas/sized/convestors/ was under 55% net cyclic annually efficient (100k boiler); and that home only needed less than 30,000 btuh at zero f , with standard construction (at times of similar air infiltrations and other retrofit qualifier's present); and putting a return air at the coldest end of the space and the supplies from the ceiling streaming-air downward (bent-fin-registers) rotated ceiling-floor air temp differentials to 1-degF (!) I am always asking where heat energy is being used or going-to has been leading reviews of others to find out what truly is a best of the best "Best of the Best" for a more comprehensive analysis, without hidden investment promotion, but more so some better exposure of just what is. GUZINTA's= That waste energy...? Guzintas where? Construction and insulation envelope consults for a better Utility Rate, a better Building, a better Distribution of the Energy Dynamics and air and/or fluid - radiation to heat energy recovery- and -reclamation and transfer. Family of Grand's ideas and their many many working patents in use today, and artists -professionally as teachers and have lead to simply looking for how to apply a statement: "Look for the design in everything." It has been variously interesting working with folks and designs of Industrial Chillers, Process Energy Exchange from "The Source" or "The Heat Sink" to also since 1980, ground loop GTHP GHP Geothermal Heat Pump sales, installation among reviews, and troubleshooting. Homes are heating 20f below zero with standard insulations below 13 btuh per square-foot areas (retrofits near that with ducting/distribution modifications) . Tiny and sustainable renewable energy systems of Earth Coupled Systems with AND WITHOUT heating or cooling units having compressors or absorption systems seem better than just matching equipment to some existing, still-seeing-thought-necessary by others, to retrofit and new that needs a little more 'adjustment' of say some air or fluid dynamics. Many mentors back to the 1970's with ground loop studies have been most helpful. Through 20111, OEM representation of a most innovative GT-HAVC (and private-label to industrial names using their systems) allowed for many meetings for design to troubleshooting and assisting in OEM design change implementation. Engineers have benefited from loop redesigns from 1997 - to date. A mention of Ohio mentors: Dr. John Jones and PE ME Michael Rice (modified Comfort Maker/Friedrich- as well) and Dick Sharp, Dayton; David Hart OEM, and Tom Dellinger, OEM, Columbus; Sugar Bear Industries/Solargy, and to date implementing along side Carrier/Bosch, and other top promoted brands, as well as industrial and commercial chillers: So far a real best in/of total annual usage (with Heat Recovery in Cooling Modes for 100% Hot Water heating on demand as well, of Renewable and Sustainable synergistic energies and design for total usage dynamics seen for 20+ year lifecycle considerations of so far of about any "Best of the Best" who has built for one of those 'Best' and has 1881 patents, I have installed for since 1993, The Hydro-Temp Corp, Arkansas; and those being of the first Net-Zero school and a largest surgical center in the country, as well as the Federal Reserve Building, to be seen at Hydro-Temp.com and reviewed at Energy Star most efficient geothermal, + then add the HW Heating recovery in cooling mode, with all pumps off to source loops, so that all the Cooling Mode heat transfers to a HW tank or process in 199% heat on demand as well as reclamation.
