Can a home be beautiful, powered entirely by solar energy, use sustainable heating and cooling systems and save it’s owners roughly $3,500 a year? Why, yes it can. Just ask Joanne Coons, who built her award winning, single-family, Net Zero Energy Home in 2010. Sustainable Woman Joanne talks Net Zero standards, efficient appliances and goods, her […]
Factors such as space limitations are forcing engineers to utilize deep boreholes to meet design requirements for Ground Source Heat Pump (GSHP) systems.
In such cases, hydrostatic pressures must be considered to ensure successful installation can take place. This short course, led by expert Ryan Carda, P.E., focuses on the necessary calculations along with the recommended […]

Low Ambient Air-to-Water Heat Pumps: An emerging renewable heat source for North American hydronic systems.
Electrically powered heat pumps, in many varieties, are destined to play an increasingly important role in heating and cooling buildings around the world.
Heat pumps capture low grade heat from solar-resupplied sources such as outside air and soil several feet below the earth’s […]
Expert Instructor Ryan Carda discusses vertical boring systems, horizontal ground loops and Energy Recovery Ventilator ducting on the IGSHPA Certified GeoExchange Designer (CGD Plus) Training discussion board…
Student 1: Would you say that the addition costs associated with vertical boring are greater than the cost of extra piping necessary for a horizontal system?
Ryan Carda: To a point – HDPE pipe itself is […]
