Steel Bar Joists by Canam Steel Corporation, an in-state, source located in Buckeye, AZ approximately 200 mi. north of A Sensible House. Thermal Storage As a backup to the slab and ceiling radiant masses, below slab soil will provide an energy sink for storage of and removal of sensible heat. Radiant Ceiling Cool water is circulated by thermostatically controlled hydronics. Radiant Floor Warm water is circulated by thermostatically controlled hydronics. Walls from Eterna Block have the following Advantages: ETERNA ADVANTAGES: * Thermal Performance * Termite Resistance * Will Not Mildew, Rot, or Decay * Fast, Easy Construction * Flexible Architectural Design (your own imaginations sets the limits) * Saves Dramatically on Heating and Cooling Bills * Conserves Natural Resources Such as Timber, Coal, Oil and Natural Gas * 700 Times Stronger Than Wood * Insurance Savings * Made in the USA Utilizing Post-Consumer Polystyrene Waste * Stucco and Inside Plaster Can be Applied Directly Without Need of Netting * Drywall Materials for Interior Surfaces Can be Adhered Directly * Fire Resistance * No Bug or Rodent Infiltration * Saving (perhaps) the Most Important Resource of All: Providing Edge Insulation for slab and below slab thermal mass Near Eternal Energy Storage Areas Window and Door Openings View More |

Energy (or Enthalpy) Recovery Ventilation (ERV) goes a little further than the HRV units, as this type of system also captures some of the humidity in the air to keep it on the same side of the thermal envelope that it came from.
So in cold winter climates, an ERV system transfers the humidity from the air being extracted to the incoming fresh (and dry) air to help keep the ambient internal humidity level at a reasonable value (between 40 and 60%) at all times.
In summer, the humidity transfer in an ERV reverses and the humidity in outside air is removed before it is injected into the home. This saves energy by reducing the load on air conditioning systems and/or dehumidifier. A high efficiency of humidity transfer would be around 70% but this value depends on the actual humidity on either side of the envelope.
One important note is that whatever you choose for your needs between an ERV & HRV, there will always be a power on/off switch. If your system is too noisy, you will likely turn it off for long periods of time even if you really need it. Choose a quiet ERV or HRV system and ensuring that it is installed properly to avoid the temptation of turning off a piece of equipment that represents both a financial and health investment.
