NTREG Member Projects - The Neukranz Residence

The Bill Neukranz residence is an ideal example of what can be done to improve home energy efficiency. Starting with a conventional tract home, and working gradually over several years, Bill and his family have an incredibly comfortable home. As a result of their extensive energy efficiency measures, the Neukranz family enjoys an average $47 monthly heating/cooling cost in spite of Dallas' hot climate, and the Neukranz family's use of electric heat in the winter.

What made this possible? Extremely efficient (24 SEER / 5 COP) geothermal heat pumps - one mile of underground pipe, and no outside equipment to wear out. HVAC efficiency is further enhanced with four independent zone air distribution, variable-speed air handlers (improves humidity control), and two-stage compressors. Sheet metal ducts inside the attic are insulated with R-8 foil backed insulation, and have all the seams sealed. Programmable thermostats adjust at different times of day, saving money and reducing energy use at peak times. Large ceiling fans in every room prevent air stratification and reduce demand on the HVAC system. All lights are compact fluorescent lamps - no incandescents are used, netting approximately $400 per year in energy savings. An extensive home automation system assists with comfort, efficiency, safety and security. All windows are double-pane with thermally-broken anodized aluminum frames. All have thermally efficient shades to block out hot daytime heat. Minimal windows on the west side, large windows on north and east side, and an open floor plan provide ample daytime illumination.
