Smartlux on Greenpark

    • This luxury home by M Street Homes of Houston, Texas, boasts a unique high-performance HVAC system and U.S. DOE Zero Energy Ready Home certification.
    • This 4,500-square-foot, tri-level home will cost its owners less than $1,500 to heat and cool annually.
    • This high-efficiency home achieved a Home Energy Rating System (HERS) score of 32, far lower than the 100 HERS score typical of new homes.
    • Roof-mounted photovoltaic panels use free energy from the sun to generate electricity.
    • High-efficiency appliances like an ENERGY STAR-rated dishwasher, refrigerator, and freezer contribute to low energy bills.
    • EPA WaterSense-rated fixtures help reduce water and energy use.
    • Low-/no-VOC paints and finishes help provide a healthy indoor environment.
    • On-demand hot water pumps speed hot water to faucets at a push of a button to limit water waste and save energy.
    • The balanced fresh air system includes a filtered fresh air intake that is wired to the central HVAC system with timer controls, while exhaust fans in the kitchen, bathrooms, and laundry room pull stale and moist air from the home.
    • The home uses waste heat from the gas-fired tri-generator to provide nearly all the hot water for a family of four, with a high-efficiency heat pump water heater for backup.

      "We are susceptible to allergies that cause sinus problems for both of us. The special air filters seem to remove allergens, as we have had no problems with allergies since we moved into the house." – Homeowner Steve

      Home owner (or occupant) Testimony
      One of the most important features is having so many windows to let in the light and view without worrying about heating up the home. It is very comfortable throughout the home, and the bonus is that all of the attic space stays comfortable due to the special foam insulation.
