Enovative has proudly partnered with the U.S. Department of Energy’s “Zero Energy Ready Homes” (ZERH) Program as an ‘Innovation Partner’.  Among the requirements for a home to have this designation is to “conserve water and energy through an efficient hot water distribution system that provides rapid hot water to the homeowner.”  The AutoHot on-demand system meets this requirement and is proud to help to contribute towards our nations goals of zero net energy homes.

What is a DOE Zero Energy Ready Home? A DOE Zero Energy Ready Home is a home that meets all of the criteria found in the DOE Zero Energy Ready Home National Program Requirements. DOE Zero Energy Ready Homes are verified by a qualified third-party and are at least 40%-50% more energy efficient than a typical new home. This generally corresponds to a Home Energy Rating System (HERS) Index Score in the low to mid-50s, depending on the size of the home and region in which it is built.

All DOE Zero Energy Ready Homes are so efficient a renewable energy system can offset most or all annual energy consumption.

DOE Zero Energy Ready Homes must: 

  • Comply with ENERGY STAR for Homes and the Inspection Checklists for
  • Feature energy efficient appliances and fixtures that are ENERGY STAR qualified.
  • Use high-performance windows that meet ENERGY STAR v5.0 and v6.0 specifications (depending on climate zone).  The required U and Solar Heat Gain Coefficient (SHGC) values are shown below, effective 8/22/2016.

  • Meet 2012 International Energy Conservation Code levels for insulation.  In some states 2015 IECC insulation levels are required – see End Note #15 of the Rev.05 specs
  • Follow the latest proven research recommendations by installing ducts in conditioned space or using a high performance alternative as defined in the program specs.
  • Conserve water and energy through an efficient hot water distribution system that provides rapid hot water to the homeowner.
  • Provide comprehensive indoor air quality through full certification in EPA’s Indoor airPlus Program
  • Accomplish savings on the cost of future solar PV installations by following the PV-Ready checklist for climates with significant solar insolation.  This checklist references EPA’s solar electric guide.  (Note that the solar-hot water provisions of the checklist are no longer mandatory and can be found below with encouraged items.)
