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
- Thermal Enclosure
- HVAC Quality Installation (Contractor and HERS Rater)
- Exceptions for QA-Credentialed HVAC Contractor (December 2016)
- Water Management
- The target home/size adjustment factor used by ENERGY STAR
- Note: Revision 08 of EnergyStar V3 is now available and can be used by all partners effective immediately.
- 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.
- Download the WaterSense Excel tool for estimating the stored volume in hot water distribution systems.
- 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.)
