The R-2000 Standard is a voluntary national standard intended to encourage builder and consumer participation. The R-2000 Standard is periodically updated to ensure that R-2000 houses represent the leading edge of cost-effective housing technology. The requirements are intended to give the builder flexibility in the selection of construction techniques, building products, mechanical equipment, lighting and appliances. These technical requirements include both the performance goals and prescriptive measures that a house must meet to become eligible for R-2000 certification. The goal of the R-2000 Standard is to improve the energy efficiency of new houses without compromising either the interior or exterior environments. The technical requirements of the R-2000 Standard include measures for the efficient use of energy, improved indoor air quality and better environmental responsibility in the construction and operation of a house. The R-2000 Standard presents the criteria that a new house must meet to be eligible for R-2000 certification. The existing energy target formula in Appendix B is now multiplied by 0.5 to reflect the increased energy target.ġ.Cooling Systems (B13) – Now need to be ENERGY STAR certified.Removal of measures to avoid window condensation measures (A9a) since these are now covered under window performance requirements (4.4), and.Low-toxicity finishes (A3, A4, A5, A7, B1-4) – Re-phrased as third-party certified low-VOC (volatile organic compound) content, with additional choices for the third party.The MERV 13 rating is in line with that recommended by the R-2000 Committee for the 2014 R-2000 Standard. Air filtration (A2a) – Now need MERV 13 air filter instead of 10 percent ASHRAE average dust efficiency since the latter is not a common indicator in residential applications.Revisions to the minimum requirements for several Pick List items since some requirements had become obsolete.New requirements are in line with those recommended by the R-2000 Committee for the 2014 R-2000 Standard. Revisions to the water conservation requirements since the previous requirements were equal to or lower than code.The more stringent R-2000 energy target should ensure that higher performing windows are installed. Minimum requirement is now only double glazed, low-e coating, etc. Removal of energy rating requirements for windows since the specifications were out of date.
Revision of eligible buildings under “scope” to be more clear.Updated referenced standards where necessary.
