EnergyWise Roof Calculator Online
Clicking the "I Agree" button below constitutes your acceptance and acknowledgment
of the terms and conditions set forth below (the "License Agreement"). If you do
not agree to the terms and conditions set forth in the License Agreement, you may
not use the NRCA EnergyWise Roof Calculator software application (the "Calculator").
Once accepted, the License Agreement will govern each and every use of the Calculator.
By accepting these terms and conditions, you acknowledge and agree as follows:
- Each time you use the Calculator, NRCA will grant you a one-time personal, nontransferable
and nonexclusive license to use the Calculator. This license is valid for one-time
use of the Calculator and automatically terminates upon delivery of the written
report generated by the Calculator application (the "Report").
- The Calculator, the contents of the Calculator and the Report are copyrighted by
NRCA. The license granted above is not a sale, and this License Agreement does not
give you any rights to copyrights, trademarks and/or patents with respect to the
Calculator.
- You may not copy, alter any of the text, or manipulate any aspect of the Calculator
or the Report.
- Neither NRCA nor the organizations supporting the Calculator (collectively, the
"Supporting Organizations") "approve" or "endorse" any specific products, methods,
companies, practices or sources of information referred to or suggested by the Calculator.
You should not reference the Calculator or do anything that in any way would imply
such approval or endorsement.
- The calculations used in the Calculator are based on accepted practices, including those
defined in the American Society of Heating, Refrigerating and Air-Conditioning Engineers' (ASHRAE)
Fundamentals Handbook; ASHRAE 90.1 "Energy Standard for Buildings Except Low-Rise Residential Buildings,"
1999, 2004, 2007 and 2010 Editions; ASHRAE 189.1 "Standard for the Design of High-Performance Green Buildings,"
2009 Edition; International Code Council's International Energy Conservation Code (IECC), 2006, 2009 and 2012
Editions; and International Code Council's International Green Construction Code (IgCC), 2012 Edition. The
Calculator may only be used for determining energy calculations pursuant to the "Prescriptive Building Envelope Option"
under ASHRAE 90.1 and ASHRAE 189.1 and the "Specific insulation requirements (Prescriptive)" option under
the IECC and IgCC. For more specific details and information, refer to ASHRAE 90.1 and ASHRAE 189.1, IECC and IgCC.
- The Calculator is intended to be a simplified guide. Complex energy calculations,
such as solar heat gain and exterior shading considerations, are beyond the scope
of the Calculator and intentionally have been excluded. For complex energy evaluation
calculations, including evaluations of the entire building envelope, building usage,
or changes to heating and air conditioning equipment, you must consult the ASHRAE
Fundamentals Handbook or an experienced mechanical engineer.
- The Calculator relies on your input to generate a Report intended to provide a graphical
method of constructing roof assemblies to evaluate thermal performance and estimated
energy costs under normal operating conditions. The Report applies only to the specific
building identified by you and relies solely on the input supplied by you. Any misinformation,
miscalculations, mistakes or changes in the information you enter into the application
may affect the results, accuracy, reliability, safety factor and/or other aspects
of the Report.
- By accepting the terms of this License Agreement and using the Calculator, you specifically
acknowledge that neither NRCA nor the Supporting Organizations is undertaking to
render specific professional advice. You must rely solely on your own judgment or
consult a technically competent roofing professional and/or an experienced mechanical
engineer to determine whether the information included in the Report is appropriate
for your particular purpose. Neither NRCA nor the Supporting Organizations assume
responsibility for any decision made by you relating to the suitability or use of
the Calculator or the Report.
- Neither NRCA nor the Supporting Organizations make any guarantee, representation
or warranty, express or implied, at law or in equity, and NRCA and the Supporting
Organizations expressly disclaim any and all such guarantees, representations or
warranties whatsoever, as to the validity, accuracy or sufficiency of the information
supplied by the Calculator and/or the Report and assume no responsibility or liability
in connection therewith. NRCA and the Supporting Organizations assume no liability
or responsibility in connection with the use or misuse of the Calculator or information
included therein or supplied thereby or in connection with any modifications to
or adaptations of the Calculator and/or the Report by you or any other party and
expressly disclaim any such liability or responsibility.
- You expressly assume all risk of loss, harm or injury resulting from the use or
misuse of the Calculator and/or the Report. Additionally, the suggestions and information
provided in the Report may not be appropriate in all instances and requires verification
and use by technically competent roofing design professionals and/or an experienced
mechanical engineer.
