WHAT IS ENERGY EFFICIENCY MODELING ANALYSIS?
Bennett, Power & Purvis International provides research and development computer simulation modeling analysis for manufacturers of quality building envelope products for the US residential and commercial fenestration market.
The importance of research and development is integral to the success of both simulation and thermal testing for the certification requirements of the USA. Using your products detailed assembly drawings, approved software from national certification entities and the most up to date approved glazing databases available, Bennett, Power & Purvis International can generate an EEMA (Energy Efficiency Modeling Analysis) through iteration (at your direction) prior to certification testing.
Our EEMA provides your in-house engineering department with reliable data that can be used to revise product design and reduce costs of shipping and certification testing by an approved testing laboratory. We provide a low cost preliminary research and development service that can be beneficial at any stage of design.
Research and development data generated using LBNL, NFRC, Passive House USA (PHIUS) and CMAST approved practices.
Architects/Designers & Independent Entities can take advantage of customized boundary conditions and environmental conditions to comply with unique weather environments throughout the North American continent.


What to know: How it works
Bennett, Power & Purvis International uses a four phase research and development process to analyze your product and provide evidence based, data driven and proven innovative energy efficient solutions for your product. Each phase may have several iterations but ultimately follow the same pattern.
Phase One: Glazing Assessment & Material Evaluation
Phase one consists of a glazing assessment and material evaluation employed in the product to be analyzed. Following receipt of all materials; glazing computations to include center of glass U-factor, Solar Heat Gain Coefficient and Visible Transmittance shall be conducted. Simultaneously, a material evaluation is conducted to ensure the correct material conductivity for each individual part modeled. Non-standard material or material not already certified by the NFRC are not approved for use within the USA (however, research & development material can be created using material data sheets provided by the customer).
Phase Two: Modeling Analysis & Initial Data
Phase two consists of modeling analysis and calculating initial overall product data. Once phase one is complete, one of our Building Envelope Energy Efficiency Consultants (BEEEC) will begin modeling the product, will insert glazing and generate an overall window value using standard NFRC sizes used for certification. The data will provide accurate, reliable values for comparison with manufacturers of similar products already in the marketplace.
Phase Three: Drawing Revision & Updated Modeling
Phase three consists of drawing revision and updated modeling. Following consultation with one of our BEEEC's (Building Envelope Energy Efficiency Consultant) regarding phase two results, the product manufacturer shall consider the results, implement revisions or adjustments and return to their BEEEC for updated modeling and revised data results. This phase may take several iterations to complete, in particular if products are trying to attain EnergyStar level performance.
Phase Four: Final Analysis Report
The final phase of the four phase research and development system is the final analysis report, the EEMA (Energy Efficiency Modeling Analysis) report. This report details the final product composition used to attain the listed U-Factor, Solar Heat Gain Coefficient, Visible Transmittance and Condensation Resistance of the overall product including the glazing and air spacer systems. The report will be delivered electronically to product manufacturer signed by the BEEEC.


Note: Our Energy Efficiency Modeling Analysis consulting service can provide your company with valuable data filled models that can diagnose points of strength, weakness and advise on revisions to product composition. Bennett, Power & Purvis International does not provide ENERGY STAR, NFRC, AAMA, CMAST or PHIUS Certification. Services and consulting for research and development purposes only.
