Pivotal Announces New APEX Simulation and Analysis Platform

Pivotal Energy Solutions, LLC, based in the Phoenix Arizona metropolitan area, has announced a new simulation solution targeting the residential new construction market. APEX, a simulation solution that utilizes the U.S. Department of Energy’s EnergyPlus simulation engine and OpenStudio-ERI calculation platform, enables the simulation of residential energy model data to generate energy rating index (ERI) and consumption results. APEX results may be used for a variety of purposes including eligibility for 45L tax credits, Fannie Mae and Freddie Mac mortgage-backed security offerings, performance-based energy code compliance, sustainability/ESG reporting, and incentive calculation for utility incentive programs.

APEX offers unique functionality for energy raters and modelers, utilities and other energy efficiency program sponsors, home builders, code officials, and downstream stakeholders to both validate energy models against specific program requirements and simulate those models using standard program reference homes and/or custom, program-specific user defined reference homes (UDRH’s). APEX’s input validation functionality – which can be run independently from simulation – performs automated checks on the energy model input values to ensure they not only fall within prescribed bounds but are also internally consistent with other home characteristics and specified values. This functionality enables energy raters and modelers to identify and correct issues with their energy models prior to simulation or submission to energy efficiency program administrators.

APEX supports the simulation of energy models using the U.S. Department of Energy’s EnergyPlus and OpenStudio-ERI simulation engine and calculation platform. The EnergyPlus/OpenStudio-ERI solution is an open-source offering from the National Renewable Energy Laboratory (NREL), meaning that the source code of the software is accessible to anyone to read, examine, and critique – proprietary simulators do not support the same level of transparency. The EnergyPlus/OpenStudio-ERI platform provides consistent, accurate results for an industry under increasing scrutiny due to the availability of 45L federal tax credits for homes meeting specific ERI targets and conforming to federal energy efficiency program requirements.

APEX’s support for standard reference homes and custom user defined reference homes (UDRH’s) also enables unique flexibility within the industry. Using a single energy model, APEX can perform simulations using any number of program-specific reference homes or custom UDRH’s. For example, eligibility for ENERGY STAR, DOE Zero Energy Ready, performance-based energy code compliance, and utility program incentives can all be determined through a single submission to APEX. Energy efficiency program developers and sponsors can also use APEX to enforce program requirements using the APEX input validation and custom UDRH capability to define energy efficiency targets and incentives as their programs evolve. APEX supports energy consumption and ERI calculation for ENERGY STAR, DOE ZERH, and virtually any utility and/or municipality performance-based program.

Bob Burns, co-founder of Pivotal, said, “We’re very excited to be offering this new solution to the industry. APEX enables utilities, builders, code officials, and downstream markets that rely on the modeled performance of homes to utilize a single, DOE-funded, open-source simulation engine, which we believe is a huge benefit to multiple stakeholders. APEX can serve as a ‘normalization tool’ to enable energy raters and modelers to use whichever modeling software they prefer while also providing a single, standard set of results generated by re-simulation of the original input data with EnergyPlus.”

The APEX simulation solution is currently integrated into Pivotal’s AXIS cloud-based platform used for the administration of and participation in a variety of “green” and energy efficient buildings programs. In the near future, APEX simulation and analysis solutions will also be offered as stand-alone cloud-based solution accessible through an application programming interface, or API, for easy integration into existing utility program infrastructure and back office applications.

Burns concluded, “APEX is a very powerful solution being introduced at exactly the right time to meet the residential new construction industry’s needs and support our country’s push toward a more sustainable future. We’re excited that we can play a role in the evolution of the industry.”

AXIS to be Deployed as NGBS Online Portal

Home Innovation Research Labs and Pivotal Energy Solutions have announced that Pivotal's AXIS software platform will be deployed as the online web portal supporting participation in and administration of the NGBS Green certification program as of September 7, 2021. 

After several years of regional success with AXIS in Arizona and the Pacific Northwest, this will be the first deployment of AXIS supporting a national program.  Pivotal has worked as a technical partner with Home Innovation Research Labs since 2016 to surface NGBS Green certifications within the AXIS database for use in analytics and markets utilizing green and energy efficiency certification data.  Most recently, Home Innovation and Pivotal have been pursuing opportunities to auto-populate NGBS Green certification data within real estate MLS platforms.

Bob Burns, president of Pivotal, said, "This is an exciting next step for Pivotal in working with Home Innovation to develop and support their online portal for the NGBS Green program.  We're thrilled to have this collaboration and to expand the use of AXIS to the national level." 

With the transition of the NGBS Green program to the AXIS platform, NGBS Green Verifiers and clients will be able to register projects, submit verification reports and compliance documentation, and monitor project status in real-time 24/7/365 from any modern internet web browser.  The volume of data available for downstream consumers will also be enhanced with the transition. 

Michelle Foster, Vice President of Sustainability for Home Innovation, added, "We are so excited to be working with Pivotal to streamline our NGBS Green certification process and provide even more value for our clients.  We're confident that over time NGBS Green Verifiers and clients will benefit from using the online portal and that it will enable Home Innovation to move the NGBS program forward in exciting new ways. We are also eager to provide greater transparency for the NGBS Green certification process which will benefit investors, financial institutions, government agencies, and the industry as a whole."

RESNET and Pivotal Energy Solutions Finalize Data Sharing Agreement for MLS Auto-Population

The Residential Energy Services Network (RESNET) and Pivotal Energy Solutions (Pivotal) announced today that a data sharing agreement has been finalized between the two organizations that enables residential certification data from the RESNET Building Registry to be incorporated into Pivotal’s AXIS cloud-based workflow and data management platform. Once aggregated into AXIS, the RESNET data can be used to enable auto-population of real estate listings offered through multiple listing service (MLS) systems throughout the United States.

Bob Burns, president of Pivotal, said, “As the interest in energy efficient housing continues to grow for both environmental and financial reasons, it’s important that the performance of homes is readily available for perspective home buyers. Enabling MLS software platforms to support green fields and making data available are important first steps, but long-term, auto-population of green and energy efficiency data directly into MLS listings is essential to ensure the accuracy and integrity of the data and limit the listing agent’s exposure to liability.” Beyond basic location information, the data included in the RESNET data feed will include the HERS Index Score, date of the rating, and modeled annual energy consumption. If the home has been certified as an ENERGY STAR or DOE Zero Energy Ready home, that information will also be available for auto-population into the MLS listing. RESNET joins a growing list of national and regional organizations sharing green and energy efficiency certification data with Pivotal. Burns added, “We’re excited to be working with RESNET to make their certification data more useful for real estate transactions. With the inclusion of RESNET’s data, AXIS can offer the richest set of certification and performance information in the industry. One day, we hope to reach a point where every home listed for sale will include some type of energy efficiency metric and/or utility cost information to help home buyers make more educated decisions when choosing their next home.”
