Walmart - Site Characterization

The Site Characterization Report, prepared by the Center for Sustainable Energy, outlines existing conditions at the test-site, including equipment schedules, sub-system details, and an equipment inventory. Additionally, the report includes an initial energy profile and benchmarking results for the test site.

Walmart - Baselining, Design and Modeling

The Baseline Period Measurement and Verification Plan, prepared by the Center for Sustainable Energy, defines the baseline energy and water performance of the site including which building and system components will be monitored, the monitoring interval and period, the equipment necessary to obtain the required data, and other details related to equipment installation planning.

The project team will design and install a holistic suite of precommercial energy efficiency (EE) technologies for the Covina Walmart building. P2S will design the energy efficiency technology package and prepare a basis of design, design documents and construction documents.

To inform the energy efficiency technology package selected, NREL used the Department of Energy’s OpenStudio Modeling Software to complete baseline and calibrated energy models. They also performed an optimization study whereby the baseline energy model is run with various energy efficiency technology packages.

Each energy efficiency package will include different combinations of precommercial technologies to determine the best energy efficiency package, as well as the best scheduling of technologies when interacting with one another. Additionally, the final calibrated energy model will be utilized for comparison during a set measurement and verification period after the installation of all selected technologies.

Walmart - Installation

TRC will provide construction project management support for various aspects and phases of the project. TRC’s primary role will be technology implementation of the selected technologies identified in design. They will work with all technology project partners and the Walmart demonstration site to ensure that the EE technologies are installed properly and commissioned according to the design intent and that construction activities are coordinated and executed in a manner that minimizes site operation disturbances.

Walmart - Measurement and Verification

The project team will conduct measurement and verification activities to identify whether the installed precommercial energy efficiency technology package successfully delivered the planned level of electricity savings. Measurement & Verification data will be collected and compared to performance targets, used to support model calibration and to ascertain the California-wide potential of the demonstrated technologies.

Walmart - Technology Knowledge Transfer Activities

To maximize the impact of the project, the project team will develop and execute a plan to share the knowledge gained and lessons learned from this project with the public and key decision-makers. Our approach will include outreach to industry stakeholders, store shoppers, state and local policymakers and community leaders.

The team will host a series of public webinars as well as develop and disseminate outreach and educational materials about the building technologies tested, energy features and integrated demand-side management framework. Additionally, the project team will use results from this project to help educate California government officials by way of participation in California Public Utility Commission (CPUC) regulatory proceedings when appropriate.
