Accuenergy, a Canada-based manufacturer of power and energy measurement equipment, has launched AcuPanel EASI to help US building owners comply with energy-code reporting requirements.
The offering combines multi-circuit metering equipment with code reviews, equipment selection, documentation, programming and commissioning services. It is intended for projects that must meet metering requirements set out in ASHRAE 90.1, the International Energy Conservation Code (IECC) and California’s Title 24 energy standards.
Readings from individual circuits are grouped by how the building uses electricity. Categories can include heating, ventilation and air conditioning (HVAC), interior lighting and plug loads, which cover equipment connected to electrical outlets. Property and facilities teams can then compare consumption across these categories.
Energy data organised by building use
AcuPanel EASI collects electricity consumption data from metering panels and forwards it to AcuHMI, the central touchscreen and data gateway. It records consumption in kilowatt-hours (kWh).
AcuHMI stores readings from the connected meters for local access. Data is collected at 15-minute intervals and categorised as required for energy-code reporting.
Users can obtain reports for individual categories covering periods such as the previous hour, week or month. The information is available via the touchscreen or a browser-based interface.
AcuHMI includes 32 GB of onboard storage, which Accuenergy says can retain approximately three years of measurements. The records remain available at the building rather than being stored solely in the cloud.
Kira Schmidt, business unit director at Accuenergy, said that separating HVAC, lighting and plug-load consumption could help owners identify areas of concern, assess the results of improvements and make decisions about operating costs.
Services cover planning and commissioning
Energy codes may require recording electricity consumption separately for different building systems. Each project must identify which circuits require monitoring and how to categorise their readings.
Accuenergy’s services cover the planning, configuration and commissioning of installations. The company can review project requirements, prepare equipment take-offs and bills of materials, and produce technical submittals.
An equipment take-off identifies the components and quantities required for a project. The bill of materials lists the required metres, current transformers, cables and data loggers. Current transformers are sensors that measure electrical current without being connected directly to the main current path.
Technical submittals include product specifications and supporting information, which project engineers review before approving equipment for installation.
During commissioning, the installed equipment is checked and configured to confirm that it records, groups and reports the required data accurately.
Three panel configurations available
AcuPanel EASI is available in configurations with three, 24, or 48 current inputs. The three-input version uses an Acuvim CL multifunction meter and is intended for feeder- and equipment-level monitoring.
The 24-input model contains one AcuRev 4100 multi-channel submeter, while the 48-input version contains two. Both can monitor single-phase, two-phase and three-phase circuits. The panels connect to a central data logger via Ethernet or RS485, a communications standard widely used by meters and building equipment.
The AcuRev 4100 preceded AcuPanel EASI. Accuenergy launched the meter in February 2026, supporting up to 24 single-phase circuits or eight three-phase circuits. It uses Modbus and BACnet, communication protocols that enable meters, building controls and management systems to exchange data.
The meter complies with ANSI C12.20 Class 0.2 and IEC 62053-22 Class 0.2S, standards for electricity-meter accuracy.
AcuHMI was introduced separately in November 2025. The seven-inch touchscreen combines a data logger with a gateway that can collect information from devices using different communication protocols.
Designed around US energy codes
ASHRAE 90.1 sets minimum energy-efficiency requirements for most buildings, except low-rise residential properties. ASHRAE develops the standard through a process approved by the American National Standards Institute.
The International Code Council developed the IECC as a model code. States and local authorities can adopt it as the basis for their building energy requirements. The code and edition in force can therefore vary by location.
California maintains its Building Energy Efficiency Standards in Title 24, Part 6, of the California Code of Regulations.
AcuPanel EASI is intended for projects that apply the metering provisions of these standards and codes. Its browser interface presents readings by consumption category, so users do not have to retrieve data from each meter separately.
Accuenergy also plans to add artificial intelligence capabilities to the product. It has not disclosed what those capabilities will cover or when they will become available.
