Encycle's Swarm Logic® software will be integrated into commercial connected thermostats offered by NV Energy under its PowerShift portfolio for business customers with 6 or more thermostats. As part of the offering, customers receive a free thermostat that is compatible with Swarm Logic technology to help lower their heating and cooling costs.
Deployed as an Energy-as-a-Service (EaaS) solution, Swarm Logic typically saves customers 10 to 30 pct on HVAC-related energy consumption, spend, and emissions, according to the release.

Connected communities of grid-interactive efficient buildings (GEBs) use smart controls, sensors, and analytics to communicate with the electrical grid, reducing the amount of energy they require during periods of peak demand. This capability is used to optimize buildings and distributed energy resources to maintain the comfort of the building occupants, lowers utility bills, and reduces grid system costs.
A recent DOE study estimated that by 2030, GEBs could save up to $18 billion per year in power system costs and cut 80 million tpy of carbon emissions -- more than the annual emissions of 50 medium-sized coal plants or 17 million cars. DOE's first two connected communities in Alabama and Georgia have already demonstrated this potential by using approximately 42-44 pct less energy than today's average all-electric home.
The 10 pilot projects include:
The Connected Communities funding opportunity is led by DOE's Building Technologies Office.

Spawn is not a replacement for EnergyPlus, at least not in the foreseeable future. Although it does perform whole-building energy simulation, it targets new use cases in advanced controls, district systems, and grid integration.
Spawn supports these new use cases by making fundamental use of coupled simulation via the Functional Mockup Interface standard. Spawn reuses the weather, envelope, lighting, and loads models from EnergyPlus and packages them as a single model. However, it replaces EnergyPlus' traditional, imperative, implicit, load-based HVAC and controls models with explicit declarative state-based models from the Modelica Buildings Library which are translated and automatically linked with the EnergyPlus model. By combining models in different configurations, Spawn is able to simulate either a single building or a collection of buildings linked by shared thermal, electrical, and control systems.
Spawn also fundamentally leverages the Modelica, a standard for equation-based modeling. The use of Modelica to model HVAC and control introduces capabilities that are not found in traditional energy simulation engines such as EnergyPlus. The most significant of these is the ability to simulate physically realistic control sequences using the same specification that is used in controller implementations. The ability to use a single control specification for both energy simulation and implementation aims to bridge these traditionally separate domains and promote the use of high-performance control sequences. Modelica also enables modeling of novel HVAC and district system components and configurations. Spawn HVAC and control models have been developed as part of a multi-year international effort led by IEA EBC Annex 60 and IBPSA-World Project 1 to develop Modelica models for building and community systems.

A key attribute of FEDS 8.0 is the ability to initiate assessments with a limited detail of characteristics. FEDS fills in unknown details based on the parameters specified with a sophisticated internal inference generator whose results can be reviewed and updated as appropriate.
The highly scalable tool simulates building systems, including building shell, lighting, HVAC, and water heating technologies and calculates loads and energy use to analyze the cost and performance impact of thousands of potential efficiency measures.
Development of FEDS was supported by the U.S. DOE Federal Energy Management Program in coordination with other government agencies.
