Date: 2021-10-27
San Marcos, California-based energy efficiency software specialist Encycle Corporation reports its Swarm Logic® HVAC energy-saving technology for demand side energy management and energy efficiency optimization has been added to NV Energy's PowerShift offering for its business customers.

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.

DOE Announces $61Mn for Smart, Efficient Buildings, Grid Resilience (Funding)
DOE Building Technologies Office
Date: 2021-10-15
In Washington, the U.S. Department of Energy (DOE) has announced $61 million for 10 pilot projects that will deploy new technology to transform thousands of homes and workplaces into state-of-the-art, energy-efficient buildings. These Connected Communities can interact with the electrical grid to optimize their energy consumption which will substantially decrease their carbon emissions and cut energy costs.

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:

  • Electric Power Research Institute, Inc.(PRI) (New York City, Seattle, San Diego) $5.27 million -- will be used to transform multi-family buildings in affordable housing developments into GEBs that will demonstrate different ways to decarbonize buildings, make them more resilient, and reduce utility bills.

  • IBACOS, Inc. (NC) $6.65 million -- will deploy a coordinated control program to optimize the energy use of a comprehensive mix of distributed energy resources in 1,000 new and existing homes, including single-family and multifamily homes and both owner-occupied and rental properties.

  • Open Market ESCO Limited Liability Company (MA) $6.65 million -- will bring the benefits of efficiency, demand flexibility, renewable generation, and energy storage with more affordable renovations in up to 20 low-to-moderate-income apartment communities.

  • PacifiCorp (UT) $6.24 million -- to establish a program to manage solar photovoltaic, batteries, electric vehicle charging in a diverse community of all-electric buildings and a mass transit transportation center, equipped with the latest market-leading efficient technologies to optimize their collective energy use and provide grid services at scale.

  • Portland General Electric (OR) $6.65 million -- will renovate over 500 buildings in North Portland's historically underserved neighborhoods to reduce their energy burden with numerous energy efficiency measures and connected devices that provide the grid with a range on energy services. (Award amount: $6.65M)

  • Post Road Foundation (ME, NH) $6.65 million -- will investigate the capacity of a novel Transactive Energy Service System to harmonize communications and optimize energy use among the distributed energy resources, local energy markets, and buildings of three rural communities.

  • Slipstream Group Inc. (WI) $5.18 million -- will convert approximately 15 facilities in Madison, Wisconsin into GEBs that connect with nearby electric vehicle charging stations to establish a scalable business model for utilities to install demand flexibility and energy efficiency upgrades across multiple building sizes in public and private sectors.

  • Spokane Edo LLC (WA) $6.65 million -- to unlock demand flexibility up to 2.25 megawatt (MW) using flexible loads in residential and commercial buildings augmented by distributed energy resources within Spokane, Washington's Opportunity Zones of vulnerable populations.

  • SunPower Corporation (CA) $6.65 million -- to build tomorrow's homes today in two communities of all-electric homes in Menifee, California that meet DOE's zero-energy-ready home qualifications and feature solar energy, home energy management systems, and community-scale battery storage.

  • The Ohio State University (OH) $4.2 million -- will investigate the capacity of Ohio State's existing on-campus connected community to provide essential but overlooked ancillary grid services from a diverse range of grid-interactive technologies in a cyber- and data-secure environment.

    The Connected Communities funding opportunity is led by DOE's Building Technologies Office. (Source: US DOE Building Technologies Office, PR, 13 Oct., 2021) Contact: US DOE Building Technologies Office, www.energy.gov/eere/buildings/building-technologies-office

  • DOE Releases Spawn of EnergyPlus Building Energy, Controls Modeling Software (Ind. Report)
    US DOE EERE
    Date: 2021-07-28
    The U.S. Department of Energy's Building Technologies Office, the Lawrence Berkeley National Laboratory and the National Renewable Energy Laboratory, in collaboration with Modelon and Objexx Engineering, have released the initial version of the Spawn of EnergyPlus (Spawn)

    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.

    PNNL Releases New Bldg Energy Efficiency Software (Ind. Report)
    PNNL
    Date: 2021-01-20
    The Pacific Northwest National Laboratory (PNNL) is touting its Facility Energy Decision System (FEDS), an easy-to-use software tool that performs energy efficiency assessments by analyzing existing building energy use and identifying cost-effective savings opportunities.

    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.
