LBNL maintains the world's largest database of actual commissioning costs and benefits, with projects encompassing approximately 100 million square feet of non-residential building floor area. The assessments begin with compilation of case-study data on project expenditures, energy savings, the patterns of deficiencies and corrective measures, and non-energy benefits. The resulting analyses include cost-effectiveness, savings persistence, and greenhouse-gas abatement.
The purpose of this project is to develop: A) a technical performance specification and adoption plan for controllable fluorescent ballasts and B) techniques to automatically diagnose the operations of scheduled sweep controls in commercial buildings. More about Lighting.
LBNL is developing an interface and new features for PG&E's Universal Translator (UT). The UT is a publicly-available tool for managing, analyzing, and visualizing field performance data, such as building plug and lighting loads, equipment run times, economizer operation, and set-point control. The tool has the potential to be useful in other applications, such as Fault Detection Diagnostics (FDD) and Measurement and Verification (M&V).
The DOE Commercial Building Partnership Program (CBP) provides technical assistance to retrofit and new construction projects, ranging from a minimum of 30% energy savings for retrofit through to net zero retrofits, and a minimum of 50% energy savings over ASHRAE 90.1-2007 to net zero new construction. The projected energy savings are validated through measurement and verification, and energy-saving measures are leveraged to provide solutions for the commercial building market sector.
The DOE Commercial Building Energy Alliances (CBEA) work with industry partners across the retail, commercial real estate, hospitals, and higher education sectors to identify barriers to the implementation of energy efficiency, and to deploy energy efficiency technologies and solutions as developed.
The FLEXLAB will provide a flexible infrastructure to allow for testing and validation of integrated low energy systems, including lighting, facades, shading, HVAC, and plug loads. The facility includes testbeds with interchangeable exterior and interior infrastructure to allow for a wide variety of systems testing. The facility also includes interior testbeds such as the Occupied Plug Loads and Lighting testbed, a Controls Hardware testbed and a Virtual Design testbed.
The Department of Energy’s Buildings Performance Database (BPD) is a decision-support platform, comprised of a database and data analysis tools, that enables engineering and financial practitioners to evaluate energy efficiency products and services in commercial and residential buildings. The database includes measured energy use and building characteristics for tens of thousands of buildings. LBNL leads the development of the taxonomy for the BPD.
EnergyIQ is an action-oriented benchmarking tool for non-residential buildings that allows users to benchmark their buildings using energy, cost, and carbon metrics at the whole-building and system level. Buildings can be benchmarked against the California End Use Survey (CEUS) or the national Commercial Building Energy Consumption Survey (CBECS), and the tool provides users a list of potential efficiency actions based on the benchmarking data.
Commercial mortgage contracts currently do not fully account for the risks inherent in the level and volatility of energy use in commercial buildings. This project analyzed energy risks in commercial mortgages and their impacts on commercial mortgage valuation. The project also developed guidance on risk management approaches.
The Energy Information System (EIS) Handbook was developed to help commercial building software developers, energy managers, and control companies to implement strategies for commercial building energy analysis and to monitor performance.
The Building Controls Virtual Test Bed (BCVTB) is a software environment that allows expert users to couple different simulation programs for co-simulation, and to couple simulation programs with actual hardware.
