The presentations, news, research summaries, reports, and technology overviews are collected here by focus area and represent the body of work developed by the CBEI partners during the 5-year project period. For additional information on market challenges, approach, and impacts, see each focus area overview.
The project has developed a business plan and revenue model for maintaining and sustaining the Certificate program after last budget period.
Medium office buildings in the Greater Philadelphia offer high potential to reduce building energy consumption. This study assesses the impact of a wide set of ECMs in combinations as retrofit packages, and which combinations offer the most energy conservation for a given investment.
An automated Building Retuning report generator with Asset Score Preview reporting capability is complete. It has been used by Penn State students to generate reports for the “Leadership in Building Energy Efficiency” course as well as demonstrated to BOMA and APPA BRT training participants. It has been incorporated into the BRT course content.
CBEI performed a major retrofit of their headquarters. This report provides early lessons learned from the integrated design process.
Over two years, this project developed an effective energy efficiency training course for commercial brokers that satisfies their continuing education requirements. The team then extended the reach of the program beyond Philadelphia and have established a long term path for the program with the Certified Commercial Investment Member Institute.
This project worked with developers of DOE tools such as the Asset Score Tool and BuildingSync and developed outreach tools and engagements to accelerate and enhance utilization of these tools.
Policy implementers are interested in identifying the most effective ways to promote the use of benchmarking data in order to (a) add relevance to energy data in real estate transactions, and (b) increase investments into energy efficient building retrofits. This report provides feedback from representatives of more than 21 organizations operating in the Philadelphia, New York City, and regional or national markets on the benefits of public energy benchmarking data.
The goal of this project was to demonstrate and evaluate a practical business case for implementation of the RTU Coordinator across multiple locations. This report provides a summary of the PnP algorithm, a description of the savings estimates for previous PnP evaluations, a description of site selection processes and savings results for the BoA sites, and a description of the final demonstration sites, implementations and preliminary results.
The project team demonstrated commitment from four training organizations to integrate Asset Score Tool training into their education and training programs.
This report on Residential & Commercial Buildings is one of five research reports for the Alliance Commission on National Energy Efficiency Policy, which assesses the current state of efficiency within the economy and provides a review of the best local, state, and national practices.
The paper provides a survey of recent literature that highlights the influence of factors, such as social, cultural, environmental and regulatory, on electricity consumption behavior.
Recent developments in building controls and diagnostics techniques promise to improve occupant comfort while minimizing energy consumption. A new generation of Human Machine Interfaces (HMI) for building automation systems is needed to allow facility managers to leverage the potential of advanced controls and diagnostics. In this paper we will describe a design process and the end product, a novel HMI prototype and the system that supports it. The system is an integration of advanced algorithms, an underlying software architecture, building equipment, and the human operators that use it.
The paper provides a review of literature on the building occupant behavioral characteristics.
The airflow in enclosed environments is a wall bounded flow, consisting of circulation, flow separation, and thermal plumes in transitional to fully developed turbulence. This study developed a new Detached Eddy Simulation model for indoor airflow using a semi-v2f model, and this model correctly predicted near-wall flows. This study applied the new DES model to a mixed-ventilation and a strong buoyancy-driven flow in rooms.
Fluid Dynamics (FFD) could be potentially used for real-time indoor airflow simulations. This study developed two-dimensional Fast Fluid Dynamics (2D FFD) into three-dimensional Fast Fluid Dynamics (3D FFD) and improved the data structure for handling computational domain with more complex geometry.
