Building Energy Management: Projects and Publications
Fraunhofer Center for Sustainable Energy Systems
Selected Energy Management Research Projects
The U.S. Department of Energy has selected a Fraunhofer CSE-led team to carry out a $3.5M, three-year research project to design, develop, and demonstrate an integrated system of solar photovoltaic (PV), energy storage, and facility load management at the utility distribution scale in Massachusetts. Fraunhofer CSE, with National Grid, the Massachusetts Clean Energy Center (MassCEC), and other industry partners, will match the award, contributing $3.5M towards the project.
Non-Intrusive Appliance Load Monitoring
Fraunhofer CSE's patented non-intrusive appliance load monitoring (NIALM) is a way for homeowners and building managers to monitor energy consumption on an appliance-by-appliance basis without having to install dedicated sensors across an entire house or office building.
The majority of U.S. households use either manual or programmable thermostats to regulate their heating. In theory, these thermostats can not only save consumers’ energy, but also leave more money in their pockets thanks to lower heating and electric bills. But are people with an easy-to-operate thermostat more likely to use its energy-saving settings, such as nighttime setbacks?
Providing visual feedback to consumers on their energy use through home energy management (HEM) products has been accepted as an effective way to achieve energy savings. However, HEM products cover a variety of media and device types, all of which may have present different types of information and offer different levels of design. Fraunhofer CSE set out to identify how user preferences for various designs and across different presentation media may affect their likelihood of adoption.
In 2010, Fraunhofer CSE began monitoring several Massachusetts residences that had been designed to be net zero energy homes (NZEHs). NZEHs are an extreme example of what can be achieved in energy-efficient building. However, the technologies and design concepts have direct relevance in a number of different residential applications, and could lead to innovations that become commonplace features in today’s homes.

"A Data-Driven Framework for Comparing Residential Thermostat Energy Performance" [Click to download PDF]
B. Urban, K. Roth
Fraunhofer CSE and Nest Labs have co-developed a new data-driven framework for comparing the energy performance of residential thermostats. This paper identifies the key challenges facing thermostat assessment and proposes a framework that can help overcome those challenges. Savings due to setpoint adjustments (largely behavioral and highly variable) are addressed separately from more automated HVAC-control based savings (largely mechanical and more consistent). We conclude with an illustrative example of a data-driven simulation approach for quantifying setpoint-based performance using anonymous data from selected thermostat users.
