This project seeks to support wider availability and use of building energy information by focusing on two activities: energy monitoring, and benchmarking.
There are many commercially available EIS solutions and the technical capability and commercial availability of these solutions continues to increase. However one of the barriers to wider market penetration of EIS is the relatively high transaction cost of deploying EIS, including the skill and time required to configure, install and use EIS. This is compounded by the wide diversity in how buildings are wired and metered, and the level of awareness of the value of EIS.
The first focus of this CBERD task is on developing packaged and scalable technical solutions for Energy Information Systems (EIS) that reduce the cost, time and skill required to install and operate EIS, thereby enabling wider deployment of EIS. These solutions will build on and can be integrated into existing EIS and metering products applicable to the U.S. and Indian markets.
Building energy benchmarking development and application in the US is far more mature than in India, which only recently rolled out its first benchmarking tools for selected building types. The nascent state of benchmarking in India affords an opportunity to develop methods and tools that build on US experience and lessons learned. The second focus of this CBERD task is on advancing state of the art of energy benchmarking by developing methods and models based on empirical data from Indian buildings. The models will build on applicable concepts and models from U.S. benchmarking programs, and inform the development and deployment of benchmarking programs in India.
The key contribution of this work will be to distill state-of-the-art energy analysis into packaged EIS solutions that can be deployed broadly at scale in both countries US and India, and at significantly lower transaction costs. This is a new, tiered EIS configuration that accommodates building heterogeneity for target building typologies selected through a market segmentation study, namely offices, business hotels, and hospitals. Another impact is the development of a new graduated benchmarking method for incorporating uncertainty information in building energy benchmarking scores that can be adopted by national benchmarking programs.
