Retrofitting Connectivity for Energy Benefits
This report examines the retrofit solutions on the market today to identify those that could be leveraged to achieve energy benefits in otherwise unconnected residential products.
Harnessing IoT for Energy Benefits
This report examines the landscape of residential IoT products and the functions within those products that can be leveraged to yield energy benefits. These functions include monitoring via on- board sensors and internal or external data feeds, and controls that can reside within or external to the product. We examine the extent to which products possess these functions today, the energy benefits products can achieve with those functions, and the appropriateness of adding additional functions to achieve additional energy benefits.
