There are three broad categories of data that will be needed to make buildings more energy efficient, healthy and comfortable. First, utility consumption data will be collected at a per unit and building basis from devices like smart meters, home and office accessories and sensors (e.g. Nest smart thermostats). Appliance and plug-load sensors can also aid in collecting device usage for items like your refrigerator, washing machine, and electric vehicle (EV) charging stations. Second, personal demographic data will be collected to segment usage and will be captured through building records and personal reporting (e.g. surveys). Last, environmental data, such as temperature and rainfall data will be collected to provide proactive mechanisms to reduce energy consumption.
