We all know the feeling of walking into an air-conditioned office building on a hot summer day. It's 94℉ outside. It's 64℉ inside. Suddenly, you need a knit sweater just to sit at your desk. I know someone who used to bring a space heater to work - in August.

　　Aside from being uncomfortable, this is horrifically inefficient. The low hum of the air conditioner is the sound of coal being burned and money being spent to make you miserable at work. BuildingIQ is trying to change that. Their secret weapon? Machine learning.

　　The company has developed cloud-based software that gathers information about a building and uses it to build a thermal model(热模型). That model can predict how much or how little energy is needed to keep the people inside comfortable by analyzing factors like indoor temperature and pressure, electricity consumption, the weather forecast, the price of electricity, and therefore tailors heating and air conditioning for maximum energy efficiency.

　　Thanks to a recent cooperation, BuildingIQ will soon take human preferences into account. Changes to heating and air conditioning are always influenced by the limits of human comfort, and those limits vary from person to person. This data will be added into the thermal model. Imagine a retirement home where the occupants are always too cold. If the system knows this, it will reduce the air conditioning in the summer to keep grandma and grandpa nice and warm.

　　How well does it work? BuildingIQ says it regularly saves between 10 and 25 percent on heating and air conditioning, the two items that make up 50 or 60 percent of a building's total energy use. The software will help cut energy bills and improve comfort all while reducing our reliance on fossil fuels. It won't be long before you can leave your space heater at home.
