About Us

Demand Logic is an award winning company on a mission to make big buildings work better for people and the planet.

Our cloud-based platform streams large volumes of real time data from building controls systems (e.g. heating, ventilation and air conditioning) and sensors monitoring the performance of every aspect of a building's plant and environment.

We use this data along with pioneering modelling, analytics and visualisations to focus users on costly performance issues that otherwise go unnoticed for years. The resulting insights help our customers save serious amounts of energy, improve indoor environments and reduce costs.
