As a builder or a building owner, you can best optimize the energy savings by using energy management systems. They control and monitor energy consuming devices that include cooling and heating equipment, lighting, fans, dampers, switches and pumps. They can also be used to control the refrigeration equipment and ventilation. Control4 Energy Management System Longmont will provide sensors that will measure temperature, pressure and light levels that are used to initiate responses by the system. The controllers will compare the signals received from the sensor to a specified point and set out a signal to a control device for action. The control device receives the signals from the heating, ventilation and air conditioning also.
