Systems and methods for controlling conditioned fluid systems in a built environment

A steam heating control system comprising:

• a server;
• a plurality of electro-mechanical air vents adapted to be placed in fluid communication with a respective plurality of radiators disposed throughout a plurality of rooms of a building;
• a plurality of steam sensors disposed at different radiator sections of each radiator of the plurality of radiators, each plurality of steam sensors configured to sense an amount of steam in each respective radiator of the plurality of radiators;
• a plurality of room temperature sensors adapted to be disposed in a respective one of the plurality of rooms of the building, the plurality of room temperature sensors being configured to measure room temperature in each of the plurality of rooms and to transmit the measured room temperatures to the server;
• a plurality of first controllers, each of which is electrically coupled to a respective one of the plurality of electro-mechanical air vents and the plurality of steam sensors, the plurality of first controllers being configured to transmit the sensed amount of steam to the server and to control the respective plurality of electro-mechanical air vents based on respective first control signals received from the server;
• and
• a second controller electrically coupled to a steam source and configured to modulate the flow rate of steam output from the steam source based on a second control signal received from the server,
• wherein the server is configured to generate the first control signals based on the measured room temperatures and the sensed amount of steam in each radiator of the plurality of radiators to regulate the amount of steam in each radiator of the plurality of radiators, to determine steam requirements of each radiator of the plurality of radiators, and to generate the second control signal based on the determined steam requirements of each radiator of the plurality of radiators to regulate an amount of steam output from the steam source.
