RESIDENTIAL INTEGRATED VENTILATION ENERGY CONTROLLER
First Claim
1. A system for controlling the ventilation of a house, said system including:
- a) a whole-house fanb) one or more other home supply or exhaust fansc) a controller for regulating the on-off time of the whole-house fan, said controller including a central processing unit, a bios, a clock, and memory, said memory including programmable software for both calculating the relative exposure and relative dose within the building, and instructions based on the calculated relative exposure and relative dose to either turn the whole-house fan on or off; and
,d) communication links with the one or more other home exhaust or supply fans, such that a signal is sent from each of the one or more other home exhaust or supply fans to the controller, indicating the operating status of the fan, such as whether or not it is on or off, or operating an some intermediate speed, and a set of instructions within the controller which either turns the whole-house fan on or off, or set it to some intermediate speed, in response to the signals from the other home exhaust or supply fans.

Abstract
A residential controller is described which is used to manage the mechanical ventilation systems of a home, installed to meet whole-house ventilation requirements, at the same time reducing energy costs. This is achieved in part by shifting the ventilation load of the whole-house system to off peak hours and by taking into account exogenous mechanical ventilation induced by other systems. The controller is linked by wire or wirelessly to other house ventilation systems using any one of a number of communication protocols, sensing the on-off status of such exogenous systems. An operational algorithm preloaded and/or modified at the point of use is used to control the on-off status or fan speed of a whole-house ventilation fan which forms a part of the home ventilation system, the operating status of the whole-house fan in part responsive to the status of other home ventilation systems, and in part based on time of day.

8. A system for controlling ventilation within a structure including:
-
a) a main whole-house ventilation control fan, including an on-off switch or variable fan speed controller, said fan located within said structure; b) one or more supply or exhaust fans located within said structure, each of said fans having an on-off switch, or variable fan speed controller; c) a central controller in communication with the said switches or speed controller of said main whole-house ventilation fan and said one or more supply or exhaust fans; and
,d) a software program associated with said central controller, which software program includes a set of electronic instructions which provides among other things for the monitoring of the status of the one or more supply or exhaust fan switches or speed controllers, such that if said one or more of said supply or exhaust fans are operating, an electronic instruction is sent to the on-off switch or variable fan speed controller of the main whole-house ventilation control fan to turn it off or to some reduced speed. - View Dependent Claims (9, 10, 11, 12, 13)
