A roof ventilation system operable based on environmental parameters is disclosed. The system includes a vent, a fan, a solar panel, a battery and a controller. The vent is positioned within a field of a roof, and includes a first opening configured to allow airflow between regions above and below the roof. The fan is positioned to generate an air flow through the vent. The solar panel is positioned on the roof in a location such that the solar panel receives solar radiation. The battery is electrically connected to the solar panel. The controller is in communication with the fan, and is configured to drive the fan based on at least one environmental parameter.

1. A roof ventilation system for a sloped roof of a building, the roof having a ridge and an eave, the system comprising: a first roofing layer;a second roofing layer constructed from a plurality of similar roofing tile elements disposed over the first roofing layer to form an air gap that extends between the first and second roofing layers substantially from the ridge to the eave;a first plurality of at least three vents arranged generally linearly and positioned within the roof proximate the ridge, each vent of the first plurality of vents comprising: a primary vent member positioned within the first roofing layer and comprising an opening that permits airflow between the air gap above the first roofing layer and an attic region below the first roofing layer,a fan configured to generate an exhaust air flow through the opening from the attic region below the first roofing layer to a region above the second roofing layer, anda secondary vent member positioned within the second roofing layer, and in air flow communication with the primary vent member through the air gap, the secondary vent member allowing airflow between the air gap and the region above the second roofing layer;a second plurality of at least three vents arranged generally linearly and positioned within the roof proximate the eave, each vent of the second plurality of vents comprising: a primary vent member positioned within the first roofing layer and comprising an opening that permits airflow between the air gap above the first roofing layer and the attic region below the first roofing layer,a fan configured to generate an inward air flow through the opening from the region above the second roofing layer to the attic region below the first roofing layer, anda secondary vent member positioned within the second roofing layer, and in air flow communication with the primary vent member through the air gap, the secondary vent member allowing airflow between the air gap and the region above the second roofing layer; anda controller in communication with the fans of the first and/or second plurality of vents, the controller being configured to drive the fans based on at least two types of environmental parameter, so that the fans of the first plurality of vents produce said exhaust airflow and so that the fans of the second plurality of vents produce said inward airflow. 2. The system of claim 1, wherein at least some of the vents further comprise solar panels positioned to receive solar radiation for powering at least some of the fans. 3. The system of claim 2, further comprising a battery electrically connected to the solar panels of the first plurality of vents. 4. A ventilated roof of a building, the roof having a ridge and an eave, comprising: a first roofing layer;a second roofing layer constructed from a plurality of similar roofing tile elements disposed over the first roofing layer to form an air gap between the first and second roofing layers;a first plurality of at least three vents arranged generally linearly and positioned within the roof proximate the ridge, wherein each vent of the first plurality of vents includes a fan positioned to generate an air flow through the vent;a second plurality of at least three vents arranged generally linearly and positioned within the roof proximate the eave, wherein each vent of the first and second pluralities of vents comprises: a primary vent member positioned within the first roofing layer, the primary vent member comprising an opening that permits airflow between an attic and the air gap; anda secondary vent member positioned within the second roofing layer, and in air flow communication with the primary vent member through the air gap, the secondary vent member allowing airflow between the air gap and a region above the roof, wherein said second roofing layer includes air flow passages between the tile elements;a solar panel positioned in a location such that the solar panel receives solar radiation;a battery electrically connected to the solar panel so that the solar panel charges the battery from solar radiation; anda controller adapted to communicate with one or more of the fans, the controller being configured to: receive a toxicity value and determine whether the toxicity value exceeds a toxicity threshold;receive a temperature value and determine whether the temperature value exceeds a temperature threshold;receive a humidity value and determine whether the humidity value exceeds a humidity threshold; anddrive the one or more fans in response to a determination that any of the received values exceeds its corresponding threshold, the controller being configured to be powered by the battery. 5. The roof of claim 4, further comprising battens interposed between the first and second roofing layers, wherein the battens form the air gap. 6. The roof of claim 4, wherein the solar panel is mounted on the secondary vent member. 7. The roof of claim 4, further comprising a user interface that permits an inhabitant of the building to adjust the thresholds. 8. The roof of claim 7, wherein the user interface is configured to allow the inhabitant to control the fans. 9. The system of claim 1, wherein the controller is configured to receive and process values of two or more environmental parameters from the group consisting of a temperature parameter, a humidity parameter, a toxicity parameter, a moisture parameter, an air flow parameter, and an ambient light level parameter, the controller configured to drive the fans in response to a determination that any one of the received parameter values is not within a predetermined range associated with the environmental parameter having the received parameter value, the system further comprising a user interface permitting an inhabitant of the building to adjust at least some of the ranges associated with the two or more environmental parameters. 10. The system of claim 1, wherein roofing tile elements of the second roofing layer are disposed with downslope edges overlying upslope edges of adjacent roofing tile elements, the downslope edges spaced from the upslope edges of the adjacent roofing tile elements a sufficient distance to create air flow passages between the downslope and upslope edges.
