A building system for a building including one or more storage devices storing instructions thereon that, when executed by one or more processors, cause the one or more processors to operate one or more pieces of building equipment associated with a building space based on a first operating mode. The instructions cause the one or more processors to receive an indication to update operation of the building space based on an emergency situation and responsive to receiving the indication to update operation of the building space based on the emergency situation, operate the one or more pieces of building equipment based on a second operating mode, wherein the second operating mode defines one or more second parameters for the one or more pieces of building equipment and is adapted to reconfigure the operation of the building space to address or mitigate the emergency situation.

A method of monitors a climate quality within a building having an elevator running between floors of an elevator hoistway. The elevator car of the elevator includes at least an air-quality sensor. The method is characterized in that a fan of the elevator car is running when the door(s) of the car is/are opening at a floor station to suck air from the building's floor level into the elevator car to the vicinity of the air-quality sensor and sensing the air-quality by the sensor preceding to generating data of the air-quality.

An HVAC system for a multi-unit building having a riser stack in flow communication with a single unit HVAC system. The single unit HVAC system has a first heat exchanger thermally connected to the riser stack, a second heat exchanger thermally connected to a fluid distribution system within the unit, and a closed loop fluid flow path extending between the first and second heat exchangers. The first heat exchanger exchanges heat between a riser stack fluid in the riser stack and the closed loop fluid in the closed loop fluid flow path and the second heat exchanger exchanges heat between the closed loop fluid and a distribution fluid of the fluid distribution system.

A structure for a multi-story building comprises a first passageway constructed internally within a building being configured with a mount for a ducted condenser unit (DCU) of a split type, unitary air conditioning system to achieve a desired level of condenser based heat dissipation and with a plurality of penetrations to accommodate a conduit through which refrigerant circulates between inside and outside units of the air conditioning system; and a second passageway constructed internally within the building for receiving air discharged from the DCU the second passageway terminating at an opening of the building through which the discharged air is exhausted to the atmosphere. The passageways have walls that are essentially closed, with the exception of the wall that is formed with an opening through which the discharged air flows. One or both of the first and second passageways upwardly extends across at least two stories of the building.

Determining building weather profile parameters, and correcting an estimated altitude of a receiver using the building weather profile parameters. Systems and methods for estimating an altitude of a receiver using building weather profile parameters may identify one or more weather profile parameters for a building, determine an initial estimate of a receiver's altitude at a floor inside the building, and use the initial estimate and the identified weather profile parameters to determine a corrected estimate of the receiver's altitude at the floor.

The air flow of an HVAC system for a multi-story building B is controlled by optimizing the pressure setpoint at the return air plenum PL-1 used for removing or recirculate air from the building, by measuring a pressure differential between the building B air and atmosphere A air at a sensor location P-2, computing a desired pressure differential between the building B air and atmosphere A air, based upon a computed stack effect pressure that is expected to develop at the sensor location on the building for the current inside and outside air temperature in the absence of mechanical action, and controlling the return air fan and damper D-1 to pressurize the air in at the sensor location to produce the desired pressure differential between the building B air and atmosphere A air at the sensor P-2 location.

A single unit HVAC system for a unit in a multi-unit building comprises a first heat exchanger thermally connected to a riser stack, a plurality of fan coils, each fan coil comprising a unit heat exchanger and a motor and fan assembly wherein, in operation, the motor and fan assembly delivers air to a location in the unit, and a closed loop fluid flow path extending between the first heat exchanger and the plurality of unit heat exchangers. In operation, the first heat exchanger exchanges heat between the riser stack fluid and the closed loop fluid, each unit heat exchanger exchanges heat between the closed loop fluid and air that is delivered to a different room in the unit.

An access control system receives a trigger command for controlling a ventilation system; determines that the trigger command includes a lock trigger to hold an entrance door in a closed position; and induces a locking differential air pressure between opposite sides of the entrance door in response to the lock trigger, where the locking differential air pressure is sufficient to bias the entrance door to contact or to increase contact with a door frame in the closed position. The access control system may also determine that the trigger command includes an open assist trigger to ease an opening of the entrance door; and may induce an opening differential air pressure between the opposite sides of the entrance door in response to the open assist trigger, where the opening differential air pressure is sufficient to bias the entrance door to reduce contact with the door frame in the closed position.

A facade panel conditioning system for installation on a new or existing building is disclosed. The system includes modular panels, a structural anchor, hydronic piping, and ductwork. The panels attach to each other around the exterior of the building forming an insulated shell. The anchor attaches the panels to the building structure forming an air cavity between each individual panel and the exterior. The hydronic piping transfers heat to the air cavity and individual units of the building. The ductwork delivers ventilated air and exhaust air to the air cavity and individual units. The hydronic piping of a panel connects to the hydronic piping of an adjacent panel forming a hydronic piping system that distributes heat or cool throughout the shell. The air duct of a panel connects to the air duct of an adjacent panel forming an air duct ventilation system that distributes air throughout the shell.

A building system for a building including one or more storage devices storing instructions thereon that, when executed by one or more processors, cause the one or more processors to operate one or more pieces of building equipment associated with a building space based on a first operating mode. The instructions cause the one or more processors to receive an indication to update operation of the building space based on an emergency situation and responsive to receiving the indication to update operation of the building space based on the emergency situation, operate the one or more pieces of building equipment based on a second operating mode, wherein the second operating mode defines one or more second parameters for the one or more pieces of building equipment and is adapted to reconfigure the operation of the building space to address or mitigate the emergency situation.
