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.

A hydronic assembly connectable to a building's water and air distribution systems to manage and deliver conditioned air to a unit of the building includes an enclosure including a hydronic coil configured to heat or cool air within the enclosure, a valve control system coupled to the hydronic coil for regulating the flow of water through the hydronic coil, and an air supply booster for circulating air within the enclosure and delivering the same to the unit. The enclosure includes a return air inlet for recirculating air to the enclosure, a supply air outlet for supplying air to the unit, and a return air separation baffle separating the return air inlet air stream from the supply air outlet air stream. The enclosure is removably attachable to the building's air distribution system. The hydronic coil includes piping that is removably attachable to the building's water distribution system.

Described herein is a free cooling and heating system for a multi-storey building. The system includes a plurality of temperature sensors configured to measure temperatures on different floors, an air handling unit (AHU) integrated with an HVAC unit, including at least one blower unit configured to transfer air between the different floors. The system further includes at least one motorized damper positioned within a Wye branch, with the Wye branch configured to connect the HVAC unit with the AHU to transfer conditioned air to the required floor, and a computing device operatively connected to the plurality of temperature sensors, the air handling unit, and the at least one motorized damper of the Wye branch.

A safety system implemented within a structure includes a source of breathable air, and a fixed piping system to supply the breathable air from the source to each level of a number of levels of the structure. The fixed piping system is implemented in a loop architecture including a first portion proximate the each level of the number of levels and a second portion farther away therefrom. In accordance with the loop architecture, the first portion and the second portion are implemented as a continuous loop with respect to the source of the breathable air such that, even during a compromise of a first sub-portion of the first portion relevant to one or more level(s) of the number of levels proximate thereto, unaffected by the compromise, the breathable air continues to be supplied to a second sub-portion of the first portion by way of the second portion.
