Abstract: A flow control device for controlling an air curtain formed across a display area of a refrigerated display case, the flow control device comprising: a stabilizing beam comprising an elongate outer cover and a carrier; wherein the outer cover forms a continuous boundary which defines a cavity extending along the length of the outer cover; wherein the carrier is slidably received within the cavity along the length of the outer cover; wherein the carrier is provided with a light source and wherein at least a portion of the outer cover is transparent or translucent such that light emitted by the light source is emitted from the outer cover to provide illumination.

Abstract: An active airflow inhibiting apparatus for an entranceway comprises: a structure positioned adjacent an entranceway of a building and defines a passage therethrough for accessing the entranceway. The structure defines at least one plenum chamber and first and second outlet slots fluidically coupled to the plenum chamber. A fan fluidically connected to the plenum chamber supplies an airflow to the plenum chamber in order to selectively form a jet of air from the first outlet slot in a first mode of operation and from the second outlet slot in a second mode of operation The first and second outlet slots are configured so that the respective jets of air are each directed towards a centre of the structure, with the jet of air from the first outlet slot being directed away from the entranceway and the jet of air from the second outlet slot being directed towards the entranceway.

Abstract: Building management systems and methods are described herein which augment predicted weather data with an external model of a built environment to calculate wind infiltration into a specific building or wind conditions at a building site. The wind infiltration can be used to predict the performance characteristic of at least one energy consuming component installed in the building, whereas the wind conditions can be used to determine whether the calculated wind conditions exceed a safety threshold.

Abstract: A riser plate for a shelf of a refrigerated display case and kits of parts allows an angle between an outer guiding surface of a riser plate and an inner retaining surface to be adjusted.
