We are leading the way to a resilient and sustainable future by helping architects, developers and building owners create high-performance, climate-positive buildings. From commercial and residential buildings, hospitality and entertainment, sports, and recreation, to supertall buildings, we help ensure projects fit within their climate.

Please note that all heights shown in italics/red are estimated heights. These have been calculated based on known floor counts for the building, then extrapolated through analyzing typically hundreds of buildings of the same function on this database that do have confirmed heights. The user should be aware that non-standard building features, such as significant spires or raised entrances / podiums, may affect the accuracy of these estimations.
