Facade design: The benefits of early-stage energy modelling

Indeed, as a project matures, it becomes increasingly difficult, as well as costly, to make effective changes to the performance. In response to this need, KPMB LAB, the research and innovation group at KPMB Architects, has developed a basic energy modelling tool for internal use on projects. This article discusses how the tool works, how it relates to more comprehensive energy modelling software, and how it can be useful to an architect during concept and schematic design phases.

Essential structural considerations in roof design

Design professionals often work in isolation, with each discipline (architectural, structural, mechanical, and electrical) doing their own thing and only getting together after they have completed most of their individual design contribution to co-ordinate dimensions. Crucial data is unintentionally missed, and this can significantly affect the structural design of roof systems.

Mould, moisture, and the building envelope

Mould growth in buildings can occur when mould spores, which are always present in buildings, are exposed to wet or humid conditions for a sufficient length of time and on an appropriate surface to support growth. Water sources can include plumbing leaks, spills, foundation seepage, roof or wall leaks, condensation on cool surfaces such as inside ductwork and on windowsills, etc. In the presence of wet or highly humid conditions, mould spores can germinate within 48 to 72 hours (about 3 days).
