Attic Ventilation and Moisture Research Study

By |

This study looks at the level of mould growth in wood-framed buildings constructed in coastal climates, particularly on the roof sheathing of ventilated attics. It includes those buildings that fully comply with code requirements without significant defects, and evaluates the factors that lead to moisture collection and mould growth in attics.

Guiding Teams by Hygrothermal, Energy, and Thermal Comfort Analysis while Managing Uncertainty

By |

Managing uncertainty is core to all engineering analysis of building performance. Effective solutions are established when managing the risks associated with designs are balanced with the benefits to the clients and end users. Many engineering disciplines address uncertainty with statistical analysis, such as limit state design in structural engineering, where the probability of failure, loads, and other design parameters are stochastic variables.

Canadian Window Wall – Design Challenges and Opportunities

By |

One of the defining characteristics of new high-rise residential apartment building design in Canada today is the thermally broken, open-back aluminum frame ‘window wall’ building envelope system. Until recently, Canadian building codes and Canadian and North American fenestration standards have not recognized window wall as a distinct cladding system.

Thermal Performance of Building Envelope Details for Mid and High-rise Buildings

By |

The reduced thermal resistance due to thermal bridging through steel and concrete framing can have a significant impact on the whole building energy performance. Uncertainty about the thermal performance of the building envelope can lead to inefficient design of HVAC systems, building operation inefficiencies, inadequate condensation resistance at intersections of components and compromised occupant comfort.
