Using an overhead high-volume, low-speed (HVLS) fan’s bi-directional airflow and elevated air speed is a powerful way to improve ventilation, thereby reducing the concentration of airborne pathogens through dilution. Occupant comfort can be assured in applications ranging from non-conditioned industrial spaces to commercial buildings.

An airtight building enclosure is an important part of a modern building. Airtightness is achieved with an effective air barrier system that is carefully designed, detailed, and then built and commissioned in the field. An effective air barrier consists of a continuous system of materials, components, and accessories, not an individual product.

Adequate ventilation is necessary to ensure acceptable indoor air quality (IAQ) and remove pollutants originating from building materials, consumer products, and human activities.

In masonry cavity walls—a design that has been in use for more than a century—the cavity provides a path for drainage and ventilation and acts as a capillary break.

Except as a tool to connect with one another or conduct research, how important can Wi-Fi really be to design/construction professionals? B.C. expert Stefan Storey has created a system that adjusts ventilation according to the number of Wi-Fi users in a space.

Radon, a naturally occurring radioactive gas, enters buildings through foundation cracks and other openings in contact with soil and rocks.

With an appropriate strategy and design, a naturally ventilated structure can be comfortable for all occupants, including those in a multi-storey building. This article examines how natural ventilation fits into mixed-mode setups, safety considerations for building occupants, and esthetic features, and also explores how it can relieve engineers of issues associated with pairing an off-the-shelf actuator with a standard window.
