The Polyisocyanurate Insulation Manufacturers Association (PIMA) developed a research report in response to recent articles questioning the thermal performance of polyiso roof insulation in colder climates. According to “Thermal Resistance and Mean Temperature: A Report for Building Owners and Design Professionals,” polyiso roof insulation R-value shows no significant variation among North American climate zones.
A global design, engineering, and consultancy firm has released a report stating disputes relating to major construction projects in North America decreased in value while the length of time to resolve conflict increased significantly last year.
An ASTM International committee, D08 on Roofing and Waterproofing, is developing a standard for two asphalt products that will help reduce air emissions, save energy, and benefit workers by lowering their exposure to asphalt fumes.
The MacOdrum Library at Carleton University in Ottawa received a 2015 Ontario Library Association (OLA) Library Building Award for its redesign by Diamond Schmitt Architects (DSAI). DSAI partnered with Edward J. Cuhaci and Associates Architects to renew the 1960s-era building.
A project may involve not only general contractors, architects, inspectors, engineers, and developers, but also regulators, city planners, estimators, and many others. This is why technologies capable of facilitating and streamlining document management, sharing, and collaboration are a central component in strategies tasked with increasing construction productivity and efficiency to ensure projects are completed on time and on budget.
Many people believe white noise, pink noise, and sound masking are synonymous, and tend to use these terms interchangeably. However, there are distinct differences between each of them.
One of the strategies employed by architects to increase (or regain lost) glazing area to meet the performance objectives of building energy codes and standards involves using established building envelope elements such as window louvres, fins, and shelves, along with emerging technologies such as vacuum-insulated glazing and panels (VIGs) and electrochromic (EC) glass.
With an aging population and an unmanageable burden on most hospitals, the community health centre is an increasingly in-demand neighbourhood resource. Stretched regional and non-profit finances mean these new facilities are often asked to do double (or triple) duty, accommodating many needs and user groups. The challenge then falls to design teams to successfully integrate disparate building requirements—often under a tight move-in deadline determined by grant and funding deadlines.
HVAC equipment is generally installed on top of the flat roofs of industrial, commercial, and institutional buildings. The maintenance personnel sometimes are exposed to danger of falling if the units are close to the roof’s edges. In this case, a guardrail system is required. How do you know if it is sufficiently structurally secure?
