Award-winning building upgrades set high standard

In awarding the project ‘Bank of Canada Renewal’ in Ottawa by Perkins+Will the Existing Building Upgrade Award, in the 2019 SABMag Canadian Green Building Awards, the jury noted that, “This major rehabilitation and revitalization project has addressed the  many inadequacies with aesthetic sensitivity and restraint.” One of the main interventions is a new “dynamic buffer zone” (a double skin created by adding an interior glazed wall around the perimeter of the building) and a radiant cooling system for principal heating and cooling needs, allowing ducts to be sized for ventilation only. The efficiency of interior space was partly improved by demountable wall systems from Teknion. More details here.

A second Existing Building Upgrade Award was given to the Wellington Building Rehabilitation by NORR Architects and Engineers. Also in Ottawa, and near to the Bank of Canada, the project, “carefully and cleverly reconciles the competing challenges of seismic upgrading of the structure, updating of building services and infrastructure and the constraints of heritage conservation,” according to the jury.

A four Green Globes rating was achieved through the preservation of the building core and shell, connection to the district energy plant, solar panels for domestic water pre-heating, heat recovery units, reduced water requirements, a rainwater cistern, a green roof, and a sky-lit atrium which brings natural daylight into the upper floors. More details here.

Viessmann supplied solar hot water roof panels. The Nedlaw living wall biofilter removes VOCs from the atrium area, and Uponor radiant heating systems are used in selected perimeter floor areas.

Precast concrete industry releases Wall Thermal Performance Calculator

The Canadian Precast Prestressed Concrete Institute (CPCI) has released its new web-based software, “Precast Concrete Wall Thermal Performance Calculator”, for designers that calculates effective R-values for common architectural single-wythe and double-wythe precast concrete wall systems. The software compares the calculated effective R-values with the requirements of various building codes, and provides an easy user-interface allowing for the selection of applicable code and system parameters including concrete thickness, insulation type and thickness, and includes graphical representation of the inputs and outputs that may be printed for the design team and Authorities Having Jurisdiction. The software can be accessed here.

Global 2019 Urban Water Challenge Prize Winners Announced At World Water Week, Stockholm

Hornby Island Fire Hall

Public input leads to resilient construction, low operating costs

Built to replace the existing 2.5-acre site structure, the new 7,500 sq ft, civic/institutional facility consists of a single-storey fire truck apparatus bay and a two-storey fire hall. The project is built to LEED Silver equivalency and the Passive House standard (although not certified) using the Passive House Planning Package (PHPP) software. Predicted thermal energy demand intensity is 13 kWh/m2/year. Predicted total energy utilization intensity is 60 kWh/m2/yr. The high-performance prefabrication wall and roof assemblies provide R values of: Roof – R55; walls – R38; and ground floor slab – R28. Read the full article.
