Construction Canada Magazine - November 2007 Vol. 49 No.6

COVER: What may appear to be a breathtaking frozen waterfall is actually an ice dam at the intersection of two roofs. Warm buildings melt rooftop snow and ice, which drip down to the eave and refreeze into dangerous icicles that then melt to create slick walkways below. De-icing systems can put an end to this dangerous freeze-thaw dance by inhibiting the formation of these rooftop glaciers. Sensors and de-icing cables work together to prevent roof damage up top and pedestrian injury down below.

Features

8 ... Roof De-Icing: Dis(solving) slick situations
E. Ada Cryer
Colder climates can dump snow and ice, damaging rooftops and creating hazardously slippery pavements and roadways below. A well-chosen de-icing system can melt away winter troubles, but specifiers must understand how these assemblies can be optimized.

18 ... Elevated Gardening: The basics of growing green roofs
Marie-Anne Boivin, M.Sc. agr.
Green roofs take gardening to a higher level, with environmental and economical motivations that cultivate their design and installation. These vegetated assemblies offer not only green space for building occupants, but also a means for stormwater management.

28 ... Specifying Façade Anchors: Adjustable systems for curtain walls, precast, and stone
Victor J. Yakin
For glass, concrete, or stone projects, the use of a correctly designed, manufactured, and installed anchoring system helps a building maintain its Façade. Newer product types allow for greater flexibility and adjustability in three different dimensions.

36 ... Framing the Great Outdoors: Designing glazing for cooler climates
Don McCann, CSI, AIA Allied, and Alissa Schmidt, CSI, AIA Allied
High-tech glass walls can provide protection and a picturesque view. When considering one’s glazing options, esthetics, noise, and glare are all important factors to consider. However, so is the unfortunately literal impact of birds, local and migratory.

44 ... Partitions and Integrated Design Solutions
Renée L. Gratton, LEED AP
Selecting operable partition systems usually comes down to cost and acoustic needs. Thinking about these room dividers within a ‘green’ paradigm can reap benefits for design teams pursuing sustainability through an integrated approach.

52 ... Going with the Flow: Water efficiency in commercial projects
Winston Huff, CPC, LEED AP
Toilet trouble: Efficient fixtures and other restroom products using non-water or low-flow technologies can help flush wasteful practices down the drain.

60 ... A Quiet Office Environment: Achieving better office interior acoustics with sound-absorbing materials
Robert L. Marshall
Acoustic ceilings and walls can absorb the noise of whirring printers, clacking keyboards, and the office gossip. Softer sounds in the workplace yield happier employees and higher profitability, proving that silence is golden.
