Refrigeration system helps Longo’s earn LEED gold

The cost-effective and environmental benefits of incorporating a glycol system on the retail side of Longo’s Supermarkets made the decision to use the same in its new distribution centre an easy one. It is also one of the design elements the Vaughan, Ont., company is using to achieve Gold under Canada Green Building Council’s (CaGBC’s) Leadership in Energy and Environmental Design (LEED) system.

Affordable Shine: Reflective alternatives to diamond-polished concrete floors

The sheen of the floor in an Edmonton Value Village store may look like polished concrete, but it is, in fact, neither polished nor concrete. The surface material is actually a bonded topping—a relatively soft cementitious material used as underlayment for carpet or vinyl tile, which would not normally be considered ‘shinable.’ Instead of the labour-intensive finish made by polishing it with fine diamond abrasives, it was honed with only medium-grit abrasives, hardened with an advanced-chemistry densifier, protected with a breathable sealer, and buffed to a near-polished shine—a much more affordable treatment.

Plaza Deck Restoration: Principles of drainage and waterproofing

Plaza deck waterproofing typically requires replacement at some point during the building’s life. Restoration of the waterproofing system over occupied space poses many challenges, both in design and construction. Typically, plaza decks now being subject to restoration were constructed many years ago and do not include subsurface drainage or adequate deck slope at the waterproofing membrane level.

Specifying construction vibration requirements

Ground-borne vibration can be produced by various common construction activities, including caisson drilling, piledriving, and soil compaction. In extreme cases, such vibration produced at a construction site has the potential to damage buildings or structures outside the limits of the site; at the very least, it creates an annoyance or nuisance in nearby buildings. A clear understanding of the potential hazard is important.

Planes, Trains, And automobiles: Developing noise isolation for Calgary’s science centre

After 44 years at its 11th Street SW location, Calgary’s science centre has moved due to a lack of expansion space. The new Nose Creek Valley site allows room for a facility that is double the size, and has room for expansion. However, the new site presented challenges for designers. It is in line with the main north-south runway at the Calgary International Airport, and the planes that land heading north fly over the site at a low altitude.

The art of specifying historical roof restoration

Historical buildings are central to Canada’s character and culture. Safeguarded at the federal, provincial, and municipal levels, these sites are granted special designations that dictate the manner in which they must be preserved and restored. In addition to the strong mandates of official heritage conservation, owners and interested parties often have a desire to preserve buildings’ historical integrity—both architecturally and aesthetically.

Sustaining a KEE standard for roofing membranes

Ketone ethylene ester (KEE) is a flexible, high-molecular-weight thermoplastic co-polymer. When properly compounded with polyvinyl chloride (PVC), the resulting single-ply membrane can be bonded or ‘fused’ to itself with hot air, requiring neither torching nor adhesives. Among its many performance benefits in roofing assemblies, the polymer promotes chemical resistance and remains highly flexible with age.

Steam shower systems

Steam therapy is far from a new phenomenon. For thousands of years, many different cultures have used the healing powers of steam to soothe the body and relax the mind. However, modern societies are now rediscovering for themselves the many benefits of steam and reinventing the ways in which people experience it. A growing number of owners and managers of commercial and institutional properties have embraced steam therapy—hotels and resorts, golf and health clubs, day spas, and timeshares.

Security: From cards to cell phones

Security is complicated. In any given facility, there are multiple openings to secure and multiple people who need access. Varied layers of clearance, employee turnover rates, and a long list of other factors play a role in dictating exactly which credential solutions make the most sense. Whether it is a key, card, biometric device, or multi-factor authentication, a credential system provides access to spaces or services within a facility.
