Can Isokorb® be used on balconies with post-tensioned (PT) slabs?

The architect’s goal is to create a beautiful building that functions well over the life of the structure and is within the developer’s budget. Our experience has been that when architects realize there is a good solution for the thermal bridging problems on the building envelope, they want to use it. However, one question that often comes up when discussing the benefits and value added by using Isokorb structural thermal breaks is: Can Isokorb® be used at balconies with post-tensioned (PT) slabs?

Concrete Slab Edges; How Thin is Too Thin?

It’s hard to pinpoint an innovation or advancement in today’s world that isn’t due to improved technology. Building design is no exception. With its continual evolution, the limits and tolerances that we design and construct with, previously deemed “unachievable”, are now continually surpassed with each new building design – shaping it differently, building it taller, cantilevering it further, or designing it thinner.

Perseverance of a Community Project

Sainte-Germaine-Cousin is a project for the community. Located in Quebec, the church of Ste-Germaine-Cousin has come a long way, overcoming an asbestos closure in 2005.

Today, the revitalized church building stands central with a new addition, a curvy, s- shaped structure, of affordable housing with 126 affordable (PAPA type) units and intermediate housing for seniors.

Asbestos within Ste-Germaine Cousin Church presented a considerable financial challenge. After the closure of the church building, it was 7 years later in which construction began with asbestos removal and groundwork for the new addition. However, perseverance has proven successful, providing an exceptional building of great heritage value.

Around the Corner Balcony

News_Design-Engineering_03-2013_470x260px_RGB_Newsseite

Condominiums and apartment buildings can be designed with corner, wrap around balconies to provide dramatic views. These corner balconies are most commonly cantilevered concrete balconies which are a slab extension from the building’s interior slab surface.

Corner balconies provide heightened aesthetics designs as well as ensure optimal sun exposure on the balcony. This is especially important when your balcony faces east, to allow a corner section on the south to provide additional sun exposure during the day. In dormitories, balconies are often used as loggia walkways around the building as an evacuation scenario for a fast and secure escape.

Cantilever Slabs at Stairways and Shafts

Normally cantilevered slabs and edges are considered extensions of the floor or roof levels of a structure. Often times however, conditions require a connection along vertical walls or areas where interiors floors are omitted because of stairways or mechanical shafts. These areas have the same potential problems with thermal bridging since there is an interruption in the continuous insulation layer.

For this Design Break, we explore details of a project in which Isokorb® thermal breaks were used in just such conditions, 15 Leonard Street located in the Tribeca neighborhood of New York City.

Earthquake Considerations for High Performance Cantilevered Balconies

Cantilevered balconies are common in residential structures, yet their traditional design is a slab of continuous concrete passing through the building envelope. This concrete slab balcony creates one of the most significant thermal bridges with excessive heat loss.

As buildings improve with higher performance walls and windows, the amount of heat loss at the balcony slab is increased. Therefore, designers are looking for solutions to thermally separate the interior slab from the exterior balcony slab.

Thermograph1

From a structural point of view, balconies have to resist several loadings conditions like permanent loadings (dead load), variable loadings (live loads, wind loads, snow loads) and rare loadings resulting from earthquakes. Seismic considerations could have a relevant influence on the design of buildings depending on the geographic location of the building (seismic hazard), soil characteristic, stiffness and weight of the building, the assemblies and so on. read more…

The Capital of Efficient Building Envelope Design

Building performance codes have become more rigorous in Canada, especially in the Ontario Province with  SB-10 standards. Architects are looking for more options to meet these code requisites, and projects in Ottawa such as St. Patrick’s, Tweedsmuir and Cathedral Hill are setting the bar.

These three projects are currently in construction in Ottawa, and all share the similarity of using Isokorb concrete thermal breaks, yet they are distinctive in building design and purpose. The St. Patrick’s home is a short and long term care facility, Tweedsmuir a low rise development in the Westboro neighborhood, and Cathedral Hill is a high rise condo/apartment building in downtown Ottawa.
