Thermal bridging and healthy humidity levels

from Brent Chancellor
Cold winters bring low relative humidity levels.

 

Ever hear that dry crackle or feel the effect of static electricity as you remove your coat or sweater in the middle of winter? Maybe have dry itchy skin, cracked lips, or even nose bleeds? Why is it that we associate these things with cold weather like we associate holidays and fruitcake? In one word, humidity.

Perseverance of a Community Project

from Adam Kimble

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.

Around the Corner Balcony

from Alexander Krenczik

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

from Matt Capone

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.

Structural Steel and Insulation: An Effective Solution?

from Dieter Hardock

Steel beams which penetrate the exterior wall (and break the continuous insulation layer) represent a detrimental thermal bridge in the building envelope. This situation often occurs in the structural details when a continuous steel canopy or balcony beam cantilevers out from the interior structure.

Steel Structure with Canopy
Steel Structure with Canopy

This penetration to the continuous insulation (CI) layer, is being further considered and addressed in energy building codes such as the ASHRAE 189.1 and 90.1 and the International Green Construction Code (IGCC), which guides codes and standards for both baseline and high-performance green buildings.

Since steel is a highly conductive material (k=50W/mK) / (R-0.003 per inch), a thermal break solution is necessary to reduce energy loss, prevent condensation on the surface, and avoid damaging results to the building. … read more

Using structural thermal breaks in the Southwest

from Victor Yakin

Even though structural thermal breaks were developed for cold weather conditions, design firms in Texas and the Southwest have been eager to learn about this technology. During the first five months of 2013, APCS (independent representative of Schöck) has presented the course on Structural Thermal Breaks 9 times, for medium and large architectural and engineering firms in Texas and Arizona. Many of these firms design commercial and institutional projects nation-wide, as well as for international. These firms have opened their doors to APCS and Schöck to learn more about the causes and effects of thermal bridges, and how to minimize these effects.  Architects, Civil, Structural, and Mechanical engineers have been interested in the scope of thermal bridge consequences such as excessive energy losses, cold slabs, condensation, and even mold occurrences.

If You Can Install a Thermal Break Here, You Can Install it Anywhere!

from Matt Capone

Schӧck Isokorb® has made a (thermal) breakthrough in New York City:  Isokorb ® has been successfully installed in the first thermally broken balcony in the big Apple. Schӧck USA recently received NYC DOB approvals for the Isokorb® module and now a flag has been planted in Manhattan.

In early 2012, we had the first steel thermal break connection at Fulton Street Transit station. And while Isokorb® has been installed globally, with over 10 million thermal break units, over a span of more than 20 years, a concrete thermal break project in New York City is an accomplishment in which we are proud!

The first concrete thermal break in NYC is at the Chelsea Green Development. Located at 151 West 21st Street, the project is expecting to be LEED Version 3 Gold‐certified, and is designed by Architect Stephen B. Jacobs Group and structural engineering by WSP Cantor Seinuk.

Schoeck Canada Foresight 2013

from Christian Witt

The business has been extremely rewarding this past year. The sales of ComBAR® climbed drastically and achieved 3 times the sales volume of 2011. We have also noticed that GFRP is now a common building material and is being specified in a great number of bridge and tunnel structures, especially in Ontario. But also the United States has been an interesting market in 2012. Besides, we have seen a great interest in the future use of GFRP in New Brunswick, Manitoba and British Columbia.

In 2012, we also had an amazing and successful introduction of our Thermal Break Element, the Schöck Isokorb®. Isokorb® has being installed in over 10 different buildings across Canada!  We are now starting to convince architects, engineers and primarily developers and owners about the unique advantages of the Isokorb® to minimize energy consumption, improve the quality of living space and subsequently protect the environment in which we all live and in which our children and their children will live in the future.

A Little Help from our Friends in the UK

from Matt Capone

It was this July while in Baden-Baden for the Schöck 50th party that I got to meet (among many others) our fellow colleagues from Schöck Ltd. UK.  Simon Howland and several others from the office happened to be on a production tour with me. While lagging towards the back of the pack, we got to talking.  I was describing how we are just underway in the US and our efforts to educate about the problems of thermal bridges. They understood, having been in the same situation. Now they are 6 years in the making, with steady project flow, gaining market share and an acceptance by the building community that structural thermal breaks really are necessary to make a proper building envelope.
