Window walls

Window walls look great and are the newest rage. Yet some experts warn us that this is an unproven technology that may cost their owners a lot of money and grief in the future.

“What does the future hold for condos and how long will they last?” These are by far the questions I am asked most often by condo buyers and owners alike.

Life span of condo building components
Condo buildings consist of thousands of individual components. Over time, due to wear and tear, those components need repairs and replacements. Knowing how old the complex is and when certain components were last repaired or replaced will give you an idea of when they’ll likely need maintenance and replacements again.

The chart at the bottom of this article shows operational life expectancies of major mechanical components of a condo complex over the years. From the sea of available data and through consultation with building experts, I created this chart which I believe provides a fair reflection of maintenance and replacement costs over time to an average high-rise condo building.

The first major component that will need maintenance and replacement is the roof of the complex. It will usually last up to about 10 years, after which it will require maintenance and replacement by the time it reaches 15 to 18 years.

Plumbing/piping will probably be the last as quality and durability has improved over the years, so you can expect it to remain operational for about 50 years. From thereon, it will require maintenance and eventual replacement as well. Standard size windows may also last about 50 years, requiring occasional maintenance such as replacement of screens and sealant. Complexes built of all glass windows need to be addressed in more detail.

Bear in mind that maintenance and repairs to the inside of the individual unit are the direct responsibility of the unit owner. Monthly maintenance fees do not cover anything inside the condo unit. Appliances, heating, air-conditioning, and electrical fixtures inside the unit have to be maintained and eventually replaced by the unit owner.

All glass windows
Because of their appeal, facades of new condo buildings lately have been transforming into glass, often extending from floor to ceiling of each condo unit. It gives condos a more attractive look and is a great selling feature, but building experts have known for quite some time that today’s glass-walled structures are less energy efficient than the stone and concrete buildings that were put up 40 or 50 years ago.

the “pariah” buildings

Indeed, as energy costs climb, glass towers may become the “pariah” buildings of the future. University of Waterloo Professor John Straub (who wrote a noteworthy paper called Can highly glazed building facades be green, was quoted as saying that “With these buildings, both skin and the mechanical systems are going to have to be redone in a 25-year time frame. The concrete structure will be there for a long time but in 20, 25 years time, we are going to see a lot of scaffolding on the outside of the buildings to replace the glazing, sealants and the glass itself.”

Another scientist, Ted Kesik at the John H. Daniels Faculty of Architecture at the University of Toronto, warns that as energy costs climb, the costs of heating and cooling glass towers will increase monthly fees. He wrote a paper called The Glass Condo Conundrum, on the potential liabilities of glass towers. These experts suggest that the maintenance costs of glass skinned towers will skyrocket in 25 years time as the buildings age. With no insulation values, apart from a half inch of glass between two panels, windows will begin to fog up and the costs of replacing entire walls of glass will be prohibitive on high-rise structures that can only be accessed from swing states.

Some experts go so far as to predict that replacing the all-glass outer layers of buildings may become necessary as early as 15 to 20 years from the day that the condo is built, and cost as much as $80,000 per unit. In short, what seems very attractive and appealing to condo buyers today may come to haunt them in the not-so-distant future.

Need for cyclical repairs and replacements
As seen from the chart at the bottom of the article, for the condo building to remain functional, it requires cyclical maintenance and replacement of its major components over time. By the time a condo building reaches 40 to 50 years of age it will have gone through several partial or complete retrofits, likely in stages. Properly governed and managed condo complexes maintain amortization funds - the necessary accumulation of monies over time for replacements of the common elements without undue financial hardships.

Looking into a more distant future, more frequent and repetitive replacements of the vital common elements will give rise to higher maintenance fees in older complexes. In some cases, they will rise to the point of becoming unaffordable to a majority of the unit owners. In extreme circumstances, some condo buildings may end up being wound down either voluntarily, by the unit owners, or through insolvency proceedings commenced by creditors.

The problem of not being able to maintain adequate amortization replacement funds may arise during times of economic slowdowns. Unit owners may experience employment losses rendering them incapable of contributing to necessary fiscal obligations of their condo complex.

This problem may escalate dramatically in poorly governed and/or mismanaged complexes. History shows that buying a condo unit with a small or no down payment presents a huge risk to financially weak unit owners who may lose their units during economic hardships. If the complex is composed of many such unit owners, the whole complex may become underfunded and unable to carry on with the repairs and replacements of its vital elements.

condo complexes’ financial well-being

It is for these reasons that every condo unit owner should be fully apprised of their condo complexes’ financial well-being. The take-it-for-granted assumption that, when you buy into a condo complex, others will take (good) care of its governance and property management, is dead wrong. Every condo unit owner is strongly advised to actively participate in the day-to-day running of their condo complex by closely monitoring and contributing their time when necessary, to all the facets of its operation.

As condos have a finite life span, at least as economic factors relative to their maintenance costs are concerned, the idea is to buy into newer complexes, where their near future expenses and therefore maintenance fees are prognosticated more accurately.

The same logic applies when selling a unit. Don’t wait until maintenance fees become too high. If you do, chances are you are not going to get your unit sold.

The physical life-span
When it comes to physical longevity, the same formula applies to condos as to other high rises, including apartment buildings. The properly-funded and prudently-managed buildings may have a life-span of over a hundred years, or even more. The poorly run, neglected and mismanaged buildings usually end up going down sooner.

Their physical life span depends on quality of governance, prudence of management policies, and the ability of owners to regularly look after their expenses.

Adios, property ladder
The Greater Fool— 14 Auguest 2014 (abridged)
Garth Turner

Virtually all new condo towers thrown up in the past decade have used the window wall system of construction to separate the inside (where you live) from the outside. It’s cheap (as opposed to a masonry exterior), easy to install and quick. The downsides, however, are immense. Walls made out of windows suck at energy efficiency. They’re less durable and the seals always become permeable. Moisture inevitably finds its way in or around. Compared to punched windows (where openings in a brick or block wall are made), these exteriors are flimsy and over time prone to air and water leakage.

And this could be the silent killer of the housing market. No, not just condos. All housing.

Kesik  I know this because of Ted Kesik. He’s a professor of building science at the John H. Daniels Faculty of Architecture at the University of Toronto. Developers hate him. Condo salesguys would happily drive their Panameras and A7s over his toes. And all those horny little hipsters gobbling 500-square-foot units with great views of the next building from their floor-to-ceiling windows should first devour his work.

This week I was in touch with the prof.

a band-aid solution

“Most of these buildings are going to have serious problems in the next ten years,” he says. “First owners will get special assessments for $15,000 or $25,000 delivered to them, which they have to pay by law, to fix these air and water problems. But that’s only a bandaid solution for five or ten years. Then it all comes back.”

Eventually, says Kesik, all these glass condo buildings will have to be reskinned, which not only costs w-a-y more than the recaulking and sealing process, but requires they have to be evacuated. Even if done on a floor-by-floor basis, condo owners will have to move themselves and their stuff out for at least a month.

And this is the easy part. Worse is the financial hit.

nobody wants to buy leaky units

“The best case scenario for these owners is that they would, over time, maybe get their money back,” the professor says. “But more likely, values will spiral lower since nobody wants to buy leaky units. So when people can’t sell, they’ll start to rent them out, and that’s when the spiral really begins. I tell my students these are the places their grandkids will be going to buy crack.”

And what will the impact be on society? How could something as ubiquitous as glass walls come to impact everybody?

“We’ve taken the prime portions of our cities and filled them with this typology, which will certainly lead us into this kind of spiral. This is where things start to get really ugly. I keep trying to tell people this, but the way euphoria works, they forget that somewhere in the future there’s a reef.”

And, of course, it’s not just about condos, but rather the property ladder.

the property ladder

“My Baby Boomer colleagues with houses think this doesn’t affect them,” Kesik told me. “But the simple fact is these young people in condos won’t be able to move up, because there’ll be no appreciation in their units as values fall. So, you know what I tell my friends? I tell them, if you’re ever gonna sell, then sell now. There won’t be a generation coming along to buy them out, and prices will collapse. In fact, this is something that is going to seriously affect two generations.”

Professor Kesik has written something to give your horny children. Seriously. Here it is.

How will our glass condo obsession affect us 20 years from now?
Another university professor, this one from Ryerson warns us that window wall condo construction is going to result in high air conditioning costs in the summer, cold units areas near the windows in the winter and huge replacement costs starting in 10 to 15 years after construction.
