High-rise Window Replacement
This presentation will cover window and window wall system replacement considerations, technical challenges, thermal simulation options to optimize current systems, logistics and tips to minimize the intrusion on occupants…
There are many reasons why it might be time to replace those old high rise windows or window wall systems, such as broken and worn parts that are difficult to replace, poor thermal performance, or air tightness issues that affect overall energy performance and occupancy comfort. Persistent water infiltration is a nuisance and can lead to significant damage to surrounding building elements. Many buildings are now approaching an age where window system replacement should be considered. Costs can be significant but new technologies and performance advancements can help directly (energy savings) and indirectly (occupant comfort) offset the capital outlay. Sometimes there are opportunities to leverage thermal modeling to eliminate heating or cooling equipment.
Many window replacement challenges are technical, such as system choice, glass choice, and limitations imposed by existing geometry and surrounding elements. Other challenges appeal to the human side to window replacement. These spaces are peoples’ homes and good communication and buy-in from the owners is an essential part of the window replacement process. This presentation will cover window and window wall system replacement considerations, technical challenges, thermal simulation options to optimize current systems, logistics and tips to minimize the intrusion on occupants.
1. Understand what glazing systems are and how they function as a building wall.
2. Learn some of the most common motivations for beginning a window replacement project.
3. Understanding the importance of owner involvement and communications amongst all parties involved in achieving a successful project.
4. Learn that well executed design, mock-ups, and field review are essential parts of a window replacement project.
