The use of glass in architecture sure goes way past thousands of years. It was widely believed that the Phoenicians were the ones who first made glass which happened around 5000 BCE. However, it was not until the rule of the Roman Empire that glass actually started to be a part of architecture. Roman architects used glass in windows in order to get enough natural light into the building with protection from all sorts of elements.
During the Middle Ages, stained glass was popular among ecclesiastical structures. The vibrant colored glasses were used in various Cathedrals and did not only serve as a medium to bring in natural light but also depicted a few religious narratives in a visual format.
The industrial revolution which took place in the 18th and 19th centuries furthermore acted as a turning point for the future of glass in architecture. Innovations started taking place for glass production techniques and allowed the manufacturing of larger and clearer panes of glass. Despite such developments taking place, glass was still only a part of the windows until the 20th century. Modernism brought glass to the forefront by using it for outdoor and indoor curtain walls and large sliding doors.
The Role of Glass in Contemporary Architecture
In contemporary architecture, it is quite visible how advancements in material science and technology have led to even further application of glass which also makes it one of the fundamental building materials. In the late 20th century, due to advancements in manufacturing technologies, it was possible to create high-performance glass. This also includes laminated and toughened glass. These types of glass are specifically known for their durability, safety, and low emissivity which provide high energy efficiency.
With the advent of the 21st century, it was also visible how there were sophisticated glass technologies. The smart glass was developed which changes with light transmission properties or with response to heat, and electricity. The glass could also control the temperature and light entering the room. Such advancements are highly needed to increase the efficiency of buildings. Today we also see large-scale glass facades, glass bridges, glass walls, and even glass floors which were once unimaginable to construct.
There has also been a growing interest in terms of photovoltaic glass which consists of solar cells to produce electricity and also allows transmission of light. The evolution of glass in architecture is hence an ongoing journey and the advancements are sure to keep on increasing as there will be limitless uses of glass in architecture in the coming ages.
Advantages of Using Glass in Architecture
There are several advantages when it comes to the uses of glass in architecture that contribute to both the aesthetic and functional value of the building design. Here are a few of the advantages that can be seen.
Natural Lighting
The transparent nature of the glass helps emit natural light from outside. This further reduces the need for any artificial lighting at least during the day. This can also help create a much brighter and spacious feel in the interiors. Natural lights could also act as mood boosters and provide better productivity and health benefits to the occupants.
Views
Glass can provide an unobstructed view of nature outdoors while also fostering a connection with it. In urban contexts, it can provide better city or street views. This connection will help increase the quality of life and the well-being of occupants.
Versatility
Glass is highly versatile especially when it comes to its aesthetic potential and physical characteristics. It can be colored, textured, shaped, or even layered with multiple materials such that it can provide various design options.
Energy efficiency
Advancements in glass technology have led to low emissive glass production along with smart glass ideas. This can significantly reduce or increase the heat gain or loss. This helps maintain a stable indoor temperature without having any need for cooling or heating agents. Furthermore, photovoltaic glass is another innovation where with the help of light you can generate electricity via the glass.
Aesthetics
The visual appeal of a glass is undeniable. Its shine, transparency, and ability to refract and reflect just give it a unique aesthetic value. When used in facades, it can also create stunning visuals while mirroring the sky. Not to mention how colored, textured, or patterned glass can add aesthetic value to almost any design.
Sustainable Aspects of Glass in Architecture
Glass production has definitely changed from how it was 30 years ago. Today almost 30 percent of the raw materials come from old melted glass. In addition to this, the thermal insulation of buildings has also increased due to the various high-tech mixtures being used. Buildings with high structural glaze could even lead to higher energy efficiency. This could also add as a very important point for sustainability.
There are also infrared and low emissive coatings being used that make it possible for the glass to only absorb a certain color spectrum from light. In combination with the ventilation and shadow systems, glass facades are extremely efficient in both winter and summer to adjust the temperatures. There is also the usage of light ratios-based glazed glass which allows well-lit workplaces. This means that lower usage of electricity is another aspect of sustainability.
Innovative Uses of Glass in Iconic Architectural Projects
The Berlin designer Holger Jahns determined that architects have often used curved glass in their drafts, This technical implementation however only started a few years ago. There were exceptional design concepts that were created such as curved balconies on the Elbphilharmonie in Hamburg, and the roof terrace of the Aarhus Art Museum in Denmark. There is also a sensational view of the city in Taiwan where there is a 17-meter-tall chapel formed in the shape of a female high-heeled shoe and its façade is made up of curved blue glass.
The glass balconies of the Messner Mountain Museum Corones present in Bruneck which is north of Italy are presented in almost a similar curved fashion. Architects of the Bonner Power Tower had also worked with something called as architectural glazing which is indeed an innovative technology. The façade looks like it was made for a single piece. However, when it comes to actual work the individual panes were bonded with each other and were held via connecting points.
Challenges and Limitations of Glass in Architecture
Despite there being a lot of advantages of using glass in architecture there are still a lot of challenges when it comes to proper utilization of architectural glass.
Privacy
While the transparency nature of glass could be a benefit it could also be a disadvantage when it comes to the privacy aspect. Designers must hence consider the balance between privacy and views especially when it comes to residential space or buildings where confidentiality is the priority. Solutions can include the usage of tinted or frosted glass, smart glass, or use of blinds or curtains to block the views.
Safety
Glass is often a brittle material and could pose a possible risk when it comes to the safety of the occupants. However there are modern types of glass such as tempered or laminated glass that can reduce such concerns by breaking into smaller and less harmful pieces or even not breaking altogether.
Maintenance and Cleaning
Large glass surfaces especially in tall buildings are often required to be cleaned regularly in order to keep up their visual appeal. This can actually be quite challenging as well as costly.
Thermal Efficiency
Standard glass is a very poor insulator and can lead to significant heat loss or gain. While insulated and low emissive glass could address this issue, they still come at a higher cost. Using large amounts of such glass could lead to an overreliance on heating or air conditioning systems which impacts energy efficiency.
Bird Collisions
Buildings with a lot of glasswork would pose a danger to birds since they may not recognize the glass as a barrier. Design strategies and certain types of bird-safe glass need to be used in order to tackle this issue.
