Materials: tempered glass

-

 After doing some research, I came across a type of glass that is often used in glass architecture. It is called tempered glass. 

How is it made?

Glass is tempered according to a well-established procedure in which raw glass is heated to a temperature of approximately 100 K above the glass transition temperature Tg in a tempering furnace and then quickly cooled by air quenching. In contrast to annealed glass, this gives the glass a residual stress state that protects the surface from compressive stress and increases its strength. (Dix, Schüler and Kolling, 2022)

According to (Schneider, et al, 2012) Tempered architectural glass's exceptional mechanical strength and resistance to heat breakage make it especially suitable for use in contemporary structural, architectural, and solar applications. Glass is being utilized as a genuine structural element in addition to being a cladding material for windows and facades. Glass is bearing higher and longer-term structural loads, and holes are experiencing even higher local stresses.

In conclusion, I think this material is adequate to the result that I want and to reach the sustainability goal.

Since my project is derived from industrialism, we need to first ask what is industrial architecture? According to Hohendal, Kristin (2022), The design and construction of structures to support the requirements of the industrial sector is recognized as industrial architecture. The safe movement, distribution, and production of goods and labor are taken into account by the industrial world's architecture, which employs a variety of building designs and styles. I also found that this type of architecture is often characterized by; large windows, large open floor plans, and high ceilings, built to safety standards (Hohendal, Kristin (2022)). Since I am choosing to do a library/study space, I thought it would be a good idea to put the industrialism theme in a material context, more clearly in the materials used. I will use steel, concrete and glass for the cylinder in the center of the building since it is the part that holds everything together. I will also use steel and concret

Site plan analysis

                   2D picture of the site I chose this plan because it is close to the river yet far enough in case of floods. It is a 20m/20m square, which makes it 400 m². However, the Riad as a building will only be 255m².  This area is a village called Imlil. Which was severely damaged by the last earthquake in September 2023. According to Khatla (2023). Nearly 6000 houses were destroyed whilst 20000 were partly demolished. Site from a Google Earth 3d perspective: 3d perspective of the region using Google Earth: Analysis of the natural aspect of the Imlil area: Imlil is situated at the head of the Rehraya River on the northern slopes of the Toubkal Massif of the High Atlas Mountains of Morocco. It is at 1700 metres above sea level in a widening of the valley where three tributaries join the Rehraya. It is in many ways untypical of Berber villages in that it is situated in a valley "basin" rather than on the steep valley sides and much of it lies below, rather than a

This structure is what I find to be the most gorgeous one in the United Kingdom, alongside the best in the world, it is a prime pillar of Gothic Architecture. A fire broke out at London's historic Palace of Westminster in 1834. resulting in burning it down to ashes. The fire provided Britain with an opportunity to replace what was seen to be an antiquated, outdated, disorganized collection of government buildings as well as to construct a Gothic Revival monument that would symbolically represent the UK's global leadership and the origins of modern democracy. (Fiederer, 2016) The Palace of Westminster Picture by Alex brown. With the help of A.W.N. Pugin, Sir Charles Barry created the current Gothic Revival structures. The cornerstone was placed in 1840, construction started in 1837, and it was completed in 1860. ( The Editors of Encyclopaedia 1998 ) This iconic structure has always fascinated me for its style, I think it is the closest Gothic revival structure to what through h
