Light and Art

This week in Lecture we started talking about light, and one of the ways that Bill Sherman approached it was to look at it through art, and in particular through the artist James Turrell. This has to have been one of my favourite lectures because I found his art very interesting and thought that it could easily relate to many works of art that I have studied/enjoyed in the past.

One of my favourite pieces of James Turrell that Bill showed was:


Because the way that light hit the block not only changed the colour of it but also gives the effect that it is floating in space.

Another of Turrell’s works that I found very interesting was:


The image on the right shows a wall, that with the right lighting looks as though it is painted white, but is actually an extrusion into the wall painting with a flat coating of white.
This piece seems like one that I would love to see peoples interactions with in a gallery. Common responses to it are people trying to touch the wall to feel the wall, but instead are left feeling as though they are going through the wall. Another, and less common response, was someone that would lean up against it expecting it to be a wall and falling backwards- something I definitely want to witness!

Looking at Turell’s work made me think about the work of the artist Anish Kapoor.

He is most popular for his works related to mirrors-

But the piece of work of his that i thought related most to lecture is

This piece of work titled ‘pregnant’ has the same illusion as the white wall that Turrelll created, with an indent into the wall that is not apparent at first. Kapoors ‘Pregnant’ is interesting as it is all curves and therefore harder to note that it extends backwards, and hard to see how far it goes back because there are no corners to help identify it.

This lecture was interesting because it showed how important light is and how it can change the perspective of the space you are in. The lighting can make a space seem bigger and therefore is important to consider when designing a space.


Assignment 8

For this Assignment, I have chosen my case study to be the Manitoba Hydro Place. It was built in 2005 and was designed by Kuwabara Payne McKenna Blumberg Architects, Smith Carter Architects and Engineers, and Transsolar (Climate Engineers).

It is located in Winnipeg, Manitoba, Canada- one of the coldest cities in the world. It has very variable weather conditions with extreme highs of 40.6°C (105°F) in August and lows of -45°C (-49°F). It has high levels of rainfall (>50mm) during May, June, July, August, and September. There is a fairly consistent average of wind speed throughout the year at around 17km/h to the S, but there has been a maximum hourly speed of 89km/h and a maximum gust speed of 129km/h. Throughout the site there are a lot of possible daylight hours.with the low being 35% in November and the high being 64.5% in July. (Winnipeg Average Climate)

This Psychometric Chart shows the temperatures and their relative humidity to help get an overview of the building’s need. As you can see from the chart the weather fluctuates a lot and therefore there is a need for varying features within the building to accomodate for a wide range of temperatures.

The Building is oriented south and there is a large southern atria, where the air is mixed up and goes through a humidifier/dehumidifier before it enters the building. This atria space is seen as a buffer zone (see images below) between the internal and external conditions so that there are no harsh transitions during the extreme climates.

Through my analysis of the site, I came up with the following set of diagrams:

These are perspective diagrams showing the temperature and air systems that occur throughout the building. In the diagram the blue represents the cool air, the red represents the warm air and the purple represents the geothermal heating/cooling.
This system has a water feature in the southern side of it (to provide humidification and dehumidification when needed), and operable windows that are constantly intaking the cool air from the outside during the winter. This cool air is then heated by the geothermal wells/field in the previously mentioned buffer zone before it enters the building.
Depending on the season- the geothermal wells can either heat/cool the offices on each floor through overhead ‘radiant ceiling slab’ (as seen in the next diagram below).
On the more northern side of the building there is a solar chimney that is only open in the summer; this takes in the excess hot air that rises in the building and allows it to escape. In the Winter however, when the chimney is closed, the warm air is used both to heat the underground garage and to help the geothermal wells heat up new cool air before it enters the building.

This is a diagram to show the impacts at a ‘human scale’; it shows the ceiling slab and its function of heating/cooling a space more clearly depending on the climate.
It also shows the operational windows that are used in the building, which are not intended to solely let light/heat in but they ensure a constant supply of fresh air.
I have included both a picture of the ceiling slab (left) and the windows (right) to help explain the diagram above.


Tour of the Basement of the Architecture School

This week for our discussion we were taken around the basement of the architecture school to look at the pipes and various systems that control our school.

On entering the basement, the first thing that I noticed was the humidity of the space. The change from the cold exterior temperature and the heat that we encountered in the basement was a big change!
One of the things that I learnt from this visit is that the school is split into two parts- the first and second floor (lectures and offices) are a separate unit to the third and fourth floor (studio and more offices). This means that they both have different sets of pipes that go to them.

While looking at the pipes I was very confused as to what was in each pipe and how it was possible that there were so many- and that they were so organised. This was very interesting to see because nothing made sense to me at first glance, but it was clear that they were all in a particular order. They are colour coded to show the continuity of them, and to make it easy to identify what their purpose is for those who know the system at hand.
From looking at the state of the pipes it was easy to see which were the newest ones as they were the least rusty- and we could therefore figure out that the newest pipes were for the sprinkler system which was added in the last decade.

This tour was very interesting to help put into perspective the complexity that can occur in systems, and how many different parts there are to every system.

Mechanical Transfer

This we only had one lecture due to Hurricane Sandy, and in it we talked about the transfer of heat in a house. I learnt a lot about how ACs work and how to add a reversing value to a unit so that it can be used as both an airconditioner and a heater. This was all stuff that I have never thought about the system behind- but reminds me that there are inner systems in everything.

In relation to this class, I think it is interesting to compare all of these mechanical ways of controlling temperature with a very natural one, and my example is Frank Lloyd Wright’s Pope Leighey House.

I just visited this house for studio, and while I was walking through it, our guide was telling us all about the natural forms of heating and cooling that Frank Lloyd Wright implemented to make the house maintain a good temperature but without too much artificial light or heat. I found this absolutely fascinating as we were just studying the artificial ways, but the natural ways can also be very effective if implemented correctly.

The way in which Frank LLoyd Wright was able to make this possible was due to the size of the house and due to the amount of apertures that he had created. Throughout the entire house has a line of clerestory windows along the top part of the wall. These make it easy to create cross ventilation in all parts of the house as it is a continuous range of openings all around the house. In addition to this, there are also many large glass doors that can fully open up letting in large amounts of fresh air. These are helpful as they allow a lot of natural air in, which can be good for cooling the house down. It also helps to provide more cross-ventilation as they are large openings that can allow a large transfer of air at a higher rate than the small windows.

This is an image to show how the clerestory windows work in relation to the large doors that can fully open up. As you can see in the image, there is one vertical wall that is composed fully of these windows, and then they continue to run along the top part of the other walls.

This is a plan that I annotated to show the cross-ventilation that I could see taking place in the house when I went to see it. The only room in the house that does not have two windows on opposing sides of the room is the kitchen, but even this has a large window within it, and a way to make it a private space, which was needed in the 1940s when the house was built.
This creates a great atmosphere in the house as one is so exposed to the external world around the, but they are still in a small, enclosed and cosy space that is kept at a comfortable temperature.

Overall, I found the Pope Leighey house a very interesting case study to look at because of all of the ways it has avoiding paying money for heating and cooling as this is something we are studying in systems.
