For the term
project of this class, our group chose to do the research about “Day lighting
Technologies in Intelligent Building”. Day lighting in a building utilizes
available sunlight by manipulating window placement, window fixtures, and room
dimensions to maximize natural light in a space. Using day lighting can minimizes the need for
lamps and overhead lights and the energy required to power artificial
lighting. Effective day lighting
techniques can also:
- - Balance heat gain and loss
- - Control glare
- - Cut energy costs
- - Create a comfortable environment within any building
I am interested in this topic because during my coop
experiences, I saw a lot of company point out in their proposal, that maximum
the daylight using is their emphasis on design. Therefore, I think how to use
daylight and combine it with building design will be a very important topic in
the future.
This time we
are going to introduce three different day lighting technologies:
- 1. Lighting sensors/BAS
- 2. Window makeup/varying opacity
- 3. Passive day lighting: lighting tube/fiber optic lighting.
Each of our group member is going to choose one of the
technology, and do the research based on the case study about how this Technic
has been used, what kind of tools is necessary for it, and how many energy it
will cost. Besides, we are also going to consider about how to provide the training
and maintenance for each technology.
On the other hand, since the biggest reason for us to
consider on using the day lighting is to save energy, therefore, at the end of
the project, we are going to compare the energy between these three technologies
and artificial lighting. Personally, I will do the research based on window
makeup/varying opacity. Smart windows are switchable windows which have
reversible behavior toward activators. The activators may be environment or
electricity. These active glazing, change their characteristics due to driven
activators. As smart windows have different types consequently responsive of
different needs, optimizing situation for single need is unlikely to coincide
with the other environmental conditions.
I think the
biggest challenge for this term project is to decide how to narrow down the
topic, although in the outline, we have already separate into three major
technologies, day lighting is still a very broad topic, each Technic has a lot
of different way to use, and sometimes we need to combine different Technic
together for one case, in this process, we might find there are more Technic
that is outside of those three that we listed.

this is a concept I have also seen prevalent in todays society and building design. With the ability to use computer modeling software it has become increasing simple to simulate outdoor conditions. In the past designers had to rely on azimuth and other tedious calculations. Along with their ability to interpret correct results and convey them to a client.
ReplyDeletethis topic is something I will also take into consideration in my home design in order to optimize efficiency therefore reducing cost and increasing ROI for the owner.
