As a student for Digital Building Concentration, this is a required courses for me, before I decided to take this concentration, I was really confuse about what is concentration is related to, and what kind of job I should looking for in the future based on this concentration. I went to ask Prof. Mitchell, he told me that this concentration is based on BIM, there is a position in the company called BIM coordinator, this might be one of the position I can consider in the future. Therefore, I thought this might be a concentration which can help me to prove the skill on how to draw BIM model, such as Revit, AutoCAD, etc.
After take this course, I have a complete different understand about this concentration, how to draw BIM model is only a very small part for this concentration, we only had one assignment is related to Revit. Other than that, the main purpose for this course is help us to understand how to use BIM technology to improve the building in the future, not only for user experience, such as Sensors, green building, life cycle, etc. But also during the construction process, such as 3D printing, Robotics, laser scanning, etc.
Besides, there's anther very important part for the study of intelligent building --- Data Analysis. In this class, we learnt what is relational database, and how to use Microsoft Access to create relational database. Actually, before this I class, I have already took the other two class related with database, one is INFO 210 --- Database Management Systems, and INFO 203 --- Information Technology for Engineers, during those two classes, I learnt about database design techniques using the entity-relationship approach, techniques of translating the entity-relationship diagram into a relational schema. But that was just based on the basic theory about database, different with that, during AE 510, we were asked to create a real database, and this time, instead create by hand drawing, we need to create a relational database by Microsoft Access, although that assignment took me a lot of time to do the research, and gather records, but I think that was a really good experience for me to understand database more deeply.

B5 - Object Oriented Databases - Haoying Ye
Object oriented databases is a database that has the ability
to take inputs and reflect them into outputs, it deal with specified objects,
and follow specific methods. It represents and computes the data collection
into an object that can be used within a computer program. This method
of design primarily consists of two characteristics; Attributes (a composition
of integers, strings, and real numbers that are stored as a record) and
codes (algorithms that define an object with the use of attributes as the data
source). And how it works is that we have objects stored on the
database that reference the ability to develop a product, which can be saved
and stored again as a new assembled object. This new object can be recalled
later easily without reassembling it again.
Compare to Relational databases, OODB designed to work with
images, videos and 3d objects, instead of integers, character strings and
simple text facts. In addition, RDB organizes data in tables that are already
installed and stored, while OODB has the ability to develop new products based
on the stored objects and data. Object Oriented Database haven’t become
popular, because OODB requires special kind of programming language and a
little bit not user friendly, but RDB is easy to use for non-specialized users
and can be programed by non-expert users.
Object oriented databases should be used for complex data
relationship, such as, CAS Applications (Computer aided software engineering, CAD,
computer aided manufacture), Multimedia Applications, object projects that
change over time, commerce. The reason for that is Object oriented
databases don’t require assembly and disassembly saving coding time and
execution time to assemble or disassemble object, it reduced paging, easier
navigation, works well for distributed architectures, less code required when
applications are object oriented.
On the other hand, Object oriented databases have lower
efficiency when data is simple and relationships are simple, late binding may
slow access speed. Besides, there are more user tools exist for RDBMS, standards
for RDBMS are more stable, support for RDBMS is more certain and change is less
likely to be required.
If the database of objects can be regulated, companies and
designers will have an updated catalog of different parts and systems that are
up to code and accepted by a larger variety of clients. This would allow for a
more effective interconnected database system.

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.

What
are the possible future advantages of Revit/BIM
In 21st century, people
have started to get rid of the hand-drawing, and BIM is going to be a major
innovation in architecture and engineering industry, there are numbers of
reason behind the increasing acceptance of Revit in the future:
ü
Revit
parametric modeling is a really good tool for us to have a preview of future
home in 3D BIM Modeling.
ü
In
Revit, all the building components are connected to each other intelligently,
that means, whatever we change in the Revit model, the software will always updates
the related component automatically, it decrease the time for use to change the
design, and no repetitive tasks.
ü
Revit
produces accurate material quantity take outs as a by-product, with less-efforts,
which helps the contractors and owners to determine the budgets of the project.
ü
People
don’t need to spend a lot of time and papers to draw all the drawings and
sketches, through BIM, all the building design and precise calculations can be
done by the software. Most important is, we can save all these drawing
digitally in the hard drive, instead of a great pile of paper
Besides, I think one of the
biggest impacts that BIM will have on the industry in the future is the changing
nature of the profession and those employed in it. However, this happened when
2D drafting software became popular decades ago, and the industry evolved to
adapt to this new technology, as it will with Revit/BIM. At this point, AutoCAD
is still used widely, but as BIM becomes more popular, it will become the go-to
software for most firms to generate drawings and intelligent information about
the model. As such, employees who are familiar with BIM programs will become
highly sought after and employees that do not have such experience will find it
harder to get a job. However, at least for the near future, the industry
standard remains 2D drawings, and many companies only use BIM to generate these
drawings

This chapter
starts off introducing the advantages of BIM models for owners and facility
managers:
1.
Increase
building performance through BIM-based energy and lighting design and analysis
to improve overall building performance.
2.
Reduce
the financial risk associated with the project using the BIM model to obtain
earlier and more reliable cost estimates and improved collaboration of the
project team
3.
Shorten
project schedule from approval to completion by using building models to
coordinate the prefabricate design with reduced field time
4.
Obtain
reliable and accurate cost estimate through automatic quantity takeoff from the
building model,, providing feedback earlier in a project when decisions will
have the greatest impact
5.
Assure
program compliance through ongoing analysis of the building model against owner
and local code requirements
6.
Optimize
facility management and maintenance by exporting relevant as-built building and
equipment information to start the systems that will be used over the life-cycle of the facility.
Through parametric
modeling, changes to the BIM model harmonize with existing infrastructure in
order to reduce construction delays and deliver on time milestones. Besides,
through 3D BIM model, building owners can determine how the MEP systems
interact with the telecommunications equipment and distribution lines before construction,
this allows for actual simulation of
maintenance methods that will be used when the building is in operation.
BIM allows the owner to determine the
reduction in cost of operations and carbon emissions of green systems through
energy analysis and energy conservation software. Owners can also determine how
glazing, which allows daylight into spaces, affects the heating and cooling
loads and see the variations in building performance as a result.
BIM and 4D tools
can make what-if design explorations, which is far easier and more visible
economically than traditional use of real-time and highly rendered walk-through technologies.
Although BIM has a
lot of advantage, it is still just a software, a set of technologies and
evolving work processes, it cannot replace management, project team and work
culture. Before an owner try to adopting BIM, they should perform a pilot
project with a short time frame, small qualified team and a clear goal. During
the process of the pilot, it’s always best to do a dry run and make sure the
tools and processes are in place to succeed.

Robotics
Robotics is the technology and knowledge that used for
design and application of robots. It’s an interdisciplinary research area:
-
Mechanical
Engineering: methodologies for the study of machine in static and
dynamic situation
-
Electrical
Engineering: design of sensor, actuator, interface, control algorithms
-
Computer
Sciences: software, vision, intelligences
-
Mathematics
-
Biology
Thousands
of years, human are burdened by heavy labor. And today, there is a trend for us
to solve the problem step by step since the robot invented. By a general
agreement, a robot is a programmable machine that imitates the actions or
appearance of an intelligent creature --- usually a human. Implementation of
the robot is automatic machine device. It can accept human command, and can run
a pre-arranged program, also based on the principles of artificial intelligence
techniques to develop programs of action. Its mission is to assist or replace
human work, such as manufacturing, construction, or dangerous work:
-
Industrial
robot: the carrier robot hold Lamborghini in the production line.
-
Civilian
robot: help us do job in everyday life.
-
Military
robot: help the army to avoid death in battle and beat the enemy
efficiently
For
the future develop, robotic engineers is designing the designing the next
generation of robot that can look, feel and act more like human. Realistic
looking robot with embedded sensors will allow robots to react more naturally
in real life.

AI (Artificial Intelligence) & Future
Artificial intelligence is to use computers to analog and
instead of human brain. The advent of computers has made artificial
intelligence a major breakthrough. The computer can not only replace some of
the human brain function, but exceed the human brain greatly speed and
accuracy. It can not only simulate part of analysis and the comprehensive
function, but is getting to display a certain characteristics of consciousness.
It really became an extension of the human brain.
AI makes our society much richer than before. Because it
makes the same labors can produce more products within same amount of time. Also,
AI makes our world become smaller and smaller, the long distance communication
become possible. Today, production, trades, finance, education, and politics
become globalize.
On the other hand, AI also bring some hidden, the smart
phones, auto-drive cars and medical robots are coming, we are in the revolution
of AI, our life is changed by AI stealthily, it makes us enjoy the comfortable
life and forget the basic abilities, those abilities which we hardly use them
will become vestigial when humans are developing.

3D Printing & Future
Printing is a process for reproducing text and images,
typically with ink on paper using a print press. 3D printing is a process of
making a tree-dimensional solid object of virtually any shape from a digital
model. This technology is really helpful
for to make manufacture products, because there are some products or models are
imaginative and fantastic, their structures are complex, and often have many
holes in side. Traditional machining techniques, which mostly rely on the
removal of material by methods such as cutting or drilling, because the tools
are not flexible enough to cut the material inside, even some of them can be
machines, the efficiency is very low.
Now it is achievable to produce such a complex product by 3Dprinter. The
3D printer is like a traditional printer, it is achieved using an additive
process, where continuous layers of material are laid down in different shapes,
the printer sprays heated plastic powder to form each lay, that’s why 3D
printing is a kind of additive manufacturing.
In the future, 3D printing will become more commonplace, because
the entire process produces much less waste than traditional manufacturing
where large amounts of material have to be trimmed away from the usable part.
