Team 3 - Group Project Reflection
As a group, we learned that people bring different ideas to the table; these ideas can be influenced culture, geography, and other outside factors. We also learned the importance of stating your definition and expanding on the idea you are speaking about. As a group, we all had different definitions of intelligent and green buildings, and your definition may take your project or paper in a different direction than someone else's. Technology can be defined differently depending on the time period. Technology is constantly evolving and influencing the design, construction, and operational phases of a building's life cycle.

Group A Week 9 Story Post - Teaching Hospital
Group A:
Mark Odorizzi, Sarina
Tufano, Dung Tran, Nay Ye Oo (Sonny), Alyssia Deutsch, Kerry Milligan
The Prologue:
Discussion of the current hospital situation -
and the shortcomings that will be solved by an intelligent building
This story begins at a run down teaching
hospital named “The Rickety”. Every doctor, nurse, intern, patient and visitor
have been slightly creeped out by the small corridors, the uneven temperature
distribution and the lack of new technologies. The lights were always
flickering, making anyone in their presence feel uncomfortable. Those systems
that did work, made erie noises and thumped randomly at any given time, but
highly prefered to do so in the dead of night. Since this building was
constructed before codes had been renewed, not many rooms had significant means
of egress or sufficient natural lighting which only added to the sinister aura
the building gave off.
In an effort to correct all of the dilemmas
faced by this building and its occupants, a team of an architect, engineers,
project managers, maintenance crews and hospital personnel got together and
made a list of all their individual needs:
“WE NEED MORE ROOM!” - Dr. Milligan shouted
“WE NEED SENSORS TO REGULATE THE AIR QUALITY” -
Mech. Engineer
“WE NEED A DATABASE TO KEEP OUR RECORDS” -
Medical Students
“WE NEED UTILITIES THAT DON’T BREAK EVERY DAY” -
Maintenance Head
“WE NEED QUIETER HVAC!” - Surgeons
“WE NEED FASTER WIFI” - EVERYONE
“WE NEED MORE MOTION SENSORS” - Dr. Milligan
requested
“WE NEED MORE VIDEO SURVEILLANCE” - Project
Manager
“WE NEED MORE EASE OF ACCESS” - Architect
“WE NEED MORE LIGHT!” - Owners
“WE NEED CHEAPER BILLS!” - Maintenance Head
The hospital employee stakeholders in this story are Dr Milligan
(because he was living through the issues and has the most knowledge about what
a better space would look like), the project manager (in order to handle all of
the differing inputs from the stakeholders, Sarina is needed to represent the
hospital as a whole and keep the project on track), and the maintenance
officials (Dung is the one who deals with the hospital facilities on a daily
basis, and has input on how to best design the new space with maintenance
considerations in mind and deals with the creepy doctor who complains about
everything).
The non-hospital employee stakeholders in this story include the
engineers (Structural: Mark wants to make sure the hospital is structurally
sound to handle the heavy equipment and unpredictable live loads), the code
compliance consultants (Hospitals have intricate codes applied to them, so
Sonny is here to make sure we stick to those codes and provide a safe and
acceptable working environment) and the construction management team (Foreman
Rizzi needs to make sure the construction does not interfere with existing
hospital operations, while still being efficient and on time and budget).
The Fix:
Discussion of the steps taken towards developing
an intelligent building and how the new technologies will benefit the
occupants/stakeholders.
Many new technologies will be implemented in
this hospital so that it can provide a better work and teaching environment.
These include code analysis for design and renovation, many types of sensors
for occupancy evaluations, a structural/MEP BIM model for programming and
design processes, a building program database for better record keeping easier
programming and occupational evaluations, as well as robotics for construction
methods and acoustic analysis for renovational aids.
To better be able to ventilate and heat/cool the
hospital, a new high efficiency HVAC system will be installed. Since many
patients and doctors are easily lost track of within the hospital, motion
sensors and camera equipment will be installed. Along with that, databases will
assist in record keeping methods that are highly effective and user friendly.
Additionally, rooms will be made slightly more spacious and more windows will
be incorporated with additions being rendered through BIM and all of its associating
counterparts within the new model’s operation and functions. This will cause
the hospital to become much more efficient in its teaching methods, which will
gain it more patients and result in more money which can pay for the best
hospital equipment and doctors to keep teaching new interns. Overall, the
stakeholders will get large payoffs over the years following this renovation,
the patients will become much more comfortable, and the hospital employees will
be provided with a much better environment in which to work on a daily basis.
In the end, this hospital will also have a much more pleasant facade and no
longer be considered the creepy hospital it was once known for.

Tran - Object-oriented Database
Object-oriented database (OODB) refers to a database model
in which information is presented in the form of objects rather than data such
as integers, strings or real numbers. The database is managed by object-oriented
database management system (also known as OODBMS).
The interest in this type of database come from the needs of
design support systems such as computer-aided software engineering,
computer-aided manufacture or computer-aided design. These applications require
databases that can handle complex data, and provide high performance dictated
by interactive system.
In OODB, every entity is an object. While similar objects
can be classified to classes and sub classes. An object has characteristic
which are referred to as attributes. To be called an OODBMS, it must be a
database management system, and an object-oriented system. Mandatory features
of an object-oriented system are complex objects, object identity,
encapsulation, classes, inheritance, overriding, extensibility and
computational completeness.
The implementation of OODB is similar to relational database
in the 70s. A primary feature of an OODBMS is that accessing objects in the
database is done in a transparent manner such that interaction with persistent
objects is no different from interacting with in-memory objects. This is very
different from using a RDBMS in that there is no need to interact via a query
sub-language like SQL. OODBMS were originally thought of to replace RDBMS
because of their better fit with object-oriented programming languages.
However, high switching cost, higher efficiency of RDBMS when dealing with
simple data and relationship, the inclusion of object-oriented features in
RDBMS to make them ORDBMS, and the emergence of object-relational mappers
(ORMs) have made RDBMS successfully defend their dominance in the data center
for server-side persistence

Dung,
Do you think that object-oriented database will soon replace
relational database? Since relational database management system has many
drawbacks such as the expensive of setting up and maintaining the database
system, fast increase in complexity of information.
Marino,
I agree with you that one of the greatest benefit of OODB is that objects are stored by classes and sub classes which make it easier for navigation, also give the system a better concurrency control.
Shaden,
During my co-op with the construction unit of PWD, I had a
chance to use a database developed by Oracle Project Management to keep track
of issues or change orders with clients. Files can be accessed, downloaded and
edited from anywhere by people who involved in the project. Use of database in
design offices really saved lots of time and money for owner and contractors.

Week 5 - Bach Tran - B4 Underground Intelligent Building
Hello everyone,
Marino Da Costa and I, are going to research and design an
underground intelligent building. Nowadays, people keep competing for
constructing the tallest building in the world. We wonder if building taller
and taller building make any sense. According to the latest report of Council
on Tall Buildings and Urban Habitat, on average, up to 27% of the height of the
top ten tallest buildings is vanity height (non-occupiable height). Take Burj
Khalifa as an example, at 244 m, the vanity height of this building can be a
stand-alone skyscraper. I think this is such a huge waste of money, labor and
materials. Besides, skyscraper like these pose a higher risk for their
surrounding in case of collapsing due to earthquake or other disasters. My
partner and I wonder wouldn’t it be more reasonable to build deeper into the
earth. We believe an underground building will have a higher chance of
surviving disaster and less effects to the environment. In this project, we are
going to look at previously built underground shelters, to learn about the probable
construction materials, budget, as well as architectural and structural designs.
In addition, we will need to identify issues and concerns for building
underground structures, and attempt to integrate intelligent features to make
such building efficient. Some of possible issues are waste disposal, energy
sources, accessibility, building materials degradation, and so on. At the end, we
are aiming to present a Revit model for our underground intelligent building.

Shuyuan,
I would love to have a HVAC system with sensors and controls
for my house. This winter I got a ridiculously high gas bill because of
heating. I had to manually raise the temperature at night and kept forgetting
to lower it in the morning, as the result the whole building was kept heating all
day. I wonder if it would be possible to integrate such sensors and controls to
an existing HVAC system, also will the cost of installing such system worth the
cost of electricity or gas that it can save.
Dung Tran,
I really like the minimalist and futuristic look of this
building. It would be interesting to see how you design and HVAC system for such
building. I concern that a glass envelop like this will require a huge amount
of heat in the winter. In addition, you might want to think about a security
system or something that can ensure the privacy for the occupants if the
building is to be built in an urban setting.
Allison Abad,
I am a big fan of Elon Musk and his ambitious vision of
human living on Mars. I think finding a building method on Mars would be a very
challenging task. I still think that it would be more realistic to have some astronauts
on Mars to control all the robots and drones. In addition to limited energy
sources, Mars is infamous for intense dust storms, thus you might want to take
that in consideration. Good luck on your project!
Sensors and Controls for HVAC Systems
Group Members: Shuyuan Zhang & Shaden Dahroug
The following project was selected to research
based on the interest and knowledge of the importance of HVAC systems within a
building since it’s one of the main contributing factors of energy consumption
within a building, whether during the summer or winter season or even spring
since an HVAC system is required all year around to maintain the building’s
condition to achieve comfort of occupants within a building, while maintaining
indoor air quality. As sensors may be used to increase energy efficiency, it’s
also important for maintenance of the required indoor condition as non-efficient
sensors may lead a building to overheat or overcool, leading occupants of the building
to feel uncomfortable and that may impact their productivity within a work environment.
Sensors and controls for HVAC systems is
believed to be an important aspect of an intelligent buildings, because of its
technological features that doesn’t require manual control from humans in order
to maintain its requirements, where it’s control is achieved through sensors
that only require implementing the program of the sensors with the building requirements
to do its job of maintaining the buildings indoor air condition for occupant’s
comfort.
The research will be focused on how sensors
collect data for an HVAC system, and how the equipment or system process the
data to control the indoor air conditions. In addition to exploring the advantage
and disadvantage of each sensor to determine which would be the most relevant
for an intelligent building to achieve maximum comfort of occupants and energy
efficiency. In addition to determining what effects the performance of a given
sensor.
The following sensors listed below are the
sensor that will be researched for this project, while other parameters that
will be put into consideration for the following project will be trying to
understand the initial and maintenance cost of the following sensors as those
are influential factors for an owner when selecting most component within a building.
o
Carbon-dioxide emission sensor
o
Occupancy sensor (movement)
o
Radiation sensor (heat)
o
Traditional temperature / humidity
sensor
A model will also be created for research purposes
to determine the relevance of our findings for the research, and that will be
achieved through using eQuest for energy analysis to have a closer look at
which sensor may truly be more energy efficient compared to the other sensors
selected for research.
The process of determining the relevance of
our findings for the project will be a challenge as eQuest may not be enough for
this evaluation, and that may lead to requiring database expertise in order to
create a database to determine the relevance of the findings of the project.

Dung
Tran,
A life on mars sounds interesting, and your
project is very interesting but it leads me thinking how many spaceships and
trips will this require for building one place “let’s say a house” and what are
the environmental impacts of those spaceship as they leave earth and go into space,
and since automated construction will definitely increase the traffic in space,
I wonder if that will have an impact on the environment in space. I would also
like to comment about your problem statement it shows that you have thoroughly thought
the challenges that may come with your project.
Best of Luck on
your project.
Malik
Anibab,
I
find the scope of your project interesting because it questions whether a
building can be green and intelligent or just intelligent or just green. Probably
increasing a building’s intelligence may be increasing a building’s energy
consumption in some sort of way, but there is probably methods of using plants
for energy production, where a building feeds energy of itself.
The
following links below are articles about the BIQ building which is located in
Hamburg, Germany. The building is interesting because it has double skin to
make the building green, where the second skin is made out of a bioreactor. Thought
of sharing since this may be helpful with your research.
Best of Luck on
your project.

Zac
Arnold,
It’s
intelligent of you and Mark to take advantage of the project and choose Revit
as a project to increase your familiarity with its use and try to determine its
flaws through experimenting it yourselves which is an important thing to do,
because you only get better by practicing using the software more and more. In addition,
how you considered the scope of construction business as whole when it comes to
general contractors, subcontractors, owners, etc.
Best of Luck on
your project.
