This document describes a Microsoft Excel-based analytical tool developed by Mafraha Jahan to assess the energy performance of educational buildings. The tool has two sections: an initial assessment screen for administrative personnel and detailed analysis tabs for facility/engineering personnel. It has 17 tabs for billing information, temperature profiles, HVAC details, and analyzing 12 potential energy performance measures. The tool helps prioritize energy usage sectors, propose measures, and calculate annual energy/cost savings and paybacks to identify the most economical measures.

PROBLEM STATEMENT
The analysis of Energy Performance Measures (EPMs) performed by
the facility or engineering personnel of an educational building can be
complex and requires significant time and detailed effort. The
assessment performed by them when compared with the other options
in an educational organization, may often reach to bottom priority
level. To get passed over this situation a Microsoft Excel based quick
and easy to use analytical tool is developed which is initially intended
for the assessment of administrative personnel and then again it is
extended into detail analysis for the facility or engineering personnel.
SUMMERY
Microsoft Excel based Analytical Tool is divided into two
sections as follows: i) Initial assessment screen for
administrative personnel and ii) Detail analysis tabs for facility
or engineering personnel. This tool has 17 different tabs: initial
assessment screen, billing information tab, monthly
temperature profile tab, Heating, Ventilation and Air
Conditioning (HVAC) information tab, Energy Performance
Measures tabs (EPMs): EPM-1, EPM-2, EPM-3, EPM-4,
EPM-5, EPM-6, EPM-7, EPM-8, EPM-9, EPM-10, EPM-11,
EPM-12, and economical analysis tab.
THE OUTCOME
1. Energy usage sectors are prioritized and ranked based
upon potential savings and building existing condition.
2. Energy performance Measures (EPMs) are proposed for 7
energy usage sectors: heating, cooling, ventilation, water
heating, lighting, office equipment and miscellaneous.

4. PROBLEM STATEMENT
Automatic controls play an ever increasing role in a human life.
The distinct characteristic of automatic control is that it reduces the
human operator. One such gadget is the fan. Fans are generally
available with speed control; depending on the requirement the
speed is set. Usually, when the temperature is low/high the fan is
operated with lower/higher speed. This is done manually using
human. In this project an automatic control solution is suggested to
control the fan speed based upon the surrounding temperature.
THE PROJECT
1. A temperature sensor (LM35) senses the room
temperature and gives the analog input. 2.
2. The analog input is converted through the ADC to
digital output by PIC16F8777A. This digital value
displayed on LCD.
3. PWM module generates the pulse in which the pulse
width varies according to the AD converter output.
4. The generated pulse acts as the input to transistor
BD135. Finally the variable output voltage is used to
operate the fan.
THE OUTCOME
1. Developed an automatic fan system that can change the
speed level due to the environmental temperature change.
2. Generated feedback with the help of LED indicator in
order to display the change of the speed of the fan.
3. 3. Additionally, this automatic fan system was able to
preview the status of the temperature level by using

5. Programming a SCARA Robot for a Manufacturing Cell to
Assemble & Produce Medical Devices
PROBLEM STATEMENT
A single cell manufacturing machine setup using TMB 100 SCARA
Robot can be programmed according to requirements to perform
certain processing functions. How a robot operation for making a
single manufacturing cell can be made faster using an efficient
algorithm is described. The Primary target of this project is to glue
three parts together to produce a small medical device with limited
human intervention.
THE PROJECT
There is three different trajectory actions required.
1. First operation is to glue two parts second operation is
the glue drying time of the first two parts.
2. Third operation is to glue the third part with the dried
two parts. A buffer part is created and get ready for the
third operation by utilizing glue drying time.
3. Then again it performs 1st and third operation
sequentially.
In this way the process is maximizing its throughput and
minimizing the production cycle time.
THE OUTCOME
For multiple part-type operation in this single-machine cell,
an efficient algorithm was provided that simultaneously
optimizes the robot movement and part sequencing
operation. The proposed enhanced sequence is three time
faster than the traditional sequence.

PROBLEM STATEMENT
To assess how much energy is consumed by a typical Campus
Office building and to propose potential energy conservation
measures that can be implemented to save energy to make the
building more energy efficient, reduce utility bill and carbon di
