The document is a building energy simulation report that analyzes the energy performance of a single-storey commercial building in Waterloo, Ontario. It summarizes the baseline energy consumption and costs, and runs simulations varying the roof insulation, lighting power density, and heating efficiency. Increasing the heating efficiency to 95% reduced annual natural gas costs by $111 and GHG emissions by 15%. Reducing the lighting power density to code standards cut electricity costs by $322 and GHG emissions by up to 8.5% annually. The report recommends energy efficiency upgrades to lower energy use and utility bills.
Building simulation is the process of using a computer to build a virtual replica of a building.
The building is built from its component parts on a computer and a simulation is performed by taking that building through the weather conditions of an entire year.
In a way, building simulation is a way to quantitatively predict the future and thus has considerable value.
Building simulation is commonly divided into two categories:
Load Design,
Energy-Analysis.
The common phrase for building simulation when energy is involved is Energy-Simulation.
amount of energy used is equal to amount of renewable energy created on the site
reduce carbon emissions & reduce dependence on fossil fuels
Buildings that produce a surplus of energy over the year are called “Energy Surplus Buildings”
During the last 20 years more than 200 reputable projects claiming net zero energy balance have been realized all over the world.
NZEB buildings consequently contribute less overall greenhouse gas to the atmosphere than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount. Traditional buildings consume 40% of the total fossil fuel energy in all over the world and are significant contributors of greenhouse gases.
The presentation will include the following topics:
- Fundamentals of energy modeling
- Overview of the eQUEST energy modeling program
- Recommendations for integrating energy modeling into the design process
- Brief description of baseline energy modeling using ASHRAE Appendix G
- Recommended strategies for reducing energy use
- How to review energy modeling results
-Common problems and how to avoid them
The goal of this discussion is to demystify building performance modeling. Computer-simulations give you a more complete picture of how various context and design factors can affect the performance of your space. Modeling information can help you analyze the impacts of your design decisions and determine how to most effectively meet project goals.
Energy modeling is also valuable tool used for code compliance and LEED points. Not to mention the fancy graphics that models produce to show your clientele your commitment to performance-based design.
This discussion will present various opportunities that can arise from building performance simulations with analysis at the early design, whole building, and building component levels. We will examine the following types of analysis:
• Climate
• Daylighting
• Massing and orientation
• Whole building energy usage forecast
• Fenestration design
• Façade development
• Zone level energy performance
• Baseline and design case models
• System selection and optimization

ANALYSIS OF ENERGY CONSERVATION OF AN INSTITUTIONAL BUILDING USING DESIGN BUI...ijmech
Buildings contribute impact on CO2 emission and energy consumption. Electric energy
consumption in buildings is about 40% of the total energy consumption of India. In this work building
simulation technology is used to evaluate a variety of envelope thermal characteristics and low carbon
technology in an integrated manner at the early design stage itself to assist the delivering of sustainable
green buildings with a high rating of performance and energy consumption. Building simulation enables
designer to identify the key energy loads, test their strategies and compare permutation of design strategy
in order to optimize the energy consumption.
Design Builder (DB) software is used to carry out a series of sensitivity analysis on set of design
parameters, with an aim to achieve a comfortable and energy efficient building. Several parametric studies
have been conducted to enable building designers to carry out analysis of energy efficient building model
related to building orientation, construction, air infiltration, natural ventilation, window type, openings,
and lighting. To calculate the energy saving, basic condition of building model is compared with Energy
Conservation Building Code (ECBC) building model. Consider basic condition of building is case A and
condition of building according to ECBC is case B.

A review of advanced linear repetitive scheduling methods and techniquesAsadullah Malik
ABSTRACT
Over the past two decades, significant attention has been focused on the development of advanced scheduling methods for repetitive/linear construction projects. Several approaches have been proposed by various research groups in order to solve specific problems in the scheduling of repetitive/linear construction projects such as high-rise buildings, bridges, pipelines, and highways. Some of these approaches represent milestones in the authors’ researches, and others provide a thorough solution implemented in computer software. This paper is a review of several articles related to this topic, which have been published in specialized journals since 1998. The solution methods for repetitive/linear scheduling problems are various, extending from simple graphical techniques to complex computational and optimization methods, such as genetic algorithms. The methods underlying the different solutions can be divided into three groups: exact, heuristic and metaheuristic. This paper presents an introduction into the different repetitive/linear scheduling problems, outlines the optimization methods proposed, classifies the different approach methods utilized and, finally, areas for future research are suggested.
Keywords: linear scheduling, construction management, repetitive units, optimization, genetic algorithms.
Urban Transportation Planning for the Region of WaterlooAsadullah Malik
This report aims to create models to describe travel behavior and transportation demand within the Region of Waterloo. We apply the traditional four-step Urban Transportation Demand analysis process to tackle the problem. Data collected by the Transportation Tomorrow Survey (TTS) for 2011 is used as base year data to calibrate the models. The data are firstly pre-processed (cleaning, deleting the missing and reduplicative value, etc.), then a thorough Exploratory Data Analysis (EDA) is carried out, followed by developing models for trip generation, trip distribution, and modal split analysis step by step. Also, traffic assignment is discussed.

The Struve Geodetic arc & its future possibilities of being the one (Semester...Asadullah Malik
It is a concept that started in the year 1816 and was carried out by an astronomer by the name of Friedrich Georg Wilhelm von Struve. During the time of Struve’s existence, the distance between two points was measured by measuring poles.
However in order to accomplish the goal that Friedrich von Struve had envisioned - calculating the size of the earth - measuring poles would not be sufficient. To do this a more sophisticated tool would be needed.
Before long the Struve Geodetic Arc was created to do just that. The Struve Arc only ran through two counties, namely Russia and Sweden-Norway. But his surveys, that took place between the years of 1816 and 1855, calculated the very first measurement of a part of the meridian with staggering accuracy. It was the start of topographic mapping and a growing interest in earth sciences. The Struve Arc is a survey triangulation chain which has assisted scientists to map out certain areas and regions of their countries. The Struve Geodetic Arc is currently a joint venture between scientists of various countries who work together in the name of science. Today the Struve Arc survey chain runs through ten countries, namely Norway, Sweden, Lithuania, Moldova, Russia, Latvia, Belarus, Ukraine, Finland and Estonia, and stretches from Hammerfest (Norway) to the Ukrainian Black Sea.

Sustainable Modifications and Innovations using LEED of a Women University in...Asadullah Malik
We as civil engineers deal with a field which is so diverse in its applications. In this project too we dealt with Environmental, Transportation, Material and other aspects of a project.
The continuous search for more sustainable and economic processed solutions has been an important investigation topic of a broad research community worldwide. The resulting solutions can therefore be adapted by the industry thus leading to a more sustainable society. The building industry is not immune to this reality and huge efforts have been done in order to find alternative sustainable building materials and low technology methods, which result in a more sustainable and affordable construction complemented with the comfort standards required nowadays. The CO2 emissions to the atmosphere, energy and water consumptions are some parameters that have significant impact in this equation. Reusing, opting for green building materials (which must be renewable, local, and abundant), retrofitting, choosing low technology methods and techniques are some practices that have given good results in this context.
The concept of sustainability is not limited to buildings.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Dear Prof,
Please enclosed the Building Energy Simulation Report for a single storey commercial building
located in Waterloo, ON. The simulation evaluates and analyses the current energy consumption
of the commercial building and recommends energy saving measures by analysing ASHRAE
Standard 90.1-2016 Energy Standard for Buildings’ regulations and comparing it with the energy
consumption of the same building after certain proposed changes are made.

1.0 Motivation & Introduction
The energy shortage crisis and the rapid change of global climate have become important issues
in the world now a days since modern trends are shifting to more sustainable solutions to save
energy and to reduce the emission of carbon dioxide. Generally speaking, when improving energy
efficiency and adopting the energy –saving design, the advantage is not only providing low
operating cost for stakeholders, but also reducing the negative impact on the global and ambient
environment. This study analyzes the surveyed building integral energy consumption, evaluates
its energy performance, and gives further recommendations for saving energy costs by using
dynamic energy simulation tool eQuest.
Building performance simulation (BPS) is the replication of aspects of building performance using
a computer-based, mathematical model created on the basis of fundamental physical principles
and sound engineering practice. The objective of building performance simulation is the
quantification of aspects of building performance which are relevant to the design, construction,
operation and control of buildings. Building performance simulation has various sub-domains;
most prominent are thermal simulation, lighting simulation, acoustical simulation and air flow
simulation. (Wikipedia Contributors, 2019). Due to the scope and flexibility of its input, eQuest
can implement dynamic calculation method for calculating building energy consumption and
influencing factors of various components, and thus be used in many applications.
The simulation was performed keeping in view that the indoor temperature has to be maintained
at 24.4 ºC while the building is occupied and at 27.8 ºC when it is unoccupied during summers. In
winters it is simulated that the temperature should be at 21.1 ºC and at 17.8 ºC while it is occupied
and unoccupied respectively.
2.0 The Preparation to Apply eQUEST Model
EQUEST calculates hour-by-hour building energy consumption over and entire year (8760 hours)
using hourly weather data for the location under consideration. The input parameters consist of
detailed description of the building, hourly scheduling of occupants, lighting, equipment and
thermostat settings. It provides accurate simulation of building features, such as shading,
fenestration, interior building mass, envelope building mass and dynamic response of different
heating and air conditioning systems and controls. (Hirsch, 2004)
The simulation process begins with developing a virtual model of the building based on
architecture plan. In this study, the details information of the surveyed building is provided.
Alternative analyses are made by changing the parameters of model that could be implemented in
the building. Data required in eQuest is summarized as shown in Table XX, which illustrates the
data should be collected prior to developing simulation of confirmed in the course of modeling.

• Analysis Objective
Clearly understand the design questions that wish to answer by using simulation model. In
this study, the owners are interested in having a preliminary study performed to assess the
potential energy performance impacts of certain characteristics of the design, aiming at an
economic and effective improvement on energy performance.

• Building Site and Weather Data
The building to be studied is a hypothetical new small office building to be constructed in
Waterloo, Ontario. Weather data are downloaded from the eQUEST database.
• Building Shell, Structure, Materials and Shades
eQUEST analyzes walls, roof, and floors of the building in heat transfer and storage effects.
Overall floor area 2700 square feet with one storey. Other architectural details are shown
below:
1. Floor shall be concrete slab on grade. Interior finish will be carpet.
2. Roof type: Shall be flat.
3. Windows: Double-glazed. Frames are aluminum with thermal break. The Overall
window-to-wall ratio is 35%.
4. Interior celling: No suspended ceiling. Floor to ceiling height = 11ft.

• Building Operations and Scheduling
A clear understanding of the schedule of operation of the existing building is important to
the overall accuracy of simulation model. This includes information about when building
occupancy begins and ends, and internal equipment operations schedules. The building is
open from Monday to Friday, and its business hours are approximately from 7 am to 6 pm.
The HVAC system starts running 1 hour before occupancy and shuts down 1 hour after the
business time.
• Internal Loads
Heat gain from internal loads (occupants, lights and equipment) can constitute a significant
portion of the utility requirements in buildings. The surveyed building has a peak
occupancy of about 12 people, providing overhead lighting system with a maximum overall
lighting power density (LPD) of 1.0W/ft2
. For plug loads, the estimated peak load is 0.5
W/ft2
, estimated operating average during business hours is 0.25W/ft2
.
8. 7
• HVAC System
The specifications of HVAC systems are detailed below:
1. During regular business hours, the space shall be fully heated and cooled to
typical comfort conditions.
2. Equips with a single roof-top unit. Overhead ducted air distribution. Natural gas
heating with electric “DX” cooling. Preliminary estimate for supply-fan total-
static-pressure = 2.0 in w.g.
3. Minimum outdoor air intake rate on RTU’s based on 25 cfm/person.
4. Cooling efficiency = 8.5, baseline heating efficiency = 8.0
• Economic
The utility rates are provided to calculate and analyze the annual energy costs:
Electricity = $0.13/kWh; Natural Gas= $0.25/m3
(≈ $0.698/therm)
Besides the key characteristics mentioned above, all of the building descriptions set for the baseline
design are concluded in the project files. After finishing creating a building description in eQuest,
a simulation could be automatically done.
3.0 Simulation Reports for baseline design
After all of the simulations have completed, the designer can visualize the results and reports
through graphical formats, including an exterior 3D view of the simulated building (Figure 3), and
reports for annual or monthly energy consumption and costs.

As shown in the Table 1 and Figure 4, the simulated baseline design consumes 29.094 kWh
electricity for lighting, ventilation, HVAC mechanisms space cooling and others, while 104.92
kbtu natural gas is used for space heating and water heating.
Figure 5 Annual Utility Bills (Baseline)
The utility bills for energy charge the owner for $4514 per year, when the electricity costs accounts
for the majority of the spends. Given the area lighting have a percentage of 37% among electricity
consumption, and 95% of the natural gas is burned to heat up the space, it can be projected that
reducing the lighting power density and heat load can significantly reduce the energy costs.
3.2 Benchmarking
After converting the electricity and natural gas consumption into one unit, the surveyed building
tends to have an annual total site energy use of 74.6 kbtu/sqft (Detailed in Appendix) under the
baseline conditions. By comparing to the benchmarks provided by the US EPA’s “EnergyStar for
Buildings: Target Finder” tool, the Site energy use intensity (EUI) is ranked above the 75th
percentile.

4.0 Simulation Experiments of Variables Control
To have a further understanding of how parameters independently affects the building performance
on annual energy cost and annual GHG emissions, series of simulations are carried on examining
the difference between baseline design and experimental groups. This study the following three
building parameters as the variables:
1. Roof R-value.
The insulation value should have the impact on space heating. The higher the value is, the
temperature difference between indoor and outdoor is smaller, hence effectively
preventing the unnecessary heat transfer through building roof.
2. Lighting Power Density.
LPD has a noticeable impact on electricity consumption.
3. Heating Efficiency
Improving heating efficiency carries reduction on gas use for certain heat load.
Table 2 displays how each parameter varies in ten simulations. It should be noted that all the other
building characteristics and conditions, despite of selected variables, are identical among the
simulations.

5.0 Trends & Validation
Figure 7 Monthly Energy Consumption (Baseline)
From the report of monthly energy consumption by end-use, the graphs indicate significant
variation according to seasons and weather for both electricity and natural gas usage. Between
May and October, the cooling system operates, hence causes the electricity costs to grow.
Electricity consumption peaks during the hottest July. Meanwhile, gas consumption increases in
the cooler weather due to heavier heat load. Based on these trends, the simulation result for baseline
design could be considered reasonable.

It can be deduced from the simulation results that the least Total Site Energy was seen during the
last simulation when the Heating efficiency of the furnace was increased to 95%. Whereas the
maximum Total Site Energy was observed during the baseline year.
Figure 9 Cost comparison of Natural Gas vs Electricity
Graph in Figure 9 was generated through data generated by eQuest Simulations shows that the
increasing the furnace efficiency to 95%, the annual natural gas cost was reduced, leading to an
annual savings of $111.
It also shows that by reducing the Lighting Power Density to ASHRAE Standard 90.1-2016 Energy
Standard for Buildings’ regulations for Office buildings, annual savings of approximately $322 in
the Electricity costs was observed.
However, an interesting trend was observed in the Natural Gas cost which rose for Simulation 5,6
and 7 where the Lighting Power density (LPD) was reduced. This was probably due to the fact that
since the LPD was reduced less heat was generated by the Lights in the building and that gap was
filled by the furnace. Consequently, to maintain comfortable temperature in the building the
furnace had to run more and consume more natural gas, thereby increasing the cost of natural gas
by $28 annually. This cost though may be insignificant but has an interesting reasoning behind it.

5.1 GHG impact
Given the GHG emissions factors,the GHG impact due to energy used by the design building
can be calculated. During the baseline one-year period, the usage of 1049.2 therm natural gas emits
approximately 5560.76 kg of eCO2 to the atmosphere, while 26,184 kg of eCO2 was let out due to
the consumption of 29,094 kWh electricity.
From an environmental aspect, GHG emissions generated by Natural gas were significantly
reduced by increasing the efficiency of the furnace. Simulation # 10 in Figure 11 seconds the
aforementioned trend and shows a 15% reduction in GHG emissions when the furnace efficiency
was increased to 95%. It is to be noted that high efficiency furnaces are now commercially
available in the market either for commercial or domestic use.
Figure 12 shows that by reducing the Lighting Power Density to 0.78965 W/ft2
for simulation 7,
the GHG emissions due to Electricity Consumption saw an 8.5% decrease annually. Similarly, by
reducing the Lighting Power Density from 1W/ft2
to 0.808 W/ft2
, 6.4% decrease in GHG emissions
from Electricity Consumption was recorded.

Increasing the exterior roof insulation did decrease the GHG emissions of Electricity and Natural
Gas. However, economically, it is predicted not to bring any significant savings to the building
owner. Calculations show that the owner will save $67/yr in simulation # 3 by using R-36
insulation on the exterior of the roof which doesn’t justify the extra cost of the insulation and the
ROR isn’t buyer feasible. Further work in this direction can be to test additional insulation in walls
(either exterior or interior) and reducing the sizes of windows along the sun facings walls.
6.0 Recommendations
1) Steel framing vs Wood Framing:
The current building was simulated with metal framing as the main load bearing element
of the commercial building. However, it is an established fact that these steel framing
elements act as thermal bridges in the walls and the roof and diminish the effectiveness of
the thermal barrier (Overbey, 2017).
According to ASHRAE, a layer of R-19 batt insulation is reduced by a staggering 63
percent to an effective R-7.1 when 2x6 metal studs are spaced at 16 inches-on-center.
Wood framing also induces thermal bridging, but it is not as bad a metal stud. Although
less conductive than steel, wood will still diminish the effective R-value of batt insulation
somewhere between 14 - 18 percent. (Overbey, 2017)
Figure 13 When used as infill in a 2x6 metal framed wall (assuming studs at 16 inches-on-
center), the effectiveness of rated R-19 batt insulation may be reduced by a staggering 63
percent. (Illustration by Daniel Overbey)
Figure 14 By comparison, when 2x6 wood studs are utilized, rated R-19 batt insulation may
only be reduced by about 16 percent. (Illustration by Daniel Overbey)
17. 16
2) Continuity in Insulation:
An important conclusion to draw here is that continuous insulation is critically important -
especially where metal framing is utilized. Continuous insulation can be achieved by
providing insulation on the exterior rather than on the interior side. Having insulation on
the exterior side enables it to have fewer thermal breaks like framing members.
3) Reduce Lightning Efficiency
As discussed above in section 5.0, although by reducing the Lighting Power density the
electricity cost, consumption and GHG emissions go down but at the natural gas cost,
consumption and GHG emissions go up. However, the benefit of this trade off exceeds the
cons as the building owners gets to save more money than he/she loses i.e. annual savings
of $322 vs annual increase of $28.
4) Increase Heating Efficiency of the Furnace.
Increasing the heating efficiency of the Furnace has no effect on the electricity cost,
consumption or GHG emissions. However, it reduces the cost of Natural Gas by $111 in
addition to reduction in Natural Gas’s consumption and GHG emissions.
