10 Must-Have PE Exam Resources


NOTE: As per the NCEES Examinees Guide, books, notes, notebooks, etc. are no longer
permitted in the testing room. This does not diminish the importance of these Test-Prep
Resources as a method of study and preparation. For example, taking the time to
assemble a resource library will naturally help you categorize and document your
study materials, help you determine what’s essential to pass the exam, and keep all
your resources in one, easy-to-access tool.

These 10 Must-Have PE Exam Resources should be at the top of your PE Exam Test-Day Checklist

These resources are specifically listed for those taking a Civil Engineering or Mechanical Engineering Exam but some are applicable to every test. Refer to the NCEES Examinee Guide for a list of approved and not approved items allowed in the exam room. Check out the links – the pictures are links, too – to find related information.

1 – Acceptable Form of ID

Acceptable forms of ID must be government issued and must include:

  • a valid expiration date
  • your name
  • date of birth
  • a recognizable photo
  • your signature

Valid U.S. military IDs that do not include a signature will be accepted.

2 – Exam Authorization

Bring a printed copy of your exam authorization to prove that you’re registered and approved to take the exam. This will help in avoiding delays at check-in.

3 – International Building Code

We recommend purchasing a copy of the International Building Code. After the exam, you can either use it in your practice or attempt to resell it.

4 – Approved Calculator

Review the Approved Calculators List on NCEES.org.

  • Don’t try to outsmart the system on this one.
5 – Timer

A timer is a definite must-have for the test. With 80 questions on the exam and eight hours to finish, that only gives you six minutes per question. In this six minutes, you must:

  • read the question
  • determine what the question is asking for
  • find your resources
  • solve the problem
  • mark the answer sheet

For the majority of questions – hopefully – this will be plenty of time, but there is always a certain percentage of the questions that will take you more than six minutes to solve/answer. By using a timer, you can stay on schedule, picking up a few precious minutes here and there to use towards those more difficult questions. The last thing you want on test day is to be well short of finishing when the proctor indicates you have 30 minutes left.

Note: Cell phones are NOT allowed in the exam room at any time. Do not plan to use your smart phone app as your timer or else …

6 – Resource Library

In addition to the International Building Code, you need to have those resources that are specific to your particular exam. A good rule is that if you used a resource – code book, handbook, chart, graph – when solving practice problems during your preparation, then include them in your Test-Prep Resource Library©*

If you used something once or twice, make a copy of that particular resource only. Your Resource Library is not intended to be every notebook, textbook, study guide, Post-It Note®, scrap of paper you can find. You will see people hauling in so much material you might feel under-prepared.

Don’t!

There is no way they can use all that stuff in the limited amount of time available. The good news is you’ll be amused by the fact they spent a lot of time and effort getting their collection to the test site while you waltzed in carrying a box of binders.

7 – Binders of Solved Example Problems

If you’ve taken any of the Crash Courses we offer, then you are well aware of our endorsement for working example problems. You can take all the review courses you can find, read all the study guides you want, and use any number of other preparation routines, but you still won’t beat the benefit of working problems. We built our Test-Prep Resource Library©* by finding example questions for each of the topics shown for the specific exam. Working through the problems will allow you to add to the supplemental materials you found helpful. Then, assemble everything into your five-binder library. These five binders, plus a few Code books, are all you will need to pass your PE Exam.

8 – Equations, Formulas, & Conversions

Although this one seems a bit obvious, I can assure you there will be a question or two that requires some obscure equation or conversion factor you don’t have. Find a good source of equations and conversion factors – in a book or online – and add those to your library.

9 – Engineering Economics Resources

Almost all the PE Exams have an Engineering Economic analysis problem or two. During your preparation time, determine the most typical type of analysis problems – depreciation, present worth, future worth, equivalent uniform annual benefits – and find applicable tables and charts to solve these problems.

10 – Snacks and Nonalcoholic Drinks

Make certain your snacks (i.e. hard candy, candy bars, gum) and drinks can be opened and consumed with little or no noise that would disturb the other examinees. There is nothing more annoying in a testing room than someone attempting to quietly open a candy wrapper. In their efforts, they usually make considerably more noise than if they would have just opened it normally. Your goal is to quickly have a snack without anyone noticing.

That’s it … our 10 Must-Have PE Exam Resources!

Building Envelope Analysis

Building Envelope Analysis

Today’s topic is Building Envelope Analysis, but before we start …

“In life you need either inspiration or desperation.”

~ Tony Robbins

Webster’s dictionary defines INSPIRATION as “something that makes someone want to do something or that gives someone an idea about what to do or create; a force or influence that inspires someone.”

DESPERATION is defined as “a strong feeling of sadness, fear, and loss of hope.”

You are at a point in your career where you have:

  1. Been supported, encouraged, mentored, and positively influenced – INSPIRATION, or
  2. Been left to fend for yourself, learning to be an engineer on your own – DESPERATION

Although in any endeavor, there is a certain amount of learning-by-experience and trial-by-fire, the best way for someone to realize and reach their full potential is to have a mentor. Better yet, have more than one mentor who teaches, guides, and encourages.

Unfortunately, the sad truth is that most engineers who run their own business, or who ascend to a position of leadership in an already established firm, learned what they know on their own. Either they didn’t have positive, knowledgeable, and encouraging role models, or they arrogantly shunned available support and are now passing these traits on to the next generation of engineers.

However, there are alternatives.

EngineeringDesignResources.com‘s goal is to help, inform, encourage, and support those working in building design and construction. Our sole purpose and passion is to be the “something that makes someone want to do something or that gives someone an idea about what to do or create” through information, resources, and community. Take what you need from these posts, ask for help when you need it, and then, we can then pass that knowledge and INSPIRATION on to others.

BUILDING ENVELOPE ANALYSIS

As a building designer, one of your charges is to design and specify heating, ventilating, and air-conditioning systems for buildings. These systems can be as simple as ventilation fans for air movement or indoor air quality up to highly specialized air treatment systems. In addition, you may be required to provide input into the building design, especially when it comes to building materials.

Both of these functions require knowledge and mastery of Building Envelope Analysis. By learning these skills, you make yourself a valuable part of the whole Design Team. You will gain the respect of Architects, Owners, and Contractors as well as other Building Design professionals.

For your Test-Prep Resource Library©*, you want to find and include the following Building Envelope Analysis information – density, conductivity, conductance, and resistance or U-values – for:

Building Materials

Load Calculations for Building Envelope Analysis:

  • For roofs, walls, and glass conduction: q = U x area x CLTD
  • For glass solar: q = area x SC x SHGF x CLF
  • Conductivity = k in BTU per (hour)(square foot)(temperature difference)
  • Conductance = C in BTU per (hour)(square foot)(temperature difference)
  • Resistance (R) = 1/k or 1/C in (hour)(square foot)(temperature difference) per BTU
  • U-value = 1/R in BTU per (hour)(square foot)(temperature difference)
  • Available from ASHRAE or search online:
    • Cooling Load Temperature Difference (CLTD) tables
    • Shading Coefficients (SC) tables
    • Solar Heat Gain Factor (SHGF) tables
    • Cooling Load Factor (CLF) tables
  • Weather Data

NOTE: As per the NCEES Examinees Guide, books, notes, notebooks, etc. are no longer permitted in the testing room. This does not diminish the importance of a Test-Prep Resource Library© as a method of study and preparation. Taking the time to assemble your own library will naturally help you categorize and document your study materials, help you determine what’s essential to pass the exam, and keep all your resources in one easy to access tool.

In conclusion, using this Building Envelope Analysis information and a few quick calculations, you can be a driving force in the overall building design and system selections – building skin, structural, and HVAC. Set up a model on a laptop computer or tablet prior to a design meeting in order to quickly change and modify building dimensions, directions, and materials. You will assist the Design Team and Owner in making decisions, and you have made yourself a valuable part of the Project Team.

Heating and Air Conditioning Loads

Heating and Air Conditioning Loads provide the design engineer with rates of heat transfer through the building materials and surfaces – walls, floors, roofs, windows, etc. – and the contribution to the heating or air conditioning systems by various building components – people, lighting, equipment, etc. With this information solidly in hand, the engineer can proceed to design the multiple components of the building’s HVAC system.

Heating and Air Conditioning Loads

Central Plant:

  • Chillers
  • Cooling Towers
  • Boilers
  • Pumps

Air Side:

  • Air Handling Units
  • Ductwork
  • Exhaust Fans
  • Outside Air Systems
Summer Heating and Air Conditioning Loads

The peak – or highest – cooling load during the summer is that amount of heat removed to maintain the room’s design temperature. Factors that contribute to a building’s cooling load are:

  • The sun, which heats up the building exterior and then transfers into the building through walls, roofs, windows, etc.
  • Items within the building that produce heat such as people, lighting, equipment
  • The building’s geographic location
  • Maintaining the interior design temperature
Winter Heating and Air Conditioning Loads

The peak – or highest – heating load during the winter is the amount of heat added to maintain the room’s design temperature. Factors that contribute to a building’s heating load are:

  • Heat lost to the outdoors through walls, roofs, windows
  • The building’s geographic location
  • Maintaining the interior design temperature

The loads calculated for both heating and cooling are necessary to accurately size the equipment – heating and cooling systems, the air distribution systems – ductwork, diffusers, terminal boxes – and the ventilation system. A Heating and Air Conditioning Loads system that is incorrectly undersized will not be able to keep the building at the desired indoor temperature as required in the design. And a Heating and Air Conditioning Loads system that is incorrectly oversized will constantly cycle on/off and will be unable to maintain the proper humidity levels within the building. This can lead to larger problems such as equipment damage, occupant discomfort, and mold growth.

Calculating Heating and Cooling Loads

Heating and Air Conditioning Loads are mostly calculated using computer programs such as Elite Software’s CHVAC and RHVAC programs, Carrier Corporation’s HAP program and Trane’s TRACE program. These and many other programs on the market are highly specialized, can require an extreme amount of data input, produce large quantities of output, are very accurate in terms of Heating and Air Conditioning Loads, and are usually quite expensive. These programs are often necessary when it comes time to perform the actual equipment sizing, selection, and specification.

A design engineer who didn’t spend the time manipulating wall construction, roof construction, occupancies, equipment loads, and lighting configurations would not be providing the building owner with professional service. In designing the building’s HVAC systems, it is imperative to use the most realistic and accurate computer model of how the building will function in both heating and cooling environments and at different times of the day, week, month, or year.

But there are times when this accuracy and time/effort investment are not fiscally reasonable. For example, in the early stages of the design process, when the owner, architect, and engineer are meeting to determine the best course of design to pursue, it is important to understand the impact of the HVAC system on the overall design especially as it relates to space requirements. It becomes convenient to have a method by which the engineer can estimate these space requirements by quickly sizing the equipment required based on the current architectural design and extrapolating out to come up with mechanical room sizes, access into/out of and overall location within the building.

Load Calculation Worksheet

The Heating and Air Conditioning Loads Calculation Worksheet is one-page “snapshot” design tool based in Microsoft Excel utilizes psychrometric equations to solve and provide data for heating and air conditioning designs. The simplicity and unique compactness allows the design engineer to input, change, and manipulate multiple HVAC load variations, altering and adjusting on the spot, with the output immediately available on screen. The benefit to the engineer, architect and owner is in the speed of decision making. If the design team can quickly arrive at the most beneficial building design with respect to building materials, site orientation, occupancies, hours of operation, etc., this saves the overall project budget in terms of time – meetings, phone calls, design – money and frustration.

Air Handling Unit Selection Worksheet

The Air Handling Unit Selection Worksheet is designed to be used in conjunction with the Heating and Air Conditioning Loads Calculation Worksheet, although it can stand alone. The Air Handling Unit Worksheet uses parameters such as sensible load, latent load, and total load to provide the remaining variables needed to select and specify air handling units. The worksheet also allows the design engineer to input known static pressures to get a more realistic estimation of the overall Internal and Total Static Pressures for the units.

HVAC Load Calculations Worksheet

HVAC Load Calculations Worksheet

HVAC Load Calculations Worksheet specifically accelerates initial design decisions and system selection. The simplicity and unique compactness allows the design engineer to input, change, and manipulate multiple HVAC load variations on the spot, with the output immediately available on screen. The output is a one-page form showing all the pertinent data and design conditions needed to accurately select the proper heating, ventilating, and air-conditioning equipment to satisfy the space conditions.

Other HVAC Worksheets

Not only are there are many HVAC Load Calculations Worksheets on the market that are highly specialized, require an extreme amount of data input, produce large quantities of output, are very accurate in terms of HVAC loads, but they are usually quite expensive. These programs are often necessary when it comes time to perform the actual equipment sizing, selection, and specification. A design engineer who doesn’t spend the time manipulating wall construction, roof construction, occupancies, equipment loads, and lighting configurations would not be providing the building owner with professional service. It is imperative to use the most realistic and accurate computer model in designing the building’s HVAC systems. This will determine how the building will function in both heating and cooling environments and at different times of the day, week, month, or year.

Stages

However, there are times when this accuracy and time/effort investment are not fiscally reasonable. For example, in the early stages of the design process, when the owner, architect, and engineer are meeting to determine the best course of design to pursue, it is important to understand the impact of the HVAC system on the overall design especially as it relates to space requirements. It becomes convenient to have a method, such as the HVAC Load Calculations Worksheet, by which the engineer can estimate these space requirements by quickly sizing the equipment required based on the current architectural design and extrapolating out to determine mechanical room sizes, access into/out of, and overall location within the building.

At this stage of the design, the owner, architect, and engineer make preliminary decisions and select the type of system depending on the total load, the desired system control, the required space setpoints, etc. Further information and design considerations on the HVAC Load Calculations Worksheet topic are available on the HVAC Loads page.

Air Handling Unit Design Worksheet

The Air Handling Unit Design Worksheet compliments the HVAC Load Calculation Worksheet. This worksheet assists the design engineer in accelerating initial design decisions and system selection. The simple and straight forward worksheet layout allows the design engineer to input, change, and manipulate multiple AHU variations to arrive at a suitable selection. The output from the worksheet is a one-page form showing all the pertinent data and design conditions needed to accurately select the proper air handling unit equipment to satisfy the space conditions.

Air Handling Unit Design Worksheet

Other AHU Programs

There are other Air Handling Unit Design Worksheet programs on the market that require more data input, produce large quantities of output, are very specific in terms of air handling unit selection. These programs are either manufacturer specific or are very expensive. The use of these programs is often necessary and beneficial when it comes time to perform the actual equipment sizing, selection, and specification. A design engineer who doesn’t spend the time manipulating air handling unit configurations would not be providing the building owner with professional service. It is imperative to design and select the most realistic and accurate systems and equipment for the building so that the owner receives the most economical and functional building possible. However, due to budget or time constraints, there are times when the more sophisticated unit selection programs are not fiscally reasonable.

For Example

In the early stages of the design process, when the owner, architect, and engineer are meeting to determine the best course of design to pursue, it is important to understand the impact of the HVAC system equipment on the overall design especially as it relates to space requirements. It becomes convenient to have a method by which the engineer can estimate these space requirements by quickly sizing the equipment required based on the current architectural design and extrapolating out to come up with mechanical room sizes, access into/out of and overall location within the building.

It’s also at this stage of the design when the owner, architect, and engineer make preliminary decisions about the type of systems that will be used. The team can narrow down or select the types of systems, depending on the total load, the desired system control, the required space setpoints, etc. Further information and design considerations on the Air Handling Unit Design Worksheet can be found on the HVAC Load Calculation Worksheet.
