Course Catalog Description

An introduction to energy management in residential and commercial buildings, focusing on space heating and cooling, and hot water. Fundamentals of heat transfer, thermal properties of building materials, building load calculations, and energy economics. Prerequisites: MATH 160, MATH 161, or ENSP 202; and PHYS 114 or PHYS 210A or equivalent.

Learning Objectives

This course will teach you the basics of how energy is used to add or remove heat from a system. Based on these fundamentals, you will understand how our systems of heating and cooling homes affects our environment. You will gain skills in making defensible estimates of the energy use for thermal energy services like water heating and space cooling.

By the end of this course you will understand the basic physics of heat transfer and thermodynamics. With this understanding, you will be able to estimate how much energy will be used by heating processes and how much energy can be saved by new techniques. You will also be able to communicate these calculations to others. You will be able to make clear claims and support them with evidence and calculations.

To gain these abilities, you will complete exercises in computation, as well as exercises where you explain your computations. You will also practice summarizing arguments and making arguments against your own position. The assignments in this class are structured to give you practice in these skills.

Course Requirements

Your course grade will be drawn from various assignments. These include homework assignments, work in class, quizzes, exams, and outside projects. Each of these are explained in more detail below.

Homework

By completing the homework regularly, you will develop skills necessary to take a question and get estimate for the answer. You will also develop your ability to communicate and explain these estimates in writing. Your problem sets will be graded on the clarity of communication as much as the correctness of the result.

You are encouraged to work in teams and discuss the strategies and even numerical answers you are getting. You are strongly discouraged from looking at other students completed assignments. If you look at your classmates completed work, you are denying yourself the opportunity to construct the solution on you own and will prevent you from developing your skills.

Classroom Work and Quizzes

By participating in classroom work regularly, you will gain skills you need to collaborate with others on problem solving. You will take quizzes in class in groups where everyone receives the same grade. This is designed to help you collaborate and communicate your ideas so that everyone in the group agrees. You will get multiple attempts on each question. Each incorrect answer will receive a grade deduction. Someone in each group will need access to a smartphone or laptop since part of the quiz will be on Moodle. If you have an unexcused absence on the day of work, you will not receive credit for that day's assignment. Quizzes will be in class and will often be unannounced.

Project

By completing your class project, you will gain skills building a physical prototype, making predictions about its behavior, and explaining this to others. We will be building devices where we practice what we've learned in this class. You will be expected to purchase a few materials (foam, tape, wood) for this. Please see me if this creates a difficulty for you and we can look for a solution.

Class Text

There is no required text to be purchased for this class. You will read from several texts and the readings will be supplied on Moodle.

The texts we will draw from are:

You will be writing documents that contain both written text and calculations. We will be using a tool called the Jupyter Notebook since it allows you to do this. You will be expected to purchase a one-semester subscription to CoCalc where we can use these notebooks as a class.

Agreements

Excused Absences

I grant excused absences when I receive a notification before the start of class with a brief and compelling reason for the absence. You do not need to reveal any personal information in your reason. You can find a link for our absence form here.

Respectful tone in classroom

Civility is required from all students during discussions and interactions. In general, I expect students to be supportive of each others learning goals.

Willingness to take risks and experiment

I frequently try new approaches to teaching and learning. These are always with the intention of making this class as beneficial to you as possible.

Minimize electronic distractions

An important skill is self-regulation against distractions. Electronic devices are a potent source of distraction. However, we will not ban their use since they can be productive. We will frequently use Internet-connected electronic devices (phones, tablets) for learning purposes. However, using devices for social networks or other uses during class time is strongly discouraged.

University Policies

There are important University policies that you should be aware of, such as the add/drop policy; cheating and plagiarism policy, grade appeal procedures; accommodations for students with disabilities and the diversity vision statement.
