Learning Objective

At the conclusion of this course, the student will:

• Learn how to convert motor horsepower to input kilovolt-amperes for preliminary estimates.
• Learn the definition of Demand Factor and how it is used to determine power requirements.
• Learn the definition of Coincidence Factor and how it is used to determine power requirements.
• Learn the definition of Diversity Factor and how it is used to determine power requirements.
• Learn the definition of Load Factor and how it is used to determine power requirements.
• Learn recommended Demand and Load Factors for a wide variety of buildings and activities.
• Learn how to quickly estimate lighting power requirements from illumination levels for various areas.
• Learn guidelines for selection of Demand Factors.
• Learn guidelines for selection of Load Factors.
• Learn about the three types of emergency power loads.

Intended Audience

This course is intended for all of the engineers, architects and construction professionals who are members of the building and infrastructure design and construction team.  It will give non-electrical engineers an introduction to the issues the electrical engineers on the design team deal with in estimating electric power requirements for buildings, developments and activities.  And it will give electrical engineers who have limited experience with building design an introduction to electric load estimating methodology.

Benefit for Attendee

Building designers and construction professionals will gain an understanding from this course of the terminology and methods used to estimate electric power requirements for buildings and multi-building developments and activities.

Course Introduction

This is an introduction to the fundamentals of estimating electric power requirements for buildings and related infrastructure.

Paul Guyer is a registered mechanical engineer, civil engineer, fire protection engineer and architect with over 35 years experience in the design of buildings and related infrastructure.  For an additional 9 years he was a senior-level advisor to the California Legislature on infrastructure and capital outlay issues.  He has designed and supervised the design of hundreds of construction projects requiring the preparation of detailed working drawings and specifications for federal, state and local public agencies and private companies.  He is a graduate of Stanford University and has held numerous national, state and local positions with the American Society of Civil Engineers and National Society of Professional Engineers.
