What is commonly referred to as the building envelope is reviewed in this course. The building envelope includes infiltration, insulation, windows, and vapor barriers. HVAC are reviewed including HVAC terminology, types of HVAC systems, thermostats, energy recovery ventilators, and methods to improve the efficiency of HVAC systems.
Lighting is reviewed including lighting terminology, types of lighting systems, methods to use lighting efficiently, and lighting controls.
Building equipment is also reviewed including water heaters, air compressors, electronic equipment, and appliances.
After taking this course you should,
This course is intended for electrical engineers, mechanical engineers, architects and others who want to know more how to save energy in residential and commercial buildings.
Benefit to Attendees
From this course, the reader will learn a few of the simple and effective methods to improve energy efficiency in residential and small commercial buildings.
Rising energy costs have created a renewed interest by facilities managers in the energy efficiency of their facilities. Whether it is a commercial building, an industrial plant, or even an individual residence, there are strategies that can improve the efficiency of the facility without reducing its comfort or operational effectiveness.
Space heating is the largest consumer of energy at 49% of the total usage in a home, followed by lighting and appliances, which is 23% of the total. Water heating is the third largest consumer of energy at 16% of the total. These values vary based on the area of the country with air conditioning making up a larger percentage in the South and Southwest parts of the United States. Small commercial buildings will have similar usage patterns except that the water heating will be less and the air conditioning and lighting will be a larger percentage.
Strategies to improve the energy efficiency of facilities include, improving the building envelope, installing energy efficient heating, ventilation, and air-conditioning systems, using appropriate lighting, and managing the various appliances commonly found in commercial and residential buildings.

With rising energy costs it is important for energy managers to consider many different approaches to reducing energy consumption. The preceding material has been an overview of topics related to energy consumption in residential and small commercial buildings. Some of the most significant energy efficiency improvements are most easily made during the construction phase of a facility such as building envelope improvements and HVAC choices. Other decisions, such as lighting changes, equipment purchases, and operating procedures can be implemented relatively easily at anytime. The United States is entering a prolonged period of increasing fuel costs and all viable energy conservation measures should be considered.
