HVAC - Natural Ventilation Principles and Practices, 4 PDH
Course No. M04-038
an open facility that contains 6 natural ventilation systems
Natural ventilation is not just about providing multiple operable windows in a building. This course outlines the basic principles underlying natural ventilation and explains how best to proceed with a specific design. It is aimed to assist designers to establish how their building may be naturally ventilated.
Detection for Traffic Signal Controllers, 2 PDH
Course No. C02-057
an electric traffic signal controller machine that is boxed
This traffic signal operations course presents information regarding vehicle and pedestrian detection systems used in modern traffic signal control. The material is intended to provide engineers with a practical overview of detection types, components and operational characteristics.
Foreign Voltages and Frequencies Guide, 3 PDH
Course No. E03-022
a black power cord next to a white outlet
This course introduces the issues associated with designing low and medium voltage electrical systems using components whose voltage and frequency requirements are outside the system's operating voltage and frequency. This occurs when designing such components for the US market abroad.
Preventing Wrong-Way Driving on Freeways, 6 PDH
Course No. C06-013
a freeway that is highly populated with traffic
Driving the wrong way on freeways has been a traffic safety problem since the 1950s. This course identifies the contributing factors to wrong-way crashes on freeways and develops promising, cost-conscious countermeasures to reduce these driving errors and their related crashes.
Intro to Water Supply Systems Operation & Maintenance, 5 PDH
Course No. C05-018
a water supply system next to the water at sunset
This course provides an introduction to maintenance inspections and general maintenance services required for domestic water supply systems. It presents information about tools and equipment, lubricants, and materials and supplies required to perform general and specific equipment maintenance tasks.
Freeze-Thaw Resistance of Concrete, 3 PDH
Course No. C03-044
attached concrete pillars
The air content of concrete is a factor in the concrete’s durability. This course addresses the behavior of concrete with “marginal” air void systems, in which the air content and other air void system parameters do not consistently meet commonly accepted thresholds for freeze-thaw durability.
Intro to Trickling Filter Wastewater Treatment Plant, 2 PDH
Course No. C02-055
a metallic wastewater treatment plant
This course provides an introduction to trickling filter wastewater treatment plants. It explains how their recent design has contributed to their low initial cost, low operation and maintenance costs, relative simplicity of operation, and comparable performance to that of activated sludge plants.
