TDP-701 System Selection
System selection can be a simpler, more understandable process if the designer and owner follow a step-by-step procedure. This TDP on System Selection presents one method that can be used by designers on most commercial projects. An example project will begin by assembling and documenting all available project data at the earlier phases of the design process. After determining the delivery method, budgets and schedules, and running rough heating and cooling loads for a zoned project, an initial list of potential HVAC systems will be assembled. This list will be reviewed against various design criteria that were determined for the project. The final two or three HVAC systems will be evaluated against a prioritized list of design criteria using a rating method called the Systems Scoresheet. The system with the highest numerical rating, once approved, will then be designed and built. Throughout the selection and design processes, job requirements and system parameters are documented on the Design Record form presented in the TDP.

TDP-702 Comfort Control Principles
Air-conditioning systems maintain the desired indoor comfort level, starting with space temperature. Other comfort parameters include maintaining acceptable room humidity, air motion, air quality, and air purity. The relative importance of each system function depends upon the specific project and application. Zoning is required to maximize the number of spaces that are successfully conditioned to the design criteria. There are many different types of HVAC systems, and many more elements that can be used to achieve the heating and cooling capacity, provide ventilation, maintain humidity, distribute the air within the spaces, etc. This module will discuss various temperature control strategies and HVAC systems that can be employed to maximize comfort provided to the building occupants.

TDP-704 Variable Volume and Temperature Systems
VVT is an economical, all-air zoned system that is ideal for many commercial jobs, especially at a time when there is so much design emphasis being placed on high-quality air treatment, outdoor air ventilation, and room air circulation. VVT systems are a popular solution for heating and cooling multiple zone applications in small to medium size buildings. VVT controls typically are supplied pre-packaged from the HVAC equipment supplier and are ready to install by the mechanical contractor. The objective of this module is to define VVT and describe how it achieves zone temperature control.

TDP-706 Water Source Heat Pumps
This module will provide an understanding of the components in water source heat pump systems, configuration options, system benefits, and many applications associated with the overall system. WSHP systems have become a very popular choice for use in commercial buildings where individual zones of control are required to maintain comfort conditions. Building types that exhibit a simultaneous cooling and heating load are ideal candidates. WSHP systems have other desirable characteristics like zoning capability, ease of design, and reliability so that buildings where little or no reclaim will take place are often still considered for using a WSHP system.
