What is HVAC Design?
Heating, Ventilation, and Air Conditioning Design is both an art and a science requiring experience and training in the field of heating, ventilating, and air conditioning. Additionally, an appreciation for architectural design is inherently important in solving HVAC system design situations. An understanding of occupant comfort and client requests for system control is also significant.
HVAC Design Fundamentals 1
HVAC Design contains elements of architectural appreciation. It is the engineer’s responsibility to provide designs that coordinate with or enhance what the architect is trying to convey in the building design. The design is usually what the client is requesting. Therefore, don’t be guilty of adding elements to the building that detract from the functionality or visual appeal of the interior or exterior. We are most successful when our designs are completely covert for the average person or are intentionally organic in the overall design.

The “Art”
Accomplish the art of HVAC Design through:
- an understanding of the client’s needs
- the building occupant’s temperaments
- knowing how different buildings react to changing climatic conditions and different geographic locations
Mastery of this art comes with time, experience, and a deep-seated desire to provide the best possible solution. The more projects a design engineer can engage in, the quicker he or she develops a sixth sense that allows for intuitive design decisions.

If you are a recent graduate or are new to this field, you can help yourself immensely by studying other designs, getting input from a senior engineer who can act as your mentor, and from visiting this and similar sites. The intent here at EngineeringDesignResources.com is to provide the design engineer with the right tools to be successful in their career.

The “Science”
Accomplish the science of HVAC Design using proven formulas, equations, software programs, rules-of-thumb, or short-cuts. There are specific answers to specific design situations. No matter where a building is built, if all the variables are the same, the heating, ventilating and air-conditioning systems will be the same – because the inputs into the equations will be the same. Variables include:
- construction materials
- occupant load
- internal heat-producing equipment
- geographic considerations such as latitude, longitude, and elevation

HVAC Load Calculation Worksheet
The HVAC Load Calculation Worksheet specifically accelerates initial design decisions and system selection. The simplicity and unique compactness allows the design engineer to input, change, and manipulate multiple HVAC load variations, which can be altered and adjusted, in real time, with output immediately available on the screen. The return on investment for this worksheet is hours and hours of time savings! In addition, you and your firm will realize a greater efficiency in the design process, along with gaining the client’s respect for providing the best possible solution to their HVAC project.

Air Handling Unit Selection Worksheet
The Air Handling Unit Selection Worksheet is designed to use simultaneously, and in conjunction, with the HVAC Load Calculation Worksheet. However, it can stand alone if you know the conditions you are attempting to satisfy.
The Air Handling Unit Selection Worksheet uses parameters such as sensible load, latent load, and total load to provide the remaining variables to select and specify air handling units. Use this for small, single zone fan coil units, as well as split systems up to large, industrial-type air conditioning systems. The worksheet also has a section for estimating internal, external, and total static pressure in order to perform fan selections.
By using the Air Handling Unit Selection Worksheet and the HVAC Load Calculation Worksheet, you will realize significant increases in overall project profitability, project delivery times, and improve accuracy in scheduling of air handling equipment.
