VAV System Design Considerations

A mechanical engineer must consider several variables and equipment types when designing a VAV system.  This includes the load on the space, the static pressure in the ductwork, the types of terminal units, and the occupancies in the space.  The engineer must also consider how the terminal units are going to be controlled.  These decisions must weigh the initial cost with the long-term energy efficiency. Using a theoretical office building, we will walk through the general design process and the decisions the engineer must work through to arrive at a final design. Design Process When an architect is designing a building, for purposes of this exercise an office building, they’ll start with a core and shell.  The information they’ll provide the engineer will include:… Read more

VAV System Components

Occupant comfort is critical for the building owner’s return on investment.  Chilled Water VAV systems have proven to deliver the highest level of occupant comfort, including thermal and acoustical satisfaction.  Delivering comfort requires the cooperation of several pieces of equipment. When set up and controlled properly occupant satisfaction can be optimized along with the energy consumption.  A major study, ASHRAE RP-1515, proved that optimizing occupant comfort coincides with a more efficient use of energy for several buildings. Understanding how the HVAC components of a VAV system work together to maintain comfort, paired with optimal set points will deliver a better system to your customer. System Components The equipment that work together to deliver occupant… Read more

VAV Systems Deliver Comfort

When designing a commercial HVAC system that will serve a diversity of spaces, selecting a VAV air side system has proven to be the best choice. A mechanical engineer has two goals for their future occupants, deliver optimal comfort at the lowest possible energy usage; in that order.  When compared to other options, the VAV System wins on both fronts. Comfort equals Profits Fundamentally, the goal of an office real estate developer is to construct a building who’s financing and operational costs will be less than the rent the building will provide.  The developer hopes the building will attract and retain occupants by providing the best comfort, location, design, and amenities possible with the construction budget. They’ll also have an eye towards energy efficiency to reduce the… Read more

Rest Easy with Nailor Stealth Terminal Units

Imitated but Never Duplicated Building engineers, owners, and occupants can rest easy knowing their Nailor Fan Powered Terminal Units provide the best combination of sound, control, and comfort.For over 20 years Nailor has led the industry with the most innovative solutions for VAV systems. The Stealth Design has now been validated as the benchmark and industry is rushing to imitate the design. #flattered Fan Powered System Selection When designing a VAV system there are two choices for the fan powered terminal units that condition the exterior of the building; Series and Parallel. A recent study highlighted in the ASHRAE Journal showed that compared to a PSC motor baseline, choosing a variable speed controlled ECM series fan powered terminal unit can reduce a building HVAC energy usage… Read more

Nailor Position on COVID-19 & Air Cleaning

Date: December 31, 2020 (revised) There have been multiple papers written by many authorities on Covid-19 and the necessity to clean the air in buildings. Our opinion is that four of the best sources are The Center for Disease Control (CDC), The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) World Health Organization (WHO) and Taylor Engineering’s White Paper. The opinions in this paper are our best assumptions as garnered from those and other sources about the virus. It covers where the virus comes from, where the virus is located in an infected room, the equipment we manufacture, and what is the best action to take to best prevent infections within your building. Where does the Virus Come From? All the papers we have read suggest that the virus does… Read more
