PTAC Unit Myth 3 of 3 - Dehumidification

This is a 3 part Vlog series of, “The 3 Myths of PTAC Units.”

Over the past 30 years, building experts at Liberty Building Forensics Group (LBFG) have investigated hundreds of moisture problems (involving thousands of guest rooms) and in the process, have observed three repetitive assumptions that appear to be completely ignored by the building industry:

  1. PTAC units cannot effectively ventilate interior spaces.

  2. PTAC units cannot effectively pressurize hotel guest rooms.

  3. PTAC units are often ineffective in dehumidifying hotel guest rooms, especially when outside conditions are hot and humid.

The 3 Myths of PTAC Units

Even though there is strong evidence that PTAC units cannot consistently provide these stated (or implied) features, the astonishing truth is that the entire hotel industry (including owners, operators, developers, contractors, and designers) seems to believe that they can.

Campus Community Management Firms, Beware!

Before too long, they were faced with a property management company’s worst nightmare: the entire complex had to undergo a $50M+ reconstruction after significant water intrusion was found to have deteriorated the building structure and after moisture and humidity from the HVAC/plumbing systems had resulted in large-scale hidden damage that included mold.

The Hidden Risks Of Green Buildings: Avoiding Moisture & Mold Problems

Some experts have described the green building movement as “the #1 mega-trend that will change the rules of global business.”

The great irony of building green in the Southeast is that the very concepts that are intended to enhance a building’s performance over its entire lifetime are many of the same practices that make a building highly susceptible to catastrophic moisture and mold problems during its first few summers of operation.

While LEED-certified buildings have many positive benefits, there is strong evidence to suggest a direct correlation between new products/innovative design and building failures — especially in Florida’s humid climate. Simply put, departing from the “tried and true” often means increasing the risk of building failure.

This article presents “must-know information” if you’re considering green buildings!

Mold and Moisture Prevention

Published by NCARB

“An alarming number of buildings suffer from moisture and mold problems. No single document can address all the issues related to moisture intrusion and mold growth. However, we believe this monograph addresses a significant proportion of the problems that architects will encounter in the design and construction of a typical commercial building.”

— J. David Odom, as quoted on NCARB.org

Features:

  • This manual looks at the key issues that can help owners, designers, and contractors work together to improve decision-making. Design professionals will discover what they need to do in order to develop good building performance.

  • The end of the schematic design and design development chapters have sections outlining documents, steps, and criteria that should be completed before the next phase in the process is begun.

  • The final design chapter has a peer review section that includes a checklist to provide designers and builders with independent design reviews and technical guidance to promote technically sound, budget-conscious designs.
