A clean air conveyance system is a benchmark for good indoor air quality (IAQ). But how do you know when you need duct cleaning? After all the ductwork in a facility is out of sight and typically out of mind. Unless you periodically take a look inside of the ducts you would never know […]
The Q-Pac HVAC fan retrofit is a viable energy savings upgrade for AHU restoration. Energy efficiency and sustainability are hot topics for building owners and facility managers. More than not these facility stake holders work closely with energy services consultants and engineers to map out plans for bigger savings and returns on investment. It is […]
A multi-approach remediation plan was successfully completed to restore the university campus building* after mycotoxin proliferation. Background Part 1 of this 2 part series explained the likely cause of the chemical byproduct of mold and its spread into different areas of the building. It also demonstrated how the Building Sciences and EDLab divisions of Pure […]
Steam Coil Cleaning Saves Energy: A Case Study Originally published as a case for Pure Air Control Services and reprinted in the Spring 2017 Issue of HVAC/P Magazine. The Project: Georgia Tech University, founded in 1885, covers over 400 acres and has 275 buildings with 9 million square feet which are occupied by over 25,000 […]
5 questions to ask in the duct cleaning specs before awarding a contract. Lowest price versus best value age old conundrum in facilities purchasing. This is especially true and complicated with professional services. Going with the cheapest solution often realizes short term savings. However, it can cost exponentially more in the long run when the […]
Buildings are havens for asthma and allergy triggers. This article will take a look at how to identify and minimize their impact to occupants. Everybody knows how outdoor air affects seasonal allergies. But what about indoor air quality? Even with the most rigorous housekeeping allergy triggers still thrive indoors. Asthma and allergies affect more than […]
Breathing dust or water droplets containing contaminated bird droppings can lead to several diseases, including a pulmonary disease called Cryptococcosis. Birds affect HVAC systems and equipment in many ways. Some ways are obvious. Others? Not so much. Let’s take a look at how birds affect HVAC systems from a mechanical and building health standpoint. HVAC […]
Commercial and especially institutional properties across the United State have to maintain aging infrastructure on a daily basis. One of the most critical components to a building’s health, occupant comfort and energy efficiency is the heating, ventilation and air conditioning (HVAC) systems, in particular air handling units (AHU) found on rooftops and in mechanical rooms. […]
HVAC Preventative Maintenance vs. Deferred Maintenance We are a culture of clichés. A cliché is defined as “a phrase or opinion that is overused and betrays a lack of original thought”. In other words, a stereotype. Consider then, the notion that “Deferred Maintenance” saves money or allows for current operational funds to be used immediately […]
The PURE-Decon/Halosil disinfection system dispenses a dry fog of atomized HaloMist™ into the air. The mist fills the room and is drawn into areas that conventional topical cleaning and disinfection can’t reach. This technology kills drug resistant bacteria, such as methicillin resistant staphylococcus (MRSA), and Clostridium difficile (C-diff), as well as pathogenic bacteria, viruses (like […]
