Webinar: 100% OSA Systems With Variable Refrigerant Technology
The pandemic brought to the construction industry a deeper awareness and dialog on how best to reduce the risk of infection within the built environment. To create healthier buildings, ASHRAE, the CDC, and the EPA advocate a number of recommendations including increasing a building's outside air flow rates. Most proposed solutions, however, add to a building's operating costs at a time when our developing national imperative is moving toward carbon neutrality. Are HVAC design solutions available that allow for reducing the infection risk through ventilation while increasing operational efficiency?

Webinar: Psychrometrics Deconstructed Part 2
Просмотров 76Месяц назад
Part 1 demonstrated the psychrometric chart “is HVAC” and how the chart is a necessary “reference” tool for determining the properties of air at various conditions called “state points” and graphically illustrates the energy (enthalpy) present within given samples. Part #1 also provided term definitions for each state point; i.e. dry bulb and wet bulb temperatures, dew point, specific humidity,...
Psychrometrics Decontructed Part 1

The federal government and ASHRAE are continuing to advocate for building designs that consume less energy, provide improved thermal comfort and maintain better “Indoor Environmental Quality” (IEQ) for healthier occupants. To succeed in achieving these goals, it is essential design teams understand the properties of air and how HVAC systems play a key role in meeting these stated objectives. Th...

On March 6th 2024, the Federal Register published an article to publicly notify the U.S. Department of Energy (DOE) has reviewed and issued the determination that ANSI/ASHRAE/IES Standard 90.1-2022 will improve commercial building energy efficiency. The “DOE analysis indicates that buildings meeting Standard 90.1-2022, as compared with those meeting the previous 2019 edition, would result in a ...

Understanding Building Automation Controls can be daunting. However, with the majority of a building’s energy being taken up by HVAC, it can’t be ignored. Let us help you manage your facility better with the basics. We’ll walk through the a brief history, and then move into the basics which includes hardware, software, architecture of system, control loops. The end, you will be introduced to th...
100% Outside Air Systems - The Importance of Ventilation
Просмотров 1336 месяцев назад
The EPA, CDC and ASHRAE advocate for increasing a building's outside air (OSA) rate to reduce the risk of infection and to improve indoor air quality. ASHRAE’s recently released new standard, Standard 241-2023 Control of Infectious Aerosols, states buildings are to provide additional requirements referenced as Infection Risk Management Mode (IRMM). Requirements for IRMM are given in terms of eq...
Webinar: Quantifying the Health Impact of IAQ
Просмотров 327 месяцев назад
Our biggest exposure is the air we each inhale - an average of 2000 gallons a day of which 90% is from the indoor environment. During this obligatory process we draw into the depths of our lungs outdoor gases and particles mixed with indoor emissions from building materials, appliances, humans, pets as well as airborne microbes. It is no surprise that indoor air quality (IAQ) has a powerful inf...

Webinar - Underfloor Air Distribution Systems
Просмотров 7010 месяцев назад
Underfloor Air Systems - Principles, Design and New Technology is a one hour AIA CES HSW accredited session presented by Dan Hahne, Varitec’s Director of High Performance HVAC Solutions. As ASHRAE Standard 62.1 attests, thermally stratified environments create superior indoor air quality by drawing a single path of clean air across occupant breathing zones. Underfloor HVAC systems (UFAD) offer ...

On October 10th , 2022 the White House held its first Indoor Air Quality (IAQ) Summit and launched the Clean Air in Buildings Challenge. During the pandemic, ASHRAE’s Epidemic Task Force acknowledged “air patterns” (i.e. how air is supplied to and moves through a space) can reduce the risk of infection. Displacement ventilation (DV) and underfloor air systems are proven HVAC design strategies A...

Webinar The Physics of Airflow
Просмотров 268Год назад
During building commissioning it is not uncommon to see fans supplying less air than what the design documents call for. The most common reaction of a startup crew is to assume the fan is undersized or does not perform in compliance to fan schedules or the approved submittals. Non-compliance with design air flow is more often than not attributed to fan system effect. How air moves through a duc...
