HVAC System Efficiency by Terminology
If you’re a contractor, engineer, or a manufacturer or sales rep for HVAC components, you know not all HVAC systems are created equal. However, the
people who need to purchase components or have them installed may not be as well-versed.
Throwing concepts at them such as EER, SEER, and HSPF is one way to explain what they stand to gain or lose with various levels of HVAC efficiency. Only, these terms might sound like Greek to the layperson. So, here are some pointers on how to explain these efficiency metrics….
ASHRAE Standard 241: Greater Healthy Indoor Air Demands on Schools
Do the school buildings you lead, manage, contract for, maintain, or sell HVAC equipment to meet ASHRAE Standard 62.1 for Ventilation and Acceptable Indoor Air Quality? If not, that building is already a health and well-being threat to students and faculty. As if those in charge did not already have work to do to achieve healthy air exchange, ASHRAE’s newest Standard–241–is here to up the ante in preparation for the next pandemic or public health emergency. Not worried about that just yet?
Taking the Breach of the 1.5°C Threshold For a Spin in 2024
Rarely, do we get a glimpse into the future. Sometimes, that’s a good thing, but for certain circumstances, who wouldn’t welcome the chance to discover misfortune heading our way so we can prepare for it? Then there’s the question of would we do anything about it, if...
Innovation in Energy Recovery: The BPE-SC-UNI-4000
This unitary, galvanized steel unit sporting integral fans, filters, intake louver, and control box is built from two BPE-SC-UNI-2000s. It handles air exchanges from 1,000 to 4,000 cfm. Specifically sized for commercial and industrial-dedicated ventilation...
Holy Smokes! The Time to Tackle Building Stock Emissions is … Yesterday.
One of our goals at BPE is to encourage building and HVAC contractors to relay the importance of building or retrofitting residential, commercial, and industrial building stock with the climate crisis in mind. Unfortunately, many people aren’t too quick to worry about things they cannot see for themselves and/or feel they can’t do anything about–such as a slowly warming planet. But you know where that gets us, right?
Field Assembly of BPE SC-UNI-2000 and 3000 DOAS Systems.
The Upper Fan has a Louver and fan box in front of it that is normally attached. This photograph is to show the fan module before the louver is added. The DOAS (Dedicated Outdoor Air System ) is shipped with the fan modules removed and packed around the ERM (Energy Recovery Module) as shown:
Custom DOAS systems are more important now than ever!
Why include custom dedicated outdoor air system (DOAS) plans in your new construction or retrofit project? Because you’ll lessen health, financial, and climate issues in indoor spaces that may have felt like mere annoyances in the past. Collectively, we have a lot more riding on indoor air quality and energy efficiency these days—not to mention the growing climate threats of years ahead.
Applying Energy Recovery Ventilation: Latent Only Application – Minimum Best Practices
Latent only cooling is a method of utilizing the cooling energy of air leaving an existing or new construction fan coil air handler, to simultaneously pre-cool the air entering the air handler and reheat the air leaving the cooling coil. Installations and field tests have shown this can take an average fan coil either dx or chilled water and render the unit up to over 95% latent with very little temperature change.
Gas Stove Dilemmas
Still hanging on to that gas stove? You rebel you! But should you? Well, that depends on a some questions and considerations we have for you.
Efficiency and Flexibility in ERV System Layouts
An ERV product line should accommodate the simplest to the most unique HVAC design needs–and efficiency should not suffer for it. Here’s a look at the heart of a high-efficiency commercial/industrial ERV followed by a variety of system layouts and duct sizing tips.
