Have you ever thought about the relationship between velocity and pressure? If you think about a fluid being forced through a small orifice, you can fairly easily picture the fluid speeding up as it goes through the orifice. However, did you also know that the surrounding static pressure DECREASES at the point of high velocity? […]

I know I’m not the only one who has sometimes felt a little bad doing heat maintenance.

 Nikki Krueger and Genry Garcia return to the podcast to talk about a recent IAQ & dehumidification case study on a vintage home in Miami. The home was very clean but had a musty odor and VOC concerns. You can read the case study in the “Literature” section at https://www.santa-fe-products.com/about-us/media-resources/. Blower door tests and ZPD […]

 Genry Garcia joins the podcast to give an intro to ASHRAE Standard 62.2. He and Bryan also share a nice rant about accountability in HVAC design. Standard 62.2 is the ventilation standard for low-rise residential buildings, which dilutes airborne contaminants like VOCs and CO2. Before coming up with a ventilation strategy, we need to […]

Genry Garcia returns to the podcast to talk about blower doors and why ACH50 may needlessly complicate efforts to tighten a building envelope. A large element of indoor comfort comes down to controlling the load, especially the latent load. Even though we can control indoor humidity sources, we may also deal with infiltration, which contributes […]
