How to Design and Install Kitchen Exhaust and Make Up Air Ventilation (Case Study)

Corbett Lunsford

Another installment in a series with Healthy Indoors Magazine (http://HealthyIndoors.com) follows the real-life, gritty planning and installation of the make up air system in a 1950's ranch over a crawlspace. The goal here is to install effective ventilation for the kitchen range with an exhaust hood AND make up air that will hopefully be the path of least resistance. We're using a Broan exhaust hood paired with an Aprilaire KV make up air damper, or an 8144NC (in an experimental application, as explained in the video). This house is not airtight by any means, and some might think make up air is overkill in an older home, but obviously we disagree enough to suffer through this.

High Performance Crawlspace Walls

Corbett Lunsford

Corbett, Grace, and their crew of awesome nerds pour a high performance crawlspace foundation wall and totally skip the slump test, on purpose, which they know will get a lot of loving kindness in the comments section.

Geotechnical Engineering for Foundation Footings: Dirt Performance and 4-in-1 Form-A-Drain

Corbett Lunsford

Corbett hired Geoff Hebner of Padstone Geotechnical Engineering to ensure the house being built will stand for a hundred years or more.

In part 2, Corbett shows the grading and leveling process with 6-8" lifts and 4x compaction using a remote-controlled trench roller.

In Part 3, Geoff returns to run a simple geotechnical test on the compacted dirt before pouring concrete, and Corbett finds out he's not as slick as he hopes.

FINALLY, we get to pour the concrete once the footings are finished with rebar, and well-supported per Geoff’s geotech engineering specs.
