Does data in construction really matter?

“I almost don’t want to know”That’s Hamish after Cameron Munro walks us through what a few cheap sensors can tell you about your home. We’re talking about data in construction with Cam today: what’s worth measuring, what isn’t, and what to do with the numbers once you’ve got them. If you’re a builder, designer or homeowner who’s curious about moisture in your walls and roof, or the air you’re breathing at home, start here.Cameron’s first rule is to work out what you want to know before you buy a sensor. Matt shares the sensors he’s put in his own roof, and Cameron shows us the easiest comfort test going: a temperature sensor in a ping-pong ball sprayed matte black, which shows how cold the walls and windows really are. We also get into the treated pine batten debate, what the roof cavity numbers do and don’t prove, and why Cameron is careful about the word “proof”.Then we cover the three things you can monitor: comfort, air quality and energy use. Cameron explains why a meter on your heat pump doesn’t tell you how much heat you’re getting, why a carbon monoxide alarm is a must if you burn anything at home, and why he reckons PM2.5 matters more than CO2. We also talk about wood fires, frying dumplings and why Matt wishes he’d ducted his range hood outside.We finish with the sensors worth buying and what we still need to test. They now cost under $100, and you’re better off with a good app and history than lab-grade accuracy. Cameron also tells us what he’d like to see monitored next, like what’s going on inside wall and roof build-ups where you can’t see.CHAPTER MARKERS00:00 Introduction02:24 Smart Membrane Sensors04:07 What Should We Monitor05:22 Black Bulb Thermal Comfort13:11 Do We Need Treated Pine Battens15:15 Roof And Wall Cavity Moisture18:55 Heat Pumps And COP22:00 Carbon Monoxide Alarms25:12 CO2 Levels And Sensor Limits31:54 PM2.5 Measure What Matters39:26 Cooking Fumes And Range Hoods41:27 Cheap Sensors Worth Buying45:43 Benchmarking Buildings46:43 What We Need To Test NextConnect with Cam: https://passiveanalytics.com.au/Our Sponsors:Pro Clima - https://mindful-builder.captivate.fm/proclimaWunderbuild - https://www.wunderbuild.com/Biz Tech Guru: https://www.biztechguru.com.au/Connect with us on Instagram: @themindfulbuilderpodConnect with Hamish:Instagram: @sanctumhomesWebsite: https://www.yoursanctum.com.au/Connect with Matt:Instagram: @carlandconstructionsWebsite: https://www.carlandconstructions.com/
