Capillary Action – Why You Always Need a Gap at the Bottom One common mistake I see all the time is builders not leaving a minimum ⅜" gap where wood or cladding meets the ground or concrete. It might look tighter and more finished when it's flush, but it’s a problem waiting to happen. Here’s why: When wood is placed directly against concrete or the ground, capillary action can pull moisture up into the material — even when there's no visible water. The surface tension of water can actually cause it to "climb" up to 9.8 mm, according to the BC Building Code. This constant exposure to moisture can cause rot, swelling, or even mold, especially if there's no drainage or ventilation. It's something I see way too often — particularly at the base of garage door trim, where water gets wicked up from the driveway or slab. So always leave that gap. It’s a small detail that goes a long way in protecting your materials and making your build last. #BuildingScience#CapillaryAction#DurableDesign#MoistureManagement#HighPerformanceBuilding#ConstructionDetails#FutureProofHomes#SustainableConstruction#BuildingEnvelope#SmartBuildingSolutions#NZBuilders#BetterBuilding#EnergyEfficientHomes#BuildingTips#WestCoastBuilding

Mechanical Rooms – Smart Automation & Advanced HRV System This mechanical room is a great example of how smart automation and efficient design work together in a high-performance home. One of the key components in this setup is the HRV (Heat Recovery Ventilation) system, and at NZ Builders, we strongly advocate for using the Zehnder HRV system — and there are several good reasons for that. Yes, it comes with about a $5,000 upcharge (2020), but the benefits more than justify the cost: Flexible, space-saving tubing: Zehnder uses small-diameter tubes that we can easily run through steel structures, LVLs, and tight framing — all without the need for bulky ductwork or bulkheads. Since building bulkheads adds cost and complexity, this makes the price difference a wash in the end. Ultra-quiet operation: These systems run two fans — one for supply and one for exhaust — which makes them super quiet and allows us to perfectly balance airflow throughout the home. Humidity control: A balanced HRV system helps regulate the humidity levels in the home, creating a more comfortable and healthier indoor environment. Optional AC integration: You can run air conditioning through the supply side of these tubes if desired, adding another layer of climate control without extra ductwork. Smart range hood bypass: You can even connect your range hood to the HRV system. When the range hood kicks on, the HRV will activate a bypass mode — which helps by not putting your home in a negative pressure situation. Here’s something critical to understand: If your home has leaky windows or poorly sealed areas, and your home is running in a negative pressure state, it can actually pull water through those small gaps. In fact, even a single nail hole can allow up to 2 litres of water per hour to be drawn into the home during rain. That’s huge and will turn your home into a compost. So while these systems offer many benefits — better air quality, humidity control, quiet operation, low maintenance — you also need to build with airtightness in mind to truly take advantage of everything they offer. #HighPerformanceHomes#MechanicalRoom#HRVSystem#ZehnderHRV#SmartHomeAutomation#EnergyEfficiency#HealthyHomes#HumidityControl#QuietComfort#AirtightConstruction#SustainableLiving#IndoorAirQuality#FutureProofHomes#BuildingScience#EfficientDesign

Domestic Hot Water Recirculation Pumps – Why We Recommend Them One feature we highly recommend in our homes is a recirculation pump for domestic hot water. It’s a simple system that brings a big boost in both comfort and efficiency. Here’s how it works: We run a dedicated loop from the hot water tank, around the house and close as possible to your hot water fixture, and back again. The recirculation pump continuously moves hot water through that loop. So when you turn on a hot water tap — whether it’s in a bathroom, kitchen, or laundry — you get instant hot water, without waiting for it to travel from the tank. A lot of people hesitate because they think: "Well, I have to buy the pump, install it, and it’s something else to maintain." But in reality, these pumps: Use very low energy (typically just a few watts). Are extremely reliable and can last a very long time when running continuously. Save you money in the long run. Here’s why: If you don’t have a recirculation loop, every time you run a tap, you’re dumping cold water down the drain while you wait. That cold water then enters your hot water tank, and you pay to reheat all of it. So in most cases, the energy and water savings from the recirculation system more than offset its operating cost — and you gain the luxury of instant hot water at every fixture. #HotWaterOnDemand#RecirculationPump#EfficientHomes#InstantHotWater#HighPerformanceLiving#SustainableHomes#EnergyEfficiency#WaterConservation#HomeComfort#FutureProofHomes#SmartBuildingSolutions#LuxuryLiving#BuildingScience#EfficientDesign#NZBuilders

Covering Bracing Holes in Concrete Insulated Panels You might be wondering why these bolts and washers are here on the face of the panel — and here’s the reason: These are used to fill in holes that were originally for temporary bracing during construction. When we’re building with concrete insulated panels, the wall panels don’t stand up by themselves. So during installation, we use temporary braces to keep the panels plumb and stable until the roof is tied on or the concrete slab is poured. Once the bracing is no longer needed, we're left with a threaded insert in the panel. If the panel is not being painted. Rather than leaving it exposed, we often use a washer and bolt to cleanly cover the hole and give it a finished look. This is just one of several ways to deal with leftover brace holes — and it works particularly well in builds with an industrial or minimalist aesthetic. #ConcreteInsulatedPanels#HighPerformanceBuilding#ModernConstruction#BuildingScience#IndustrialDesign#MinimalistAesthetic#SustainableBuilding#ConstructionDetails#EnergyEfficientHomes#FutureProofHomes#DurableDesign#SmartBuildingSolutions#PanelizedConstruction#ConcreteHome#NZBuilders
