Awesome Robert Cialdini interview about reducing energy consumption using behavioral change. I think our program (NJHPwES) is pretty good. But unfortunately it neglects the behavioral side. Cialdini argues that this is the most cost-effective way to reduce energy consumption. Never mind what people believe — how can we change what they do? A chat with Robert Cialdini When it comes […]

Great article from Martin Holladay on GBA
Energy guru Marc Rosenbaum posts in comments. Heat pump water heaters are interesting. We're currently sub-metering hot water consumption on a couple of homes. The goals are to project savings from switching to heat pump water heaters from oil or electric resistance, and if worthwhile, appropriately size the heat pump water heater based upon current usage. This type of analysis […]

Just received the latest JLC, which is one of my favorite construction magazines. From their article, "Energy-Efficient Modular": "We didn't really save much money by building modular, because it's the finishes … that tend to drive up costs." Ahh, the siren song of profitable prefab housing. Here's my thesis. The post WWII housing boom led to incredibly efficient building techniques. […]

Custom Shelving
These shelves were designed to house books and items while maintaining the apartment’s contemporary feel. The client wanted the shelves to appear as though they traveled throughout the apartment, rather than featuring themselves neatly in one plane. The added third dimension provided by having the cabinets turn against the right-hand wall and sweep away up high presented interesting detail challenges, […]

Replacing Windows while Insulating the Wall Assembly
This video shows our method of installing replacement windows in the new-construction style while increasing the insulation levels in the wall and taking care of a few other technical problems. One benefit of the system is that you can pause for as long as you like between installing the window and insulating/re-siding the walls. This opportunity arises through the installation of […]

Improving buildings in the real world
There is an incredible wealth of information on how to construct energy efficient, durable, and comfortable buildings. Sure, most of that information is totally disregarded when buildings are constructed. But it would be difficult to argue that houses in the US are constructed poorly because technicians don’t have access to good information. This wealth of information should be directly applied […]

Home Performance and Hard Choices
I spend a lot of time reading about carpentry, building science, and construction. One of my hopes for this blog is to help others apply good building science under a multitude of real-world constraints. Common constraints include: Budget, Owner’s expectation that they won’t be in the house for long, Contradictory assertions from everyone and their brother who works on houses, […]
Larry Haun RIP
Fine Homebuilding has this obituary for Larry Haun. An icon of carpentry, I was inspired to switch to gang-cutting rafters by watching his videos and reading his books. One of the building construction greats.
