In the field of public health, there is a concept referred to as the “know-do gap.” Just as it sounds, this is the gap between what we know and what we do. According to the World Health Organization, there are two aspects of this gap: one, the gap from research to policy and, two, the gap from knowledge to action. We have found that this same know-do gap exists in the built environment.
The existential threat of climate change is a prime example. We know that the frequency and severity of natural disasters will continue to increase. And we know that these events will have outsized impacts on under-resourced communities and communities of color.

Addionally, through analysis such as the National Institute of Building Science’s “Mitigation Saves” report, we know that mitigation provides significant saving over the cost of disaster recovery. The question here is how to take what we know through research and translate it into what we do on the ground in our local communities to address these complex challenges.

In our previous post we shared some of the critical lessons that we have learned over our years of designing and building high-performance houses on the ground in Hale County, as well as with our builder partners throughout the Southeast. Following are just a few of the key ways we are working to close the gap between these things that we know, and what we are doing about it.

In the Front Porch Initiative, which strives to create high-performance homes for under-resourced communities, we share our knowledge on what to build—relative to codes, universal design standards, lending and insurance requirements, and the like—and our know-how—where we show what to build—through a comprehensive set of construction documents and specifications for each of the houses.

We are currently working with a network of Field Test Partners throughout the Southeast. Through these partnerships we have learned a number of things. Mainly, it’s not only important to show what to build; we have to show how to build it, and even more importantly, why it’s built that way.

We are all familiar with the Ikea model, where we are provided a catalog of materials, a funny little tool, and a clear and comprehensive set of step-by-step instructions through which we can all become somewhat-competent furniture builders.

With our builder partners, we provide the same kind of instructional documents for the house. We know every detail about how the house is assembled:

And we also know everything about the construction sequence:

So, in addition to our construction documents, we have also developed a set of instruction documents that walk our builder partners step-by-step through both the hows and the whys of the construction of each home.

In our work, this understanding of why we build a home in a certain way is key in addressing the fundamental challenges of affordability. But while it is certainly important to ask, “What does a house cost to build?,” it is perhaps more useful to consider what a house might actually afford its residents.
In our next post, we will explore the broader impact that we might have on affordability if we can begin to consider not just what a house costs to build, but also the total cost of homeownership in the overall financial equation.
