House in a House.

There is a significant amount of existing domestic housing stock in the United States that is ready to be insulated and retrofitted for improved energy performance. These existing houses can be upgraded to be more climate responsive extending their efficient occupancy for many decades to come. Instead of replacing or demolishing existing dwellings, they should be retrofitted so the environment is not burdened with inefficient houses. This concept limits the deterioration of neighborhoods, landfills are not overwhelmed with waste, and ultimately reduces greenhouse gas emissions. This paper is a case study that demonstrates the strategies incorporated to make a dwelling more climate responsive. The upgrade includes a rainscreen in conjunction with a crisscrossing lattice system mounted on a sub-façade, plus the addition of an interconnected passive ventilation system at the roof ridge. This paper examines the techniques utilized to install the rainscreen and how this system mitigates heat gain from solar radiation on the sub-façade, roof, and insulation. The idea is to construct and live in a house in a house. [ABSTRACT FROM AUTHOR]
