We here at the Green Cocoon have a passion for efficiency, not only in our daily operations but also in the projects that we choose to work on. We have been fortunate enough to work on everything from small renovations and existing attics to energy positive, net-zero and our favorite, the Passive House. What is a passive house, you ask? The term passive house (Passivhaus in German) refers to a rigorous, voluntary standard for energy efficiency in a building, reducing its ecological footprint. A continuous, balanced supply of fresh air ensures unparalleled indoor air quality. Operable windows connect indoors with out. Super-insulated walls hold warmth in the winter and cool in the summer. Special windows and a building envelope consisting of a highly insulated roof and floor slab as well as highly insulated exterior walls keep the desired warmth in the house – or undesirable heat out. It results in ultra-low energy buildings that require little energy for space heating or cooling.
Currently in the U.S. there are less than 100 certified passive houses in existence, and we have worked on 4 of them. In the fall we will be starting another passive house in Rhode Island. We like to think of ourselves as the “go-to insulation company” for highly energy efficient projects.

We have blogged about his before but we are so impressed and excited about this product that we just had to do it again. Traditional spray foams have a Global Warming Potential (GWP) of 725.
