Central Carolina Community College and its Sustainability Technology Program is dedicated to teaching its students cutting edge "Green Build" technology. As our students enter their careers they will be prepared to make vital contributions towards building sustainable environments. Listed here are many Chatham Cottage construction features representing locally available Green Building products and building practices.p>

This home is a great transition home for people wanting to move towards simplicity and sustainability. This 16 by 30 house can comfortably fit a single person or couple, is great for a guest house for the mom-in-law, and is just as suited for an office space or vacation rental home. This small, tight, energy efficient home is designed to allow the owner to enjoy their natural surroundings, rather than having to worry about how to keep them out.
When buying a home, people often don't think about long term energy consumption and how much that is going to cost. If a house isn't sealed correctly or doesn't have proper insulation, the only person who will pay for that is the owner. Many people are concerned that energy efficient homes are too expensive. Our goal is to provide an energy efficient home using simple, cost efficient building science techniques that are often overlooked in the traditional building community. We aim to provide the consumer with a truly realistic way to save money and energy.
To achieve our goals we are doing the following:
The 2x4 wall studs come from Weyerhaeuser(R) Framer Series lumber, which guarantees that each piece will "start straight and end straight". These walls are sheathed with an inch of Dow(R) foam with an R value of 5.5 to serve as a thermal break and move the thermal mass of the wall framing to the inside of the building envelope. The blue board also serves as an air and vapor barrier. The idea behind using a thicker piece of foam is to move the condensation point into the middle of the sheathing board. The temperature gradient causes the moisture to condense on the outside of the building envelope, allowing for direct control of the moisture level not only in the living area but also in the wall cavity. The design of the heating and cooling system has been optimized to provide the best performance through efficiency and proper sizing. The flooring system uses the 2 by 8 floor joist to tie the band and subflooring together to form a structural diaphragm. The wall framing combined with the Dow(R) sheathing also acts as a diaphragm. The Sill Seal (installed between the bottom plate and subfloor) acts as an air and vapor barrier in a location in which air infiltration is common.
