Net zero energy is accomplished by generating electricity with solar power and conserving energy with an insulated building envelope and high-efficiency appliances.
A comfortable home environment is created by a balanced heating, cooling and ventilation system which keeps the house at a medium temperature and keeps the air fresh.
The indoor air quality was improved with a whole-house air filter and point-of-entry water filtration system. Low or no VOC materials were used in the cabinets as well as in the paint and finishes.
The reduction of water use is achieved by installing low flow fixtures and appliances, a recirculation pump, and by reconfiguring the plumbing for the addition of a gray water system.
To preserve the historic elements of the house, the original tiles, windows, and woodwork were reused. To conserve resources, sustainable and recycled materials were selected.
