Do most older homes need weatherization?
Jan 11,2009 | West Union, Iowa

Each year, Northeast Iowa Community Action Corporation (NEICAC) uses state funding to weatherize about 100 homes. On this 100-year-old two-story home, and others like it, weatherization crews have performed a variety of diagnostic tests and implemented low-cost, high-return strategies for improving overall energy efficiency — without extensive modifications.

This 2,500-square-foot home is typical for the area but larger than many of the houses in NEICAC's program. The work done on this house reduced air leakage by almost 50%.

Deck-over-patio doubles outdoor space on a hillside home
Dec 19,2008 | East Greenwich, Rhode Island

The large, wraparound deck not only creates a nice bridge between the house and back yard, it helps balance the entire house on the property. The eastern exposure is elevated above the sloping grade, offering shade and cool breezes in summer, while the southern exposure provides warmth on all but the coldest days in winter. The house is small, so extra outdoor space to enjoy the private wooded lot and abundant wildlife is welcome in every season.

Design approach: Connect the yard to this hillside home on both floors
