SOLAR Pine Street showing solar panels installed flat (parallel and tight to the roofing). Performance is diminished due to the lower sun incidence angle and the increase in time that the panels are covered following snowfall, plus re-roofing is complicated. Also the panels were moved up on the roof (westward) to be less visible from the street, and so they are shaded earlier by the high bank on this site, further diminishing performance.

SOLAR Williams Street façade Showing historic detail. Solar panels are mounted on the rear of the building, where they are nearly invisible from the street.

SOLAR Williams Street, Bellows Falls. Solar installation is on the rear of the building and can not be seen from the street without some effort. The panels are mounted at the recommended 45-degree angle, reducing or eliminating snow issues, and increasing performance. The de facto principle of HP review is that the view from the front counts, the view from the rear does not.

SOLAR; WINDOWS; BUILDING ENVELOPE The Windham Housing Trust created 29 apartments in the Daly Shoe Building, a former warehouse. The energy efficient retrofit uses solar panels for domestic hot water.

WINDOWS; BUILDING ENVELOPE Willard Mill, St. Albans. A former factory, the development was remodeled with foam insulation on the interior and aluminum clad windows. Energy performance was increased so that affordability will be maintained at oil prices up to $6 a gallon.

CVCLT property, Barre St., Montpelier. Energy use was cut in half after windows were replaced, siding was removed and exterior rigid foam insulation added, and solar panels for domestic hot water were mounted on the back roof. Building will be able to maintain affordability at oil prices in the $5/gallon range. WINDOWS; BUILDING ENVELOPE; SOLAR
