We’ve mentioned solar-tracking but the systems are usually pictured on a pole in a big grassy yard. This is a Dual-Panel Tracker by Maryland-based Advanced Technology & Research Corp. (ATR) on the roof of a row house in Federal Hill in Baltimore. The install consists of two panels, 235-watts each, on a sun tracking mount with a GPS-controlled drive unit that follows the sun to yield about 30% more than fixed panels.
Traditional home styles plus a net-zero building standard is a winning combination in the Homes at North Pointe development in Frederick, Maryland.
North Pointe was a dormant development whose design pattern was set when developer NEXUS EnergyHomes, Inc., adopted the project. Nexus took the existing set of plans for the project adjacent to Frederick’s historic district and proceeded to “energize” them, according to Mike Murphy, president of Nexus’ construction division, in order to achieve NAHB’s Emerald certification and reach the net-zero goal.
