Some of the green that goes with this early player in energy-conscious home building in Bellaire could be the $200,000 price increase over its sale last July, when it went for $1.35 million. The ca. 2002 limestone-and-stucco property with Texas Hill Country stylin’ — designed back then for her own family by architect Kathleen Reardon — popped back up on the market earlier this week with a $1.55 million asking price. Some of the enviro-sensitive elements are visible from the get-go, such as the deep overhangs on the eaves. Others are buried deep in the lot — where a network of caverns 250-ft. deep use underground temperatures to regulate the air conditioning and heating. Solar panels and low-water landscaping also play the green card.
