Producer displays knack for outdoor living promotion

LoJac Materials dedicated a paver, segmental retaining wall unit and veneer stone display last month, gearing up for design advice and package sales as outdoor living trends surface in the middle Tennessee market. The 5,500-sq.-ft. array of decorative pavements, steps, and wall effects—along with pergola and veneer stone hearth—is adjacent to the sales office of the producer’s Lebanon, Tenn., headquarters. It contains in excess of 50 products, including wall units from three LoJac Materials plants, and pavers from Red River Concrete Products in Clarksville, Tenn.

EPA helps bring permeable pavers to streets of San Francisco

The Environmental Protection Agency’s latest endorsement of pervious or permeable concrete pavements is reflected in a $492,000 grant funding nearly a third of San Francisco’s Newcomb Model Block Streetscape Improvement Project. Mayor Edwin Lee and EPA Pacific Southwest Region 9 Administrator Jared Blumenfeld staged a groundbreaking last month at the site, where removal of old concrete and asphalt will make room for 13,000 square feet of pervious concrete pavers in roadway parking lanes and sidewalk landscape strips.

Green infrastructure PUSH supports pervious, permeable pavements

As part of efforts to promote cities’ use of green infrastructure, U.S. Environmental Protection Agency points to such practices as pervious and permeable pavements—plus rain gardens, green roofs, infiltration plants and rain harvesting—as wet weather management tools that are cost-effective, sustainable and can reduce stormwater runoff polluting the nation's waterways.

Paving stone-actuated heat exchanger garners green grant

The developer of ThermaPaver, an insulated aluminum panel potentially functioning as an all-climate heat exchanger, is one of six University of New Hampshire Green Launching Pad grant recipients. Portsmouth-based Therma-Hexx LLC notes that its device makes full contact with the undersides of ground- or pedestal-mounted, 2-ft.-square concrete paving stones, transferring their solar-generated heat via a bioglycol fluid to a domestic water tank or swimming pool—cooling the pavement as well. The closed-loop ThermaPaver technology can convey heat to or source it from geothermal systems and, in the winter, reverse the heat transfer process to melt snow and ice.
