    I’d been wondering when they would get around to this, once I saw how they went about constructing the outer walls of the basement of Graystone, the ones that keep the dirt from collapsing while they construct the bottom floors. They drilled hundreds of holes at an angle, maybe six feet deep and 1.5 ft diameter, load each up with rebar and then stuff in concrete. Some extend under 8th Ave.

    I kept expecting the contractor to insert coils of water pipe before they stuffed in the concrete. That’s what heat pumps need to cool down warm HVAC water to subterranean ground temperatures, say 55degF.

    Have architects really been ignoring such opportunities all this time?
