The capacity of ground-source heap pumps (GSHP) is excluded; data of current installed capacity is after Zheng et al. ([2005]; [2010]); data of strategic target is from the Working Group Report on Mid-to-Long Term Development Strategy of Energy in China ([2011]).
Further ground improvements increased the official capacity of the ground to 183,388 in 1937, but the SFA were only allowed to issue 150,000 tickets for games.
However, for intermittent operation mode, both thermal conductivity and specific heat capacity of the ground, particularly the grouting materials, affect the ground thermal energy extraction.
They combine the relatively small installation cost of conventional horizontal ground heat exchangers and the high heat exchange capacity of vertical ground heat exchangers.
The possibly unknown parameters identified may comprise the thermal conductivity and volumetric heat capacity of the ground or grout, as well as the pipes spacing and initial ground temperature.
This meant that ground safety requirements were met and in September 1989 it was announced that the capacity of the ground had been increased to 14,628.
The two-tier propped cantilever Portman Stand was built along the east side of the ground in place of the existing terraces in 1971, providing 3,500 additional seats and increasing the capacity of the ground to approximately 37,000.
The capacity of the ground to absorb settled wastewater depends largely on the texture of the soil (i.e., relative amounts of gravel, sand, silt, and clay).
Variations in volume and bearing capacity of the ground due to changes in the permafrost constitute one of the major problems in Arctic construction.
Even then hosting games was contingent on proving that the 8,000 permanent capacity of the ground could be extended to 20,000 for the World Cup.
