	The Gross Heat of Combustion (and HHV or GCV) is measured using a bomb calorimeter, which is a sealed insulated container (bomb) with excess oxygen under pressure, with a water bath, in which a known mass of fuel is burned. The heat released during combustion is absorbed by the water in the bath surrounding the bomb, which causes a measurable temperature increase using the calorimeter's constant (measure of its heat capacity) and the temperature change of the water.

		+	Other related terms include Lower Heating Value (LHV) and Net Calorific Value (NCV), these differ from HHV and GCV which account for the energy released when the water vapour is condensed back into liquid, while LHV/NCV calculations do not.

	This is one of the test approaches to material analysis that is included in the University of Queensland, Australia's Cladding Materials Library. The library lists some 81 materials and product make-ups that constitute potential cladding solutions for buildings, that have been analysed and or tested.

	“Those who design buildings, particularly higher-risk and complex buildings, would benefit from having access to a body of information, such as data from tests on products and materials, reports on serious fires and academic papers. In Chapter 112 we have referred to the Cladding Materials Library set up by the University of Queensland, which could form the basis of a valuable source of information for designers of buildings in general. We recommend that the construction regulator sponsor the development of a similar library, perhaps as part of a joint project with the University of Queensland, to provide a continuing resource for designers.”		“Those who design buildings, particularly higher-risk and complex buildings, would benefit from having access to a body of information, such as data from tests on products and materials, reports on serious fires and academic papers.
