Central Unresolved Issues in Thermal Energy Storage for Building Heating and Cooling

“…Adding a heat of fusion component to the storage capability of common building materials improves their effectiveness by decreasing the required temperature swing and mass for a given storage capacity. The potential advantages of this approach have been established analytically and experimentally (Berlad et al 1976;Faunce et al 1978;Johnson et al 1977;Habraken and Johnson 1977), but totally satisfactory methods of incorporating phase-change storage into building materials have yet to be developed.…”

Seasonal performance and cost factors of oil or gas-fired boilers and furnaces

“…Still other factors pertain to the merits of the " sizing" of the energy conversion device and its appropriateness when measured against the enthalpy flow demands imposed by the structure it is required to serve. 2,3 One may assess the effectiveness of a structure's design and operating strategy in making optimum use of a given boiler/furnace 13 system. Analyses with these emphases are given elsewhere. '…”
