Advanced glazing and associated materials for solar and building applications: International Energy Agency Solar Heating and Cooling Program Task 18

摘要

Abstract: Following a program definition phase of 2 years, Task18 of the International Energy Agency Solar Heating &Cooling program commenced a 5 year research phase inApril 1992. Task 18 investigates a wide range ofadvanced glazing materials and glazing systems whichinclude monolithic and granular aerogels, transparentinsulation materials, chromogenic materials, evacuatedglazings, low-emittance coatings, solar collectorcovers, angular selective transmittance thin films,holographic and light guide materials, and frame andedge seal technology. In addition to materials-centeredresearch, Task 18 concentrates on measurement of keyglazing properties such as total energy transmittance,U-value, and spectral directional optical properties,and through the use of building energy analysissoftware tools the identification of appropriateapplications, control strategies, and energy andenvironmental benefits to be derived from advancedglazing products. Fifteen OECD countries areparticipating in Task 18 which is led by the UnitedKingdom. !5
