radiation , solar air temperature ,empirical methods to evaluate heat transfer through walls, and
roofs, TETD and its determination by calculation and tables ,Heat gain through glass ,Solar heat
gain factor, use of equations and tables ,shading of glass ,solar chart and its use .shading of
glass ,solar chart and its use, shading devices and its selection ,load due to other sources,
stack effect ,different methods of calculating cooling load as per ASHRE-some brief idea(other
than TETD methods)
