Choosing the most appropriate insulation material on the external walls
of a building deserves serious attention. The present work is concerned with
the economic and environmental assessment of using different insulation
materials on the external walls of buildings located in four different
degree-day regions. For this purpose, optimum insulation thicknesses were
investigated for fibreglass, expanded polystyrene, glass wool and phenolic
foam. Consequently, energy savings over a period of 10-years, payback periods,
fuel consumptions and CO₂ and SO₂ emissions are
determined for natural gas, coal and LPG. The annual heating and cooling energy
required were estimated by using heating and cooling-degree days methodology. It
is deduced that the cities of Antalya and Şanlıurfa positioned in the first and
second degree-day regions in Turkey, respectively, were not able to save energy
for fibreglass as an insulation material with natural gas as fuel. The result
demonstrated that the amount of energy savings fluctuates from 1.91 to 368.58 TL/m²
in the event of employing different fuel types for heating, change between 2.74
and 399 TL/m² in case heating and cooling requirements are provided
together at externally insulated walls of buildings. Payback period ranges from
0.081 to 3.28 years for heating and cooling together. Reductions in emissions
fluctuate between 45.65-86.81 % for coal, 31.03-83.21 % for natural gas and
69.64-92.49 % for LPG.
