“…It has also to be stated that the optimum insulation thickness in this work has been found at 4 cm, while in a previous work, it had been found at 6 cm [23]. These values are close to each other but the reason for this difference is based on the different examined installations between this work and the work [23] with solar assisted heating systems.…”

“…The examined case is a domestic building and it follows the operation program according to KENAK. More details about the investigated building are included in Table 2 [22,23]. Generally, typical values have been selected for the various parameters in order for the conclusions of this work to be general and not specific.…”

“…All the external walls (except the roof) have five layers, as follows: 1.5 cm plaster (outer layer), 12 cm brick, 0-8 cm insulation, 12 cm brick, and 1.5 cm plaster (inner layer). The outer layer of the roof is a cement layer of 20 cm, the second is an insulation layer (if More details about the investigated building are included in Table 2 [22,23].

“…The above equation shows that there is a constant part of the insulation installation at 7 €/m 2 (of insulation area) and a varying cost of 2 €/m 2 cm (of the insulation layer and insulation thickness), according to the literature [23] for Greek climate conditions.…”

“…They found that the use of 25 m 2 flat pale collectors coupled with a heat pump led to the minimum electricity consumption. Moreover, Tzivanidis et al [23] examined different solar heating systems for different insulation scenarios in buildings and found the optimum insulation thickness to be around 6 cm for Athens. In another important study, Dascalaki et al [24] stated that the addition of insulation in the old Greek buildings (built before 1980) can lead to the proper energy consumption reduction that is demanded in Greece.…”

The most important parameter in the design of the building envelope is the insulation thickness, because it dramatically influences the heating and cooling loads. The objective of this study is the investigation of different insulation scenarios for the four climate zones of Greece and, more specifically, the cities Heraklion, Athens, Thessaloniki, and Florina. The insulation thickness is examined up to 8 cm and the optimum thickness is determined by the minimization of the simple payback period in order to design a cost-effective system. Moreover, the primary energy consumption, the heating/cooling loads, and the equivalent CO2 emissions are calculated. Furthermore, a multi-objective evaluation procedure of the various insulated scenarios is conducted in order to show the relationship between the energetic and the financial optimization. Generally, it is found that the optimum insulation thickness is around 4 cm for all the climate zones using financial criteria, while the energy criteria indicate higher thicknesses. These results can be applied to the suitable design of Greek residential buildings.
