- Аннотация: In the context of climate change, it is difficult to maintain the energy performance of houses, especially in countries with building codes that regulate the maximum allowed amount of energy that a building can consume. For this reason, there is a need for a review of building standards and adaptation to the context of energy performance in planning future projects. The objective of this research was to ascertain the thermal transmittance of external walls for single-family homes and to establish the energetically optimal thickness of thermal insulation by using an energy simulation to maintain heating energy consumption in conditions of climate change while following the state regulations in the Los Ríos region of Chile. It was demonstrated that for each time period and in each geographical location of the region the optimal U-value of the external walls is different. For a house to have a heating energy consumption corresponding to 90 kWh/m2/year, it must have an optimal average U-value of the walls of 0.49 ± 0.11 W/m2K (year 2006 in the study region); however, for the period 2035–2050, this value is expected to reach 0.78 ± 0.14 W/m2K. In addition, it was shown that designing the house with an energy performance perspective of 15 years helps to reduce the carbon footprint of the use of thermal insulation in the walls by 20%. The results obtained demonstrate the importance of considering the effects of future climate change in the housing design process in terms of both energy and environmental.
