Abstract

In Chile, about 20% of the energy is consumed by the residential sector. There is consensus in the country that the thermal performance standards for housing are extremely low, explaining the high amount of energy that is currently used for space heating. Nowadays, firewood accounts for close to 50% of this consumption. The high share of this fuel can be explained by its low costs when compared to other alternatives such as kerosene, liquefied petroleum gas (LPG), electricity and natural gas (NG). A direct consequence of this intensive use of firewood are the high levels of air pollution present in urban areas throughout Chile. In Santiago and other cities of the south, particulate matter (PM) 2.5 concentrations exceed the recommended levels (greater than 20 μg/m3 annual average). These environmental pollutants, together with severe levels indoor air pollution, are currently affecting close to 10 million people in the country while generating high rates of heart and chronic respiratory disease as well as premature deaths of thousands. This paper presents a methodology intended to provide critical information in regards to the environmental impacts of improving the thermal performance of new and existing buildings. In order to illustrate its capabilities, the methodology was implemented in representative three Chilean cities (i.e., Santiago, Concepción and Temuco) focusing on the reduction of CO2 and PM2.5 emissions. Overall, this paper demonstrates that the proposed methodology enables empirical assessment of the potential benefits behind the introduction of different thermal performance measures that may be used to inform environmental policies and energy-efficiency measures.
