“…The authorities of environment, housing, energy and health are strongly focusing firstly on enforcing firewood certification, and secondly on stove replacement. The fact that substantial potential for reduction lies on thermal refurbishments, have not yet been recognized (Schueftan & González, 2015). In addition, the subsidies for housing retrofitting have not been monitored in order to show the More investments should be made to monitor and collect in situ information regarding the energy behaviour of different socioeconomic groups, the acceptance of the implemented policies and subsidies, and building energy performance after thermal retrofits.…”

“…Thus, appliance replacement can dramatically change the cost of domestic energy consumption. This change in the price dynamic has not been considered in the current programs (Schueftan & González, 2015 The present research focuses on comparing three housing groups having different implemented strategies for improving the energy efficiency of dwellings. A case study is an empirical inquiry which, in the social sciences, enables investigating a contemporary phenomenon within its real-life context (Platt, 1992).…”

“…Currently, 86% of the firewood is extracted from native forests; this is therefore a very important aspect to regulate. It is not mandatory to use certified firewood and there are as yet few certified suppliers (Schueftan & González, 2015). According to the data managed by the SNCL (El Mercurio, 2014a), only 23% of firewood consumption in big cities is certified.…”

O ver 10 million people in Chile are exposed to concentrations of Particulate Matter 2.5 and 10 (PM 2.5-PM 10) in excess of the acceptable levels. The main source of emissions in the southern cities is the extensive use of firewood in the residential sector for cooking and heating. Low energy efficiency in buildings and inefficient heating appliances increase firewood combustion intensity and atmospheric pollution. This has led to many cities being declared saturated zones of particulate matter, requiring the implementation of various policies under an Atmospheric Decontamination Plan (ADP). The present research focuses on comparing three housing groups having different implemented strategies and subsidies for improving the energy efficiency of dwellings. A survey was designed to analyze occupants' fuel consumption patterns and their comfort perception before and after subsidies was applied. Also, it was registered the dwelling intervention to analyze the effectiveness of housing thermal retrofitting. Results showed that thermal retrofitting in housing is random, and does not respond to an accurate study of the interventions' energy efficiency.

“…This diversity of fuel sources is not found in the UK where 90% of dwellings have a gas fired central heating system with a mean efficiency of 82.5% [9,13]. The modern stoves used in Chile are relatively airtight to minimise indoor emissions [65]. However, smoke exhausted outside may re-enter a house through its infiltration and ventilation openings.…”

Chile is a South American country experiencing greater social and economic development than the majority of its neighbours and whose economy is transitioning from developing to developed status. It is committed to reduce its greenhouse gas (GHG) emissions by 35-45% by 2030, requiring national energy demand reduction. Chile's housing stock is responsible for 15% of its total final energy consumption and so its Government is regulating the construction of new dwellings, although it is difficult to know if this policy will succeed or lead to unintended consequences affecting energy demand, GHG emissions, and occupant health. Measuring the effects in situ is often time and cost prohibitive and so the simulation of archetypal buildings is a common method of investigation. A range of data sources, such as censuses and building permits, are used to develop archetypal Chilean houses with

“…The PPDAs consider four lines of action focused on improving the energy efficiency of homes, the quality of heating systems, the quality of fuels for energy, and education programs. However, these policies have not yielded the expected results and, despite their implementation, ambient air pollution concentrations have continued to increase in all major cities of the region (Schueftan and González, 2015). consequence, the choking of wood-stoves can result in outdoor pollution emissions as much as five times greater than under optimal wood fuel burning conditions (Jordan and Seen, 2005).…”

Abstract *Ambient air pollution is a serious problem in cities in south-central Chile because of massive combustion of wood as fuel for residential heating. To reduce air pollution emissions, Chile's environmental authority has implemented a largescale program consisting of replacing old, highly polluting residential wood stoves with new, less polluting ones. However, to extend burning time and save on wood fuel expenditures, users tend to dramatically constrain the air flow in these new wood stoves, which creates a highly polluting combustion process. To address this issue a behavioral intervention was designed to provide users with feedback on their wood stoves' air pollution emissions. The intervention consists of a metallic sign that aligns with the wood stoves damper lever and that informs users of the level of pollution emissions according to the chosen setting of the wood stove's damper. To assess the effectiveness of this information sign, a randomized controlled trial (RCT) is conducted in selected households in the city of Valdivia, Chile. Results from this intervention show that the information sign induced a behavioral change in wood stove users that translates into a 17.3 percent reduction in residential pollution emissions.JEL classifications: C93, O13, Q53, Q56.
