ELIGE MADERA Findings on Wood Construction in Chile The UC Wood Innovation Center (CIM UC-CORMA) made a report based on the third chapter of a research paper conducted by the World Bank entitled "The Construction of Timber Houses in Chile: A Pillar of Sustainable Development and the Agenda for Economic Recovery." From here, they came up with the idea of making a report on the use of wood in construction in Chile, taking into consideration quantitative variables to analyze the reference costs of different houses that are representative of the country. The UC Wood Innovation Center (CIM UC-CORMA) made a report based on the third chapter of a research paper conducted by the World Bank entitled "The Construction of Timber Houses in Chile: A Pillar of Sustainable Development and the Agenda for Economic Recovery." From here, they came up with the idea of making a report on the use of wood in construction in Chile, taking into consideration quantitative variables to analyze the reference costs of different houses that are representative of the country. The information provided by the National Statistics Institute of Chile (INE) and the Technical Division of Study and Housing Development (DITEC) was fundamental to creating this report, in order to know the typology of the houses to be studied. The report divides the wood construction projects into three main focuses: height, climate zone and operational costs. Some findings: HEIGHT It is possible to identify that one- or two-floor wooden houses are, on average, between 0.3% and 6% cheaper, compared to same-sized constructions of galvanized steel and masonry, respectively. But if we analyze medium and high-rise houses, the context changes radically, showing increases of 5% on average compared to two-story wooden houses, with the main cause being the equipment needed to construct high buildings. CLIMATE ZONE The study says that in the northern region, three- to four-story masonry constructions are more affordable than those made of wood and the same is true for the South. However, the situation changes in the central region because, from three stories and up, building with industrialized wood systems are highly competitive. It’s 15% cheaper to build three- and four-story buildings and 7% more expensive for five- and six-story buildings. However, in the southern region, wood is the only material that meets the regulations for buildings of three stories or more. OPERATING COSTS The study points out that operating costs depend to a large extent on the materiality of their heating/cooling systems, since "depending on the climate, homes with greater insulation and fewer thermal bridges can have significantly lower operating costs," according to the report itself. Because of this, when we consider wood-framed houses with extra thermal insulation inside, the cost of heating decreases significantly. In Chile, most of the houses in low-temperature areas have a heating system but those in warmer areas generally do not have air conditioning, as its use is still not widespread. So, the operating costs of a wooden house can be between 23% and 53% lower, taking into consideration the material, comparison area and level of insulation.
