Resumen de Evaluación de los costes y beneficios de la implementación del aislamiento acústico en el mercado residencial de nueva planta en Barcelona
The principie of this research answers to the interest to procure a value for silence. This argument was added to the expectation generated by the "Documento básico de Protección Frente al Ruido (DB-HR) del Código Técnico de la Edificación (CTE)," which incremented the profit demands in buildings and from here comes the next questions: How much do people agree to pay for an acoustically insulated dwelling? Does the willingness to pay overcome the increment in the cost of the building systems which come from the normativity previously mentioned? The work hypothesis states that the cost of the technique-constructive applications included in the CTE to improve the acoustic comfort of housing is lower than the benefits which individuals perceive and convey in their willingness to pay for acquiring a house with these characteristics . The aim is to utter that for the new residential market in Barcelona, the willingness to pay for occupy a house which gives a major acoustic comfort exceed the cost of the implementation of the most restrictive insulated systems . This thesis is structured in two parts : theoretic and empiric. The first one includes the acoustic concepts and microeconomics applied in the valuation environmental goods . The context contemplates the importance of silence , which does not have a value, or if it would have it, in place of a house with a major acoustic insulation; it cannot satisfy the demand in a while. In this situation the contingent valuation method is an instrument that beyond of its interpretation generaliy provides possible answers to the questions requested previously. As for the empiric one, it is estimated the possible over costs related to the ¡ncrement in the isolation and the amount of related profits given to this variation. The proposing intended to create a hypothetical market for people to expose their preferences . This is one of the main attributes of this study. It meant to organize and get through the acoustic simulation of a dwelling which rose up the diverse acoustic isolation levels and the main conditions posed by the barcelones real estate market. The outcomes gotten display the significance of the research presented in diverse situations. The first one is the analysis of the economic impact in the acoustic contamination, discovered in the willing to pay for residing in more acoustic dwellings. This analysis may be the information source for the public and private agents over the trade -off that is generated when the building techniques improve increasing the habitability of dwelling. Taken into consideration the methodology, the relevance is the designed scenery and the evaluation of the benefits related to the DB-HR launching. With the right incentive, people think over those complex situations which affect them (the advantages to improve the acoustic conditions of a house) and it is demonstrated that the contingent valuation method provides reliable information to perform the analysis of public policies. Finally, the econometric models display products which recommend that the ordered logit matches better the questioning format handle and allots reliable valuations in the willingness to pay.
