Abstract

Purpose This study aims to introduce the results of a research carried out to develop a prototype of a highly energy-efficient modular detached house, called CASA+ CASA means HOUSE in spanish, adapted to the climatic features of central-southern Chile. The project enables a sustainable alternative to facilitate the reconstruction of the residential areas after the impact of the 2010 earthquake. Design/methodology/approach The methodology is based on an “integrated design process” of a case study that proposes a constructive response that quantitatively and qualitatively improves the initial data of traditional dwellings. The characteristics of the new system have been simulated with specific software to validate the final decisions, considering the cost–benefit ratio. Findings Simulation tools were used to assess and improve the system’s energy performance with respect to present options and to analyse its economic and construction viability. We obtained several economically competitive housing prototypes that substantially reduced energy consumption and the CO2 footprint by between 20% and 80%. Research limitations/implications The prototype has not been developed, as we are waiting for funding, but all its energy features have been simulated. Practical implications Furthermore, this experience also identified similar modifications made to the design of the houses, which revealed general possibilities for improving energy performance. Social implications The origin of this research is a public call for international researchers to improve the quality of the new homes to be built in Chile after the strong earthquake of 2010. The result of the research has been put at the direct service of Chilean society and in other international projects for the construction of low-energy social housing. Originality/value These are the result of a long research aimed at establishing a new architectural model that, in addition to improving the architectural quality of the product, obtains significant improvements in energy consumption and CO2 emissions. The most particular aspect is the practical vocation and its implementation with real construction with the support of construction companies.

CASA+:智利中南部的高能效住房系统
目的本研究旨在介绍一项研究的结果,该研究旨在开发一种高效节能的模块化独立式住宅原型,在西班牙语中称为CASA+CASA,意思是house,以适应智利中南部的气候特征。该项目提供了一种可持续的替代方案,以促进2010年地震影响后居民区的重建。设计/方法论/方法论基于案例研究的“综合设计过程”,该过程提出了一个建设性的回应,从数量和质量上改进了传统住宅的初始数据。考虑到成本效益比,用特定软件模拟了新系统的特性,以验证最终决策。FindingsSimulation工具用于评估和改善系统在现有方案方面的能源性能,并分析其经济和施工可行性。我们获得了几个具有经济竞争力的住房原型,这些原型大大降低了20%至80%的能源消耗和二氧化碳足迹。研究局限性/含义由于我们正在等待资金,原型尚未开发,但其所有能量特征都已模拟。实践意义此外,这一经验还确定了对房屋设计的类似修改,这揭示了提高能源性能的一般可能性。社会影响这项研究的起源是公众呼吁国际研究人员在2010年智利强烈地震后提高新建房屋的质量。研究结果已直接为智利社会和其他低能耗社会住房建设国际项目服务。独创性/价值这些是长期研究的结果,旨在建立一种新的建筑模型,除了提高产品的建筑质量外,还可以显著改善能源消耗和二氧化碳排放。最特别的方面是在建筑公司的支持下,实践职业及其在实际建筑中的实施。
