“…Buildings are responsible for 40% of the total energy use [1] and according to the European Commission 80% of the population will be living in already existing buildings by the year 2030 [2]. One measure that can contribute to improve energy sustainability is to increase the energy efficiency in existing buildings [3].…”

Buildings are responsible for 40% of the total energy use and 36% of total GHG emissions within the EU. Materials science offers solutions that when combined can offer energy savings in building sector. In this study, high reflectance coating and thermal storage capacity are combined with the aim of improving energy efficiency in buildings. For this issue a multifunctional pigment having a phase change material adsorbed on its surface and a high total solar reflectance has been manufactured.The total solar reflectance of the pigment will make the paint to reflect the sunlight radiation in the infrared part of the spectrum reducing the amount of absorbed radiation.This high reflection provides a surface level effect as is a passive stimulus-responsive solution that acts with sunlight radiation.On the other hand, the thermal storage capability provides a bulk level effect as is passive stimulus-responsive solution acting by temperature changes, making it possible to use constructive materials as a thermal energy storage media. The preparation process is described and the pigment is characterized conveniently. The thermal performance of corresponding pigmented coatings was evaluated by a simulated experiment in which two boxes were covered with the coating containing the multifunctional pigment and traditional pigmented coating on their tops. The indoor air temperature and the interior temperature of the substrate were measured obtaining differences of 4-5•C.

“…Los esquemas de evaluación tales como LEED (US), BREEAM (UK), DGNB (Alemania), y CES (Chile) y muchos otros, han estimulado al mercado inmobiliario y al gobierno proporcionando más confianza en la sustentabilidad de un edificio (Wu et al, 2016;Ramírez-Villegas et al, 2016;Seinre et al, 2014). Normalmente las planillas de estos sistemas se basan en créditos para cada criterio y reconocen diferentes tipos de construcciones, etapas, y categorías de certificación y llenan mirando los planos o copiando/pegando información de diversas fuentes.…”

The paper discusses the intersection of two main agendas for Chilean governments that are BIM (Building Information Modeling) and BEAM (Building Environmental Assessment Methods). It shows the state-of-the-art in both fields in Chile as well as in the world, it discusses some previous efforts of integration; it found some new opportunities for collaboration and finally proposes a new framework that brings together BIM and BEAM. The development of the method includes BIM Models, databases and spread sheets for building energy Certification, it finally provides a semi-automatic environment where architects model their design in BIM and this Information is used as an input to the certification process. Potentials and risk of this method are discussed.

“…Housing, during its full life cycle, is responsible for 40% of the energy consumption and 36% of the greenhouse gas (GHG) emissions in the European Union (EU) [3]. Consequently, priority has been given to reducing energy consumption and GHG emissions by 30% and 40% respectively, in terms of the 1990 levels, by 2030 [4]; a second phase aims for reductions of 80% by 2050 [5]. In addition, the EU also forecasts that by 2030 80% of the population will be living in preexistent housing, with less construction and more rehabilitation, which will lead to an increase of 1% in energy consumption due to the need for upgrading [4].…”

In specific terms, housing (operation phase) is responsible for 27% of energy consumption in the EU, generating 225 billion Euros and 630 million tons of CO 2 [6]; more than half of this consumption is due to heating and refrigeration [7].…”

A Comparison of Energy Efficiency Certification in Housing: A Study of the Chilean and Spanish Cases

et al. 2019

Faced with implementing policies that seek to improve the energy efficiency of housing and reduce the impact of CO 2 emissions, several countries are introducing (unilaterally or by international agreement) energy certification systems that allow the effects of these policies to be evaluated. This study aims to compare the energy efficiency certification systems in Spain and Chile, identifying convergent and divergent parameters, enabling the existing gaps to be identified and improvements noted for both systems. To do so, 20 sample dwellings in Santiago de Chile were evaluated, along with the local calculating tools in both countries. The analysis considered the aspects of regulation, its reach, the characterization of the models and the necessary indicators. The comparison identified, among others, differences such as obligatory implementation of the system, a study of the existing buildings in the focus area, the prevailing indicators for evaluating the effects of the buildings, the low incidence of mixed energy systems in the Chilean system and the possibility of proposing and evaluating improvements in the Spanish system. As a result, higher energy requirements and greater CO 2 emissions were identified in the Chilean system, reaching differences of 42 kWh/m 2 /year in consumption and 14 kgCO 2 / m 2 /year in emissions with regard to the Spanish qualification. The results of this comparison have facilitated the identification of improvements that will increase the evaluation standards of the Chilean system.
