Article
This paper discusses the application of Integrated Design Process for the design of low-cost housing in Chile. It aims to question common practice for the development of housing based on prescriptive regulations and non-interdisciplinary work, which has resulted in poor quality building requirements. The first stage consisted in defining performanc...
Article
Currently, there are few studies aimed at evaluating the indoor thermal comfort of specific contexts such as that of Chile, where national standards are based on international references and are not mandatory. For this research, a field study was conducted in 19 buildings in Chile: 10 in Concepción and 9 in Santiago. Thermal comfort surveys and sim...

Los sistemas de certificación de sustentabilidad en las edificaciones se centran en la dimensión ambiental através de criterios orientados al ahorro de energía y la disminución de gases efecto invernadero. Sin embargo, en la actualidad existe una preocupación creciente por la sustentabilidad social centrada en el bienestar y salud de los ocupantes,...
Conference Paper
Full-text available
There is no consensus on the definition of well-being in the built environment, but rather a wide range of approaches that deal with physical, psychological and social dimensions. There is a need for a holistic approach in order to understand what makes a building healthier and positive for occupants' well-being, which is particularly important in...

Few studies focus on researching the potential of sustainable buildings to promote the sustainability of their occupants. Therefore, this study aims at analyzing the use of LEED credits, with the intention of promoting pro-environmental behaviors. The methodology is exploratory in nature, with a descriptive logic, and comparatively analyzes LEED-ce...
Article
The evaluation of productivity in office buildings is particularly complex; studies indicate that occupants’ perceptions reflect thermal conditions and are therefore an important element to consider. This research reveals the interrelationships and relative influences of the thermal environmental factors of offices on the perceived productivity of...

Resumen El calentamiento global, sumado al fenómeno de isla de calor, ha originado alzas en las temperaturas y con ello riesgo de sobrecalentamiento en las viviendas emplazadas en entornos urbanos, cada vez más sobrepoblados. Si bien las crecientes demandas de refrigeración pueden ser cubiertas mediante la ventilación natural, muchas veces ésta no...
Article
Full-text available
Between the ages of 6 and 18, children spend between 30 and 42 h a week at school, mostly indoors, where indoor environmental quality is usually deficient and does not favor learning. The difficulty of delivering indoor air quality (IAQ) in learning facilities is related to high occupancy rates and low interaction levels with windows. In non-indust...
Article
This study examines the perceived productivity of office occupants in moderate thermal environments in Chile. Specifically, it analyses environmental parameters and contrasts participants’ self-reported answers to cross-sectional and retrospective questionnaires. To this end, data were collected for one day in winter and one day in summer, in eight...

Today, identifying energy poverty is one of the scientific community's challenges. In this sense, using Geographic Information Systems (GIS) assumes getting to know which areas are the most vulnerable. This study considers the development of a new territory energy poverty evaluation indicator, called Poverty Adaptive Degree Hourly Index (PADHI). Th...

People's subjective response to any thermal environment is commonly investigated by using rating scales describing the degree of thermal sensation, comfort, and acceptability. Subsequent analyses of results collected in this way rely on the assumption that specific distances between verbal anchors placed on the scale exist and that relationships be...
Article
Since occupant behaviour impacts the energy performance of buildings, its study is relevant in order to bridge the performance gap. While the factors influencing occupant behaviour have been established, most studies have focused on those factors that motivate the action, such as environmental and temporal conditions. Contextual factors including s...
Article
Shared office spaces represent a challenge regarding thermal comfort. They have a diversity of occupants and expectations, and they require social interaction, which could imply restriction in adaptive actions, contrary to individual areas that usually allow total control. Hence, this paper aims to identify differences in thermal comfort criteria a...

Article
Full-text available
Thermal discomfort is one of the main triggers for occupants’ interactions with components of the built environment such as adjustments of thermostats and/or opening windows and strongly related to the energy use in buildings. Understanding causes for thermal (dis-)comfort is crucial for design and operation of any type of building. The assessment...

This study aims to determine comfort temperatures in 18 office buildings located in two Chilean cities. The methodology was based on a longitudinal fieldwor...
Article
Full-text available
As part of a thermal retrofitting process of existing housing, energy and thermal performance is normally predicted by dynamic simulation that supposes standardized patterns of building use, without considering the key role of the users in building's energy consumption. This represents a weakness in how the evaluation and design of retrofitting pro...
Article
Full-text available
Adaptive comfort plays an important role in defining comfort standards when considering comfort in buildings in free-running mode, including adaptation to external temperatures, opening windows and changing clothing. In this regard, two international standards provide the fundamental basis to model the necessary equations: EN 16798 (formerly 15251)...

In shared spaces, adaptive actions can be limited by a coexistence factor, which has an impact on thermal expectations. This study aims to compare the perception of thermal comfort, comfort temperature and adaptive actions in individual and shared offices. Fieldwork was carried out in 9 office buildings in Concepción (36°S) and 8 in Santiago (33°S)...
Conference Paper
Most of the operational energy needed by the housing sector is used to compensate energy losses or thermal gains through the building’s envelope. As a result, any improvement in the thermal behavior will provide important opportunities to reduce energy consumption. This research analyzes improvements in the thermal envelope in social housing in the...
Article
Currently, energy performance indicators for buildings are associated with the primary energy source consumption, CO2 emissions or net energy distribution, which together set the building’s energy efficiency. The evaluation is frequently based on setpoint temperatures and hours of operation. However, these fixed parameters are not suitable for soci...
Article
Fuel poverty is commonly associated with fuel price, energy consumption, income and building features to maintain comfortable conditions. Most studies are based on existing conditions with future macro level predictions. Therefore, there are a lack of micro scale policies and further in-depth research is needed based on the multivariable complexity...
