Terraces, as outdoor extensions of food and beverage businesses located in the public realm, have very high potential to activate the streetscape, bring people together and improving urban experiences. Among the consequences of the current COVID-19 pandemic are the recommendations of maximizing outdoor environments when conducting human interactions. Therefore, outdoor eating has dramatically increased throughout the world, with terraces becoming a radical urban change in many streetscapes. The urgency of the situation, and rapid implementation of these changes, has revealed some aspects of this phenomenon that should be considered when adapting the regulations to this new reality. However, the research on their functioning and impact is limited. Additionally, although energy consumption in the architectural and urban field is considered fundamental, research has rarely addressed small business outdoor spaces, placing the focus instead on residential heating or public lighting. This study focuses on the intersection of these two gaps by analyzing a set of terraces in Barcelona and estimating the power installed in their outdoor heating devices. The goal is to determine the potential energy consumed, contrast it with other values more commonly used when researching architectural energy consumption and point out the lack of sustainability of these approaches to providing comfort. The calculations show that the installed power in Barcelona terraces is significant and, when estimating potential consumption, it presents values higher that the average heating consumption of residential units in Spain. These results support two main conclusions: first, the relevance of addressing the means of providing comfort in outdoor urban spaces due to the high magnitude of their potential energy consumption; second, the importance of adapting those systems to outdoor conditions, understanding the needs of the occupants and the limitations of the environment in order to develop sustainable solutions that provide comfort without attempting to heat the air of the street.

The use of vegetation in urban environments is a design strategy which brings thermal benefits at street level, especially in warm climates in hot periods. Urban environments integrate different types of vegetation that modify the thermal composition of public space and therefore, the mean radiant temperature (MRT). The characteristics and surface temperature of the surrounding elements such as vegetation determine the value of MRT. In this study, the temperature of a concrete wall and a wall covered with vegetation are compared under the same conditions. The objective is to determine the influence of vertical vegetation in pedestrians’ thermal perception in a hot period. To this end, a sequence of thermographic pictures was taken with temperature measurements on specific points of both materials. Also, measurements of air temperature, bulb globe temperature and relative humidity were carried out during the same period. The sequence of infrared thermography shows the different temperatures between vegetation and concrete under direct solar radiation, which reaches up to 10 °C in the central hours of the day. The variation of temperature along the measurement sequence is also different in both cases. According to that, vegetation does not reach a temperature as high as other materials such as concrete in hot periods, which contributes to decreasing pedestrians’ heat perception.

One of the main responsible for the heat flux between the exterior and the interior space is the building’s envelope. In order to achieve better interior thermal comfort conditions, it is necessary to control heat gains and losses through it. The aim of this paper is to analyze the role of the façade and the roof in a habitable volume exposed to the celestial vault and their energetic behavior due to the conductive and the radiative exchanges. A volume with no windows, no thermal insulation, no internal gains and with an approximate sky view factor (SVF) of 80% was used as the study case. The case study was modeled on a digital simulation program. Then it was calibrated and validated with measurements of indoor temperature and relative humidity taken on site for approximately three years. Heat flux values were obtained from the simulation program. With the envelope heat flux analysis, it can be concluded that the roof is the enclosure of the envelope that has the greatest influence on the heat flux balance, consequently also on the indoor temperature behavior.

Cities evolve through time, adapting to new needs, uses and dynamics. This study examines a specific transformation, industrial uses, in a particular location, Barcelona. The objective is to develop a methodology that allows to analyze the transformation of the built environment in cities not only as singular elements but as an interconnected system. Through historic and current cartographies, a categorical comparative analysis is performed and the energy needed for transformation of industrial buildings is calculated. The study showed how, if when industrial uses were pushed out from their original location, the transformation of the industrial heritage into other uses had been planned as an overall strategy, the city would have benefited in several ways, including access to open space, preservation of cultural heritage or energy consumption reduction. This methodology can be used beyond this immediate case study, and work as a baseline to understand transformation processes in urban centers and plan for the unavoidable change that every city experiences.

Today, the building sector is one of the greatest energy consumers of the world. Therefore, it is impor-tant that designers think about strategies to save energy at the different stages of the building process,including during its life. Considering that a great deal of energy will be spent in artificial lighting, animprovement in the performance in front of light of the architecture itself could lead to a better vision ofthe spaces, which depends on the quantity and quality of light available and on the architectural char-acteristics as well. One of the most influential aspects is the colour of the space. Here, a case study ispresented in which three coloured spaces were assessed by observers under different lighting condi-tions. Luminance and illuminance measurements were taken to compare these values with the votesgiven. The results query the correlation between measured values and luminosity of three-dimensionalspaces. As a consequence, the choice of a particular colour may increase the sensation of light in a spaceand, therefore, a reduction of energy use in artificial lighting is possible. In addition, architectural designcan take advantage of colour to improve the visual quality of indoor spaces.Postprint (published version
