Electric mobility is expected to increase in the following years motivated by environmental awareness and government targets, therefore, a great number of combustion engines cars will be replaced by electric ones. In addition, urban space has become scarcer to house a large number of existing vehicles increasing the number of underground parking. Like cars remain parked here most time of the day being charged, new elements appear, so this transition requires parking infrastructures to match. But, are the millions of underground existing parking ready for it? Given the shortage of regulations and the existing debate, the integration of the systems is not undertaken safely. In this context, this paper seeks to analyze the level of preparation of underground parking through scientific literature and a review of standards detecting conditions and requirements to prevent possible hazards. Although the article is focused on the Spanish context, the detected problems, hypothesis and proposal of solutions can be applied to other countries.

The issue of air pollutants from livestock buildings is prevalent in the literature. Because they and their emissions impact both animal production and livestock building users as well as the outdoor environment. This paper aims to compile and review data available in the scientific literature on the types of pollutants for a better understanding of their generation form, their distribution according to the kind of animal, and the main factors affecting their generation and concentration, i.e., the rearing system, the indoor microclimate, and the manure management.
The elevated generation of pollutants in animal buildings is tied to the dense occupancy in this industrial activity. The indoor air quality is defined according to the type of livestock in animal housing, considering its welfare needs, and the types and concentrations of pollutants generated as a function of the family of animal and the management used in production. The main gases generated are CH4, CO2, H2S, NH3, N2O, in addition to particulate matter and airborne microorganisms such as fungi and bacteria that very negatively affect the health of animals and users of the animal buildings.

The leather industry is an example of circular economy, as it uses meat industry wastes (hides and skins) as raw materials. However, the process of tanning also produces a substantial amount of organic waste. This research project studies the case of a tannery located in Navarra, in the North of Spain, committed to a circular economy and environmental protection, which produces around 2 tons per day of leather shavings and buffing dust and 10 tons per day of discarded bullock hair. The study tackles the challenge of whether the discarded waste material might be used as a new resource for products or processes related with the building sector. Three different types of solid wastes (chromium free tanned shavings, chromium buffing dust, and discarded hair) were categorized and analyzed. The paper examines two proposals to reuse the weekly tons of leftovers (both shavings and hair) produced by the tannery, instead of taking them to an external composting plant or to the landfill. The first exploration path proposed to use the discarded material to obtain biomass for the company's thermal production plant. After establishing the calorific values of the discarded hair and the shavings, these were found to offer competitive value in comparison with the biomass products used at present, such as wood pellets. The second approach to the waste upcycling involved seeking new products in the building sector, acoustic panels in this case. After a mechanical behavior analysis, different bin

The use of thermoelectricity in buildings represents a disruptive alternative for indoor thermal needs as it is a technology that allows the elimination of refrigerants. In this line of research, authors of this study have worked on the design and construction of several Ventilated Active Thermoelectric Envelope (VATE) prototypes. A VATE is an industrial-scale modular prototype designed to be installed in the building facade and thought to be an alternative solution for heating and cooling in Net Zero Energy Buildings. Previous prototype modules have been tested to assess their heat power and performance in heating and cooling mode, which could be considered an initial approach towards the solution of designing VATEs that can be replicated. These works have resulted in an improvement of the COP of the system, the relationship of the Peltier cells and the ventilated facade, as well as with the interaction with photo-voltaic systems. However, the problem of the thermal bridge when the VATE was turned off remained. Taking into consideration the lessons learned from previous construction solutions, the system has been redesigned, prioritizing in this case the reduction (not elimination) of the VATE thermal bridge. This article describes and justifies the solutions developed, presents the results achieved for heating and cooling, and raises points about what could evolve from this issue. (C) 2020 Elsevier B.V.

Conventional cooling systems in large office buildings typically incorporate evaporative cooling towers, despite the drawbacks of direct evaporation. An alternative approach is based on highly selective innovative surfaces capable of daytime radiant cooling, however, prototypes of these cooling radiators have not yet demonstrated a system capable of cooling an actual building. This paper presents a third approach: A hybrid cooling system designed to partly or completely replace a cooling tower using dry heat dissipation panels. Unlike nocturnal cooling radiators, these panels may be integrated into a facade in a vertical position. The hybrid system is described firstly, where two configurations of the system are considered. Then, an evaluation of the hybrid system in comparison to a conventional system is performed by means of a simulation-based study, resulting that the replacement of a cooling tower by cooling panels increases the annual energy consumption by 3.6% compared to a conventional open circuit cooling tower system. However, the decrease in maintenance costs may reduce the annual operational expenses by over 50%. (C) 2020 Published by Elsevier Ltd.

The strategies for thermal regulation and environmental control found in nature are countless. In this article, a parallelism between animals and building energy systems is defined in order to identify and emphasize the immediate opportunities that biomimicry offers for future research. The motivation was the need to find alternative solutions to tackle problems mainly in the efficiency of heating, ventilation and cooling systems. Due to the wide range of possibilities offered by animals, this study is largely limited to the strategies that cold-blooded animals have developed through evolutionary adaptation to the environment.
The method used for the analysis is based on a solution-based approach. Firstly, different animal thermoregulation strategies are defined (biological domain). Then the strategy is analyzed and classified into three categories. This classification is essential in order to formulate the parallelism with building systems (transfer phase). The final step is to identify the potential implementation (technological domain).
This approach has been seen to be useful in creating new research opportunities based on biomimicry. In addition, suitable solutions arising from multidisciplinary team research are presented as promising answers to the challenges that building energy systems face nowadays.

Occupancy schedules in building spaces play an important role in evaluating a building¿s energy performance. This work seeks to identify disparities between different occupancy estimation techniques; standardised occupancy profiles found in literature, business processes¿ based profiles through interviews and accurate profiles from real on-field measurements. The occupancy diversity profiles of secondary spaces in a healthcare facility building are analysed through descriptive statistics and t test methods over different time horizons. Occupancy measurements are obtained by utilising a novel, robust and highly accurate real-time occupancy extraction system which is established through a network of depth cameras. Results indicate that the utilisation of real occupancy data, along with elaboration of the business processes that take place in building spaces have the potential to support more precise profiles in Building Performance Simulation software tools.

The energy used for cooling has increased in recent decades and the predicted future rise in consumption is driving a pressing need for more efficient technologies. Some technologies use environmental sinks as heat dissipation alternatives. This paper presents a model validation with experimental data from a passive vertical cooling panel. The novelty of the solution lies in two main characteristics. The first is that the panel is in a vertical position, and thus the heat sink is the ambient temperature and surrounding instead of the sky temperature. The second is that the panel is north-oriented. Avoiding the sun lengthens the operating time to the entire day, while most studies explore options that are limited to night radiation. The aim is to include this element as a heat exchanger before water moves into the cooling tower from the condenser stage in cooling systems. The results have shown that the model approaches significantly the experimental data with an average error of 1.5% in the dissipated heat. Besides, the cooling capacity of the panel varies from 107 to 230 W/m2 depending on the inlet temperature and fluid flow conditions, confirming the viability of the integration in buildings.

Finding new solutions for energy recovery in buildings is crucial to diminish the energy consumption. Some proposals may unveil innovative products to solve this challenge. However, reinventing and reformulating the configuration of available solutions might be another way to find an inventive answer to the energetic problem. The main aim of this article is to check if several cores connected in a cascade layout and installed in two different rooms can provide a better performance making use of energy from exhaust air. This study was inspired by the rete mirabile of tuna. This strategy proposed by nature has been translated into building services. Thanks to this reinterpretation, a new configuration of heat recovery ventilators (HRVs) has been simulated with CFD software. The results obtained show that up to 44.5% of energy could be saved with the new configuration making it a promising solution and a foreseeable application for energy recovery in buildings.

The amount of energy consumed for cooling purposes is increasing and expected to rise in the following years. The active cooling mechanisms used to meet these requirements can be partially replaced by harnessing environmental conditions and developing passive solutions. Through the multidisciplinary knowledge offered by biomimicry, a bio-inspired solution was developed with the aim of reducing the drawbacks of cooling towers. This experimental study shows the development of a passive cooling panel prototype and attempts to analyse tests carried out in the north of Spain. The results show that with three different inlet temperatures (35, 45 and 55 °C) and a fluid flow rate of 0.5 l/min, the average heat dissipation power per unit area of the panel is 140.4, 284.8 and 309.7 W/m2, respectively. By increasing the flow rate to 1.5 l/min, the heat rejection rate rises to 250.8, 397.5 and 479.6 W/m2, respectively. These outcomes confirm the cooling potential of the passive panel and open the possibility to the development of numerous applications. Further development of this solution would seek the decrease of the peak demand and the reduction of the energy consumption of cooling towers in tertiary buildings or small industry.

The article proposes new ways of work to redesign previous Peltier cells prototypes using biomimetic methodologies. Biomimicry can be a source of fresh ideas to solve contemporary problems. Also in terms of energy saving and efficiency, animals can be of aid. Ectotherms, animals that depend on external factors to be in a range of `living temperature¿, have developed strategies to survive and adjust their metabolism regarding the environment and weather conditions.
Social insects are ectotherm animals. One specimen of these species cannot be autonomous and would die if he is out of his nest for a long or even short time. Previous studies made about bees behaviour in beehives show up an automated and accurate work to maintain nest temperature.
Strategies such as the heat shield or stigmergy have been translated to obtain better control of the air cavity and a decentralized computational control of the equipment.

This paper is comprehended in the study of the application of the biomimicry science in building services and energy management, taking as a reference the case of tuna. Tuna generates heat in the muscles, organs and tissues of the inner area of its body (dark muscles). This heat is distributed in the periphery in order to maintain constant body temperature. From this biological reality, researchers analyse the possibility of altering the heating demand of an office on the basis of the heat conservation strategy applied by tuna, merely modifying the working-spaces. For this purpose, an existing office building with high architectonical quality parameters has been chosen and different scenarios have been defined in order to perform the energy simulations. The case studies correspond to the variations in the floor layout and occupancy density distribution. Besides, they are studied in three European cities with different climate. The evaluation of results is mainly focused on the heating demand since tuna strategy comprises the heat management. It is shown that the arrangement of high thermal load locals affects the heating demand of the building, being more efficient the tuna distribution in order to lower the demand.

The Basilica of Arantzazu is a recognized project, designed by the architects Luis Laorga and Francisco Javier Sáenz de Oíza, one of the most emblematic works of the church architecture of the twentieth-century in Spain. Although widely studied by architectural criticism, nothing is known about its interesting HVAC services, so this article analyzes and puts forward a technical aspect, heating and ventilation, providing critical examination of the abundant and unprecedented existing information about the original design of the main building services in this project. Results include unpublished information, redrawing from original plans and theoretical consideration about the role of the architects in the design and construction of these building services.
