This chapter first describes the relation between the potential of ventilative cooling to reduce building cooling loads and the role of thermal storage to achieve this; thermal storage could be sensible in the form of exposed thermal mass embedded in the structure of the building or latent in the form of phase change materials embedded in the structure or decoupled from the structure but coupled with the ventilation system. The principles of how thermal storage contributes to passive cooling are described with examples from materialised case-studies. The chapter includes results related to the use of phase change materials in combination with ventilative cooling from an operational system.

This chapter introduces the book’s contents and its structure. It also includes a short description of why Ventilative Cooling (VC) is increasing in importance in a scenario where building cooling needs are growing. The building sector is responsible for about 40% of primary energy consumption; space heating, cooling and ventilation have proved to be the main consumers. Even though great efforts have been made to reduce energy needs for space heating, much less has been done for space cooling and ventilation. However, this situation is bound to change given that energy consumption for cooling is expected to supersede that for heating between 2050 and 2100. The main features of this growth are analysed in consideration of the international style of buildings, the growth in comfort expectations and changes in comfort culture, the growth in internal heat gains, increasing air temperature and urban heat island, as well as the side effects of the advancement in building envelope optimisation to reduce winter consumption (solar gains, airtightness). In order to face these new developments, which are linked with local increases in air temperature due to the thermal by-product of conditioners and related Green House Gas emissions, natural and hybrid solutions are needed. This book focuses on Ventilative Cooling techniques which aim to be a complete and reliable reference for designers and engineers who are working in the field of environmental design and renewable energy in the building sector. In this book Ventilative Cooling boundaries including all relevant information, background issues, techniques and applications are discussed based on the work of an internationally recognised group of experts. This chapter contains a short description of the contents of each part of the book.

This chapter presents the urban microclimate impact on comfort and energy demand by buildings located in high-latitude temperate regions, characterised by higher heating demand compared to cooling. It focusses on London as a case study of such a location and presents results from measurements and computational studies during the last 20 years. The relationship of surface and air UHI in high-latitude cities is first described as well as the relationship between UHI and building energy demand; results from London are used to illustrate the impact. It follows a description of urban albedo outlining contributing parameters. Modelling tools enabling the study of microclimate impact on indoor thermal conditions are then described. Recent results of a study of urban albedo in London and the application of modelling tools are presented.

Heat transfer between encapsulated PCM panels and air plays an important role in PCM-Air heat exchangers. A new design for the encapsulation panel was developed considering practical aspects such as the cost of production and ease of manufacturing, in addition to heat transfer and pressure drop. A number of encapsulated panel surfaces were first investigated via 3D CFD simulations and compared with an existing panel in use by a commercial PCM-Air heat exchanger manufacturer. After validation, 2D CFD simulations were carried out for 32 different geometries to select the most effective design, which was fabricated and tested in the laboratory. Laboratory parameters tested included heat transfer, pressure drop and melting/solidifying. The laboratory results confirmed the improvements of the new panel in comparison with the existing panel and a flat panel. It was found that the proposed design doubled the heat transfer, holds 13.7% more material and the fan can overcome the increased pressure drop.

Buildings are known to be responsible for about a third of energy consumption in developed countries. This situation, together with the fact that the existing building stock is being renovated at a very slow pace, makes it crucial to focus on the energy retrofitting of buildings as the only way to reduce their contribution to these energy consumptions and the consequences derived from them in terms of pollution and climate change. The same level of insulation and the same type of windows is usually proposed for all dwellings in a building block. This article shows that since the improvements required by each dwelling in the same block are different, the proposed solution must also be different. The methodology is proposed for a practical case consisting of an apartment block in Cádiz, a demonstration building of the European RECO2ST project. To achieve the optimum solution for each case, a multi-objective optimization problem is solved: to minimize the annual heating demand of the building and the standard deviation of the annual demand of the different dwellings. Thanks to the use of the proposed methodology, it is possible to bring the building to a Nearly Zero Energy Building (NZEB) level, while avoiding excessive insulation that causes overheating in summer.

A Chinese traditional narrow street, named Cold-Lane, can create a microclimatic zone that provides pedestrian thermal comfort under hot and humid climate conditions. This phenomenon was observed through experimental measurement during the summer of 2016. The heat transfer rate over the pedestrian body surface was calculated to reveal why pedestrians experience a cool sensation, and computational flow dynamics (CFD) simulation was carried out to study the influence of the street aspect ratio on the shading effect. It was found that the perception of thermal comfort can be attributed mainly to the radiation between the relatively cool surrounding walls and the human body, and the wind velocity has little effect on sensible heat dissipation. The cool horizontal and vertical surfaces in the street canyon are mainly due to the shading effect as a result of the small aspect ratio, which is a typical characteristic of the traditional Chinese street. The shading effect of the high walls on both sides creates the cooling effect of this narrow street.

Cool roofs save energy and are particularly suited for low rise buildings in hot climates. This paper presents results of potential energy savings for existing houses in two islands (Sicily and Jamaica) based on validated thermal models. It also presents the lifecycle environmental impact of the cool paint focussing on both the midpoint and endpoint impact categories and compares these with thermal insulation impact. It was found that significant net energy benefits are possible in both locations by a cool roof, more pronounced in Jamaica, which has no heating demand; savings are comparable with thermal insulation reductions. The environmental impact of cool paint is lower than a variety of thermal insulation materials with the exception of water depletion potential. The main hotspots of the cool paint are the production of the polymer followed by the production of the pigment.

The energy performance of urban buildings is affected by multiple climate phenomena such as heat island intensity, wind flow, solar obstructions and infrared radiation exchange in urban canyons, but a modelling procedure to account for all of them in building performance simulation is still missing. This paper contributes to fill this gap by describing a chain strategy to model urban boundary conditions suitable for annual simulations using dynamic thermal simulation tools. The methodology brings together existing physical and empirical climate models and it is applied to 10 case studies in Rome (Italy) and Antofagasta (Chile). The results show that urban climate varies significantly across a city depending on the density of urban texture and its impact on the annual energy demand depends on the region's climate. The urban shadows are crucial in cooling-dominated climates (Antofagasta) while the urban heat island intensity is more important in temperate climates (Rome).

High Concentrator Photovoltaic Thermal (HCPV/T) systems produce both electrical and thermal energy and they are efficient in areas with high Direct Normal Irradiance (DNI). This paper estimates the lifecycle environmental impact of the HCPV/T 2000x system for both electrical and thermal functionalities. Process-based attributional method following the guidelines and framework of ISO 14044/40 was used to conduct the Life Cycle Assessment (LCA). The midpoint and endpoint impact categories were studied. It was found that the main hotspots are the production of the thermal energy system contributing with 50% and 55%, respectively, followed by the production of the tracking system with 29% and 32% and the operation and maintenance with 13% and 7%. The main contributor to the lifecycle environmental impact category indicators was found to be the raw materials acquisition/production and manufacturing of the thermal energy and tracking systems. The results indicate that the lifecycle environmental impact of the HCPV/T 2000x system is lower compared to fuel-based Combined Heat and Power (CHP) and non-Renewable Energy Sources (non-RES) systems.

Recent data of energy consumption by supermarkets in the UK are presented and compared with existing benchmarks in the UK and data from other countries. It is shown that energy intensity has been reduced in large supermarkets (>750m2) in recent years which is consistent with reductions in other countries due to installation of energy efficient technologies for all sub-systems (refrigeration, HVAC, lighting and building). Data for small supermarkets is not segregated in available databases; the presented modelling study, using a calibrated thermal model of a small supermarket, shows the interdependency of sub-systems, location and ratio of displayed products, which can inform system selection.

Hydrogen could be used as a ‘cleaner’ cooking fuel, particularly in communities that rely on biomass and fossil fuels, to reduce local pollution and related health effects. However, hydrogen must be produced using sustainable feedstocks and energy sources to ensure that local impacts are not reduced at the expense of other impacts generated elsewhere in the life cycle. To this end, this paper evaluates life cycle environmental impacts of renewable hydrogen produced in a proton-exchange membrane electrolyser using solar energy. The aim of the study is to find out if hydrogen produced in this system and used as a cooking fuel is environmentally sustainable in comparison with conventional cooking fuels typically used in developing countries, such as liquefied petroleum gas (LPG), charcoal and firewood. The results suggest that hydrogen would reduce the climate change impact by 2.5–14 times to 0.04 kg CO2 eq./MJ compared to firewood (0.10 kg CO2 eq./MJ) and LPG (0.57 kg CO2 eq./MJ). Some other impacts would also be lower by 6%–35 times, including depletion of fossil fuels, summer smog and health effects from emissions of particulates, both locally and across the rest of the life cycle. However, some other impacts would increase by 6%–6.7 times, such as depletion of metals and freshwater and marine ecotoxicity. These are mainly due to the solar photovoltaic panels used to generate power for the electrolyser. In terms of the local impacts, the study suggests that hydrogen would reduce local pollution and related health impacts by 8%–35 times. However, LPG is still environmentally a better option than hydrogen for most of the impacts, both at the point of use and on a life cycle basis.

Cool roofs are most effective in reducing cooling loads and alleviating overheating in locations with high solar radiation and external air temperature. This paper presents results of an experimental study of a low income house in Jamaica and a computational study in three countries around the equator: Jamaica, Northeast Brazil (Recife) and Ghana. A case-study typical of single storey houses in Jamaica was monitored before and after the installation of a cool paint on the roof; on days with average solar radiation intensity of ∼420 W/m2 and ambient air temperature of ∼28 oC, internal ceiling surface temperature is reduced by an average of 6.8 °C and internal air temperature by 2.3 °C. Monitoring results were used to calibrate successfully an EnergyPlus model; similar models were developed for Ghana and Brazil differing in size and/or construction to reflect country specific practices. Annual simulations indicate that internal ceiling surface temperatures are reduced on average by 3.2 - 5.5 oC and internal air temperatures by 0.75-1.2 oC. Cooling demand simulations (setpoint 24 oC) indicate similar annual potential savings in the three locations (∼190 kWh/m2/year) although estimated CO2 emissions reduction differ reflecting electricity generation fuels. Aging of the cool roof has an impact reducing load savings by 22-26 kWh/m2/year.

Nearly Zero Energy Buildings (nZEB) are a significant part of the energy efficiency strategy of the European Union. As buildings represent approximately 40% of the final energy use in Europe, the reduction of their energy demand is key for a sustainable future. This paper takes a qualitative approach and presents data about professional and market barriers, as well as the educational market in relation to the implementation of nZEB policies for new and retrofit buildings in 11 European countries. Different levels of policy enactments and market penetration are reported and are generally found to be more advanced in western and central European countries. Furthermore, gender equality is examined in the building sector in relation to nZEB and presents significant gaps, with a more balanced situation reported in southern Europe. The accreditation and targeted education of nZEB experts is still almost non-existent in the examined countries, and the need for training of building professionals is highlighted as a critical missing component of current policy. This research aims to be the first step towards the creation of educational material and programmes as a mean to accelerate the transition to nZEB.

Highlights•The replacement of fossil fuels with hydrogen for domestic cooking is evaluated.•Focus on developing countries: Ghana, Jamaica and Indonesia case studies.•TRNSYS simulations of community size case studies of the selected countries.•TMY and recent weather data comparison through FS statistics and simulation results.•Novel solar hydrogen potential maps generated for the case study countries. AbstractThis paper evaluates one option to replace traditional cooking fuels in developing economies with a flexible, modular and clean solution of solar hydrogen, based on a numerical and experimentally tested system to address technical and safety issues. The study focuses on Ghana, Jamaica and Indonesia as examples of developing economies using fossil fuels for domestic cooking. Statistical analyses are performed and the domestic cooking demand profiles are created for these countries based on available data and a specific quantitative study in Ghana. The derived cooking demand profiles are used to size solar hydrogen plant case-studies for rural communities based on a TRNSYS numerical model. The results indicate that hydrogen plant sizing and management satisfy annual cooking demands of the communities which are 621.6 kg H2 for Jamaica, 631 kg H2 for Indonesia and 785 kg H2 for Ghana. The effect of the weather data on the simulation is estimated by comparison between TMY and recent weather data for Jamaica. Finkelstein-Schafer statistics indicate differences between the composite and recent weather data, but these prove to have minor effect on simulation results, with 0.9% difference in hydrogen generation. The potential to establish solar hydrogen plants in the countries is further evaluated by creating novel solar hydrogen potential maps.
