The absence of vegetation in urban areas contributes to the establishment of the urban heat island, markedly increasing thermal stress for residents, driving morbidity and mortality. Mitigation strategies are, therefore, needed to reduce urban heat, particularly against a background of urbanization, anthropogenic warming and increasing frequency and intensity of heatwaves. In this Review, we evaluate the potential of green infrastructure as a mitigation strategy, focusing on greenery on the ground (parks) and greenery on buildings (green roofs and green walls). Green infrastructure acts to cool the urban environment through shade provision and evapotranspiration. Typically, greenery on the ground reduces peak surface temperature by 2–9 °C, while green roofs and green walls reduce surface temperature by ~17 °C, also providing added thermal insulation for the building envelope. However, the cooling potential varies markedly, depending on the scale of interest (city or building level), greenery extent (park shape and size), plant selection and plant placement. Urban planners must, therefore, optimize design to maximize mitigation benefits, for example, by interspersing parks throughout a city, allocating more trees than lawn space and using multiple strategies in areas where most cooling is required. To do so, improved translation of scientific understanding to practical design guidelines is needed. The urban heat island effect poses increasing morbidity and mortality challenges in a warming world. This Review discusses how urban vegetation — specifically, green parks, green roofs and green walls — can be used as a strategy to mitigate heat.

Measurement and verification (M&V) has become necessary for ensuring intended design performance. Currently, M&V procedures and calculation methods exist for the assessment of Energy Conservation Measures (ECM) for existing buildings, with a focus on reliable baseline model creation and savings estimation, as well as for reducing the computation time, uncertainties, and M&V costs. There is limited application of rigorous M&V procedures in the design, delivery and operation of low/zero energy dwellings and settlements. In the present paper, M&V for four pilot net-zero energy settlements has been designed and implemented. The M&V has been planned, incorporating guidance from existing protocols, linked to the project development phases, and populated with lessons learned through implementation. The resulting framework demonstrates that M&V is not strictly linked to the operational phase of a project but is rather an integral part of the project management and development. Under this scope, M&V is an integrated, iterative process that is accompanied by quality control in every step. Quality control is a significant component of the M&V, and the proposed quality control procedures can support the preparation and implementation of automated M&V. The proposed framework can be useful to project managers for integrating M&V into the project management and development process and explicitly aligning it with the rest of the design and construction procedures.

Nowadays, the design and use of multi-functional mortars has increased significantly, with interesting applications in the green building and cultural heritage conservation sectors. A key point for a correct adoption of these innovative materials is their behavior along time and their resistance to the weathering. The objective of this project was to define the performance and durability of innovative mortars, in order to use them correctly and to avoid irreparable damage over time. For the development of this project, lime–metakaolin and hydraulic lime–metakaolin based mortars (hereinafter called A, B), as well as A and B with the addition of nano-TiO2 and perlite (hereinafter referred to as A+, B+), have been tested. The focus of the work was to carry out preliminary tests to evaluate the performance and durability characteristics of these mortars, verifying their behavior over time through exposure to artificial aging cycles, including thermal shock cycles in saline solution aerosols, freeze cycles in vapor aerosol, and aging by heat treatment at high temperatures. Before and after each artificial aging cycle, weight measurements, and macroscopic and microscopic observations were performed in order to evaluate possible structural changes. The characteristics of the mortars were assessed by determination of the apparent volume mass, mechanical properties, such as compressive and bending strength, water absorption, whereas their self-cleaning capacity was measured by methylene blue degradation test under UV and solar irradiation. The results obtained show degradation effects in the mortar samples due to aging after each test, and indicated that mortars with perlite and nano-TiO2 are the best-performing ones, both from the durability and energetic point of view, rendering them suitable for applications in the green building sector and the conservation of cultural heritage.

In being aware that some factors (i.e. increasing pollution levels, Urban Heat Island (UHI), extreme climate events) threaten the quality of life in cities, this paper intends to study the Atmospheric UHI phenomenon in Bari, a Mediterranean coastal city in Southern Italy. An experimental investigation at the micro-scale was conducted to study and quantify the UHI effect by considering several spots in the city to understand how the urban and physical characteristics of these areas modify air temperatures and lead to different UHI configurations. Air temperature data provided by fixed weather stations were first compared to assess the UHI distribution and its daily, monthly, seasonal and annual intensity in five years (from 2014 to 2018) to draw local climate information, and then compared with the relevant national standard. The study has shown that urban characteristics are crucial to the way the UHI phenomenon manifests itself. UHI reaches its maximum intensity in summer and during night-time. The areas with higher density (station 2—Local Climate Zone (LCZ) 2) record high values of UHI intensity both during daytime (4.0 °C) and night-time (4.2 °C). Areas with lower density (station 3—LCZ 5) show high values of UHI during daytime (up to 4.8 °C) and lower values of UHI intensity during night-time (up to 2.8 °C). It has also been confirmed that sea breezes—particularly noticeable in the coastal area—can mitigate temperatures and change the configuration of the UHI. Finally, by analysing the frequency distribution of current and future weather scenarios, up to additional 4 °C of increase of urban air temperature is expected, further increasing the current treats to urban liveability.

Extreme weather conditions affect human health. This study analyses the association of high and low temperature with cardiovascular and respiratory diseases on people over 65 years old for the years 2007 to 2015, in the region of Chania, Greece. The mortality is examined by time series analysis and further investigated by Poisson, and Negative Binomial regression, showing that one-lag in maximum temperature strongly affects the health of the elderly. Finally, cluster analysis is used from May to October, which is confirmed by discriminant analysis.

Buildings are the dominant end users of energy, as well as the largest contributors to CO2 emissions due to fossil fuels. As an investment, buildings possess the slowest turnover of capital stock, but also comprise the majority of any country’s capital assets. Energy efficiency is thus extremely important in buildings, since it can offer expanding instead of diminishing returns, rendering the adoption of novel technologies imperative for the building & construction (B&C) industry. Designing low energy or zero energy buildings for hot and humid regions is a great challenge. Under climatic conditions of increased rainfall and humidity coupled with high ambient temperatures, typical energy efficiency technologies are not always sufficient. The aim of the present chapter is to focus on the most promising building energy technologies for hot and humid regions. The chapter is divided into three sections. The first section focuses on the building envelope technologies and more specifically to the incorporation of greenery in walls, facades and roofs as well as reflective technologies. The second section is dedicated to the active energy systems for hot and humid regions with specific focus on the desiccant air-conditioning systems. Finally, a series of case studies are presented in the third section.

As Greece's population ages, a number of challenges are presented in order to provide a healthy living environment for the elderly. Senior citizens have unique requirements for the indoor environment due to physiological changes occurring with age, which render them vulnerable to extremes of heat and cold. The aim of this work is to investigate the thermal experience of senior citizens in Crete, examining their thermal sensation, preference and adaptive responses to improve their thermal comfort in their residences. A questionnaire survey was conducted, involving 30 older adults living in the Heraklion district, including both the city of Heraklion and two villages. In addition, the ethical dilemmas emerging from thermally caring for people with dementia are discussed, through interviews given by the caretakers of two dementia sufferers living in Crete. The findings of this work indicate that the elderly consider more important to heat their homes in winter than to cool them in summer, as their expenditure for heating is larger than their expenditure for cooling. Furthermore, their thermal sensation (TSV), thermal comfort (TCV) and thermal satisfaction (TSAV) votes indicate that more elderly feel cold or cool in heating season than warm or hot in cooling season and as a result, there is greater dissatisfaction with the thermal environment in heating than in cooling season. In addition, the survey indicates a preference among the elderly for a warmer thermal environment in winter than a cooler in summer. Finally, the interviews given by the caretakers of two dementia sufferers display the ethical concerns emerging, in terms of who is in charge over the thermal conditions and the protection against extremes of heat and cold in summer and winter respectively.

Demand Response (DR) is a fundamental aspect of the smart grid concept, as it refers to the necessary open and transparent market framework linking energy costs to the actual grid operations. DR allows consumers to directly or indirectly participate in the markets where energy is being exchanged. One of the main challenges for engaging in DR is associated with the initial assessment of the potential rewards and risks under a given pricing scheme. In this paper, a Genetic Algorithm (GA) optimisation model, using Artificial Neural Network (ΑΝΝ) power predictions for day-ahead energy management at the building and district levels, is proposed. Individual building and building group analysis is conducted to evaluate ANN predictions and GA-generated solutions. ANN-based short term electric power forecasting is exploited in predicting day-ahead demand, and form a baseline scenario. GA optimisation is conducted to provide balanced load shifting and cost-of-energy solutions based on two alternate pricing schemes. Results demonstrate the effectiveness of this approach for assessing DR load shifting options based on a Time of Use pricing scheme. Through the analysis of the results, the practical benefits and limitations of the proposed approach are addressed.

Urban heat island (UHI) can significantly affect building’s thermal-energy performance. Urban materials absorb solar and infrared radiation and the accumulated heat is dissipated in the atmosphere increasing further the air temperature. Roofs are envelope components which with advanced solutions such as cool roofs or green roofs can provide significant energy savings in air-conditioned buildings and improved indoor thermal conditions. By means of dynamic simulations in EnergyPlus software a numerical comparative analysis between these two solutions was done in a tropical climate like Singapore’s, taking into account climatological, thermal, optical and hydrological variables. Simulations of a typical summer day in Singapore were assessed to determine (i) UHI reductions for different green/cool roof scenarios; (ii) the diurnal heat fluxes dynamics and (iii) the buildings’ thermal energy reduction for the investigated cases. The results show that during peak periods (9 am to 5 pm) cool roofs reduce heat gain by about 0.14 KWh/m2 (8%) and green roofs mitigate considerably less to about 0.008 KWh/m2 (0.4%). And for the whole of a summer design day, cool and green roof reduces heat gain by 15.53 (37%) and 13.14 (31%) KWh/m2 respectively. The numerical simulation results confirm that an appropriate selection of roof materials contribute to the reduction of the negative effects of UHI but experimental data for air-conditioned buildings are yet to be carried out.

School buildings constitute a rather special case of buildings when it comes to energy performance since the operational costs for heating, cooling and ventilation are usually far less important than the achieved thermal comfort, indoor air quality and lighting levels due to the very sensitive subject of students’ health, well-being and ability to attend lessons Moreover, there is a significant margin for improvement in school buildings’ energy performance and indoor environmental quality. The aim of the present paper is to present the design and energy technologies of a zero energy school in Greece. The energy performance of the zero energy building is analysed. A reduction of the energy demand by almost 68% is accomplished while a significant improvement of the indoor thermal comfort is achieved through the zero energy building design.

The phenomenon of heat island increases the urban temperature and the energy demand for cooling, as well as worsens the comfort and environmental conditions in the urban environment. In order for the consequences of the phenomenon to be counterbalanced, important mitigation techniques have been proposed. The pavements cover a very high percentage of the urban surface and contribute to a significant degree to heat island’s growth in cities and towns. The use of cool pavements achieves significant decrease in the surface temperature as well as in the flow of sensible heat towards the atmosphere. Therefore, it seems to be one of the most important proposed areas of mitigation as far as the aforementioned phenomenon is concerned. This assignment deals with the development and experimental testing of a new technique for the mitigation of the urban heat island, this of the corporation of photovoltaics in pavements. The objective of this assignment is to evaluate their contribution in the mitigation of the phenomenon. The experimental procedure was divided in two time periods: the one took place during the summer–autumn 2012 and the second during the summer 2013. The measurements were done on a daily basis in different weather conditions. In addition, the results were checked by a theoretical mathematical model. The whole measuring campaign indicated that lower temperatures were measured on the PV pavement than those measured on the other two materials (soil, asphalt). The numerical predictions are compared with the experimental data where similar results are found. In order for the contribution of these pavements to the improvement of urban microclimate to be measured, a simulation of an appropriate model took place. More specifically, the model Envimet 3.1 was applied in one particular area of Athens with and without the (incorporation) of the photovoltaic pavement. The outcome of the aforementioned experiment proved that the incorporation of the photovoltaic pavement can achieve a surface temperature decrease of 5 K as well as a decrease in the ambient temperature of almost 1 K.
