Globally, fast-tracked urbanization has led to diversified environmental challenges since the time of the industrial revolution. Among the challenges faced, Urban Heat Island (UHI) is caused by the replacement of natural materials with man-made ones such as concrete, asphalt, and increased anthropogenic heat production, among other factors. This study is on understanding the reasons behind UHI, its effects, and finding out proper strategies for mitigation in the context of Bangladesh. Among many ways, proper interior and exterior vegetation, sufficient wind flow, and appropriate building materials are chosen to be the proper methods to reduce UHI effects in Bangladesh. CFD analysis has been carried out to understand the effect of vegetation, wind flow, and different material to mitigate UHI. An estimation of the effect of temperature reduction in energy efficiency is also done. It is observed that a significant amount of energy can be saved by reducing the cooling load if these suggestions are followed. The study shows that the temperature is decreased up to 3°C with the increasing vegetation on exterior walls and rooftop. By using Wood Plastic Composite (WPC) on the rooftop as a phase change material, temperature is decreased around 4°C. By using all conditions (rooftop, sidewall, interior vegetation & PCM on rooftop) together temperature could be mitigated around 5°C.

The need to increase food production and match the food security demands under climate change impacts generate the force for developing aquaponic system. An aquaponic system was established at the Central Laboratory for Agricultural Climate (CLAC), Egypt, to investigate the effect of tomato plant density (2, 4 and 6 plants / m2) on tomato and fish production as well as the quality of rare water. Nutrient film technique (3 m length) used to produce tomato integrated with aquaculture of tilapia fish. Vegetative growth characteristics and yield parameters of Tomato as well as tilapia yield parameters plus the nutrient contents of rare water were recorded.
The revealed results indicated that increasing the tomato plant density from 2 up to 6 plants / m2 led to a decrease in the No. of leaves, total leaves area and plant height of tomato. The early and total yield of tomato per plant significantly increased by decreasing the plant density from 6 to 4 and 2 plants /m2. On the contrary, the highest total yield per m2 was given by tomato density 6 plants. Tilapia average weight of (g), tilapia total yield (Kg/m3), average daily gain (ADG) and specific growth rate % (SGR) results increased significantly by increasing the plant density of tomato from 2 and 4 up to 6 plants / m2. Increasing the tomato plant density led to decrease significantly NO3, P, K, Ca and Mg (ppm) values of fish rare water content during the season period due to increasing the removal of nutrients for tomato sake. The accumulation of nutrients in rare fish water increased by increasing the growth of fish tilapia. The highest results of NO3, P, K, Ca and Mg were recorded by tomato plant density 2 plants /m2 while 6 plants /m2 had the lowest nutrient contents.
For sustainable food production, the study recommended the plant density of tomato 6 plants /m2. 18 tomato plants in 3 m NFT system length (6 plants/m2) integrated with 150 tilapia fish in 1 m3.

The Penman-Monteith method (P-M) to estimate the reference evapotranspiration (ETo) is the most reliable method and recommended by the FAO as the standard to verify other empi- rical methods. However, the Thornthwaite (Th) and Hargreaves-Samani (H-S) models are widely used because they are based on measurements of air temperature, frequently recorded in any meteorological stations. In this study, the daily meteorological parameters of air temperature, relative humidity, wind velocity, were available at six stations (Riyadh), (Ha’il), (Tabuk), (Turayf), (Makkah) and (Jazan). The net radiation was computed using a mathematical model based on a serie of related equations. Therefore, the application of Penman-Monteith became possible to calibrate the Thornthwaite and Hargreaves-Samani models. The local calibration of the both models (Th and H-S) in arid conditions is based on modifying the original coefficients of the named models using the ratio for estimated ET (Th and H-S mpdels) and the reference ETo of (P-M model). In the comparison, the indices of concordance (D), confidence (C), correlation coefficient (r) were analyzed, together with the root mean square error (RMSE) and Nash-Stucliff Efficiency (NSE). So, the ET of H-S model without adjustment were greater than the ETo of P-M during all the months at the total of the studied stations. Contrary, the use of non-adjusted Th ET show a smaller values of the monthly average in a total of the selected stations. After adjustment of the original coefficients of (0.0023) for H-S model and (1.6) for the Th model, we can obtain the new equations of estimating the monthly average of ET fitting better with the P-M Eto model.

East Flood Canal is a canal built to handle flooding in the city of Jakarta. In addition to the canal flow as the main element, there are also borders on the left and right of the canal as supporting elements of the Banjir Kanal Timur. The border area of the Banjir Kanal Timur has the potential to be used as a green open space or public open space that helps increase the functional, ecological and aesthetic value of the city. The objective of this study is to provide input to optimize the Banjir Kanal Timur border as a public open space while still prioritizing the hydrological and ecological functions
This research uses rationalistic and descriptive methods. Data was obtained through observation, interviews and theoretical data, established regulations. The research location was divided into several zones to facilitate analysis.
From the results of this study it was found that the boundaries of Banjir kanal Timur can be utilized as a shared public green open space. The existing condition of its land use is still not optimal, does not have adequate facilities and infrastructure as a public area with recreational activities.
Limitations of the study – From the results of this study it was found that the boundaries of the Banjir Kanal Timur can be mandated as a team or togetherness of public green spaces.
The definition of a community is a social group that shares an environment with each other. This research uses community theory in developing public green open spaces on the banks of the Banjir Kanal Timur through the concept of inclusive landscape design.

Lead Rubber Bearing (LRB) is a passive type of base isolation that can be used as a damper for earthquake vibrations on bridges and buildings. The components that make up the LRB are several layers of rubber laminated to steel plates to increase vertical rigidity. LRB is also reinforced with lead cores to dissipate earthquake energy that enters the bridge structure or buildings. This paper will explain the design and production of LRB and test the results of the analysis. In this design, the properties of the materials used in the LRB are explained, the function of each material, the relationship between the design and the need to absorb earthquake loads on bridge structures or buildings. It also explains the determination of elastomeric thickness and number of layers, size of insulator, elastomer thickness and number of layers, number of rubber layers, total height, vertical and horizontal stability checks. The production method is very important to get a quality LRB product. Production starts from material selection, vulcanization process and quality control. The research was carried out successfully by studying the literature and technical analysis by carrying out several simulations with various dimensions to get better performance. Several developments were made to get better LRB performance. The damping of structures without base isolation is generally +/- 5%. For the need for good performance against earthquake loads, the attenuation can be increased to 20–30%. This is very useful for reducing earthquake loads, when a decrease in building acceleration cannot be obtained in tall buildings with base isolation. Likewise with the dimensions of the lead core. This research is still limited to theoretical analysis and prototyping, because no experiments have been carried out in the laboratory or applied to a construction project

This paper examines groundwater potential zones with the help of remote sensing and GIS methods for controlling and investigating the geospatial data of each parameter. Because of several conditions such as rapid population growth, urbanization, industrialization and agricultural development, groundwater sources are under severe threat. Climate change plays an important role in the quality and quantity of groundwater potential. Unreliable exploitation, poor quality of surface water resources tend to increase the decline in groundwater levels. This study was conducted in the Abbay River Basin, where groundwater serves as the main source for agricultural purposes rather than surface water. Seven selected parameters—lineament density, precipitation, geology, drainage density, land use, slope and soil data—were collected, processed, resampled, projected and reclassified for hydrological analysis. For generation of groundwater zones, weightage was calculated using an analytical hierarchy method. The consistency ratio estimated for this study was 0.089, which was acceptable for further analysis. Based on the integration of all thematic layers and the generated groundwater potential zones, the map was reclassified into five different classes, namely very good, good, moderate, poor and very poor. The results of this study reveal that 1295.33 km2 of the study area can be considered very poor, 58,913.1 km2 is poor, 131,323 km2 is moderate, 18,557 km2 is good and 311.5 km2 is very good. Any groundwater management project performed in the better regions would offer the greatest value. A similar study would be valuable before planning any water resource development activity to save comprehensive field investigations.

Purpose – The purpose of this paper is to investigate the factors influencing the responsiveness of construction participants to building collapse in the Nigerian construction industry. There has been a general type of response to incessant menace of building collapse among construction participants which is, playing the blame game. This is worrisome considering its attendant psychological effect on the affected persons and cost implications to the industry at large. Design/methodology/approach – Literature review conducted identified forty-nine (49) factors that can influence the responsiveness of construction participants to building collapse, which were employed to design a questionnaire survey. Data collected were analysed using descriptive statistics, mean score, Kruskal–Wallis test of ANOVA and multivariate techniques such as factor analysis. Findings – The descriptive and empirical analysis showed disparity of ranking of the 49 factors among the groups studied. There was statistically significant difference (ρ < 0.05) in 35 representing 71.4% of the factors influencing the responsiveness of participants in the construction industry to building collapse while the remaining 28.6% was not significantly different. Therefore, irrespective of the individuality of response from each group of construction participants, they still demonstrated a reasonable level of agreement in their responses to the factors influencing the responsiveness. Among the significant factors based on the mean score rankings are quality of materials, availability of experienced professionals, adequate enforcement of building code, design and specifications changes, financial capability of clients and budget allocation for building projects. Through factor analysis, the study categorized the forty-nine factors influencing the responsiveness of participants in the construction industry into six general factors. The factors are: client related; project procurement related; economic management related; ethical values related; construction management related and policy management related. Practical implications – The investigation into the factors influencing the responsiveness of participants is with a view to mitigating continuous occurrences of building collapse in Lagos State, and Nigeria as a whole. This is a very useful information on the roles and duties of all construction professionals and other stakeholders in the construction industry. Also, stakeholders in the academia can carry out a review of the curriculum for tertiary institutions based on the information on factors influencing responsiveness of construction participants. Originality/value – The study was able to categorise all the forty-nine factors into six basic groups using the factor analysis, and this could be used to develop measures for mitigating occurrences of building collapse. hence, it has successfully provided insightful knowledge base regarding the basic factors influencing the responsiveness of participants in the construction industry to building collapse, especially in Lagos State, Nigeria.

Building growth technology is rapidly recognised at a global level as being a key aspect in the future of construction projects, although construction robotics and automation (CRA) has undergone any major reality deployment to date. Nevertheless, the latest, substantially sustainability requirement is potentially the necessary cause for the larger implementation of construction robotics and automation. There are nevertheless small attempts at the detailed investigation of the effect of using construction robotics and automation on the sustainability efficiency of buildings and construction, but structured advice for the building industry is lacking in this sense. The study in this paper represents the first step towards addressing by analysing and examining the construction robotics and automation techniques and innovations available and for the first time creating a coherent system of metrics for measuring the sustainability efficiency of construction robotics and automation usage in buildings. The ultimate objective of the study must therefore be the creation of a rigorous and consistent methodology for evaluating, within this framework, the feasibility of construction robotics and automation in the construction projects context.
