For a moment, it seemed that the architect had disappeared from the construction supply chain for sustainable and affordable housing provided by Dutch housing associations. Large contractors were making direct agreements with housing associations and wanted to scale up production with their housing factories. However, with the ‘So You Think You Can BUILD’ challenge, architects, consultancies, and contractors reinvented themselves within the construction supply chain and acquired a position as providers of circular building concepts. The aim of this challenge is to stimulate providers of homes to design and produce (in great numbers) affordable and sustainable houses. This not only scales up building production in empty fields but also within difficult and dense build urban areas. A whole new generation of Dutch architects, consultancies, and contractors working in collaboration are now intensively involved with circular and biobased residential buildings, innovative materials and production processes. They are managing to provide attractive products for housing associations and other clients. In the first part of 2021, ‘So You Think You Can BUILD’ challenged teams of designers, engineers and contractors to develop new concepts, with the three winners applying the principles of the ‘passive house’, which is modular and circular, as well as a smart building skin and smart core with open floor space in between.

"The importance of affordable housing has emerged recently due to the suffering of most urban areas and developing countries in particular from the high rates of population growth and migration to cities, in addition to the conditions of poverty and war, which led to the loss of many families for their housing units. (The need for a comprehensive knowledge framework clarifying the concept of affordable housing, choosing the best housing type and cost reduction factors (facilitation aspects) at the local level in light of the country’s urgent need for affordable housing.) Accordingly, the objective of the research was to: (Provide a comprehensive knowledge framework that clarifies the concept of affordable housing and choose the best housing type and cost reduction factors (facilitation aspects) in accordance with local privacy). The research hypothesis : (The factors and means of reducing housing costs (aspects of facilitation mentioned in the research) at the two levels (housing complex and housing unit) as well as choosing the housing style (vertical or horizontal) a role in achieving the principle of affordable housing and solving a large part of the housing crisis. For the purpose of solving this problem, three phases were identified, including the construction of a theoretical framework, which included (4) vocabularies (characteristics of affordable housing, cost-raising factors, cost reduction factors, and dimensions of affordable housing). This is followed by the application of these vocabulary by electing two local samples. The extent of facilitation and comparability between them. The results showed that the vertical building pattern (residential buildings) is characterized by its lack of large areas of residential land, thus it is characterized by being less expensive than horizontal construction. This does not prevent investors from building high-quality residential towers targeting the rich."

Economic growth in ASEAN countries encourages significant urbanized growth. In line with the growth of urbanization, large swathes of residential buildings have been constructed in urban areas, especially, in the case of Indonesia, through the government's 1000 rusun (high-rise affordable housing) development program in Jakarta. In order to reduce energy consumption and create a sustainable rusun, a passive strategy is needed in the form of natural air conditioning through optimized natural ventilation in these buildings. In this study, testing was conducted on Rusun Rorotan in Jakarta, from two wind source directions (north and northwest) with five void decks configuration samples each, in order to determine wind flow and wind speed patterns in the Rusun area. For this purpose, the wind tunnel simulation method using the Butterfly plugin in Grasshopper was employed. T These results should provide a reference for future residential property developers, especially in the scope of other countries in ASEAN, which have similar climatic conditions to that of Indonesia.

Increasing the energy efficiency of the housing stock has been one of the largest challenges of the built environment in the Netherlands in recent decades. Parallel with the energy transition there is an ongoing revaluation of the architectural quality of pre-war residential buildings. In the past, urban renewal was traditionally based on demolition and replacement with new buildings. This has changed to the improvement of old buildings through renovation. Housing corporations developed an approach for the deep renovation of their housing stock in the period 1995–2015. The motivation to renovate buildings varied, but the joint pattern that emerged was quality improvement of housing in cities, focusing particularly on energy efficiency, according to project data files from the NRP institute (Platform voor Transformatie en Renovatie). However, since 2015 the data from the federation of Amsterdam-based housing associations AFWC (Amsterdamse Federatie Woningcorporaties) has shown the transformation of pre-war walk-up apartment buildings has stagnated. The sales of units are slowing down, except in pre-war neighbourhoods. Housing associations have sold their affordable housing stock of pre-war property in Amsterdam inside the city’s ring road. The sales revenue was used to build new affordable housing far beyond the ring road. This study highlights the profound influence of increasing requirements established by the European Energy Performance of Building Directive (EPBD) and the revised Housing Act of 1 July 2015, for the renovation of the pre-war housing stock. The transformation process to climate-neutral neighbourhoods inside the ring road is slowing down because of new property owners, making a collective heat network difficult to realize; furthermore, segregation of residents is appearing in Amsterdam.

High residential living in Malaysia has not been widely given a significant emphasises in literature despite its increasing scale and significance in the real estate market. The significance of high rise is mainly due the increasing rate of migration from rural to urban. It is estimated a total of 77.2 percent of the Malaysian population lived in urban areas in 2020. Approximately, 30 percent of this urban population lives in strata housing. These percentages are predicted to continue to increase in the future. The emergence of high residential building has been argued as confronting various problems which has considerable impact on this life style. Satisfaction is an important outcome of living in one’s dwelling, although it is not the only consideration. High residential building in Malaysia encountered numerous problems in term of management aspects, legislation aspects, and residents’ satisfaction. The purpose of this paper is to investigate the tenants’ satisfaction living in high residential buildings in Klang Valley. The questionnaires survey is conducted amongst 276 tenants at low cost and medium cost HRB using random sampling in HRB located at areas under jurisdiction Dewan Bandaraya Kuala Lumpur (DBKL), Majlis Bandaraya Subang Jaya (MBSJ), Majlis Bandaraya Shah Alam (MBSA), Majlis Bandaraya Subang Jaya (MBSJ), Majlis Perbandaran Selayang (MPS) and Majlis Perbandaran Ampang Jaya (MPAJ). The result from this study shows that tenant in medium cost residential building are more satisfied in term of facilities and management as compared to tenants in low cost residential building. Tenants also not disclosed to the existing act and procedure related to high residential building. In conclusion, this study suggested the Local Authority to emphasise the role of tenant. These recommendation hopefully will increase the level of satisfaction amongst the residents in HRB.

Abstract Background There has been greater recognition of the importance of country ownership in global health and development. However, operationalising country ownership to ensure the scale up and sustainability of proven interventions remains elusive at best. To address this challenge, we undertook a thematic analysis of interviews collected from representatives of local governments, public health systems, and communities in poor urban areas of East Africa, Francophone West Africa, India, and Nigeria, supported by The Challenge Initiative (TCI), aiming to rapidly and sustainably scale up evidence-based reproductive health and family planning solutions. Methods The main objective of this study was to explore critical elements needed for implementing and scaling evidence-based family planning interventions. The research team conducted thematic analysis of 96 stories collected using the Most Significant Change (MSC) technique between July 2018 and September 2019. After generating 55 unique codes, the codes were grouped into related themes, using TCI’s model as a general analytical framework. Results Five key themes emerged: (1) strengthening local capacity and improving broader health systems, (2) shifting mindsets of government and community toward local ownership, (3) institutionalising the interventions within existing government structures, (4) improving data demand and use for better planning of health services, and (5) enhancing coordination of partners. Conclusion While some themes feature more prominently in a particular region than others, taken together they represent what stakeholders perceive to be essential elements for scaling up locally-driven health programmes in urban areas in Africa and Asia.

Without decarbonizing cities energy and climate objectives cannot be achieved as cities account for approximately two thirds of energy consumption and emissions. This goal of decarbonizing cities has to be facilitated by promoting net-zero/positive energy buildings and districts and replicating them, driving cities towards sustainability goals. Many projects in smart cities demonstrate novel and groundbreaking low-carbon solutions in demonstration and lighthouse projects. However, as the historical, geographic, political, social and economic context of urban areas vary greatly, it is not always easy to repeat the solution in another city or even district. It is therefore important to look for the opportunities to scale up or repeat successful pilots. The purpose of this paper is to explore common trends in technologies and replication strategies for positive energy buildings or districts in smart city projects, based on the practical experience from a case study in Leipzig—one of the lighthouse cities in the project SPARCS. One of the key findings the paper has proven is the necessity of a profound replication modelling to deepen the understanding of upscaling processes. Three models analyzed in this article are able to provide a multidimensional representation of the solution to be replicated.

Abstract Chemists find careers in the chemical industry very rewarding. The focus is on applied chemistry and in delivering solutions that meet customer needs, whether the customers are other industrial companies or individual consumers. Chemistry provides solutions to the global challenges facing our society, including the need for clean water, nutritious food, improved healthcare and wellness, affordable housing, and sustainable infrastructure. Within industry, chemists serve in a wide variety of roles. The largest fraction may be in research and development (R&D), although opportunities in manufacturing, technical service and development, supply chain, marketing, intellectual property protection, sales and commercial functions, and many other options are also open to chemists who want to apply their skills [1]. I was drawn to a career in industry because I’m results oriented and I wanted my work to be applied immediately and have an impact.

Building Energy Use

As the population of urban areas continues to grow, and construction of multi-unit developments surges in response, building energy use demand has increased accordingly and solutions are needed to offset electricity used from the grid. Renewable energy systems in the form of microgrids, and grid-connected solar PV-storage are considered primary solutions for powering residential developments. The primary objectives for commissioning such systems include significant electricity cost reductions and carbon emissions abatement. Despite the proliferation of renewables, the uptake of solar and battery storage systems in communities and multi-residential buildings are less researched in the literature, and many uncertainties remain in terms of providing an optimal solution. This literature review uses the rapid review technique, an industry and societal issue-based version of the systematic literature review, to identify the case for microgrids for multi-residential buildings and communities. The study describes the rapid review methodology in detail and discusses and examines the configurations and methodologies for microgrids.

Building Typology

Ongoing urbanization leads to steady growth of urban areas. In the case of highly dynamic change of municipalities, due to the rates of change, responsible administrations often are challenged or struggle with capturing present states of urban sites or accurately planning future urban development. An interest for urban planning lies on socio-economic conditions, as consumption and production of disposable goods are related to economic possibilities. Therefore, we developed an approach to generate relevant parameters for infrastructure planning by means of remote sensing and spatial analysis. In this study, the single building defines the spatial unit for the parameters. In the case city Belmopan (Belize), based on WorldView-1 data we manually define a city covering building dataset. Residential buildings are classified to eight building types which are locally adapted to Belmopan. A random forest (RF) classifier is trained with locally collected training data. Through household interviews focusing on household assets, income and educational level, a socio-economic point (SEP) scaling is defined, which correlates very well with the defined building typology. In order to assign socio-economic parameters to the single building, five socio-economic classes (SEC) are established based on SEP statistics for the building types. The RF building type classification resulted in high accuracies. Focusing on the three categories to describe residential socio-economic states allowed high correlations between the defined building and socio-economic points. Based on the SEP we projected a citywide residential socio-economic building classification to support supply and disposal infrastructure planning.
