Single-family houses in Vancouver that were built prior to 1940 are a cache of wood from British Columbia (BC) old-growth forests. The purpose of this paper is to discuss the environmental and heritage values of maintaining this finite resource, assess the current policy and regulatory efforts of the City of Vancouver to save this resource and recommend further opportunities to improve and expedite these efforts.

Using the City of Vancouver as a case study, this paper identifies effective policy practices to encourage and facilitate salvaging and reusing old wood resources. Additionally, the paper discusses the key challenges and risks that need to be addressed for these policy approaches to succeed.

Pre-1940 houses constitute about 40 percent of single-family houses that have been demolished in Vancouver in the past few years. The City of Vancouver enacted the Green Demolition Bylaw in 2014 requiring a minimum of 75 percent diversion of demolition waste. However, wood from these houses has been mainly chipped and recycled as biomass fuel or landscape mulch rather than reused. The result shows that regulatory enforcement along with support for infrastructure development may be crucial to protect the remainder of this valuable heritage resource.

This paper considers the environmental and heritage values of wood elements used in old houses and recommends further policy and regulatory interventions to maximize wood salvaging and reuse. Since protecting entire houses may not be always feasible, retention of wood elements is proposed as an alternative path for maintaining and cherishing this ancient and irreplaceable heritage.

This paper asks what was the state of building-code enforcement and citizen – government collaboration in disaster preparedness when an earthquake hit Kathmandu metropolitan city (KMC) in 2015? It reviewed government documents, analyzed media reports, interviewed building-code monitoring officers and carried out a detailed case study of the earthquake-damaged Park View Horizon Housing Apartment (PVHA) Complex. The research found several earthquake-resilience issues. They were enforcement-vulnerability (Building bylaws, planning permit and building code); institutional-coordination vulnerability; Apartment-regulation vulnerability; technological vulnerability; and citizen-government-collaboration vulnerability.

The study area of this research is KMC, and this research is based on content analysis, field observation and interview. It has reviewed all the newspapers and media reports that had covered earthquake issues during and after the 2015 disaster, as well as the articles published in Nepal, South Asia, the USA, New Zealand and Haiti. The literature on Nepal’s building code, seismic history and institutional arrangements for governing earthquake-related issues were reviewed. After field observation of some of the damaged apartments, a detailed case study of PVHA Complex was carried out.

The research found several earthquake-resilience issues. They were enforcement-vulnerability (Building bylaws, planning permit and building code); institutional-coordination vulnerability; Apartment-regulation vulnerability; technological vulnerability; and citizen-government-collaboration vulnerability

A limitation of this study was its heavy reliance on content analysis, one case study and a few interviews and discussions with affected residents, local governments and developers.

This study would help enhance disaster governance in developing nations.

The citizen–government collaborative approach to earthquake resilience would enhance human resilience to disaster at individual and community levels.

Since this is the first research carried out on the state of building code and institutional resilience at the time of the 2015 earthquake in Nepal, it is original and provides policy insights for earthquake resilience in Nepal.

The purpose of this paper is to investigate the barriers inhibiting the adoption of green building and measures to promote this approach in Pakistan.

Barriers and measures were identified and examined by using a combination of research methods, including literature review, questionnaire survey, and in-depth interviews with the construction industry-related practitioners working in Pakistan. Ranking technique and factor analysis were used to identify the significant issues associated with the adoption of green building practices.

As per the survey results, the most critical barrier is “lack of awareness among people about the importance and advantages of adopting green building practices,” followed by “lack of incentives from government” and “lack of green building codes and regulations,” respectively. The results also indicate that most important measure to promote the adoption of green buildings is “creation of public awareness toward green initiatives through seminars, workshops, and discussions,” followed by “availability of green building codes and regulations (mandatory to apply)” and “financial incentives and penalties by the government (e.g. soft loan, tax) for promoting green building practices,” respectively.

Research limitation is that its findings, other than Pakistan, cannot be generalized to other developing countries.

Findings of the research will be helpful in sensitizing the regulatory agencies, the policy makers, and the building construction practitioners about the barriers to adoption of green building practices. The suggested measures will help in devising policies and economic measures to promote the construction of green and environment-friendly buildings.

This research will help the common people to know about the importance of green buildings that may lead to a deviation from the practice of traditional buildings to a widespread trend of building green buildings. This will lead to drastic reduction in demand for energy and considerable monetary savings for the common people.

The findings of this study are expected to contribute valuable information to decision makers for the better understanding of key issues that call for more attention in the promotion of efforts of green building practices in Pakistan. The results are based on the perception of local stakeholders, but might also be helpful for policy makers in other countries.

Constant change in current market and social conditions has triggered the demand for a more adaptable building stock. The capacity to assume and accommodate change has thus become a new requirement for buildings. At the same time, there is a growing demand for more environmentally conscious buildings. New protocols, building codes, and certification systems are becoming stricter regarding buildings’ CO2 emissions, energy efficiency, and other environmental aspects. The current building industry fails to satisfy these two demands; conventional buildings rarely enable change, unless undergoing complex renovations, and rarely consider environmental features beyond mandatory legislation. In this context, this paper proposes Modular Ecotechnological Architecture as a response to both demands. The basis is an integrated design that looks at energy, water, and materials’ efficiency altogether, combined with a modular industrialized building system. The system allows buildings to grow or reduce in size according to their needs, with little impact for their inhabitants, enabling versatility for a variety of uses within the same space and over time. This paper presents the concept of this new building system together with the technical, building code-related, and economic challenges encountered throughout recent experimental projects.

In the rapidly urbanizing Indian cities, large buildings are being built demolishing old buildings often with historic, cultural and architectural merit bringing the conflict between development and conservation. In Kolkata, the authority has taken a unilateral decision to construct high-rise buildings demolishing a hundred-year old Bow Barracks housing complex. The purpose of this paper is to present a research study that empirically explored the appropriateness of the policy decision and a recommendation for appropriate development based on the research result.

The design of the research is formulated on the survey method that encompasses observation, interview and collection of data through questionnaire, and survey, documentation and testing of architecture. All findings are analysed; research question and hypothesis are tested with validation.

The research has found that the old housing is of cultural heritage and use value, and the inhabitants are a very special community in Kolkata. The new development proposal in terms of space generation and cost involvement over the benefit of conserving the existing housing is not beneficial. Therefore, the decision of the local body, in terms of value for money, architecture, culture, heritage and sustainability is not proper.

Such a research exploring the benefit between development and conservation for choice of appropriate path of development in managing the development of a city in global south stands for its uniqueness.

The construction industry struggles in environmental and economic performance due to waste generation. Several studies have measured this waste in the construction industry of developing countries like India, Brazil, China, Nigeria and Iran, and proposed strategies to enhance the overall efficiency. But no such work exists in Pakistan's context. The construction industry of Pakistan contributes significantly to the country's gross domestic product (GDP). And with several mega projects in progress to overcome the energy crises and improve the infrastructure of the country, the absence of proper waste management policies and plans calls for empirical research. Therefore, this study quantifies and benchmarks material waste in the local context, its impact on project cost and the effect of multiple subcontracting arrangements on waste generation. It also proposes a conceptual waste management plan (WMP) for local conditions which can be generalized for developing countries.

This paper uses a mixed research approach by leveraging Saunders's research onion model. To benchmark the current wastage practices, quantitative data of material waste in the Pakistani construction industry are gathered through document review of accounting systems, inventory and payment records of 40 completed building projects. Using the data, the waste rate of different materials is measured along with their impact on cost. Additionally, the role of subcontracting arrangements in waste generation is also investigated. Also, semi-structured interviews are conducted with project managers of high- and low-performing construction organizations to propose a conceptual WMP for the local industry and developing countries.

The highest wasteful materials by quantity are wood, sand and concrete blocks, and those by cost are wood, bricks and steel. By quantity, 123% more material was used on average than the actual productive work. Also, the labor only (L-O) subcontracting arrangement causes maximum waste. Moreover, the difference between the highest (155%) and lowest wasting company (104%) is 51%, highlighting the proactive and resistive waste management culture and approach by the worst- and best-performing companies. Further, the impact of waste quantities is more than 2% of the project cost. Finally, a conceptual model consisting of measures at the project, industry and national levels is also proposed as a guide for developing countries.

The findings of this benchmarking study can help improve the project planning, execution and monitoring, and control practices by providing a better understanding of the material waste potential. This will help economize the construction industry and improve its sustainability.

This is the first benchmarking study that quantitatively measures material waste in the construction industry of Pakistan. It highlights that costly as well as sustainability-implicating materials are frequently wasted in the local construction projects. Also, this study correlates the wastage with subcontracting arrangements. Additionally, an original conceptual WMP is proposed that could help the industry improve its performance. The findings could help the construction professionals identify the loopholes in their material management practices and not only save money but also ensure better sustainability.

This paper aims to establish a baseline for carbon dioxide (CO₂) emissions quantification in the current residential construction process. Opportunities to reduce the environmental footprint of the homebuilding process are also identified.

CO₂ emissions of various house construction stages are quantified and utilised in a 3D building information model. This allows rapid emission computations for various house sizes, designs and materials. An intelligent database calculates emissions for different house styles with different construction processes.

Two construction stages (basement walls foundation and framing) were identified as high CO₂ emissions contributors. In addition, equipment operation on site, transportation to and from the site and heating for curing concrete were identified as the main sources of emissions during construction.

The paper addresses the limited attention given to CO₂ emissions during the actual construction process. The introduction of building information modeling for quantifying emissions in the construction process is of significant value. This research is pertinent to the international homebuilding industry and homebuyers who all have a role in mitigating CO₂ emissions.

The paper presents an altered viewpoint of energy renovation means for residential buildings in the built environment.

The paper presents a novel approach for building owners to renovate a building in terms of improved performance, energy efficiency and indoor comfort in combination with planned renovations/refurbishments.

This paper aims to analyse the extent to which privatising – or denationalising land – has legal and policy effects.

It applies the law in context scholarship to the question of land privatisation.

Of all the recent privatisations in England, the most valuable, and yet least recorded, is of land. According to one estimate, two million hectares or 10 per cent of the Britain landmass, left the public sector for private ownership between 1979 and 2018. Privatisations include land that is sold, leased or where a public body changes its status. This paper aims to explore these privatisations, considering them as denationalisations, concluding that the effects are most significant in housing where the differences between social and private renting in relation to rents, the security of tenure and housing quality are striking. Moreover, although other public law restraints on the state-owned property are often limited, they are also still significant, facilitating scrutiny, particularly in combination with the public sector equality duty or site-specific duties for libraries, allotments or playing fields. All the sites disposed of to private developers, landlords and companies have lost these protections.

This is the first time this question has been considered in this way from a legal perspective.
