Abstract

In order to ensure the health and safety of occupants, buildings must be inspected to check their compliance to current regulatory requirements prompted by occupancy changes, renovations and building code revisions. Recent inspections conducted by Public Works Canada have identified about 1700 occurrences of code violations in 19 buildings. There is an enormous amount of information that can be extracted from the study mentioned above to implement a knowledge‐based expert system to assist in future building inspections. The philosophy of this expert system is to integrate both knowledge‐based and hypertext representation techniques to enable building inspectors to quickly identify code violations, refer to the code text and provide case study information that can assist in resolving a problem. The present paper describes the development framework and details of a prototype implementation known as the Health and Safety Expert System (HASES). The HASES currently addresses the requirements of ‘Section 3.4: Requirements for Exits’ of the 1990 National Building Code of Canada. The software architecture consists of an external database of building details, an object hierarchy and a rule‐base representing the code requirements, hypertext user‐interface for code text and case study information. The ultimate objective is to make this system available for field inspections using notepad computers.

Abstract

A game‐theoretic model of moral hazard associated with unobservable builder effort is postulated to examine the effectiveness of homeowner warranties and building code enforcement by local government in assuring desired builders’ effort. Builders have an incentive to claim and charge for high unobservable effort level in constructing homes, but actually exert low effort to earn higher profits. We find that a homeowner warranty increases the unobservable effort of the builder, but cost minimizing behavior by the builder results in an effort choice less than the most efficient level. On the other hand, building code enforcement essentially converts unobservable builder effort to observable effort and efficient effort is indeed possible if enforcement cost is justifiable. However, an overly strict building code may be detrimental to buyers. The conditions under which a buyer would prefer one alternative over the other and where both measures can co‐exist are also examined. The model provides several interesting implications and testable hypotheses. A survey of builders and building codes provides preliminary evidence to support the proposed model.

Abstract

Purpose

The purpose of this paper is to propose building code changes that would benefit both architectural design and the potential of achieving nearly zero energy goals by analyzing the architectural implications of the energy system boundaries within the Swedish code.

Design/methodology/approach

The analysis is driven by three questions that relate the national implementation of EU directive on nearly zero energy 2020 to the premises set out in the guidelines for revising the Swedish building code aiming at a performance-based regulation. A crucial part of the research is a comparative analysis of the design implications of the code to research findings in scientific articles on near-zero energy or low-energy design.

Findings

The energy system boundaries in the Swedish code are steering the architectural design and energy consequences of offices towards using less heat but more electricity. The energy section is also limiting the architectural design choices by ignoring the positive energy aspects of daylight. A proposal of a new comprehensive energy section taking all architectural design related energy aspects into account is presented, in order to support design of nearly zero energy buildings.

Practical implications

A building code that relates the energy system boundaries to form will help integrated design choices that are more likely to support the strive towards nearly zero energy buildings.

Originality/value

The paper reveals the design implication of the Swedish energy section to be counterproductive regarding energy efficiency as well as limiting architectural design choices.

Abstract

Purpose

The New Zealand building code has played a vital role in reducing the impact of disasters in the built environment. Following the nature of earthquake occurrences, the associated impacts such as building collapse and the increase in technological innovation in the building sector, the New Zealand building code has been frequently amended. The building code amendment ensures that buildings and other related infrastructures can withstand the impact of ground shaking without substantial damages to buildings. The purpose of this paper is to identify and explore the benefits of building code amendments in New Zealand.

Design/methodology/approach

Document analysis and closed-ended questionnaire were adopted as data collection instruments for this study. The relevant stakeholders comprise structural engineer, geotechnical engineer, architect, building services consulting engineer, licensed building practitioner, project manager, building contractor, local authority, academic/researcher and quantity surveyor.

Findings

A significant proportion of the survey participants that agreed to the importance of building code amendments in New Zealand justify the benefits of the amendments. The study serves as a useful guide to policy regulators and researchers who are exploring other aspects of regular building code amendments in New Zealand. The findings from this study suggest that amending the New Zealand building code needs a proactive approach to promote local technology, enhance low-cost construction materials, training of code users and reducing bureaucracy in design approval and construction inspection. The study concludes that improving on the 28 factors identified in this study would contribute intensively to disaster risk reduction in the built environment and an increase in compliance level in New Zealand.

Originality/value

This paper originality comes from its practical approach towards identifying the benefits of building code amendments

Abstract

Purpose

New Zealand building code may be serving its purpose to an extent, there is still a need to develop a framework to improve the use and application of building code for better building performance and services. This study aims to validate the identified parameters in the developed framework to improve building code practice in New Zealand.

Design/methodology/approach

Subject matter experts interview was conducted with key stakeholders that use building code, standards and other associated compliance documents.

Findings

The findings from this study establish the importance of improving the building code, and the efficacy of validated framework helps to identify the areas with the most pressing needs within the building regulatory system. All the subject matter experts unanimously agreed on educating and training the building code users. Besides, the validated framework will enable the policy decision-makers in the building regulatory system to promote the use of building code and the utilisation of its potentials in reducing disaster while increasing the built environment resilience. The study concludes that the designed framework will create more robust strategy implementations to enhance innovative solutions embedded in performance-based building code.

Originality/value

This study originality centres on the practical application of an evidence-based framework for performance-based building code, standards and other related compliance documents.

Abstract

Purpose

The process followed in amending building code creates problems for code users within the building industry. These problems include the need and frequency of changes made to building code, access to updated documents, method of communication, amendment interval and amendment pathway. This study aims to explore the viewpoints of building code users regarding building code amendments in New Zealand.

Design/methodology/approach

Using a closed-ended questionnaire survey, this paper examined the New Zealand building code amendments by evaluating the views of experienced and relevant stakeholders within the research area.

Findings

A high proportion (50.90%) of the survey participants agreed to a three-years building code amendment cycle, as against the current biannual Amendment practiced in New Zealand. Findings from the study affirmed the necessity for building code amendment and the support for free amended building code documents to the public and other building standards. The study concludes with strong support to the use of intensive research and learning gained from disasters in building code amendment in New Zealand. Implementing the code users opinions encourages disaster resilience through effective application of the building code requirements in design and construction.

Originality/value

The contribution from this study offered a unique insight into the perspectives of building code users on building code amendment in New Zealand and ways of incorporating the findings in the building code later updates to improve disaster resilience in the built environment.

Abstract

Purpose

The paper deals with the challenges and opportunities of enabling resilience of the built environment through building regulations and codes in a developing country context. The purpose of this paper is to explore how voluntary compliance can be achieved, drawing from the views of key stakeholders in this field.

Design/methodology/approach

Dhaka, the capital city of Bangladesh, is a central hub of more than 20 million people. The city is growing rapidly in an unplanned manner to host the increasing population, creating vulnerability to different hazards including earthquakes, fires and building collapses. The Bangladesh National Building Code (BNBC) and the building and planning regulations of the Capital Development Authority are the key instruments for ensuring safety, but lack of compliance is widespread. The views of relevant stakeholders on issues relating to compliance of safe building codes for ensuring disaster resilience were documented and analysed.

Findings

It was found that those involved in construction activities are in most cases not aware of the BNBC; landowners were reluctant to follow regulations and codes to avoid extra cost; and construction workers were not interested in compliance as there were no incentives. While enforced deterrence is required, it has its limitations in a context such as Dhaka. Raising awareness and building capacity at all levels can offer a way forward for voluntary compliance. Incorporation of knowledge on regulations and codes for disaster resilience into university and technical education curricula are likely to allow developing the capacity of built environment professionals and widespread awareness can be raised through training, media and public events.

Originality/value

There are many publications on building regulations and codes, but few specifically focussing on disaster resilience. Also, much of the discussion on regulations and codes deals with compliance through enforcement, but hardly any deal with the idea of voluntary compliance. There are also a lot of publications on disasters in the case study city, Dhaka, but comparatively few on building codes and regulations specifically for disaster resilience.

Abstract

Purpose

This research informs the intersection of climate and heritage policy development by examining the history of US energy policy as it relates to historic buildings, emerging policy tools to reduce greenhouse gas emissions, and the implications of a changing legislative landscape on historic buildings through the case of New York City.

Design/methodology/approach

This study employs a multi-method approach, including a review of US energy codes; discourse analysis of government records, energy studies, and reports related to historic buildings and energy; select research into energy-related heritage policy at the municipal level; and geospatial and statistical methods to analyze policy implications in the case study of New York City.

Findings

Historic buildings have long been afforded exemptions from energy code compliance in the US, and these waivers are widespread. Contemporary operating energy and greenhouse gas data, as well as energy justice findings about whom these waivers privilege, challenge these exemptions and signal a need for significant policy reform in light of climate change.

Originality/value

This study questions longstanding rhetoric about historic buildings being inherently green and supports the need for more evidence-based research to undergird heritage policy reform that is equitable and climate-responsive.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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

Research limitations/implications

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.

Practical implications

This study would help enhance disaster governance in developing nations.

Social implications

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

Originality/value

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.

Abstract

Relates how partnering between public and private participants can transform the process of obtaining construction permits and ensuring building code compliance into a co‐operative pursuit of common objectives. States use of partnering techniques between the Department of Inspections, Licenses and Permits (DILP) of Howard County, Maryland, and The Johns Hopkins University Applied Physics Laboratory (APL), a large research facility in Howard County. Argues that experience in designing and setting up a partnering process for building code compliance may be of interest to anyone with a large campus and a need to reconfigure and renovate space regularly; as well as to local officials responsible for monitoring building code compliance for such facilities: for example, large corporate and manufacturing facilities, hospitals, or college and university campuses.
