Making National Building Codes Work

This Commonwealth Association of Architects (CAA) CPD event explores the critical challenges and opportunities in developing, implementing, and enforcing building codes across Commonwealth nations, with particular focus on climate change adaptation and mitigation. Drawing on expertise from the Pacific, Caribbean, Africa, and international organizations, the session examines why many building codes fail to deliver their intended purpose of protecting public health, safety, and welfare, especially for vulnerable populations. The discussion highlights the urgency of effective building codes in the context of rapid urbanization, climate vulnerability, and the projected addition of over 90 billion square meters of floor space in Africa alone over the next 40 years.

Outline 

• Introduction to building code challenges across Commonwealth countries, with survey findings showing 30% of respondents consider their planning policy unfit for purpose and nearly 50% view their building codes similarly
• Pacific region perspectives on outdated codes, enforcement challenges, and the need for regional harmonization (presentations from Fiji, Samoa, and Pacific Region Infrastructure Facility)
• Caribbean experiences examining the regulatory framework, enforcement mechanisms, and the diversity of approaches across island states
• Legal and legislative design perspectives on creating effective, enforceable, and contextually appropriate building codes
• Panel discussion addressing affordability, compliance, enforcement capacity, climate resilience, and the role of international frameworks including the Buildings and Climate Global Forum declaration

Learning Outcomes

The sessions learning outcomes were:

• Understand the scale of the building code challenge globally, particularly that approximately 50% of countries worldwide lack mandatory building codes, with the highest concentration of gaps in Africa where most future construction will occur
• Recognise that building codes cannot function in isolation and must be supported by appropriate legislation, institutional capacity, enforcement mechanisms, professional qualifications, and adequate resourcing
• Appreciate the importance of context-specific standards rather than simply adopting codes from other jurisdictions, ensuring standards are locally appropriate, realistic, and achievable given available resources and capacity
• Identify the critical relationship between building codes and climate action, including the need for updated hazard design parameters (wind speeds, rainfall, sea level rise, seismic data) and integration of energy efficiency, embodied carbon, and resilience measures
• Understand that compliance and enforcement failures often stem from unrealistic standards rather than lack of will, and that codes must be designed with implementation feasibility in mind from the outset
• Learn about regulatory impact assessments as a tool for transparent, evidence-based decision-making that considers costs, resources, political priorities, and stakeholder engagement in building code development
• Recognize the value of regional cooperation and knowledge sharing, particularly for small island states and countries with similar climatic and developmental contexts
• Understand the role of progressive implementation and varying compliance levels as pragmatic approaches to achieving improved safety outcomes while addressing affordability constraints
• Appreciate the importance of bio-based and local building materials in achieving both sustainability and affordability goals, and the need for research, development, and standardisation to support their use
• Recognize that building codes are tools for protection, not exclusion, and must not criminalize vulnerable populations who lack resources to comply but rather facilitate incremental improvement

Core Curriculum Topics

• Design, Construction & Technology
  This session directly addresses how building codes establish minimum technical standards for structural sufficiency, fire safety, health, amenity, and resilience to natural disasters and climate change. It explores the balance between technical excellence and practical deliverability, and the importance of contextually appropriate design solutions.
• Sustainable Architecture
  The session extensively covers climate change mitigation (energy efficiency, embodied carbon, renewable energy integration) and adaptation (resilience to cyclones, flooding, sea level rise, extreme weather events) within building codes. It addresses the urgent need to align building regulations with climate targets and SDG objectives.
• Legal, Regulatory & Statutory Compliance
  The session emphasizes the architect’s role in stakeholder engagement, advocacy for fit-for-purpose building codes, collaboration across disciplines and sectors, and ethical responsibility to protect vulnerable populations. It highlights the importance of contributing professional expertise to legislative and policy development processes.

SDG Learning Outcomes

• SDG 11: Sustainable Cities and Communities
  The session directly addresses Target 11.1 (adequate, safe and affordable housing for all) and Target 11.b (integrated policies for resilience to climate-related disasters). Effective building codes are fundamental to making cities and human settlements inclusive, safe, resilient and sustainable.
• SDG 13: Climate Action
  Building codes are critical tools for both climate mitigation (reducing emissions through energy efficiency and embodied carbon reduction) and adaptation (protecting communities from climate-related hazards). The session emphasizes updating codes to reflect climate change impacts and future climate scenarios.
• SDG 10: Reduced Inequalities
  The discussion addresses how building codes can either protect or exclude vulnerable populations, particularly the urban poor. The session explores strategies to ensure building codes promote equality of outcome rather than criminalizing those who lack resources to comply.
• SDG 9: Industry, Innovation and Infrastructure
  The session covers the need for research and development of local, sustainable building materials (timber, bamboo), innovation in enforcement mechanisms (digitization), and development of resilient infrastructure that can withstand natural disasters and climate impacts.

The following CPD questions forms part of the learning guide for this session. As different Institutions of Architecture across the Commonwealth have different CPD reporting requirements, it is suggested that you retain a copy of your responses to these questions for your records.

1. Climate Resilience: How can building codes in your jurisdiction better prepare buildings for future climate conditions rather than just current weather patterns?
2. Sustainable Materials: What role should building codes play in encouraging the use of locally-sourced, low-carbon materials in your region?
3. Implementation Reality: Are the building codes you work with realistic and achievable for all sectors of society, or do they inadvertently exclude vulnerable populations?
4. Professional Advocacy: How can architects contribute to making building codes more effective, both in their development and in their enforcement?
5. Energy and Carbon: What additional provisions related to operational energy efficiency and embodied carbon should be prioritised in building code updates?
6. Regional Collaboration: What opportunities exist for knowledge sharing and harmonisation of building standards with neighbouring countries facing similar climate challenges?
