The Building Safety Act 2022 introduces a new framework for regulating high-rise residential buildings, with a focus on accountability, competence, and transparency. The Act establishes a new Building Safety Regulator to oversee the design, construction, and management of high-rise buildings, and imposes stricter requirements on developers, building owners, and contractors. The UK system is moving towards a more centralized and prescriptive approach to building safety, driven by the need to restore public confidence in the safety of buildings.

2.3 European Union:

The European Union promotes harmonization of building safety standards through directives and regulations, such as the Construction Products Regulation (CPR). The CPR sets out essential requirements for construction products, including mechanical resistance and stability, fire safety, hygiene, health, and the environment, safety and accessibility in use, protection against noise, and energy economy and heat retention. While the EU provides a framework for harmonizing building safety standards, member states retain considerable autonomy in implementing and enforcing these regulations. This can lead to variations in building codes and enforcement practices across the EU.

2.4 Australia:

Australia utilizes the National Construction Code (NCC), which is developed by the Australian Building Codes Board (ABCB). The NCC sets minimum performance requirements for buildings, covering aspects such as structural integrity, fire safety, accessibility, and energy efficiency. The NCC is adopted by each state and territory, with some variations to address local conditions. The Australian system emphasizes performance-based regulation, allowing for flexibility in design and construction while ensuring that buildings meet minimum safety standards.

2.5 Japan:

Japan has a highly developed building safety regulatory framework, characterized by stringent seismic design requirements and rigorous enforcement. The Building Standards Law (BSL) sets out minimum requirements for building design and construction, with a strong emphasis on earthquake resistance. Japan’s building codes are regularly updated to incorporate the latest scientific knowledge and technological advancements in earthquake engineering. The Japanese system also places a strong emphasis on quality control and independent inspection to ensure compliance with building codes.

2.6 Synthesis:

These diverse approaches to building safety regulation reflect different priorities and historical experiences. The US system emphasizes flexibility and local control, while the UK is moving towards a more centralized and prescriptive approach. The EU promotes harmonization through directives and regulations, while Australia utilizes performance-based regulation. Japan places a strong emphasis on earthquake resistance and rigorous enforcement. A key difference is the approach to liability. Some jurisdictions, such as the UK, are increasingly focused on holding individuals accountable for building safety failures, while others rely more on organizational accountability and professional standards.
