Green Fire 2.0 — Sustainable Fire Protection and Resilient Facilities For a facility to be truly sustainable, it needs to be fire resilient. Walker Fire Protection introduced the Green Fire concept more than 20 years ago, applying environmentally sustainable principles across the lifecycle of fire protection systems. Green Fire 2.0 builds on those principles, addressing both the environmental impact of fire protection and the role effective systems play in protecting facilities, resources and embodied carbon. Today, the sustainability landscape has broadened considerably. Net zero emissions, embodied carbon, circular economy principles, electrification and building resilience are increasingly influencing how facilities are operated and renewed. At the same time, electric vehicles (EVs), battery energy storage systems (BESS), photovoltaics and alternative construction materials are changing the fire risk profile of the built environment. FLEXIBILITY | ADAPTABILITY | DURABILITY | MAINTAINABILITY This Advisory Note introduces Green Fire 2.0 and considers the relationship between sustainable fire protection and facility resilience.
1. Conserve Water Fire sprinkler and hydrant systems can discharge significant quantities of potable water through routine testing, maintenance and modifications. Water capture or recirculation, localised isolation, appropriate control valve arrangements and technologies that minimise sprinkler system drain-down can substantially reduce water consumption. Localised isolation can also reduce the extent and duration of system impairment, keeping unaffected areas protected while works are undertaken. 2. Keep Assets in Use for Longer
Fire Resilience is Fundamental to Sustainability
Circular economy principles are highly relevant to fire protection.
The environmental impact of a fire extends well beyond the immediate damage to a building.
Where equipment and infrastructure remain suitable, compliant and capable of performing their required function, consider maintaining, repairing, refurbishing or retaining them rather than automatically replacing them.
A significant fire can result in the loss of building materials, equipment and contents, waste sent to landfill, the consumption and contamination of firefighting water, business interruptionand, ultimately, the manufacture, transport and installation of replacement materials. Research undertaken by FM Global and the Home Fire Sprinkler Coalition has demonstrated that effective sprinkler protection can significantly reduce fire damage, greenhouse gas emissions, firefighting water consumption and contaminated water runoff. This highlights an important Green Fire 2.0 principle: sustainability should consider not only the environmental footprint of fire protection, but also the resources and embodied carbon that effective fire protection helps preserve.
The Facility Manager’s Sphere of Influence Facility managers have considerable influence over these outcomes through the way fire protection systems are operated, tested, maintained, modified and renewed.
This applies to individual equipment as well as existing pipework, cabling, detection systems, pumps and other infrastructure during refurbishment and tenancy works. Procurement decisions should consider a facility’s “whole-of-life and environmental impacts,” not simply the lowest immediate replacement cost. 3. Reduce Carbon and Material Impacts Manufacturing, transportation, installation, operation, maintenance, replacement and disposal all contribute to the lifecycle carbon impact of fire protection assets. Associated emissions that may fall within an organisation’s Scope 1, Scope 2 or Scope 3 emissions. Retaining serviceable infrastructure, extending equipment life, reducing unnecessary modifications, selecting durable products and using remote monitoring where appropriate can reduce these impacts.
Green Fire 2.0 – Sustainable Fire Protection and Resilient Facilities Importantly, these impacts should be considered against the potentially much greater carbon and material consequences of rebuilding following a major fire.
6. Maintain the Strategy – Not Just the Assets
4. Design Today’s Changes for Tomorrow
Facility managers should maintain access to current fire engineering reports, system documentation, interfaces and commissioning information, while considering significant building modifications in the context of the overall fire strategy.
Facilities continually change through tenancy alterations, refurbishments, technology upgrades and changes in use. Appropriate zoning and control valves, flexible sprinkler arrangements, accessible isolation points and provision for foreseeable future changes can reduce material use, water loss, system impairment and rework over the life of the facility. Design today’s fire protection solution so that it does not unnecessarily create tomorrow’s waste. 5. Manage the Fire Risks of the Net Zero Transition EV charging, battery storage, photovoltaics, electrification and alternative construction materials can introduce new or changed fire hazards, often long after the building’s original fire safety strategy was developed. Facility managers should ensure the existing fire safety strategy is reviewed where significant sustainability or electrification upgrades are proposed. This may include considering the adequacy of existing sprinkler protection, detection, fire water supplies, smoke management, compartmentation and emergency response arrangements. This is particularly important in buildings incorporating Performance Solutions or measures documented in a Fire Engineering Report, where fire safety measures may form part of an interconnected strategy based on assumptions made when the building was originally designed. Fire safety professionals should be involved early so that sustainability objectives and fire safety requirements can be considered together. A net zero initiative that inadvertently reduces the fire resilience of a facility is not a sustainable outcome.
Maintaining individual fire systems does not necessarily ensure that the overall fire safety strategy remains effective as a facility changes.
Good asset information and an understanding of system interactions can improve reliability, reduce unnecessary investigation and replacement and prevent modifications from inadvertently compromising fire safety.
Green Fire 2.0 Twenty years on, the original Green Fire principles of flexibility, adaptability, durability and maintainability remain highly relevant. What has changed is the context in which they are applied. Green Fire 2.0 integrates fire safety, sustainability, circularity and resilience throughout the operational life of a facility. For facility managers, the opportunity is practical: use less water, keep assets in service longer, reduce unnecessary material use and carbon emissions, plan for change, understand emerging risks and protect the integrity of the facility’s fire safety strategy. For a facility to be truly sustainable, it needs to be fire resilient.

GREEN FIRE IN PRACTICE Small changes in the way existing fire systems are managed can produce measurable sustainability benefits. Dropmaster™ is a sprinkler head replacement system that removes trapped water through patented siphoning. This avoids the spills, water damage and clean-up that would otherwise result from draining the system, while also reducing labour time. Zoned control valve arrangements allow localised isolation and drain-down instead of requiring an entire system to be drained. This reduces water waste while keeping unaffected areas protected. Water capture or recirculation systems can conserve significant quantities of potable water that would otherwise be discharged during routine fire system testing.
