The push for net zero carbon is changing building materials and systems. What are the fire safety implications?. Net Zero and Fire Safety The UK's commitment to net zero by 2050 is driving fundamental changes in building design that affect fire safety. Fire Safety Considerations Increased insulation — greater fire load in external walls Timber construction — combustible structural systems Solar PV panels — rooftop fire and firefighter access risks Battery storage — lithium ion thermal runaway Heat pumps — refrigerant leak risks Natural ventilation — impact on smoke control Green roofs — fire spread through vegetation For sustainable fire engineering, contact us.
