Study Notes

Green Construction Overview

Green Construction focuses on energy-efficient and environmentally friendly building methods.
Historical context includes traditional building techniques such as sod-roofed houses and windmills.

Certification Programs

The Leadership in Energy and Environmental Design (LEED) program assesses environmental impact and aims to improve sustainability.
A concern with green certification programs is their often inadequate focus on fire safety.
The International Green Construction Code (2012) was introduced to address fire safety in green buildings.

Materials Used in Green Construction

Bamboo is widely used for furniture, beams, and trusses.
Hempcrete is made from the Cannabis plant’s hurd core, lime, and water.
Green Roofs consist of vegetation and materials that support plant growth, providing insulation.

Risks and Concerns

Green Roofs may pose risks of structural collapse due to added weight and can become combustible without proper maintenance.
Polystyrene insulation is utilized as a spray-applied foam or rigid plastic for energy conservation.
Photovoltaic (PV) Roof Panels come with risks such as electric shock, roof collapse, and releasing toxic materials in fires.

Firefighter Safety and Protocols

Firefighters should avoid cutting through PV panels during emergencies to prevent electrocution and equipment damage.
Building-Integrated Photovoltaics (BIPV) integrate PV systems into building materials, enhancing aesthetics and energy production.
It’s vital for fire departments to include notes like “GC electrical roof hazards” in preplans for buildings with green energy systems.

Specialized Systems and Equipment

Off-Grid PV Systems operate independently from the public electrical grid and necessitate battery storage.
Risks are associated with batteries in Off-Grid Systems due to shock hazards and potential hydrogen gas explosion.
Roof-Mounted Wind Turbines convert wind energy into electricity but pose dangers from their spinning blades during firefighting efforts.

Sustainable Water Management

Rainwater Reclamation Systems enable the storage and use of rainwater for building needs.
Gray Water Systems are designed for fire suppression and irrigation, enhancing water efficiency.

Insulation and Fire Safety

Certain materials like polystyrene and polyurethane may increase fire risks while being used for insulation.
Glass insulation can accelerate fire development due to delayed breakage under heat.
Precautions like using horizontal ventilation or PPV fans are crucial when dealing with green roofs during a fire.

Vegetation Management

Vegetation on building walls can become highly combustible if not properly maintained, posing fire hazards.
Firefighters should prioritize horizontal ventilation, avoiding vertical approaches that could hinder access and ventilation.

Planning and Safety Measures

Preplanning is vital for identifying hazards related to buildings with green energy systems to enhance firefighting strategies.
Water storage tanks, while useful, can add significant dead loads, elevating the risk of collapse in green buildings.

Emerging Materials and Technologies

Biopolymers are renewable and combustible materials used in construction, presenting new challenges in fire safety.
The U.S. Green Building Council administers the LEED certification program, promoting sustainable building practices.
