LEED Basics: What You Need to Know

What is LEED?

LEED, or Leadership in Energy and Environmental Design, is the world’s most widely used green building certification system. It sets clear standards for energy efficiency, water use, material selection, indoor air quality, and overall LEED environmental performance. Buildings that follow LEED guidelines are designed to be healthier, more efficient, and more sustainable across their entire lifecycle.

Why LEED Matters for Architects, Builders, and Developers

For industry professionals, LEED is more than a certification it is a framework that guides smarter decisions. Architects use LEED to validate sustainable designs. Builders rely on it to meet global construction standards. Developers achieve stronger market value, reduced operating costs, and higher tenant demand with certified projects. LEED also helps teams communicate that their building is designed with long term environmental and economic responsibility in mind.

Rising Demand for Green Building Certification and Sustainable Materials

Across the world, clients and governments are asking for greener, healthier buildings. LEED certification has become a trusted benchmark that proves a project meets modern sustainability expectations. This demand is pushing architects and builders to choose low carbon, durable, and responsibly manufactured materials including advanced porcelain tiles even though Ramirro Ceramica do not provide LEED certified tiles, we do offer sustainable material options that can support certain environmental goals within a project.

Understanding LEED Certification

What is LEED Certification?

LEED certification is a global standard that measures how sustainable, efficient, and environmentally responsible a building is. Developed under the LEED program, it guides project teams in creating LEED buildings that use fewer resources, reduce environmental impact, and offer healthier indoor spaces. LEED certification applies to both new construction and existing structures, helping professionals integrate smarter LEED design strategies into every stage of development.

USGBC & GBCI: Who Oversees LEED?

The LEED framework is managed by two key organizations:

USGBC (U.S. Green Building Council) – the body that created the USGBC LEED standards and provides guidelines for green building practices.

GBCI (Green Building Certification Institute) – the organization responsible for reviewing project submissions, verifying sustainability claims, and officially awarding certifications.

Types of LEED Certifications

Based on the total points earned, a project can achieve one of four types of LEED certification. These levels reflect how well a building meets LEED environmental criteria:

LEED Certified (40-49 points)

LEED Silver (50-59 points)

LEED Gold (60-79 points) a highly respected achievement that demonstrates strong sustainability performance; often referred to as LEED Gold certification

LEED Platinum (80+ points) the highest level, showcasing exceptional efficiency and environmental responsibility; commonly known as LEED Platinum certification

LEED Rating Systems Overview

The LEED rating system is divided into categories based on project type and scope. Each category focuses on specific sustainability goals and design requirements.

BD+C (Building Design and Construction) For new buildings and major renovations; covers LEED building design and construction strategies.

ID+C (Interior Design and Construction) For interior spaces such as offices, retail stores, and hospitality interiors.

O+M (Operations and Maintenance) For existing buildings seeking improved performance and long term efficiency.

How Material Selection Impacts LEED Scores

LEED Credits Related to Materials

Low Emitting Materials: Materials that release fewer chemicals and VOCs improve indoor air quality and help projects earn LEED credit under this category.

Construction Waste Reduction: Using materials that generate less waste, or support recycling and reuse, contributes to LEED sustainability goals.

Environmental Product Declarations (EPDs): EPDs provide verified environmental data about a product’s life cycle. Using products with EPDs can earn additional LEED credit.

Recycled Content: Materials made from post consumer or pre consumer recycled content help reduce resource extraction and support LEED environmental performance.

Regional Materials: Products sourced within a defined distance help reduce transportation emissions and support the local economy.

Life Cycle Impact Reduction: This credit rewards materials with lower environmental impact across their full life cycle from production to disposal.

Material Transparency Requirements

Common transparency documents include:

EPDs (Environmental Product Declarations): Provide life cycle environmental impact data.

HPDs (Health Product Declarations): Disclose material ingredients and potential health effects.

GREENGUARD Certification: Verifies that a product meets strict chemical emission standards for better indoor air quality.

Porcelain vs Natural Stone: Which Scores Higher in LEED?

Carbon Footprint Comparison

Natural Stone – Higher Embodied Carbon

Extracting natural stone requires quarrying, heavy transportation, and energy intensive finishing. These processes create a high embodied carbon footprint, which can negatively influence overall sustainability metrics.

Porcelain – Significantly Lower Carbon Impact

Porcelain generally has a lower carbon footprint because its raw materials are lighter and manufacturing processes are controlled within a single facility. This makes porcelain more supportive in green building LEED scoring when evaluating environmental impact.

Manufacturing Sustainability (SPF & Eco Practices)

Efficient Kilns: New kiln technology reduces energy use and carbon emissions.

Zero Waste Firing Systems: Unfired material is recycled back into production.

Water Recycling: Closed loop systems minimize water consumption.

Low VOC Emissions: Porcelain releases extremely low emissions, supporting better indoor air quality.

Natural stone, while a natural material, does not inherently follow these controlled sustainability practices, as it depends heavily on quarry processes, transport, and surface treatments.

Maintenance & Life Cycle Impact

Natural Stone – Higher Maintenance

Stone typically requires sealing, chemical cleaners, and constant upkeep. These added materials and chemicals increase environmental impact over the building’s life cycle.

Porcelain – Lower Maintenance & Longer Lifespan

Porcelain is durable, stain resistant, and often needs no chemical treatment. This long life and minimal upkeep support LEED strategies focused on long term durability and reduced maintenance impact, potentially contributing indirectly to higher sustainability scores.

Waste & Water Management

Natural Stone – High Slurry Waste

Cutting natural stone generates large amounts of slurry, which is difficult to recycle and often disposed of as waste.

Porcelain – Closed Loop Systems

Porcelain factories typically use recycling systems where water, dust, and rejected materials are reused. This significantly reduces landfill waste and supports efficient resource management.

How Using Porcelain Tiles Helps You Earn More LEED Credits

Materials & Resources (MR) Credits

Material durability: Long lasting materials reduce replacement frequency and lower environmental impact over the building’s life cycle.

Recycled content (if available in certain brands): Some porcelain products may include recycled raw materials, which can help in applicable MR credits.

Responsible manufacturing practices: Factories using closed loop systems, water recycling, or waste reduction practices help support LEED goals such as life cycle impact reduction.

Although porcelain tiles themselves may not carry LEED certification, their performance characteristics align with MR requirements that encourage long lasting, low impact materials.

Indoor Environmental Quality (IEQ) Credits

Low VOC emissions: Tiles do not emit harmful chemicals, helping reduce indoor pollution and supporting IEQ credit compliance.

Allergen resistance: Porcelain surfaces do not trap dust, mold, or bacteria, improving occupant comfort.

Easy cleaning without chemicals: Less reliance on harsh cleaners contributes to better indoor air quality over time.

Sustainable Sites (SS) Benefits

High solar reflectance (in light colored tiles): Helps reduce heat island effect in outdoor spaces.

Durability in harsh conditions: Long lasting surfaces lower maintenance frequency and reduce resource use.

Water Efficiency (WE) Considerations

While tiles do not directly earn Water Efficiency credits, porcelain indirectly supports this category through:

Reduced cleaning water: Porcelain’s stain resistance means it requires minimal water for cleaning.

Fewer chemical cleaners needed: Less chemical use aligns with broader sustainability goals.
