Guide – What the Value Means

Emission class, pile weight, A1–A3, CoClass.What do all these classifications and values mean in relation to your project and products?

Updated yesterday

Conservative Values

When a climate declaration is being prepared, data from the Swedish National Board of Housing, Building and Planning’s (Boverket) climate database or specific climate data for construction products can be used. The climate data in Boverket’s database is conservatively estimated—about 25% higher than average—to encourage the use of specific climate data. Climate data for energy and fuel must be retrieved from Boverket’s database and are not conservatively estimated.

CO2e A1–A3 (Biogenic)

Biogenic carbon dioxide is carbon bound in biomass, which includes plant-based materials from nature—forests, agriculture, or water—as well as agricultural and food industry by-products, including slaughterhouse waste. When the biomass is burned or decomposes, the same amount of biogenic CO₂ is returned to the atmosphere.

This is measured in carbon dioxide equivalents (CO2e) using life cycle analysis (A1–A3) in accordance with ISO 14040 and ISO 14044.

CoClass

CoClass is a unified classification system for the built environment, designed to ensure future-proof documentation.

Boverket

Boverket is the administrative authority for issues relating to the built environment, land and water use, physical planning, construction, housing, and housing finance. Boverket operates under the Ministry of Finance.

CMR

Carcinogenic, mutagenic, or reprotoxic chemical substances are referred to as CMR substances. These are particularly hazardous and dangerous through inhalation, ingestion, or skin contact. It's essential to consider the full handling chain, including equipment cleaning and waste management.

BASTA

BASTA is a database of construction products that meet BASTA’s chemical content requirements.

  • BASTA criteria: Concern phase-out substances and risk-reduction substances. Products meet Miljöbyggnad GOLD (versions 2.2 and 3.0) and BREEAM SE.

  • BETA criteria: Allow risk-reduction substances and meet Miljöbyggnad GOLD (2.2) and SILVER (3.0).

Content Certifications

  • HPD Open Standard: Promotes accurate and consistent reporting of product content and health information for building products. Compatible with several industry standards.

  • Declare: An internationally recognized transparency platform listing product origin, ingredients, and end-of-life pathways.

Humidity RH

Relative humidity (RH) in materials is a measure of how "moist" a material is, according to EN 318.

Emission Class

Indoor air quality classification for materials used in buildings.

  • M1: Tested in neutral labs per M1 standards.

  • A1 & A1+: Based on French regulations.

  • Indoor Air Comfort (IAC): Confirms product emissions meet EU regulations.

  • IAC GOLD: Meets additional voluntary eco-label standards in the EU.

Ceiling Sound Insulation

Reduction of noise through ceilings, measured as above.

Sound Absorption Class

Rating from A to E (A = best), defined in ISO 11654.

U-Value

A window's energy efficiency rating. The lower the U-value, the better the insulation. Calculated per SS-EN ISO 6946.

CO2e A1–A3 (Fossil)

Carbon emissions from fossil fuels. Measured in CO2e per ISO 14040 and ISO 14044.

Emissions or removals of greenhouse gases due to land use activities. Calculated in CO2e per ISO 14040 and ISO 14044.

Data Quality

Prodikt classifies data quality as:

  • A: Product-specific EPD = very high quality

  • B: Family-specific EPD = minor deviation possible

Climate Impact

The product’s total CO₂ emissions from raw material extraction to finished product. Calculated in CO2e via ISO 14040 and ISO 14044.
Example: 500 km in an average car ≈ 100 kg CO2e.

SIN List
