GRUPPO CONCORDE

• LEED is not: LEED is not a product certification.

• LEED is: LEED is a building rating.

– Verified by indipendent credited Institutes.

– With multiple levels of building certifications: certified, silver, gold, platinum.

GRUPPO CONCORDE

The LEED 6 thematic areas• 1. Sustainable Sites.

• 2. Water Efficiency.

• 3. Energy and Atmosphere.

• 4. Materials and Resources.

• 5. Indoor Environmental Quality.

• 6. Innovation in Design.

Credits MR 4• Recycled material content 10% (post-

consumer + ½ pre-consumer): 1 point

• Recycled material content 20% (post-consumer + ½ pre-consumer): 2 points

• Post-consumer : Waste material from final user• Pre-consumer: Industrial waste material (from a

source different than the applicant)

GRUPPO CONCORDECrediti MR 5

(regional material)• Requirements: use of

material or building products extracted, found, recycled and manufactured within 500 miles from the project location, contribute to:

• a minimum of 10% of the value (based on cost) of the total material used: 1 point

• a minimum of 20%: 2 punti

GRUPPO CONCORDECredit ID 1

innovation in design• “Extraordinary performances with reference to the

LEED ratings”Or

• " innovative performances for green building with no explicit relation to the Green Building Rating System”

1 point for every innovation achieved (5 points maximum)

Examples:• “Ecolabel” products• Our productions respect and improve the BAT ( Best available techniques)• The new “thinner” porcelain tiles

GRUPPO CONCORDECREDIT SS 7.1/7.2

• 7.1 Heat Island effect (excluding roof and coverings)• 7.2 Heat Island effect (roof and coverings)

Purpose: Reducing the Heat Island effect (thermal difference between urban and non urban areas) in order to minimize microclimate impact.REQUIREMENTS:a. Implement a combination of all the following strategies on 50% of the

built area (including streets, tracks, courtyards and parking lots) - Solar shading (within 5 year from occupancy)- Flooring materials with a Solar reflection index

(SRI) of 29 or greater.- Open grids flooring systems

b. Include a 50% minimum of covered parking spaces (underground, under roof, under cover or under a building). Every roof used to solar shading of parking spaces needs to have a SRI ratio equal or greater than 29

GRUPPO CONCORDEPre-requirements EA-2 and EA1 Credit

• Pre-requirement EA-2: defines the minimum level of the building energetic efficiency

• EA1 credit: achieve energetic performaces greater than the pre-requirement.

TILES:• THERMAL CONDUCTIVITYTHERMAL CONDUCTIVITY: the quantity of heat perpendicularly

transferred to a surface due to temperature gradient • Measurement: 1.08 (W/m²K)• Materials with low thermal conductivity

Building energetic efficiency

GRUPPO CONCORDECREDIT EQ 4.2

PURPOSE: reduce the quantity of air pollutants

REQUIREMENT: The floors need to comply with the requirements of California Department of Health Services “VOC” regulation (Volatile Organic Compounds)

TILES:• VOC quantity <1mg/Kg<1mg/Kg (express in total carbon) below the instrument

detection limit (UNI EN 13649:2002)• Carbon volatility (T°<900C ) during the gres pre-cooking phase

(T°C>1200°C)
