LEED Life Cycle Assessments mit LCA-Online

Erstellen Sie mit LCA Online einfach Ihre LEED Life Cycle Assessments und Ökobilanzen. Sie haben dabei verschiedene Auswertungsmöglichkeiten, wodurch Sie bis zu 4 Punkte für Ihr LEED Projekt erreichen können. 

Ihre Vorteile mit LCA Online:

• anerkannte LCA Software für LEED
• Nachweis von bis zu 4 Punkte für Ihr LEED Projekt
• voreingestellte Auswertungsmöglichkeit gemäß LEED
• vorkonfigurierte Produkte und Bauteile für LEED

Gerne erstellen wir auch für Ihr Projekt die Ökobilanz gemäß LEED entsprechend Ihrer angestrebten Punktzahl.

Sie können mit LCA online folgende Kriterien nachweisen:

LEED v4 Building Design and Construction (BD+C) 

Option 4. whole-building life-cycle assessment (3 points)

For new construction (buildings or portions of buildings), conduct a life-cycle assessment of the project’s structure and enclosure that demonstrates a minimum of 10% reduction, compared with a baseline building, in at least three of the six impact categories listed below, one of which must be global warming potential. No impact category assessed as part of the life-cycle assessment may increase by more than 5% compared with the baseline building.

The baseline and proposed buildings must be of comparable size, function, orientation, and operating energy performance as defined in EA Prerequisite Minimum Energy Performance. The service life of the baseline and proposed buildings must be the same and at least 60 years to fully account for maintenance and replacement. Use the same life-cycle assessment software tools and data sets to evaluate both the baseline building and the proposed building, and report all listed impact categories. Data sets must be compliant with ISO 14044.

LEED v4.1 Building Design and Construction (BD+C) 

Option 2. Whole-Building Life-Cycle Assessment (1-4 points)

For new construction (buildings or portions of buildings), conduct a cradle-to-grave life-cycle assessment of the project’s structure and enclosure and select one or more of the following paths below to earn up to 4 points:

• Path 1: Conduct a life cycle assessment of the project’s structure and enclosure (1 point).
• Path 2: Conduct a life cycle assessment of the project’s structure and enclosure that demonstrates a minimum of 5% reduction, compared with a baseline building in at least three of the six impact categories listed below, one of which must be global warming potential (2 points).
• Path 3: Conduct a life cycle assessment of the project’s structure and enclosure that demonstrates a minimum of 10% reduction, compared with a baseline building, in at least three of the six impact categories listed below, one of which must be global warming potential (3 points).
• Path 4: Meet requirements of Path 3 and incorporate reuse and/or salvage materials into the project’s structure and enclosure for the proposed design. Demonstrate reductions compared with a baseline building of at least 20% reduction for global warming potential and demonstrate at least 10% reduction in two additional impact categories listed below (4 points).

For Paths 2, 3 and 4 listed above, no impact category assessed as part of the life-cycle assessment may increase by more than 5% compared with the baseline building. Include a narrative of how the life cycle assessment was conducted and if applicable for paths 2, 3 and 4 what changes were made to proposed buildings in order to achieve the related impact reductions.

The baseline and proposed buildings must be of comparable size, function, orientation, and operating energy performance as defined in EA Prerequisite Minimum Energy Performance. The service life of the baseline and proposed buildings must be the same and at least 60 years to fully account for maintenance and replacement. Baseline assumptions must be based on standard design and material selection for the project location and building type. Use the same life-cycle assessment software tools and data sets to evaluate both the baseline building and the proposed building, and report all listed impact categories. Data sets must be compliant with ISO 14044.
