The manufacturing energy influences the overall energy balance of a building. The Manufacturing Energy Evaluation Tool (MEET) was developed to evaluate the potential energy expenditures and greenhouse gas emissions (in CO2 equivalents) that arise during the production of building materials and components, and to compare these with the operational energy of a building. This allows for a comprehensive analysis of both energy forms – manufacturing and operational – within a single tool.
MEET thereby is an essential tool for a holistic lifecycle assessment of a building’s energy efficiency. It supports planners and architects in making well-informed decisions that consider both manufacturing and operational energy. It also demonstrates that a marginally higher manufacturing energy for products with superior thermal insulation qualities can be advantageous, as these products frequently result in substantial energy savings during operation. In practice, it is often shown that operational energy has a more decisive impact on the overall energy balance of a building.
For more information on the calculation methods, please refer to this Passipedia page and the attached report (or click on the image to the right).
MEET: Manufacturing Energy Evaluation Tool
The tool is, along with the report, is available for download above. It is a standalone tool that provides a comprehensive evaluation of the manufacturing energy and the greenhouse gas potential of building materials. Simultaneously, it also approximates the operational energy of the building. It assists in the assessment and comparison of:
- Individual materials
- Window components and opaque assemblies
- Entire buildings under specific climatic conditions
MEET 2: Next Generation of the Tool (beta)
With the introduction of the second version, the tool now offers enhanced functionality and a direct connection to the Passive House Planning Package (PHPP). Specifically, this means:
- User-Friendly Material Selection: The material input has been improved through an extensive building material list and a filtering mechanism. Additionally, the input for windows and doors has been made more intuitive.
- Integration with PHPP: MEET 2 is linked to PHPP 10, enabling a detailed determination of operational energy. All relevant energy data, as well as data on the composition of the building envelope, are transferred easily using an embedded interface sheet.
As MEET 2 is currently in its beta stage, we invite you to try the tool with your PHPP 10.6 (or higher). Please contact us at tools[at]passiv.de to receive the latest version of the interface sheet. We look forward to your feedback!
