Description:

The tool is performance-oriented, focuses on highly energy efficient details and building, much more flexible than a thermal bridge catalogue, and much faster than a thermal bridge program. Therefore, the use is time-saving for designers and consultants. Many configurations are implemented in the tool allowing users a wide range of input possibilities. The user can play with different inputs, receiving straightforward feedback, which allows fast optimisation.

Thermal bridge catalogue with many details and variants especially for high performance new buildings. In addition, it is also important and useful for renovations.

Details:

> External wall – outer corner (EWEC01)

> External wall – inner corner (EWIC01)

> Roof ridge (roof inclination 30°,45°,60°) (RORI01)

> Roof eaves (roof inclination 30°,45°,60°) (ROEA01)

> Roof verge (ROVE01)

> Balcony (BALC01)

> Porch roof (BALC02)

> Roof parapet (FRRP01)

> External wall - ceiling (EWCE01)

> Window connection (side) (WISI)

> Floor slab – external wall (FSEW01)

> Basement ceiling – external wall (BCEW01)

> Basement ceiling – internal wall (BCIW01)

User:

Designers who are not familiar with Ψ-value and fRsi -values can easily use the tool to check thermal bridge coefficients and surface temperature factors of similar connection details. Then using those factors as a basis for evaluating a project, designers can easily determine the connection quality, improve it and optimise the design´s cost efficiency.

Input:

Connection name; construction system type (brick wall/concrete wall); optimisation (yes/not); thermal conductivity of the insulation material; insulation thickness.

Output:

Wall U-value; Ψ-value; fRsi -factor.

Challenge:

A background knowledge about thermal bridges and a certain knowledge is necessary. The designer needs to be able to judge if the result presented by the “Thermal Bridges Tool” can be transferred or used in case of his individual project.

Outcome:

The “Thermal Bridges Tool” simplifies the design and optimisation process of energy-efficient buildings. Time and effort by the designers is saved in the thermal bridges calculation process. The tool also very easily facilitates the evaluation and optimisation of the most common connections in terms of hygienic quality and cost efficiency.

Accordingly, the effectiveness of the building design is supported, construction costs are saved, and affordable nZEBs’ cost effectiveness is improve

Format:

Microsoft Excel and operates under Microsoft Windows
