The aim of Priedemann’s thermal-structural planning is to minimise heat losses and undesirable heat input through the exterior of the building and to avoid damage caused by weather conditions. The range of services includes identifying all influences and values relevant for the facade structure as well as the exact dimensioning and determination of the materials for the layer structure of the facade.
- Thermal insulation: On the basis of local and specific project requirements and after evaluation of the technical building plan, we determine the necessary values for thermal insulation in the summer and winter.
- Energy standards: We take into account which energy standards and objectives must be met – such as KfW requirements, low and passive house standards or requirements of green building labels such as LEED, BREAM or DGNB.
- Materiality: We calculate the necessary U-values and resulting insulation thicknesses, make specific material suggestions, give advice on the correct wall structure and determine the g-values taking into account the measures selected to provide protection from the sun.
- Overall energy performance: We determine the necessary values from building services and the facade to work out the overall energy performance of the building. An important component, especially in residential buildings, is the calculation of the transmission heat loss of the entire exterior of the building.
- Isothermal profile and thermal bridges: We analyse the isothermal profile within the planned or implemented construction, calculate 2 or 3 dimensional thermal bridges and give recommendations to avoid condensation forming
- Component construction with layer construction: Depending on the commission, we draw up a catalogue for the entire building or selected components, which shows the scale of each individual component in its layer structure and specifies the material qualities in order to give those involved in planning certainty about the structural-physical qualities of the planned construction.
- Advice throughout every phase: This is the basis on which we advise architects and builders, general contractors and facade manufacturers, whom we assist in all planning and implementation phases.
- Calculating and adjusting noise level values: We determine the noise-level values that occur locally as the basis for planning the necessary noise protection and the required noise protection values for individual rooms, taking into account the planned use. We compare the values obtained with the legal and project-specific requirements.
- Determination of the requirements for the facade components: From this we can deduce the requirements for the facade components and recommend suitable constructions and material qualities. We take into account the flank transmission over adjacent components and spaces and influence the arrangement and design of the substructure, the choice of window and glazing types as well as the selection of materials and sensible arrangement of joins
- Ambient noise level: We determine the ambient noise level and reverberation times in the room and give recommendations on sound absorption and the distribution of sound-absorbing elements and surfaces.
- Preparation of sound- and noise protection reports: We prepare sound and noise protection reports as part of the approval process.
- Evaluation of internal emissions: We evaluate the emissions of technical installations and give recommendations for compliance with the prescribed noise level values.
- Sound pressure: We define the structural conditions for the maximum permissible sound pressure level in rooms where protection is required.
- Sound absorption: We calculate the sound-absorption surfaces required and propose suitable sound-absorbing materials and surfaces as well as their positioning within the framework of a spatial concept.
Improving the intelligibility of speech: We develop ways to make speech intelligible and to avoid disturbing echoes in the room. - Improving the intelligibility of speech: We develop ways to make speech intelligible and to avoid disturbing echoes in the room.
Priedemann produces energy saving certificates based on the existing building data, which represent the most important energy consumption data and characteristic values in accordance with local legal requirements. For Germany we are also authorized to assess such evidence.
For completed projects or ongoing projects – depending on local regulations and the determination of specific building data – we can issue energy efficiency certificates that illustrate the energy consumption of the building as a whole, i.e. in the interaction of building services, facade and use.
