Building Physics

An appropriate indoor climate and suitable soundproofing in building construction projects

Two central requirements for new buildings are enhanced energy values and low heat loss. Responsible use of resources and a general desire for efficient and sustainable construction have increased the focus on aspects of building physics.

The EU-wide EPBD (Energy Performance of Buildings Directive) was adopted to reduce buildings’ energy consumption. This means that heat insulation measures for new buildings will be adapted successively until 2020. PORR Design & Engineering offers consultancy in this field and supports the planning process for building construction projects from a building physics perspective. On the one hand, we make recommendations with regard to building regulations and user guidelines; on the other hand, we also provide support in building optimisation in the areas of heat insulation, sound insulation and architectural acoustics above and beyond basic fulfilment of legal requirements, norms and guidelines.

Our building physics consultancy does not stop with the planning process: when issues arise, we support our clients and work with them to develop solutions. 

Building physics and sustainability – from planning permission through to implementation

At PORR Design & Engineering, we can look back on over 15 years of planning expertise in the field of building physics. Sustainability plays a substantial role in our construction planning: from obtaining planning permission to providing construction site support, we handle resources efficiently and provide our clients with energy consultancy.

The following detailed services fall within the scope of building physics:

  • Planning in line with the latest energy-saving directives (OIB [Austrian Institute of Construction Engineering], EnEV [German Energy-Saving Ordinance]) for residential buildings, offices, factories and hotels
  • Soundproofing, heat insulation and architectural acoustics
  • Measures to prevent condensation problems and mould
  • Thermographic measurements (thermal imaging camera)
  • Building air density measurements (blower door test)
  • Air and impact sound measurements
  • Sound measurements for building engineering facilities
  • Thermal bridge calculations 
  • Energy certification for buildings
  • Consultancy and support at the construction site
