Integrated solutions for new buildings, conversions, renovations and housing subsidies – with personal guidance at the centre of every project.

Thermal protection

Well-designed thermal protection reduces energy losses, improves thermal comfort and protects buildings against summer overheating.

• Calculation of U-values and thermal performance indicators for building components
• Sizing and optimisation of thermal insulation for new builds and renovations
• Evidence of summer thermal protection and prevention of summer overheating
• Development and assessment of shading strategies
• Calculation of surface temperatures at critical construction junctions

Moisture protection

Proper moisture protection safeguards building components against condensation, mould growth and long-term moisture damage.

• Calculation of water-vapour diffusion and condensation behaviour in building components
• Assessments to prevent surface condensation and mould growth
• Investigation and evaluation of existing moisture and mould damage
• Development of suitable measures to prevent damage and support remediation

Energy certificates

Energy performance certificates document the energy quality of buildings and provide an essential basis for planning, building approvals, subsidies and renovation.

• Preparation of energy performance certificates for residential and non-residential buildings
• Energy certificates for new builds, conversions, existing buildings and renovations
• Calculation of energy performance indicators in line with applicable legal requirements
• Energy assessment and optimisation of the building envelope
• Calculation and comparison of different insulation and renovation options

Housing subsidies

Early coordination of building-physics requirements creates a reliable basis for housing subsidies and authority procedures.

• Advice on building-physics requirements for housing subsidies in Austria
• Assessment of energy-related subsidy eligibility for new builds and renovations
• Energy calculations comparing options to meet subsidy requirements
• Coordination with subsidy authorities, public agencies and project participants

Sound insulation

Effective sound insulation reduces disturbing noise within buildings and protects against noise from the surroundings.

• Calculation of airborne and impact sound insulation
• Assessment of sound transmission via flanking components and indirect paths
• Assessment of service-installation noise and sound transmission through building services
• Acoustic assessment and development of noise-control measures for heat pumps and other building-services equipment
• Outdoor sound-propagation calculations and preparation of acoustic reports assessing noise impacts on neighbouring properties

Room acoustics

Well-designed room acoustics improve speech intelligibility, reduce disturbing reverberation and create pleasant listening conditions.

• Room-acoustic concepts for training, teaching, seminar and meeting rooms
• Reverberation-time calculations and assessment of room-acoustic quality
• Planning and optimisation of acoustically effective ceiling and wall surfaces
• Noise-reduction concepts for offices, workplaces and hospitality venues

Sustainability

Sustainable construction combines resource-efficient materials, environmental assessments and practical long-term building concepts.

• Life-cycle assessments (LCA) for building components and entire buildings
• Calculation and assessment of the OI3 ecological index
• Assessment of environmental impacts of building materials and constructions
• Calculation and assessment of building-related greenhouse gas emissions
• Environmental optimisation of building assemblies and constructions

Building certification

Building certifications make sustainability performance measurable and support holistic, future-oriented building planning.

• Consulting on building certification under the ÖGNI/DGNB system
• Analysis of certification criteria and identification of optimisation potential
• Assistance with compiling and documenting certification records
• Coordination of sustainability requirements with project participants and ÖGNI auditors

Renovation concepts

A holistic renovation concept combines the existing building condition with technically sound, economically transparent and durable measures.

• Building-physics survey and assessment of existing constructions
• Development of thermal renovation measures
• Calculation and comparison of different renovation alternatives
• Development of coordinated measure packages and sensible renovation stages
