Sustainability
Economic and ecological

Our aim is to organise our planning and implementation processes efficiently and to optimise the use of materials and energy in line with the project requirements - for people and the environment. We prioritise durable materials and high-quality workmanship, and adhere to recognised building standards. The concept is designed in such a way that the requirements for ÖGNI Gold certification can be met on a project-by-project basis.

ÖGNI Gold

The certificate covers the following aspects of future-oriented planning and construction, developed based on the ÖGNI criteria (Austrian Society for Sustainable Real Estate Management).

Ecological Quality

Checked materials and the targeted use of timber are taken into account when evaluating environmental impacts as part of the life cycle assessment.

Economic Quality

By taking a life-cycle approach, ensuring value retention and carrying out a climate risk analysis, we create a building that is economically viable in the long term, with a focus on maintaining value and flexibility of use.

Sociocultural & Functional Quality

High living comfort through an optimized indoor climate, plenty of natural light, healthy indoor air and barrier-free design.

Technical Quality

An efficient building envelope, integrated building services and a durable construction to ensure low energy consumption and a long service life.

Process Quality

Sustainability considerations are taken into account right from the early stages of planning and implementation.

Location Quality

Good links to public traffic, together with provision for cycling and walking infrastructure, ensure long-term quality and use.

EU Taxonomy

PORR Systembau is designed and constructed as an ‘EU Taxonomy-eligible’ concept and, at the client’s request, certified as an ‘EU Taxonomy-compliant’ building. The concept has been developed in such a way that the location-independent requirements of the EU Taxonomy can be met. Actual taxonomy compliance must be demonstrated on a project-by-project basis.

By using timber as a COâ‚‚-storing building material, a building envelope with high density and optimised, passive-oriented mechanical & electrical engineering, the system can reduce energy consumption and emissions. The system-based construction approach can therefore contribute to achieving the relevant EU taxonomy targets.

Through the evaluation of site quality using climate risk analysis, the aim is to enhance the building’s resilience to identified climate risks. In this way, the system supports the integration of climate resilience considerations into the planning process.

Through water and energy-saving schemes, the system incorporates measures designed to ensure the efficient use of water resources and to protect soil and groundwater.

By assessing the construction and choice of materials in terms of their suitability for dismantling and recycling, these factors are taken into account as part of the project evaluation.

A process involving the testing of materials and products prior to installation, with regard to limit values for harmful substances (VOCs, SVHCs and formaldehyde), is designed to ensure a high standard of indoor air quality. In addition, on-site processes such as low-noise and low-dust working methods, waste-minimising procedures and the protection of the floor and groundwater help to reduce environmental pollution.

Modular construction can support biodiversity by consistently avoiding invasive plant species in outdoor areas and by placing artificial lighting that is species-friendly, for example to protect nocturnal animals. Furthermore, drawing up a biodiversity strategy can help to preserve and promote diverse habitats on site.
