Economic and ecological life cycle analysis of environmentally relevant technical building equipment for residential buildings with high solar coverage

In the construction industry, effective changes with regard to the conservation of resources are urgently needed. The basis for this transformation is the implementation of the European Commission's long-term strategy “low-carbon economy by 2050”. At the same time, the Austrian Institute for Building Technology (OIB) defines the framework conditions for cost optimality with reference to the overall energy efficiency of buildings.

The Austrian organization Network Solar House Austria has ascertained that its members have definitely acquired a robust knowledge of the technical planning principles for zero energy buildings, but that the mastery of life cycle relationships in more complex energy concepts, due to the individual framework conditions for each property, is still often insufficient. The optimization of the technical equipment of residential buildings with high solar cover is a complex task with regard to the cost optimality and the lowest possible environmental impact in a life cycle view. The solution to this task necessarily requires the cooperation of diverse disciplines.

This qualification seminar is characterized precisely by this interdisciplinary composition of both the seminar participants from 10 different SMEs as well as the scientific teaching team.

Qualification Goals and Desired Results

The qualification seminar enables the seminar participants to create and appraise both an economic and an ecological assessment of planned building services system concepts for buildings with high solar coverage in the life cycle.

The focal points are:

• Low tech
• Reduction of CO₂ emissions
• Investment and operating cost optimization

After five days of training, the seminar participants will be qualified to provide an overview of the key factors influencing economic and ecological amortization times as well as the operating costs of solar energy-based building services systems, to create cost-optimized plans and to explain the environmentally relevant benefits to the involved planning and construction professionals in an understandable way. In this way, the project results are not only disseminated within the company, but also outside of the participating consortium.
