The Solar House – A nearly Zero Energy Building at Transilvania University of Brasov, Romania

About this good practice
The Solar House developed by the public entity of Transylvania University of Brasov in Romania is focused on contributing to the reduction of energy demand, as well as to the increase of the energy efficiency, and renewable energy production and it constitutes an intervention which is consistent with the policy conducted by the university, but also with the objectives set forth by Brasov County Council`s Strategy such as diminishing CO2 emissions and developing nZEB. The Solar House addressed problems related to the high share of fossil fuels used in a built environment, the depletion of these resources and increase of environmental pollution generating important climate changes. The Solar House goes beyond mere energy efficiency; it serves as a dynamic teaching and research facility, providing invaluable hands-on learning experiences for students specializing in renewable energy engineering. The building's design combines passive solar strategies, such as maximizing natural light and solar gain through strategic window placement, with an advanced renewable energy system. This system encompasses a geothermal heat pump for heating and cooling, solar thermal collectors for domestic hot water, a photovoltaic system for electricity generation, significantly reducing reliance on fossil fuels and minimizing the building's carbon footprint. The resulting drastic reduction in energy consumption demonstrates the tangible benefits of a holistic approach to sustainable building design.
Resources needed
The investment was 250,000 €, covering the costs of construction and implementation of comprehensive RE systems,100% by university funds. The ongoing maintenance expenses are low, consisting of routine upkeep managed by students as part of their academic studies and practical training.
Evidence of success
The success of the practice consists in achievieng nZEB standards.In 2020 the building's thermal energy demands were completely met by the RE systems and 70% of the electricity needs were supplied by PV systems,resulting in reductions in CO2 emissions.The project has yielded numerous publications in scientific journals,showcasing the innovative aspects of its design and operation,becoming a teaching and research tool,providing practical learning opportunities for students.
Potential for learning or transfer
The Solar House offers valuable lessons and a replicable model for other institutions and builders striving to achieve sustainable building practices. The innovative design, combining passive solar strategies with advanced RE technologies, can be adapted to different climates and building types, although site-specific considerations will be necessary for optimal performance. The project highlights the educational benefits of integrating RE systems into teaching and research, enriching students' learning experiences and contributing to the advancement of knowledge in the field. The comprehensive monitoring and data-collection procedures used in the Solar House provide information for future research and development in sustainable building design. The project's longevity, operating for over 15 years, strongly demonstrates the durability and cost-effectiveness of long-term investment in RE technologies, making it a compelling case study for sustainable development initiatives worldwide.
