Library ventilationWe can minimise energy consumption in libraries through proper energy planning.
Library ventilation and air-conditioning
Library ventilation and air-conditioning requires properly ventilated areas. Proper air-conditioning and ventilation are an important aspect of both reading rooms, where many visitors read, study or use computers, and library halls, where paper slowly acquires its aroma; a regular exchange of air is therefore needed. Larger libraries have specific needs for clean rooms or areas, where the required temperature and humidity levels must be carefully maintained, so the very old archived books are properly cared for and, consequently, have their lifetimes prolonged.
We have received an award from the European Commission for our Split University Library project (Croatia): EU GreenBuildingAward for the best energy project of the year 2009.
Project summary: Split University Library
The Split University Library is a flexible open-spaced building complex, combining traditional barriers of the library, library users and librarians. It is an urban and humanised space, providing a creative atmosphere for learning, writing and creating.
The library comprises a bookshop, paper mill, commercial gallery, exhibition hall, café and restaurant, multifunctional hall, student assembly room… It also contains special storage areas with specific climate and microclimate requirements for storing and conserving special publications and written cultural heritage.
Highly-efficient energy solution
The building represents a completely intergrated high-class solution with the highest level of optimisation of building physics.
During the early phase of the project, we managed to outline a uniform energy concept, which also included close cooperation of an architect and a designer. The extent of the energy concept:
- ventilation and air-conditioning,
- preparation of cooling energy,
- preparation of heat energy,
- use of alternative energy sources,
- digital regulation or building automatisation,
- central control system.
The solution was designed using a high rate of energy recovery from waste air, and optimised for the use of indirect adiabatic cooling. An alternative option of free cooling is also rationally used by means of a double facade.
All energy processes are synchronised with each other; the building acts as an intelligent organic whole, which responds to external conditions and adapts to user preferences. By automatically rationalising the processes, the building continually increases its savings.
