It became a common practice to put commercial premises on the ground level of apartment buildings in urban settlements. Such commercial premises hold dancing clubs, fitness clubs, coffee shops and similar businesses which can be treated as sources of noise from music, conversations, social meetings and sport activities. These premises tend to be open in the evening and at night, disturbing local residents. Studies were undertaken to determine noise characteristics in commercial premises located in residential buildings. This paper presents typical entertainment noise spectra and their influence on acoustic insulation of interior partitions. The sound insulation index has been determined on the basis of laboratory tests and recorded sound spectra, in accordance with assessment procedure given in the draft ISO 16717-1 "Acoustics - Evaluation of sound insulation spectra by single-numbers - Part 1: Airborne sound insulation". Presented results may be helpful in designing and adapting the buildings in which commercial services are expected to be situated.

The article presents the major outcome of the European research project BUILDING UP "Multi-stakeholder, Cross-sectorial, Collaborative Long Term Research and Innovation Roadmap to Overcome Technological and Non-technological Barriers towards More Energy-efficient Buildings and Districts". Its major objective is to create an effective coordination of European Technology Platforms and major initiatives in order to identify and review the needs in terms of long-term research and innovation through development of energy efficiency roadmap. BUILDING UP Research and Innovation Roadmap is intended to provide a thorough overview on targets up to 2020 and beyond related to nanotechnologies, materials and processes, necessary to be achieved in order to improve the energy efficiency in the built environment. Discussion, revision and validation of the roadmap were performed through several working group meetings, surveys and participation in conference and public events.

An implementation of the sustainable development idea in the building sector stimulates search for materials and structures providing better heat insulation. Because the acoustical expectations and requirements also rise, a need for harmonization of both parameters increases. The article demonstrates differences between thermal and acoustical behavior of various building elements. The analysis of measurement results obtained for different structures demonstrates that finding a simple relationship between acoustical and thermal insulations is quite difficult. Tendencies observed in each case are rather opposite than parallel and materials or technical solutions that improve thermal resistance of a building partition often deteriorate its acoustic performance. © 2015 The Authors.

The aim of the paper is presenting the acoustical quality assessment index method of the long rooms at the designing stage, which takes into consideration the selection of the architectural and acoustical parameters. The method allow to initial assessment by architects and designer of the long rooms acoustical quality in order to ensure the adequate speech intelligibility (without traffic noise) of the emergency sound systems, resulting from, among the others, the standard requirements. The presented verification results, by subjective speech intelligibility measurements and by STI measurements with sound alarm system application, confirm initially correctness of proposed method.
