The Slovak building environmental assessment system has been processed. The main fields and relevant indicators are proposed on the base of available experience database analysis from environmental, social and economic performance of buildings. The existing systems and methods used in many countries were the base of new system development. The developed building environmental assessment system (BEAS) deals with evaluation of site selection and project planning, building construction, indoor environment, energy performance, waste and water management. The aim of paper is introduced the BEAS developed in Slovakia. The paper also presents the evaluation of selected office buildings in the phase of their conceptual design.

The new approach of sustainability assessment of buildings requires the quantification of impacts and aspects for the environmental, social and economic performance of buildings using quantitative and qualitative indicators. These indicators are included in building environmental assessment systems and tools used in different countries for evaluating the integrated building performance. The building environmental assessment system (BEAS) has been developed in Slovakia as well through the last years. BEAS as a multicriteria system includes environmental, social and cultural aspects which are incorporated in proposed main fields: site selection and project planning; building construction; indoor environment; energy performance; water management and waste management. The aim of paper is the identification and determination of weights of fields in BEAS. Eleven experts participated in the study. Consequently the order and weights of significance of main assessment fields was determined.

Nowe podejście do oceny zrównoważonego charakteru budynków wymaga obliczenia wpływów i aspektów środowiskowej, społecznej i ekonomicznej wydajności budynków z zastosowaniem wskaźników ilościowych oraz jakościowych. Zostają one włączone w systemy i narzędzia środowiskowej oceny budynków wykorzystywane w różnych krajach dla oceny zintegrowanej wydajności budynków. W ostatnich latach system środowiskowej oceny budynków (ang. BEAS) opracowywano również na Słowacji. BEAS jako system wielokryterialny obejmuje aspekty środowiskowe, społeczne i kulturowe włączane do proponowanych domen głównych, takich jak: wybór terenu budowy, planowanie projektu, konstrukcja budynku, środowisko wewnętrzne, wydajność energetyczna, zarządzanie wodą oraz odpadami. Celem niniejszego artykułu jest identyfikacja i określenie znaczenia poszczególnych czynników BEAS. W opracowaniu udział wzięło jedenastu ekspertów. W rezultacie ustalono porządek i znaczenie głównych dziedzin oceny.
The paper aimed at an assessment of environmental and energy impacts of designed family house using green technologies. Investigated buildings are located in Kosice region. The analysis investigates the role of applied green technologies in proposed variants of family house from embodied energy and equivalent emissions of CO2 and SO2 by using LCA assessment method within “cradle to gate” boundaries. The main contribution of the study is underlining that green technologies have significant part in the reduction of the environmental and energy impacts.

Almost each country has potential for ensuring the sustainability of its economy if it avails itself of the opportunities offered by a nationally customized green economy strategy. To move towards a green economy, it will, however, have to introduce innovative technologies, techniques and processes. In particular, it will have to modernize its obsolete production and transport infra-structures and construction and cultivation methods. Green technologies can also contribute to the green economy because they have the potential to create new business opportunities, markets and jobs. This paper i) reviews the main environmental challenges and opportunities for the greening of the Košice region economy; ii) assesses the country’s innovation policies and the challenges and opportunities for the introduction of green technologies; iii) provide policy recommendations on adopting and applying innovative green technologies more efficiently. The strategy for adopting and applying innovative green technologies, also in Košice region, should carefully consider the current status of policy measures, challenges and opportunities which the country faces. Success depends not only on the improvement of each individual sector in region, but also on how these separate elements interact. Therefore, a wide range of consultations and interactions with stakeholders, such as the government authorities, business community, civil society, academics, researchers, scientists, financial institutions, etc., are essential to facilitate this interaction.
