Cities are responsible for about 30% of the energy consumed worldwide. Since 2007 more than 50% of the world population lives in cities, and urbanization is still growing. The energy-efficiency of cities is gaining greater importance today. The paper examines the possibilities of energy consumption reduction and optimization in cities. Various urban and architectural tools are described below that affect indirectly and directly the energy balance of cities. The possible ways of using renewable energy sources in cities have been analyzed. Ways and means of their use is analyzed in on-site, nearby and off-site systems.

In recent years, both legislative instruments and market demand drive the construction industry towards high-performing, low-energy consuming buildings. However, without considering the human dimension, technologies alone do not necessarily guarantee high performance in buildings. Occupant behavior is a leading factor influencing energy use in buildings. To investigate and quantify the human dimension in a building’s energy use, an international research study has been launched as part of project ANNEX66, organized by the International Energy Agency using an interdisciplinary framework. The framework is a synthesis of theories from building physics and social psychology including social cognitive theory, the theory of planned behavior, and the drivers-needs-actions-systems ontology for energy-related behaviors. As a research tool, an online survey was designed to collect cross-country responses from office occupants among 14 universities within 6 countries from 4 continents. This paper introduces results and findings of the Hungarian data collection campaign conducted among 207 occupants in 6 universities across the country.

Abstract

Brigittaplatz located in the 20th district of Vienna, which is a mixed culture residential community with various issues. This paper attempts to uncover the existing problems, weaknesses, potential opportunities of the site and explore a set of local interventions to accomplish site regeneration through architectural and landscape measures. Study utilizes two axes to improve and reconnect the public service, green corridor as well as the interactive relationship. All the proposed interventions are not merely public facility renewal but a new functional and social design, which is trying to reactivate the various relationships in the site that can enhance the quality of life and carry over the impact to larger scales. Authors seek a holistic approach to regenerate Brigittaplatz.

Abstract

Skidmore, Owings & Merrill Limited Liability Partnership as one of the best ‘localized’ overseas design companies in China, has participated in more than ten large-scale urban design projects in Wuhan, which has greatly changed the urban image and architectural style of Wuhan. Its space model of ‘grid road system + high-rise building’ replaces the traditional urban pattern of ‘street + residence’, causing huge cultural conflicts and historical rupture. Based on the planning of Wuhan Hanzheng street as an example, this paper attempts to uncover the cause of formation, the motivation mechanism of ‘grid road system + high-rise buildings’ space model, and to explore how Chinese cities realize the urban modernization with Chinese characteristics.
