This paper focuses on scissor like deployable/retractable structures that can be used for civil engineering and architectural applications. A general outline of deployable structures is given through the principals of different succeeded examples, namely manually locking deployable structures stabilized by cables, self-locking deployable systems and adaptive structures like retractable domes. Undergoing research tends and the perspectives of these structures will be discussed with a special emphasis on potential qualities favoring sustainable development. This novel aspect envisages a future adaptive and dynamic architecture that enables a reduced level of energy consumption, ameliorated occupant comfort and better optimization of space use.

Visegrád, with its 1800 inhabitants, is considered to be the smallest town of Hungary. The development of the town center is a fine example for how the original exaggerating ideas were altered due to the economic crisis - besides its negative effects - and facilitated the birth of a sustainable development, satisfying the continuous needs of the local community and the temporary demands of tourism.

Counties of Hungary (with special focus on Zala) were studied based on two different parameters of waste management: the extensiveness of waste collection and the amount of waste per capita. Other indicators were also examined, which may be related to the amount of waste per capita such as GDP per capita or educational level in the area. It was found that the former might have a positive correlation, while the latter indicates only a weak correlation. Based on the conclusions the waste collection is expected to be further improved in Zala County, while probably increasing pressure will appear on waste recovery matter.

The management of an urban context in a Smart City perspective requires the development of innovative projects, with new applications in multidisciplinary research areas. They can be related to many aspects of city life and urban management: fuel consumption monitoring, energy efficiency issues, environment, social organization, traffic, urban transformations, etc.

Geomatics, the modern discipline of gathering, storing, processing, and delivering digital spatially referenced information, can play a fundamental role in many of these areas, providing new efficient and productive methods for a precise mapping of different phenomena by traditional cartographic representation or by new methods of data visualization and manipulation (e.g. three-dimensional modelling, data fusion, etc.). The technologies involved are based on airborne or satellite remote sensing (in visible, near infrared, thermal bands), laser scanning, digital photogrammetry, satellite positioning and, first of all, appropriate sensor integration (online or offline).

The aim of this work is to present and analyse some new opportunities offered by Geomatics technologies for a Smart City management, with a specific interest towards the energy sector related to buildings. Reducing consumption and CO2 emissions is a primary objective to be pursued for a sustainable development and, in this direction, an accurate knowledge of energy consumptions and waste for heating of single houses, blocks or districts is needed.

A synoptic information regarding a city or a portion of a city can be acquired through sensors on board of airplanes or satellite platforms, operating in the thermal band. A problem to be investigated at the scale

A problem to be investigated at the scale of the whole urban context is the Urban Heat Island (UHI), a phenomenon known and studied in the last decades. UHI is related not only to sensible heat released by anthropic activities, but also to land use variations and evapotranspiration reduction. The availability of thermal satellite sensors is fundamental to carry out multi-temporal studies in order to evaluate the dynamic behaviour of the UHI for a city.

Working with a greater detail, districts or single buildings can be analysed by specifically designed airborne surveys. The activity has been recently carried out in the EnergyCity project, developed in the framework of the Central Europe programme established by UE. As demonstrated by the project, such data can be successfully integrated in a GIS storing all relevant data about buildings and energy supply, in order to create a powerful geospatial database for a Decision Support System assisting to reduce energy losses and CO2 emissions.

Today, aerial thermal mapping could be furthermore integrated by terrestrial 3D surveys realized with Mobile Mapping Systems through multisensor platforms comprising thermal camera/s, laser scanning, GPS, inertial systems, etc. In this way the product can be a true 3D thermal model with good geometric properties, enlarging the possibilities in respect to conventional qualitative 2D images with simple colour palettes.

Finally, some applications in the energy sector could benefit from the availability of a true 3D City Model, where the buildings are carefully described through three-dimensional elements. The processing of airborne LiDAR datasets for automated and semi-automated extraction of 3D buildings can provide such new generation of 3D city models.
