Energy requalification

Design of new buildings with high performance and reduced energy consumption

About it

Through the energy requalification of a building, through the intervention of a team of professionals, specialized in the various fields of application, various advantages can be obtained: Reuse of abandoned buildings through the construction of a new "performance" building envelope. Intervention of recovery of particular existing buildings, through the use of low energy consumption materials and technologies (green roofs, high efficiency windows, sound insulation, etc.). Design of new buildings with high performance and reduced energy consumption or "passive" buildings. Our studio will be in charge of coordinating individual specialists, as well as architectural design and the application of energy saving and eco-sustainable architecture concepts.

Energy saving in buildings

Building according to energy saving criteria allows you to reduce energy consumption for heating buildings, and therefore to avoid the emission of harmful or harmful substances for the climate, such as carbon dioxide (CO2). The savings potential is enormous, if we consider that about half of the total energy needs are absorbed by domestic users, and that about 75% of this need is also used for heating buildings. In new buildings, the energy requirement for space heating can be reduced to a tenth of that of existing buildings. However, it is also possible to drastically reduce the energy requirements of existing buildings by appropriately intervening with adequate renovation works. In particular, it is essential to plan thermal insulation from the early stages of the design of both new buildings and the renovation of old buildings. Energy optimization indexes in buildings: compact artifacts insulation of external walls quality windows avoid thermal bridges watertightness (to air and wind) passive use of solar energy production of efficient and clean heat air conditioning systems with heat recovery reduction of electricity consumption Advantages of energy optimization: decrease in heating costs increase in comfort revaluation of the value of the building contribution to environmental and climate protection Interventions to improve the thermal qualities of a building can be: insulation of the roof insulation of the external walls insulation of the cellar floor replacement of fixtures replacement of the heating system.

Bioclimatic Architecture

Bio-climatic architecture is a targeted approach to the problem of regulating the climate inside buildings based on the premise of working with the forces of nature, not against them, and exploiting their potential to create better living conditions. This can be done to a large extent by properly designing the elements of a building and using them in such a way as to maximize the benefits of solar heating during the winter months, without reducing the desired comfort levels, while trying to avoid the risks of overheating during the winter months. the summer. By placing particular attention on the orientation and shape of the building, on the arrangement of the glass surfaces, on the shadows in the various periods of the year, on the type of insulation, etc ..., it is possible to create a building characterized by drastically reduced energy needs compared to the standard. On the other hand, high levels of thermal comfort can be obtained. Consequently, in conventional construction, the extensive use of heating and cooling systems becomes an indispensable condition for ensuring even minimal levels of livability.

A particularly important aspect is that designing and building a building in a bioclimatic key does not necessarily involve an increase in costs, so the amortization time of any additional investments can be very short. Bioclimatic design techniques can be summarized in two families:

- Passive or direct technologies without the use of technical systems, allow direct exploitation or conservation of solar thermal energy in winter and its dissipation in summer. This is done through insulation, exploitation of the mass and convention, orientation and shape of the building, arrangement of the glass surfaces, shading throughout the year, natural ventilation, etc ...

- Active or indirect technologies transform energy from renewable sources through the use of equipment such as solar thermal panels, photovoltaic panels, wind microgenerators, as well as ventilation systems with heat recovery.

Smart Grid e Smart Cities

A more efficient consumption of energy requires a radical change in its distribution. For this reason, electricity grids are becoming increasingly “smart”, intelligent grids able to communicate by exchanging information on energy flows, thus managing peak demand more efficiently, avoiding electricity interruptions and reducing the load if necessary. These networks allow producers and consumers to interact, to determine in advance the consumption requests and therefore to adapt flexibly the production and consumption of electricity. This basically means creating an infrastructure superimposed on or alongside the electricity grid that connects the self-production plants on the distribution network with the centralized large-scale power plants, exchanging information on the energy produced and regulating the energy dispatching.

A "smart grid" can direct energy to meet various technical needs.

The network can:

• Respond in an optimal way by balancing energy supply and demand.

• Provide data bandwidth, with a very low management cost compared to the band of entertainment services.

• Divide energy islands on a national and continental scale.

• Integrate into a Home Area Network, to interact through various technologies with communicative entities, including intelligent ones, present in the home. The grid is not a single network, but a set of networks, which have the task of connecting different structures of energy producers (which currently manually connect to the national network and organize themselves) on various levels and with automatic coordination . The smart grid increases connectivity, automation and coordination between suppliers, consumers and the network, to better perform the work of energy transmission and distribution. The functions of the Smart Grids:


By using special sensors and automatic control systems to anticipate, identify and respond to system problems, a smart grid avoids or reduces the problems of overload or power interruption. It is planned to use an automatic system capable of learning to identify causes of failure and resolution plans, when network problems are solved with effective strategies.

Consumer participation

Energy consumers can benefit from a reduction in costs, since the energy efficiency resulting from the correct management of a smart grid allows for a significant reduction in management costs attributable to companies operating in the field. Furthermore, with an intelligent network, it is very easy for a consumer to choose their operator and thereby activate competition. It is also easier to feed energy into the grid for those consumers who own small household systems. The opportunity to participate in the management of electricity leads to talk of energy democratization.

Enabling the electricity market

Increasing the possibilities of transmitting energy makes it easier for supplies from different subjects. When selling and producing electricity becomes easier, markets are activated on a different scale and the laws governing energy markets are changed.

Earnings optimization

Smart grids make it possible to reduce some items of infrastructure management costs including losses due to the transit of energy as the consumption of local production is facilitated. On the other hand, there is a greater intrinsic complexity of the protection systems which must take energy flows into account while maintaining the ability to distinguish faults from withdrawals.

Smart Cities

Smart grids will play a key role in the cities of tomorrow because renewable energy sources are increasingly soliciting electricity distribution networks. Smart grids are decentralized and the power they deliver to the grid is highly fluctuating, which is why it is a real challenge to achieve their easy integration. By allowing the adaptation and dynamic reorganization of the network, a smart grid will allow a massive use of these sources. The development of smart grid solutions that allow better communications between electricity generators and users will allow for better management of distribution grid resources, so as to ensure greater grid stability and security of supply.

Urban mobility

On the mobility front, we need to focus on complex traffic management systems in which information can be downloaded from passengers in real time and from multiple sources, up to the intelligent charging systems of electric vehicles.

Building automation

Finally, let's think about the automated building management system. We could save 40% of the world's energy consumption if all buildings were equipped with the most advanced technologies in this field.
