When analysing the primary issues cities face in becoming smart cities, the topic of building energy efficiency should be addressed, taking into consideration the basic distinctions between new buildings (those being built now and, in the future,) and the current building stock (all buildings that are found in cities today).
The ability of a system to exploit the energy supplied to it to meet its requirements is referred to as energy efficiency. The better the energy efficiency, the lower the fuel consumption is about the fulfilment of a certain requirement.
The term "energy efficiency in buildings" refers to all of the programming, planning, design, and construction actions that enable you to achieve the primary goal of saving energy.
A sustainable intelligent building brings together all of the aspects that contribute to high energy efficiency and automation to meet the European Union's 2020 goals. The goal is to get 17% of production from renewable energy sources by 2020, and 20% of primary energy by 2050. The term "smart" refers to the ability to manage technology inside a building in a simplified manner. Smart technology must combine systems and automation, be programmable and configurable, and be able to expand with technological advancements.
Furthermore, today's buildings must be interconnected: there must be the ability to centrally manage the amenities, both locally and remotely.
LEED (leadership in energy and environmental design) certification
Climate change and resource scarcity are the two most pressing issues of our day. Furthermore, many countries around the world rely on imported energy; in the EU, for example, imported energy accounts for 50% of total energy consumption today, with that proportion anticipated to rise to 70% by 2030. LEED certification has been proved in recent research to have a favourable financial impact on the value of a building.
As a result, including LEED certification as part of a strategy makes sense if a building owner is modernising systems and wants to add financial value. System upgrades are an important aspect of LEED certification for existing buildings (which focuses on operations and maintenance). Much of what is commonly offered as an existing building approach can meet some of the LEED criteria. LEED certification for existing buildings also necessitates addressing concerns such as recycling, external care programmes, and cleaning and maintenance difficulties in addition to system upgrades. Building a sustainable or green building and integrating a building's technology systems have a lot in common.
It's all about resource efficiency, life-cycle effects, and building performance when it comes to green buildings.
Construction and operating efficiencies and improved management and occupant functions are all goals of smart buildings, which are based on integrated building technology systems. Because of the tighter control system integration, a smart building will provide energy control and cost savings beyond that of traditional systems installation. The financial and environmental benefits of energy management are delivered by smart and green buildings. Learning smart buildings, or the use of computer and telematic tools in an integrated project with automation organised systems and passive bioclimatic strategies in architecture establishes socio-technical management of intelligent buildings, in which the technological and human factors work together to define sustainable intelligent buildings and smart home automation.
Discussing intelligent buildings entails proposing new active envelope solutions that can reduce the carbon footprint of construction systems; architectural integration of having to build advanced screen envelopes capable of ensuring good lighting, thermal regulation, and energy generation, in addition to the basic operations of water and temperature protection. The creation of a modular system that allows for differential architectural aesthetic solutions regarding the designer's needs while maintaining the facade's geometrical consistency; the integration of renewable energy technology and its ability to guarantee variable thermo-hygrometric performance in relation with the outside climate.
An intelligent building is, in which artificial intelligence is embedded into the shell to attain high levels of energy efficiency and thus environmental sustainability. Bringing the smart building to a purely technological matter is certainly simplistic when you consider that it fits into a smart city that develops networks of human relations, sustainable mobility, and energy efficiency improvements.
