EFFICIENCY ENERGY AND SUSTAINABILITY
In case of the new design even the remodelling of a large public building as a hospital and other buildings, we could summarize it from a practical point of view the combination of the following sections, without increasingthe Budget in a considerable way:
A bioclimatic building reduces the need for heating and cooling (we can even regulate its internal temperature by using yards) since it is designed so that it obtains the highest and best performance of its location, the climate in which it is located and its orientation. As a result, energy consumption of the building is reduced. Bioclimatic strategies can be combined with the use of renewable energy sources.
In case of hospitals, the cogeneration is considered as one of the leading technologies for buildings that want to register savings in energy consumption. Understood as the simultaneous production of heat and electricity through the use of natural gas that converts water into vapour, and in turn it drives a turbine of power generation, cogeneration is fulfilling its role in many hospitals in Europe, especially in France, UK, Netherlands, Spain, Germany, Portugal and Italy, which get savings of up to 50 percent of electric power.
If obtaining geothermal energy is added to it, obtained from the heat generated in the centre of our Earth, this allows developing and at the same time complementing other systemsthat use renewable energies, able to supplya large part of the building, which we can generate almost self-sufficient buildings from the energy point of view.
The use of different designs in facilities, complemented with low energy lighting, proper design of the domotic system, that are coordinated by sensors and automation control systems in certain facilities provides comfort and energy savings.
In addition, and if this were not enough, the negative effects are reduced that construction has on the environment, with materials involving energy savings, which have a long-term duration and requiring very little maintenance, so that is a considerable saving in time, for example, the use of fireproof vinyl rooms and corridors and patients rooms, suspended ceilings in corridors for the maintenance of the facilities, are being standardized both in materials and measures.
Finally we might add the use of natural or synthetic green roofs. In addition to providing an additional living space, the green roof has many other environmental and economic benefits, such as prolonging the life of the cover, reducing noise and pollution, water retention, energy saving or improving climate and the urban landscape.
