Consumption (from the Union European Union establishes guidelines that promote ECCN, Almost Zero Energy Buildings, or NZEB, for its acronym in English, Nearly Zero Energy Building). Towards a reduction in energy demand The constant increase in the price of energy and increasingly demanding regulatory requirements are increasing the interest on the part of contractors, architects, engineers, owners and other building occupants in the concept of energy efficiency in buildings . How can we ensure that our ventilation and air conditioning system reaches the desired energy efficiency levels? In accordance with the Guide on Building Energy Demand Management, from the Energy Foundation of the Community of Madrid (FENERCOM), it is necessary to comply with the following indications: Guarantee that the heating and cooling energy generated meets the real needs of each moment. Make efficient use of heating and cooling "at no cost", taking advantage of solar and terrestrial energy, and the effects of night ventilation and cooling. Ensure that energy (heat and cold) is distributed efficiently throughout our building, and minimize losses. Try to use, as far as possible, renewable energies. If fossil fuels are use.

An energy source, try to achieve the highest possible efficiency (low temperature boilers). Establish an optimal adjustment in the case of existing ventilation and air conditioning installations. Try to reduce the electricity consumed by ventilation and air conditioning systems, using recirculation pumps, fans, etc. The Regulation with the Regulation of Thermal Installations in Buildings ( RITE , 2007) also i ndicates that we must select both Chinese Overseas Africa Number Data the equipment for generating heat and cold, as well as those intended for the movement and transport of fluids, based on their ability to ensure that their performance are as close as possible to its maximum performance regime, whatever its operating condition. Intelligent control of your ventilation and air conditioning system The implementation of modern and intelligent control technology on our ventilation and air conditioning systems can translate into great energy savings, especially in commercial buildings. By optimizing the control parameters of the systems (replacing classic control algorithms with innovative, highly efficient energy-saving solutions, for exam



Energy savings of up to 15% can be obtained. Given the costs, in most systems only heating control systems are used with control of the fluid temperature depending on the external conditions. To reduce the disadvantages of controlling the interior temperature of a building based on the exterior temperature, it is essential that the control technology implemented maintains the fluid temperature set point at the lowest possible level. There are special controllers on the market that achieve this by automatically adapting the heating curve (which, in turn, adapts to the building). This control of the ventilation and air conditioning systems based on the climate also makes it impossible to record the influence of the sun's radiation, the heat generated by electronic equipment or the occupation of the premises (it is estimated that each person that occupy a room generates, through its own metabolic activity, about 60-100 W of thermal energy). The regulations (RITE, 2007) require that facilities have all necessary regulation and control systems so that the design conditions provided for in air-conditioned pre.
