The design of a building , a house or a home, in general, plays a key role in guaranteeing adequate quality of the building constructed and so that it meets the standards established by legislation and is sustainable throughout its useful life. , both in the environmental and economic spheres. Table of Contents Reference regulatory framework Manufacturing cost and operating cost The influence of ventilation on design Reference regulatory framework Regarding regulations, we can say that the reference document is the Technical Building Code (CTE), which includes in its different basic documents the requirements and references to numerous European and international standards. The CTE is the fundamental pillar of building planning in Spain and is born as a result of the Building Planning Law (Law 38/1999, of November 5). The CTE acts as an element of harmonization and transposition of European directives. The last major reform has taken place due to the transposition of Directive 2010/31/EU, relating to energy efficiency in buildings. This regulation is much more demanding and ambitious than the previous one in terms of energy savings and efficiency in buildings, both recently built and existing ones.
Manufacturing cost and operating cost As a result of the legislation cited above, a new concept of building design arises that focuses on achieving the lowest possible cost of manufacturing and construction of the building, mainly through the choice of materials, but without affecting the life cycle of the building. building. During the operation phase of a home, the accumulated costs represent, depending on the climate, the type of building and the use, between 75% and 30% of the total construction and operation cost. These figures are key to understanding that designing a building with adequate durability criteria India Part Time Job Seekers Phone Number List studying its life cycle is the basis for ensuring the sustainability of the construction. Design strategies focused on reducing energy consumption encompass multiple aspects, such as: Use of free energy (natural lighting, solar radiation, etc.). Bioclimatic construction. Efficient combustion, air conditioning and ventilation systems. Reduction of energy demand, by improving insulation and design criteria. As a result of this design strategy, it may happen that an initial overinvestment leads to very significant economic and energy savings over the years, which is why a design that does not focus only on the construction cost is essential. The influence of ventilation on design Ventilation systems have a key influence on the energy efficiency of the building and, therefore, its energy consumption during its useful life.

However, they also play a determining role in the quality of life inside it. Adequate ventilation ensures levels of comfort and health of the indoor air in accordance with the requirements of the regulations, and avoids structural problems such as humidity or even sick building syndrome. The CTE determines and regulates the criteria and parameters that must be met to guarantee adequate ventilation and indoor air quality in homes. The use of maximum efficiency and comfort systems, based on double-flow mechanical ventilation systems with heat recovery, will reduce the electrical or fuel cost required by the building's air conditioning systems. With a ventilation system that is regulated and controlled by air quality parameters (CO 2 , volatile organic compounds, etc.), it is possible to introduce the exact amount of air from the outside to guarantee health and avoid its excess, since, Being at a temperature and humidity different from those of comfort, it requires high energy consumption to be adequate to the interior conditions. In addition, this air can be previously filtered or treated to eliminate the presence of particles or contaminants from the outside air. To reduce energy consumption as much as possible, heat recovery systems will be installed that have fans driven by highly energy efficient, variable speed motors, which reduces electrical energy consumption to a maximum.
