Energy Efficient Solutions in Modern Buildings.

In the current days, all over the world paying more attention to the problem of resource conservation on energy efficient use. Saving energy is one of the most actual topic in the current society. In the construction industry, the highest energy saving potentials can be realized by energy efficient building design. The energy efficiency of buildings is significantly influenced by architectural design aspects, such as orientation, shape of the building structure, where the openings of windows are located etc.

              

Energy consumption of buildings, is not significant for the past, but it has become the dominate measure of the quality of the project in the present. If at the beginning of the construction of energy efficient buildings, until the early 1990s, the main interest is the study of measures for the energy saving. Then in the mid-1990s the priority is given to energy to energy efficient solutions that simultaneously contribute to the quality of microclimate.

In most countries buildings account for almost half of the country’s total energy consumption. Increasing population place growing demand in education, health services, residential which requires further renovation of existing buildings and construction new buildings. So these energy efficient building solutions is a safe bat and creates way to prevent from the fluctuation in energy costs. So in the present construction of large number of buildings are constructed based on those different concept of energy efficient solutions. In this article, there is an overview of the most important solutions for energy efficient building designs.

One of those solutions is Climate Design. In other words, designs that can adapt to climate conditions. In history also the building design, besides other factors like social aspects, availability of building materials, always was a result of the climatic conditions on the building site but in the present it is not the same. So, to design energy efficient buildings architectural concepts have to integrate this old knowledge and develop new innovative design solutions based on climatic aspects. Most important aspects with strong influence on the building design are outdoor temperature, solar radiation, humidity and wind. Giving more intention for wind ventilation, using solar-reflecting white coating to roof are some suggestions for it.

Next one is compactness; minimization of losses. In most countries transmission heat losses play an important role for the energy performance of buildings. Depending on the building type (housing, office, schools, etc.) transmission losses can have the highest ratio of all losses. Especially for an economical realization of passive houses or zero- and plus energy- houses compactness is of highest importance, as worse compactness means higher construction costs

Another one is Maximization of solar gains. In heating climates, a maximization of passive solar gains should be the main target to reduce the heating energy demand. Optimized interaction of orientation, size of windows and disposable thermal mass are the key elements to do it. Orientation and size of transparent building elements (windows) have important influence on the cooling demand. Intelligent shading elements with different orientation are further measures for the reduction of solar gains.

One of the most important energy efficient solution in modern buildings is minimization of electricity demand for artificial lighting. Besides heating and cooling the energy demand for artificial lighting is of importance for the energetic performance of buildings. Buildings with huge overall width, like office buildings, tend to have substantial energy demand for artificial lighting. The development of innovative daylight concepts is the most important strategy to decrease the energy demand for lighting. It is important to consider that the daylight concepts always have to be considered in combination with aspects for heating and cooling.

                 

As the technology develops people are seeking for these energy efficient solutions that can adapt the design, operation and management of the modern buildings and it became an important part of sustainable development.
