    1973’te yaşanan Petrol Krizi ile beraber doğal kaynakların kısıtlı olduğu anlaşılmış ve olabildiğince verimli kullanılması gerektiği gündeme gelmiştir. 1980’lerden itibaren ise küresel ısınmanın literatüre girmesiyle beraber “Enerji Etkinlik” günümüzde en gözde olan konulardan bir tanesi haline gelmiştir. Enerji harcamalarında binaların %32’lik gibi büyük bir paya sahip olması ise bina kabuğunun enerji etkin bir şekilde tasarlanması ihtiyacını doğurmaktadır. Bu açıdan ele alındığında en çok tüketilen yapı malzemesi olan betonun ısıl geçirgenlik değerinin düzenlenmesinin binaların enerji etkin tasarımında anahtar rol oynadığı son derece açıktır. Bu nedenle, çalışma beton yapı bileşenlerinin ısıl yalıtım yönünden incelenmesini konu edinmiştir.As one of the most important results of Oil Crisis in 1973 it has been understood that the natural sources are exhaustible and they ought to be consumed efficiently as much as possible. With discussion about Global Warming within the scope of scientific literature since 1980s “Energy Efficiency” became one of the most popular research topics until today. Since the buildings are responsible for 32% of total energy consumption energy efficient design of the building envelopes became more than an issue. As concrete is the most widely used construction material determining its thermal conductivity value by means of different techniques and experimental studies plays key role in energy efficient designing of buildings. Therefore, this study concerns with the evaluation of concrete building elements from thermal insulation viewpoint

    The modeling of energy components in Wireless Sensor Network (WSN) simulation is important for obtaining realistic lifetime predictions and ensuring the faithful operation of energy-aware algorithms. The use of supercapacitors as energy stores on WSN nodes is increasing, but their behavior differs from that of batteries. This paper proposes a model for a supercapacitor energy store based upon experimental results, and compares obtained simulation results to those using an ‘ideal’ energy store model. The proposed model also considers the variety and behavior of energy consumers, and finds that contrary to many existing models, the energy consumed depends on the store voltage (which varies considerably during supercapacitor discharge). Furthermore, energy models in a node’s embedded firmware are shown to be paramount for providing energy-aware operation
