“…Level of reduction is feasible in terms of ECMs commonly based on optimum insulation thickness. Similar studies point out a range between 13 and 30% improvements in overall annual energy consumption, depending on different pre-determined measures [33,34,42,43].…”

a b s t r a c tEnergy-efficient retrofits include improvement of building envelope via insulation, employment of building integrated renewable energy technologies, and climate control strategies. Building envelope improvements with insulation is a common approach, yet decision-making plays an important role in determining the most appropriate envelope retrofit strategy. In this study, main objective is to evaluate and optimize envelope retrofit strategies through a calibrated simulation approach. Based on an energy performance audit and monitoring, an existing building is evaluated on performance levels and improvement potentials with basic energy conservation measures (ECMs). The existing building is monitored for a full year and monitoring data is used in calibrating the simulation model. In order to obtain a better-performing building envelope three retrofit strategies including several ECMs are proposed. Retrofit strategies are simulated through calibrated base-case model, and results are evaluated according to changes in indoor environmental parameters and annual energy consumption measures. The analysis of results indicated that pre-assessed strategies yield close results. Therefore, a more comprehensive evaluation based on different decisive criteria is used in optimization of the final retrofit strategy, with the intention to evaluate the effect of individual ECMs on annual end-use energy consumption and investment.

Abstract-This paper is about commercial buildings energy consumption survey (CBECS) benchmarking database consept, its applications and related applications in Turkey. CBECS is useful for energy efficiency in new commercial building constructions, which is a key target to control and lower U.S. nation-wide energy use.Determining energy consumption of buildings is a key target for energy efficiency. Building energy efficiency is crucial especially for economical and climate change concerns. Improving energy efficiency in commercial buildings is useful in order to decrease energy use, owner operating costs, and carbon footprint of the buildings.The aims are to estimate life-cycle energy savings, cost performance of energy efficiency and carbon emission reduction in new commercial buildings utilizing an integrated design, and estimate results. Obtaining energy consumption of buildings can be utilized to decrease energy usage in new commercial buildings by 20-30% on average and up to over 40%. Thus, improved efficiencies permit smaller, cheaper HVAC equipment usage.

“…Yılmaz (2009) studied energy consumption values and CO 2 emissions in model buildings and compared specific alternative solutions related to architecture and mechanical infrastructure. Eskin et al (2007) studied the effects of climatic conditions, thermal insulation, building orientation, exterior colour and window systems on energy consumption. Kılıçlı (2012) studied energy consumption of a sample building and elaborated on improvements that could be made on the building to reduce energy use.…”

5 Türkiye'de kentleşme sürecinde plansız yapılaşma ve bina yapım maliyetlerinin düşük tutulması gibi unsurlar konut binalarında enerji tüketiminin Avrupa Birliği ülkeleri ortalamalarının iki katı gerçekleşmesine neden olmaktadır. Bu gidişat karşısında Türkiye'de 2007 yılından itibaren Enerji Verimliliği Kanunu ve Enerji Performans Yönetmeliği uygulamaya konularak, mevcut konut binalarının enerji tüketimi-kabuk ilişkisindeTurkey has undergone inadequate development during a process of rapid urbanization and growth since the 1950s, parallel to reduced construction costs for residential buildings. This has contributed to household energy consumption in Turkey growing to twice the global average, and twice the averages of European Union member states. In response, the Energy Efficiency Law and other energy performance regulations were enacted in 2007. As a part of "Assessing the Inventory for Renewable Energy Utilization in Existing Residential Buildings and Setting Up Local Design Parameters," supported by the Yıldız Technical University Scientific Research Projects Coordination Department, İstanbul's Beykoz District was chosen as the case area. Using solar energy for heating purposes is popular in Beykoz for a number of reasons, including the prevalence of mostly detached buildings and abundant green space, as well as less building density and fewer stories, compared to the city center. Four buildings were studied in order to identify improvements that would allow for a reduction in cooling and heating loads in existing residential buildings in the context of building envelopes. Research of the four existing residential buildings executes similar results. Results of the study of a multi-family residential building in the neighborhood of Kanlıca is presented. Determined by the calculation of cooling-heating loads and carbon emissions, improvements designed to efficiently utilize solar energy where the building envelope permits are identified. These improvements address window space, eaves, and characteristics, as well as exterior wall insulation thickness, draft prevention, shading, landscaping features, and control of solar energy. Average monthly and annual heating-cooling requirements were calculated using IESVE simulation software. The improvements yielded a 72% drop in annual heating energy consumption and a 24% drop in annual cooling energy consumption, resulting in an average drop of 62% in CO 2 emissions. ARTICLE
