Energy Sources, Part A: Recovery, Utilization and Environmental Effects

In this study, wind characteristics and wind turbine characteristics were analyzed using the wind speed data collected from two different regions of Turkey during a period of 7 years between 2000 and 2006. Monthly mean wind power at heights of 10, 30, 50, and 70 m was found for two different regions of Turkey. Capacity factors and annual energy output from the wind turbines with a capacity of 850, 1,600, 2,000, and 3,000 kW were calculated. The wind turbines of capacity 3.0 MW for Ankara and Polatli stations were found to produce an energy output per year of 5.9 and 1.8 MW, respectively. Copyright © Taylor & Francis Group, LLC. Source

Environmental Progress and Sustainable Energy

The optimum insulation thickness of the external walls, energy cost savings over a lifetime of 10 yr, and payback periods are calculated for the four different wall types in the city of ElaziǦ, Turkey. The net energy cost savings is calculated by using the P 1-P 2 method. According to the results, the optimum insulation thickness has been obtained by using coal as the energy source and stropor as the insulating material. The results show that the optimum insulation thicknesses vary between 4.5 and 16.5 cm, energy cost savings vary between 14 and 22 $/m 2, and payback periods vary between 1.5 and 2 yr depending on the wall type. The highest value of energy cost savings is reached for the Wall III, which has a composite structure called a sandwich wall. The emissions of CO 2, SO 2, CO, and NO x from the combustion of coal are calculated for the four different wall types. It has been determined that when the optimum insulation thickness is used for coal as an energy source in ElaziǦ, the CO 2 emission rates of fuel vary between 8.3 and 9.3 kg/m 2 yr and the SO 2 emission rates of fuel vary between 0.017 and 0.019 kg/m 2 yr depending on the wall type. The emissions of CO and NO x are reduced by 82% by applying this optimum insulation thickness. © 2010 American Institute of Chemical Engineers. Source

ERACOBUILD aims at strengthening and enlarging the strategic networking of RDI programmes in the field of construction and operation of buildings initiated in the previous ERABUILD coordination action. ERACOBUILD gathers 34 programme owners or managers coming from 17 EU Members States, 4 Associated Countries and 1 European Region. The new countries will benefit from the experience and results of the 15 programmes owners/managers (10 countries) which already launched 6 joint calls in ERABUILD and agreed on two future trans-national programmes on Sustainable renovation of buildings and Value driven construction process to be implemented in ERACOBUILD. New topics for joint activities will also be developed in ERACOBUILD, such as the identification of other RTD priorities especially, but not only, in relation to industry needs, pre/co-normative research and the optimal use of existing research facilities and the development of new ones. Joint activities (studies, clustering, calls for proposals) will be implemented in these new fields in parallel to the trans-national programmes. ERACOBUILD is organised around 6 Work Packages. WP1 deals with the strategic guidance of the project and offers a platform to national funding bodies to share strategies. It is the core for improving cooperation and setting the basis for long-lasting cooperation in the field of construction and operation of buildings. WP2 focuses on the preparation of the joint activities (including a future ERA-NET\) and thus supports the creation of a strong trans-national RDI community in the field. WP3a and WP3b implement the joint activities, respectively in the two trans-national programmes and the new topics. WP4 continuously supports the improvement of the joint activities through a well structured learning and improving process. WP5 deals with communication and dissemination aspects, while contributing to improving the research culture in the sector. WP6 deals with the management.

Renewable and Sustainable Energy Reviews

This paper analyses the potential and the feasibility basis for the wind energy resources in some locations of coastal regions of Turkey. The dominant wind directions, the mean values, wind speeds, wind potential and the frequency distributions were determined. The results showed that Balikesir and Çanakkale among annual averages show higher value of mean wind speed. The mean annual value of Weibull shape parameter k is between 1.54 and 1.86 while the annual value of scale parameter c is between 2.52 m/s and 8.34 m/s. A technical assessment has been made of electricity generation from four wind turbines having capacity of 600 kW, 1500 kW, 2000 kW and 2500 kW. The yearly energy output and capacity factor for the four different turbines were calculated. © 2010 Elsevier Ltd. All rights reserved. Source

Journal of Porous Materials

In present work; epoxidized soybean oil (ESO), fly ash (FA) and natural clay (C) are used to produce 45 kinds of biocomposite materials and by analyzing the physical-mechanical properties of these novel materials, their use as an insulation material is investigated. The compressive strength, tensile strength, abrasion loss, thermal conductivity and oven-dry mass of each sample are measured. The minimum thermal conductivity of 0.273 W/mK is observed with the samples containing ESO-FA-C. It is increased with the decrease of ESO and FA. The compressive and tensile strengths are varied from 13.53 to 6.31 MPa and 1.287 to 0.879 MPa, respectively. © 2010 Springer Science+Business Media, LLC. Source
