With the development of technology from past to present, the types, properties and
product range of the materials used in the buildings are quite developed. Therefore, the effects of
climate, environmental conditions and energy consumption cannot be ignored for selecting these
materials used in the buildings. Usage of materials with the same characteristics for buildings to
be built on different climate may lead to adverse effects about energy-saving and green gasses.
Furthermore, the use of the same materials may not be a proper approach even in buildings with a
different purpose. In this study, forecasting of energy consumption and CO2 emission is analyzed
by utilizing artificial neural network structure according to different climate criteria and material
characteristics for public buildings built in recent years. The Effect levels to energy consumption
and CO2 emission of the building materials and the climate criteria are determined for buildings
serving the same using purpose in different climate characteristics. For the study, different pilot
regions where the public buildings are located are chosen according to climatic characteristics and
five different building materials used in these public buildings are taken into account. When the
results compare according to CO2 emission and energy consumption, it was observed that the
conditions which obtain most efficient results are different

In today's urban life, most of the people's time is spent at home or work office. For this
reason, design and selecting of building materials that control heating (H), ventilation (V) and air
conditioning (AC) are essential. The building materials called, in short HVAC, must
simultaneously provide high comfort, low cost and high energy productivity. Furthermore, HVAC
must be appropriately designed to prevent adverse effects on the environment and climate. In this
study, nine different HVAC systems were examined according to nine different criteria over cost,
pollution, comfort and energy which are considered as four main factors in the selection of HVAC
systems. Since some of the criteria for HVAC systems are described as linguistic, it is not possible
to evaluate the systems with traditional methods using crisp values. Therefore, we propose
generalized intuitionistic fuzzy (IF) - rough set models which are a new and flexible method. IFneighborhoods
are formed by using IF-implicator and IF-t norms, and upper and lower
approximations in rough set theory are calculated according to the neighborhoods. Covering-based
generalized IF rough set models are generated by using the approximations and IF-TOPSIS
method. According to the obtained results, we can see that the proposed method is an appropriate
decision-making method which considers the uncertainties in the linguistic expressions for
selecting the most suitable HVAC system.

The wastewater treatment in the textile industry is of special importance due to the
intensive use of chemicals and dyes. However, wastewater treatment plants have impacts on
environmental and these environmental impacts should also be evaluated and minimized.
Neutralization is one of the processes with the huge chemical consumption in the wastewater
treatment plant. Therefore, the chemical alternatives used in the neutralization process should
be compared in terms of their environmental impacts. In this study, the performances of carbon
dioxide and sulfuric acid as two alternative chemicals used in the neutralization process applied
in a textile factory wastewater treatment plant are compared using the life cycle approach. The
neutralization process using carbon dioxide yielded better results in the categories of abiotic
depletion, fossil fuels, ozone layer depletion (ODP), fresh aquatic ecotoxicity, marine aquatic
ecotoxicity, terrestrial ecotoxicity, photochemical oxidation, acidification, and eutrophication.
