Abstract: Different types of compound radiant floor heating systems are used in residential buildings and their thermal and economic performance varies largely by many factors. One of the most influential factors on performance of a system is envelopes insulation. The aim of this study was to investigate the effect of insulation in thermal and economic performance of a radiant floor heating system. Using different insulation approaches – poor or no insulation, conventional insulation according to national regulations and with BioPCM boards- heating loads and system sizing's were analyzed and calculated by Design Builder software and system and components were compared in each case. The results showed that the heating loads and component sizes decreased significantly with PCM insulation. As a result, using BioPCM boards for envelope insulation can be considered as an energy and money saving constructing approach for a residential buildings using radiant floor heating system. Due to it’s at least

Abstract: n the present research, the designation of corrugated steel web beams is formulated as optimum design problem. The minimum weights of these new generation steel beams are taken as the objective functions while the design constraints are respectively implemented from BS EN1993- 1:2005 (Annex-D, Eurocode 3) ve DIN 18-800 Teil-1. Firefly and hunting search stochastic optimization techniques are used for obtaining the solution of the design problem. The thickness and height of web, distance between the peaks of the following two web curves, the width and thickness of flange will be considered as the problem design variables. The formulation of the design problem considering the limitations of the above mentioned turns out to be a discrete programming problem. Number of design examples considered to demonstrate the efficiency of the algorithms.
