decision making criteria for optimal selection of innovative daylighting systemsin buildings, using integrated delphi/dematel/ahp approach

Nowadays, dense cities have led towards the decrease of daylight penetration into the interiorspace. daylight crisis in buildings brings significant challenges to architecture, in three domains ofeconomic, health - wellbeing and environment. light well as one of the most common means ofdaylight tolls in building, experiences severe limitations and requires special attention. the question iswhich strategy is the best for increasing the daylight penetration to the depth of buildings. one of themain challenges in deep plan is to guide daylight into the building core and this can be performed throughdaylighting strategies, but the choice of the proper innovative daylighting system (ids) with severalparameters is the problem. this paper aims to find elements for optimal choice and selecting contextcompatibletools for light well. the result shows that four macro factors were found at the interaction ofbuilding and ids. identifying the integration components can play an effective role in decision-making ordesign a new tolls consistent with the physical conditions of light well and building to overcome thedaylight crisis. the present study aimed to identify, evaluate, and weigh the factors affecting the selectionof appropriate and innovative daylighting systems for buildings. to this end, a three-phase study wasplanned and carried out. in the first phase, the factors affecting the selection of daylighting systems forthe building were screened and finalized by using the delphi method in three steps. in the second phase,interactions between criteria and sub-criteria were evaluated by the dematel technique and then thenetwork of communications and significant relationship between them were determined. the analytichierarchy process (ahp) was employed in the third phase to evaluate the criteria and determine theirimportance in the selection of daylighting systems. finally, the relevant sub-criteria were extracted andprioritized. the results indicated that structural, economic, and technical criteria were more effective thanfunctional criteria in the selection of daylighting systems for buildings.
