Re-thinking of energy consumption classification by the patterns of occupant behaviour in dwellings: A conceptual framework
(Free University of Bozen Bolzano, 2015) Harputlugil, G.U.; Harputlugil, Timuçin; Harputlugil, T.; 40295; 36110; Mimarlık
The aim of this paper is to present the conceptual framework of a TUBİTAK funded project titled "Developing a New Methodology to Improve Housing Quality in Turkey Based on Effects of Occupant Behavior on Energy and Comfort of the Dwellings". Although the objective of the project is the development of new methodologies and tools to be used for the definition of effects of behavior profiles of housing occupants on the energy consumption and usage of this knowledge for building new houses and renovation of existing buildings, here the first step of research has been executed. By defining sensitivity of occupant behavior on energy consumption, it is planned to classify different models of occupant behavior. With data provided, the aim is to develop an "occupant behavior labeling" which rates occupants instead of buildings. To provide the mentioned data, sensitivity analysis of existing occupant behavior will be analysed based on the Monte Carlo Methodology. This methodology is one of the most used methodologies to analyse accurate distribution of possible outputs relied on inputs based on probability. Inputs for this research are (1) number of occupants for each space (for weekdays and weekend) (2) behaviour for ventilation (Window open/closed and mechanical ventilation on/off) (3) control of heating systems (radiator on/off and/or thermostat degree). These data will be provided with survey and data logging of chosen a house occupant group. As a consequence of the research, the aim is not only to rate the behavior of housing occupants but also determine occupancy groups/labels. With this approach, based on occupant's behavior labeling, the aim is to realize fast and affective applications for renovation of existing buildings. Moreover, by evaluation/assessment of houses which will be designed in the future based on determined occupant profiles allow to produce high performance dwellings. © 2015 by Bozen-Bolzano University Press Free University of Bozen-Bolzano All rights reserved.
An investigation on The Effect of Drawing Techniques towards Students’ Performance and Perception in Architectural Education.
(2018) Harputlugil, Timuçin; Çankaya Topak, Sıla; Özkan Öztürk, Nur; 40295; 272044; 257557; Mimarlık
Emerging technologies allow digital production to be used within the initial stages of architectural design. The design process, in which drawing is the main tool, is affected with the rapid increase of digital production in the building sector and increasing awareness on digital drawing and production/fabrication is an undeniable fact of 21st century. In this context, the article investigates the status of hand (manual) and computer (digital) based drawings in architectural education; the students' perceptions and its effects on their performances. A case study -within the context of the Construction Systems II course given at the Architecture Department of Çankaya University-has been conducted to evaluate/quantify the students’ perceptions in order to demonstrate the advantages and disadvantages of hand and computer based drawings. Positive correlations of the familiarity to the drawing tool with easy correction of mistakes and relation of familiarity to the drawing tool with time management is observed. Based on the research; there is not a significant difference between hand based or computer based tools regarding spent time for the work in student practices; however, the process regarding revision, correction, or composition of drawing decreases time spent in computer aided drawing. Consequentlyit has been noticed that as the capability in drawing tool increased, the class performance of students increased too. The outcomes of the case study based on observations, evaluation, questionnaires and analysis covering an academicterm, are discussed in detail within the scope of the article.

The interaction between humans and buildings for energy efficiency: A critical review
(Elsevier, 2021) Harputlugil, Timucin; Harputlugil, Timuçin; de Wilde, Pieter; 40295; Mimarlık
Buildings consume energy for different purposes. One core function is to provide healthy and comfortable living conditions for the humans that inhabit these buildings. The associated energy use is significant: taken together, buildings are responsible for roughly 40% of the world's total annual energy consumption. This large percentage makes the built environment an important target for researchers, policy makers, innovators and others who aim to decrease energy consumption and the associated emissions of Greenhouse Gases (GHG). Unfortunately, the significant body of research on energy efficient buildings conducted since the 1970s has had only a limited impact on the overall energy use of the sector, and this remains a serious concern. The energy use of buildings shows a strong correlation with the activities of the building occupants. A key factor that makes it hard to curb building energy use is a lack of understanding of building occupant behaviour. This paper reviews research on building occupant behaviour in two stages. The first stage reviews important issues, milestones, methodologies used, building types analysed and progress achieved related to the topic, as reported in the most frequently cited papers. The second stage focuses on recent work in the area and investigates `state of the art' developments in terms of questions asked and solutions proposed. The aim is to identify problems and knowledge gaps in the field for future projection. Recent research on the topic is analysed, taking account of methodologies, building types, locations, keywords, data sampling and survey size. Based on a critical analysis of the literature, the following outcomes can be reported: research on building occupant behaviour relies strongly on quantitative methods, but studies are mostly located in the northern hemisphere and in developed and high-income countries. The dominant research topics associated with occupant behaviour are energy demand and thermal comfort, followed by retrofit and renovation. Most research focuses on technical aspects rather than socio-economic issues. Current research is mostly limited to studies of single buildings and typically lacks data-gathering standards, which makes it hard to conduct cross cultural data comparisons. Most research concentrates on individual topics, such as window, door and blind adjustments, effects of Heating Ventilating Air Condition (HVAC) systems etc. and does not provide a wider, holistic view that can be linked to social and economic factors.
Identifying Critical Success and Risk Factors of Airport Projects in Turkey Based on Public-Private Partnership
(2019) Harputlugil, Timuçin; Harputlugil, Timuçin; 40295; Mimarlık
Public-Private Partnership (PPP) is a significant procurement method for providing public service; in particular, for airport projects which constitute the most capital-demanding infrastructures with high level of risks. . Following extensive systematic literature review, Critical Success Factors (CSF), and Risk Factors (RF) were gathered based on a questionnaire for professionals and experts for PPP airport projects in Turkey, 162 experts of which 67 of them responded. Key Performance Indicators are grouped with factor analysis test based on the most important CSFs and risk factors identified within the scope of the paper.

CONCEPTUAL FRAMEWORK FOR A DECISION-MAKING MODEL BASED ON THE ANALYTIC HIERARCHY PROCESS (AHP) TO SELECT THE BEST PUBLIC PRIVATE PARTNERSHIP (PPP) MODEL FOR AIRPORTS
(New Zealand Acad Applied Research Ltd, 2017) Mohammed, Ali Omar; Harputlugil, Timuçin; Harputlugil, Timucin; 40295; Mimarlık
The adoption of public-private partnerships (PPPs) as a strategy for infrastructure projects, such as airports, highways, bridges, water supplies, and telecommunication, has been implemented in developed and developing countries with a number of obstacles. Based on this stance, critical success factors (CSFs) of public-private partnership projects and the selection of appropriate PPP models are critical issues that need to be analyzed. A multidisciplinary review of the literature on the critical success factors of public-private partnerships projects reveals the lack of a comprehensive decision-making model for selecting an appropriate PPP model. This paper presents a conceptual framework for a decision-making model to select the best PPP model considering CSFs for developing countries. The model is expected to be used for infrastructure projects, mostly for airports. The decision-making model is structured on the Analytic Hierarchy Process and sensitivity analysis. The decisionmaking model is expected to be adopted as a tool and contribute to decision makers for selecting the best fit PPP model for airports in order to enhance projects successfully.
Conceptual framework for potential implementations of multi criteria decision making (MCDM) methods for design quality assessment
(2011) Harputlugil, Timuçin; Prins, Matthijs; Gültekin, A. Tanju; Topçu, İlker; 40295; Mimarlık
Architectural design can be considered as a process influenced by many stakeholders, each of which has different decision power. Each stakeholder might have his/her own criteria and weightings depending on his/her own perspective and role. Hence design can be seen as a multi-criteria decision making (MCDM) process. Considering architectural design, its evaluation and quality assessment within a context of MCDM is not regularly performed within building processes. The aim of the paper is to find/adapt proper methodologies of MCDM, used in other domains for assessment of design quality, adapt them to the construction domain and test their applicability. Current tools (for instance DQI, DEEP, AEDET, HQI, LEED, BREEAM, BQA) for quality assessment will be reviewed and compared with several MCDM methods (ie. AHP, ANP, PROMETHEE, SAW AND TOPSIS). Advantages and disadvantages of gathered outcomes from comparisons for assessment and applicability within architectural design will be discussed. Finally reflections on the outcomes will be provided.

Reflections on the Evidentiary Basis of Indoor Air Quality Standards
(Mdpi, 2022) Berger, Christiane; Harputlugil, Timuçin; Mahdavi, Ardeshir; Azar, Elie; Bandurski, Karol; Bourikas, Leonidas; Harputlugil, Timucin; Schweiker, Marcel; 40295; Mimarlık
Buildings are expected to provide healthy and comfortable indoor environmental conditions for their users. Such conditions have diverse dimensions, including thermal, visual, air quality, auditory, and olfactory aspects. Indoor environmental quality standards, guidelines, and codes typically inform professionals in the building design and operation phase in view of procedural, contractual, and legal boundary conditions. Given this critical role of standards, it seems significant to examine the applicability and scientific validity on a regular basis. In this context, the present paper focuses on the standard-based definition of indoor air quality (IAQ) indicators and their respective values. Hence, the main aim of this effort is to study several common national and international IAQ standards in view of the scope to which they include direct or indirect evidence for the validity and applicability of their mandates and requirements. To this end, selected IAQ standards were assessed via a structured schema that includes not only basic information, quality indicators, and suggested and recommended value ranges, but also any reference to scientific studies. The findings of this effort identify certain issues with the transparency of the chain of evidence from the results of technical literature and standard-based IAQ recommendations. Moreover, recommendations are made for the development of future transparent and evidence-based IAQ standards and guidelines.

A research on occupant behaviour pattern of dwellings in the context of environmental comfort and energy saving
(Gazi Univ, Fac Engineering Architecture, 2016) Harputlugil, Gulsu Ulukavak; Harputlugil, Timuçin; Harputlugil, Timucin; 40295; 36110; Mimarlık
Occupants make a passive contribution to the building energy balance by their very presence; they also can have an active role through activities like opening windows, changing thermostat set points, tuning radiator switches or lighting switches, etc. Furthermore, in existing buildings, occupants also play a role in decisions regarding any interventions in the fabric and systems, especially where occupants own the building. In this paper, an evaluation of the survey results applied to occupants of dwellings in order to reveal effects of occupant behavior on energy consumption. The survey was applied to occupants of dwellings presented in four different climatic zones. There are two main issues aimed in the survey. Firstly, it is aimed to find out behavior patterns which are mostly effective on energy consumption. The other aim is to query the perception of occupants on comfort conditions and energy saving potential. The results of the survey showed that dominant occupant behavior which have an effect on energy consumption very significantly is opening/closing window. A major amount of occupant is aware of saving electricity; thus %92.9 of occupants prefer energy saving lamps for artificial lighting. Another essential result of survey is, in a general manner, sensitivity on energy consumption and satisfaction of comfort are increasing by education level increases.

Conceptual Framework for Developing Next Generation of Energy Performance Certificate (EPC) Systems
(2018) Harputlugil, Timuçin; 40295; Mimarlık
One of the main important tasks for sustainable development is to boost energy efficiency. Based on Energy Performance of Buildings Directive (EPBD) revealed in 2002 by European Union (EU) 40% of energy is consumed by buildings. In the same directive for energy efficiency a new model called Energy Performance Certification (EPC) is introduced and since then has been used by member and related countries. For a better sustainable development, this research aims to define conceptual framework to develop next generation of EPC with providing dynamic data gathering to monitor energy consumption of the buildings. Next generation EPC is designed to be a part of smart grid system and will be adapted as a plug-in. Considering the huge building stock in EU member and related states, new EPC will provide benefits not only for governing bodies but also energy companies (producers and suppliers) and users with real time dynamic data generation.
