This is the internet realization of SEMPER, an active, multi-domain, space-based, object oriented design environment for integrated building performance modeling. The key features of the S2 environment are as follows: A user can access the system regardless of the computer hardware, operating system or the location on a network; geographically distributed users can asynchronously generate a building model through the user interface; this building model can then be simultaneously evaluated with multiple simulation applications running on remote simulation servers; persistent storage is provided for project data and evaluation results; designers using the system have access to multiple libraries that contain building information such as material data, construction types, schedules, and weather data.

A new model for representing building codes in computable form is developed for use in building automated compliance checking systems. The model adopts Nyman and Fenves’s four-level representation paradigm as a theoretical base and uses the semantic modeling approach of the SMARTcodes project for developing the building code representation. This hybrid model breaks down the representation into four levels which allows separate modeling of domain concepts, individual rule statements, relationships between rules, and the overall organization of the building code. The applicability of the model has been evaluated with a case study. The İzmir Municipality Housing and Zoning Code has been chosen as a document that represents a complex code document that is in effect throughout Turkey. The formalizable rules in this code have been modeled based on the new representati...

Especially, the integration of BIM with GIS is crucial for areas, which need detailed information on buildings and their surroundings. Automated code compliance checking against zoning codes is an area that requires both zoning data and building design data. In an ideal automated zoning code checking process, building codes should be retrieved from the responsible authority, data regarding the neighborhood the project is located in should be retrieved directly from the local municipality’s GIS, and the building project should be supplied by the designer as a BIM file. The checking process should be able to work with a combination of GIS and BIM data and generate a compliance report. Although recent BIM-GIS integration efforts have been successful in some areas, BIM-GIS integration studies in the context of automated...

However, after thirty years of research, interoperability of performance analysis tools with CAAD environments is still far from being seamless. Yet, all commercial CAAD vendors have recently started offering an array of building analysis tools. It is fair to expect a new surge of efforts in integrating prediction and evaluation capabilities within CAAD systems over the next few years. Building on lessons learned, this paper argues the need for a unification infrastructure for building performance and outlines the requirements for building an analysis network.

A seamless design and evaluation environment has been envisioned by researchers since the early days of computational design but the integrated design system has been elusive for the last 30 years. With the recent focus on environmental sustainability, topics in building performance are gaining importance at many educational institutions. However, the lack of a proper computational environment for integrated design is a major hurdle for both students and professionals. This paper will summarize the history of integrated design research and thus hopes to help educators plan for multidisciplinary coursework.

Ideally, digitally modelled building codes and urban data should be retrieved from municipalities, and the digital building model should be checked automatically based on the collected information. However, BIM tools do not contain and do not allow managing geographical information at a neighborhood scale. Current GIS applications also do not store all of the information required by building codes. Even if they did, interoperability between GIS and BIM environments are problematic. This paper describes the development of a zoning domain model for automated compliance checking of building projects. The proposed model is illustrated through a proof-of-concept GIS application, where geometric and semantic data are stored, queried and exported as a GML file. Use of this data model for automated code checking is an example for how GIS data can seamlessly complement BIM data making expansion of BIM schemas unnecessary.

Tracking of occupant movements provides objective data facilitating the development of new metrics for evaluating spatial layouts. This paper starts by outlining an overall methodology for Spatial Layout Evaluation based on occupant movements. Then, a platform for acquisition and interpretation of objective data to better understand how space is utilized by occupants is introduced. This platform is the Trajectory Data Processing Framework (TDPF). It supports investigating correlations between occupant movements and problems associated with spatial layouts. Finally, as a proof-of-concept implementation of this framework, a set of tools for analysis of occupant interaction with layouts, called Occupant Layout Interaction Analysis (OLIA), is presented.

Building codes are complex, and the development of computer implementable representations is challenging. As a case in point, this paper reports on experiences gained while modeling ̄zmir Municipality Housing and Zoning Code (IMHZcode). First, IMHZcode was analysed to understand the various types of information contained in it in order to develop a comprehensive building code model. The rules were classified according to their formalizability and self-containedness. Then, existing modeling approaches were evaluated to find the most convenient method that meets the needs for modeling IMHZcode. A key criterion used in this evaluation was ease of maintenance by non-programmers. The paper concludes with an illustrative example of the selected methodology's application within the context of IMHZcode

For evaluating acoustics in these spaces, researchers predominantly investigate sound pressure levels and reverberation times. Yet, noise in eating spaces originate from a wide variety of sources and is hard to describe and evaluate with only sound pressure levels and reverberation times. Better metrics for acoustics in closed public spaces are needed. Psychoacoustic parameters of loudness, sharpness, fluctuation strength and roughness are promising metrics that have been used by many recent studies evaluating noise annoyance. However, unlike the established metrics such as reverberation time, no set of recommended values exist for these parameters, yet. The aim of this study is to investigate noise in eating establishments through psychoacoustic parameters and understand both the noise characteristics and the metrics themselves. This paper presents a set of sound recordings during lunch hours in ...

Naturally, all businesses aim to provide as much as possible for their customers. They analyze and try to meet all their needs. Designs for commercial spaces are especially well thought out. Marketing professionals are keen on observing consumer behavior and laying out design principles to increase spending. Background music is one aspect of commercial spaces such as department stores, supermarkets and shopping centers that has been studied for such purposes. The general acceptance that music is pleasing and everyone would like some music to accompany them, has led businesses to focus on choosing the right type of music and determining optimum sound levels without considering an option where music is absent. Over the last half century, first, the boom in the recording industry and later, the digital revolution has made powerful equipment affordable and music itself accessible. As a result, background music has become almost ubiquitous in the public realm. However, more and more, music is being perceived as disturbing noise. The high levels of sound or the inappropriate choice of music, or both, are seen as the cause of most disturbances. Yet, the use of background music itself is not being questioned. As no community has a common music taste, in public spaces we need to share, elimination of background music should be given more consideration. This paper presents a summary of the literature focusing on background music in commercial settings and reports preliminary results from a questionnaire study for customer preferences with regard to background music in public spaces-cafes and restaurants in particular. The survey dwells on perceptions, expectations and preferences of customers in spaces with and without background music in order to determine if spaces without music are preferred over spaces with music.

Implementation of BIM, however, requires comprehensive research and strategic planning. Industry-wide and organizational implementation guidelines and standards have been published around the world either to encourage organizations to adopt BIM or to present the minimum requirements to be followed where BIM implementation is a statutory obligation. In contrast, governments or organizations in several countries such as Turkey have not mandated BIM implementation and provide no guidance. Organizations in these countries which plan to adopt BIM processes are forced to develop their own implementation plans. The purpose of this study is to provide guidance in BIM implementation for construction companies in countries where BIM implementation has not been mandated particularly during the constructi...

Organizations are forced to restructure their practices. The role of the architect within the new multi-disciplinary design team will depend on the architects’ skills in communicating with other team members. Architecture schools need to prepare students for this change. Collaborative aspect of design should be incorporated into the curriculum. This paper reports on the collaboration initiative between the architecture and civil engineering departments at Balıkesir University. The initiative is investigating the extent to which courses can be coordinated across departments. Students from three different courses have been asked to provide analysis and feedback for the same project concurrently. The results confirm that BIM technology can effectively support collaboration even among undergraduate students who are relatively inexperienced with interdisciplinary data exchange.

They have also started to be used for evaluating soundscapes of open areas and enclosed spaces. This research aims to find out the relationship between the psychoacoustic parameters and acoustic comfort in non-acoustic enclosed public spaces, specifically in eating establishments. Both on-site measurements and laboratory listening tests were conducted for five eating establishments. During on-site measurements, a simultaneous questionnaire study was also carried out. Subjective and objective data were comparatively evaluated. Listening tests were based on auralizations with calibrated simulation models. This provided a research model, that allows control over the acoustic environment without having to make real changes in the physical elements of the eating establishments. The auralization sound files were presented to listening test participants with headphones and they evaluated soundscapes with different psychoacoustic properties. As results, better acoustic comfort was found to be related with higher sharpness, lower reverberation time, lower loudness and lower roughness values for the examined parameter ranges.
