Application of TS 825 Turkish thermal insulation standard using BIM

Thermal insulation offers an efficient passive solution to provide energy savings in the buildings. In Turkey, TS825 “Thermal Insulation Requirements for Buildings” standard regulates the thermal performance of the buildings.In current practice, the energy requirement of a building is calculated manually according to geometric data andthermal properties of the elements on the building envelope. Geometric data is extracted from 2D drawings,whereas materials forming the layers of the exterior building elements need to be matched with the materialdatabase given in the standard in order to determine their thermal properties for calculating thermal conductivityof those elements. Therefore, obtaining both geometric and thermal data for all building elements on the envelopeis quite repetitive and a time-consuming process. In this study, we developed an application for model based TS825 analysis. The application is encoded in Revit Add-in Dynamo environment and composed of three modules:(i) inspection module to extract all required data from a Building Information Model for checking the availabilityof the data and updating the missing ones; (ii) analysis module to automate TS 825 heating energy requirementcalculations according to the extracted data; and (iii) control module to analyze the fitness of insulation design ofthe building to regulations of the thermal insulation standard. In this paper, the challenges encountered during theconstruction of the application are also explained in detail. The application was tested with a residential case studybuilding and its result was compared with the manual calculations for accuracy analysis. The case analysisindicates that the application is able to generate consistent model based TS 825 analysis with the manuallyperformed analysis given the building model is constructed accurately and according to the calculationrequirements of the application and the TS 825 standard.

Çakmaklı, Ayşem Berrin; Elias Özkan, Soofia Tahira; Pedergnana, Matthieu; Farzin Moghaddam, Maryam; Deljavan, Nastaran; Aslan, Ece(2014-12-31)
This project proposal builds on previous research by the project team to demonstrate how energy efficiency in buildings can be significantly increased all year round by combining passive solar heating, appropriate building materials, and adequate insulation with efficient heating techniques such as the rocket stove. Design and production of solar units and energy efficient rocket stoves will be followed by monitoring of the thermal performance and energy consumption of selected spaces. Results will indicat...
Development of silica fume-based geopolymer foams
Shakouri, Sahra; Bayer, Özgür; Erdoğan, Sinan Turhan (Elsevier BV, 2020-11-01)
Thermal insulation materials are critical for reducing the energy consumption and carbon emissions associated with buildings. A good insulation material must not only have low density and sufficient mechanical properties but also resist high temperatures and fires. In addition, its production process must be simple and inexpensive. This study describes the production of very low density (>85 kg/m(3)) inorganic foams with high porosity (<94%). Silica fume and NaOH solutions are mixed to prepare a geopolymer ...
Performance assessment of lime-pozzolan mortars with straw aggregate for sound and thermal insulation purposes
Kaplan, Miyase Merve; Ay, Bekir Özer; Department of Building Science in Architecture (2019)
The main concern of the study is to propose lime-based straw-mixed mortars with pozzolanic additives to be used as qualified building materials,particularly for sound and thermal insulation purposes and to assess theirperformance properties in this regard. Compositional properties of a specific type of traditional exterior plaster wereinspiring for the production of porous lime-based straw-mixed mortar samples with high thermal resistivity and sound absorption properties. Se...
Proposal of a Novel Gravity-Fed, Particle-Filled Solar Receiver
JOHNSON, Evan; Baker, Derek Keıth; Tarı, İlker (2016-10-14)
Solar Thermal Electricity power plants utilizing solid particles as heat transfer and storage media have been proposed by several research groups, with studies citing benefits of increased thermal efficiency and lower cost. Several types of solid particle receivers have been proposed, with leading designs consisting of particles falling or suspended in air. A new solid particle receiver is proposed here, consisting of a receiver fully packed with particles flowing downward with gravity. Particle flow rate i...
Evaluation of a Tunnel Form Social Housing Unit Based on Passive Design Principles
Yılmaz, Deniz Derya; Tanyer, Ali Murat (null; 2015-05-28)
Many countries developed methods for the definition of houses with a very low energy use in the past years, among which Passive House represents a dwelling with extremely thermal insulated external envelope, good air tightness and highly efficient ventilation heat recovery to reduce energy consumption of buildings greatly depending on the location. This paper is carried out to see if it is possible to design tunnel-form structures as Passive House buildings. Also in this paper, construction of a Passive Hou...
