An investigation into the age-based thermal energy balance of occupied classrooms in primary schools

Taner, Özün
The effect of indoor heat gain from occupants as a bio-thermal source was hypothetically assessed in terms of its contribution to overall heating requirements during such occupancy and hence to potential energy savings. The spaces considered were classrooms in a sample of 6 public co-educational primary schools located within the city limits of Ankara built after 1998, the date when compulsory primary education was integrated to encompass grades 1 through 8 for ages 6 to 14, respectively. Being so, this allowed distinguishing disparities among age groups on the basis of classroom density and body surface area. Data for both were obtained from existing sources. As norms for the latter essentially pertained to adult populations, pertinent corrections were made for each of the age groups in question as well as for gender. Additional adjustments were made on the basis of the literature in order to integrate data on local weather conditions into heat balance equations. Energy requirements for heating were calculated according current Turkish standards. Results based on extensive comparisons using Student’s t-test confirmed that there were significant differences between grades in terms of supplementary heating requirements. These differences were not, however, large enough to warrant any meaningful intervention with regard to such design aspects as window orientation, exterior wall composition and/or indoor temperature level.


Appropriate passive cooling strategies for hot and humid climates : a case study in cyprus
Hançerli, Mustafa Yılmaz; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2008)
In this study, energy conservation potential of appropriate passive cooling and basic heat avoidance strategies were investigated for hot and humid climates. Within this framework, thermal behavior of a case study building that is situated in Cyprus was assessed by collecting temperature and relative humidity data from various rooms of the building during certain days in August. Then, by using feasible simulation strategies of the software tool Summer-Building, the effectiveness of passive cooling measures ...
The effect of sun spaces on temperature patterns within buildings: two case studies on the METU campus
Kırmızı, Hacer; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2009)
The aim of this study was to investigate the passive and active parameters affecting energy efficiency of two office buildings with sun spaces, namely the MATPUM Building and the Solar Building on the Middle East Technical University (METU) Campus, Ankara and the effect of sun spaces on temperature patterns within mentioned buildings. Both buildings were oriented in the same direction, namely south. However, the location and the type of the sunspaces differed from each other. The sun space in the MATPUM Bui...
Investigation of the effect of outdoor temperature data on the building heating energy requirement and validity of the TS 825 degree-day region clustering
Altun, Murat; Akçamete Güngör, Aslı; Akgül, Çağla (2020-01-01)
The outdoor temperature is one of the most important parameters affecting the calculation of energy requirements of buildings. Determination of the thermal insulation details and heating energy requirement of the buildings in Turkey, where energy consumption is dominated by space heating, is made according to TS 825 "Thermal Insulation Rules in Buildings" standard. In TS 825, the provinces are clustered in degree-day regions (DDR) according to their climatic conditions. The main climatic parameter that sepa...
Theoretical investigation of a humidification-dehumidification desalination system configured by a double-pass flat plate solar air heater
Yamali, Cemil; Solmus, Ismail (Elsevier BV, 2007-02-05)
The aim of this study is to investigate theoretically the effect of different system operating conditions, types of air heater, and some different design parameters and a weather condition on a solar water desalination system performance under the climatological conditions of Ankara (40 degrees N,33 degrees E), Turkey. For this purpose, a computer simulation program based on the mathematical model is developed by means of MATLAB software. In this simulation program, the fourth order Runge-Kutta method is us...
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...
