This paper develops previous research on passive house (PH) space heating. A simple and accurate ground heat exchanger model is developed. It is based on a numerical transient bi-dimensional approach that allows to computing the ground temperature at the surface and at various depths. The new...

This paper develops previous research on space heating in passive houses (PH). The results reported are based on a complex theoretical model used to simulate the heating system operation in Pirmasens PH (Rhineland Palatinate, Germany). The economic feasibility of different active space heating...

Integrated control by controlling both natural ventilation and HVAC systems based on human thermal comfort requirement can result in significant energy savings. The concept of this paper differs from conventional methods of energy saving in HVAC systems by integrating the control of both these...

A dynamic simulation model for heat and water vapor transfer in a naturally ventilated, fog-cooled greenhouse was developed to predict the temperatures of air, plant, cover and floor surface and the relative humidity in the greenhouse. Transpiration and evaporation were also predicted. An...

The main aim of the study is to investigate passive cooling performance in traditional urban contexts in the hot humid climate of the city of Dubai. Three cases were simulated for Al-Ras area with laminar and turbulent wind flow depending on Computational Fluid Dynamics (CFD) methodology. The...

The objective of this paper is to study the benefits of application of solar chimney on the south roof and cool metal ceiling on the north roof through the experiment in a detached building called a controlled cell, and the related numerical model constructed from a computational fluid dynamics...

This paper presents investigation on the use of solar chimney (SC) in high-rise building. To this end, two small scale models of a three storey building were built. The floor dimensions of each storey are 1.2×2×1m. Solar chimneys were integrated into the south-faced walls of one unit whereas...

The paper discusses the possibility of offering thermal comfort, without inducing mechanical energy cost, in new habitations, built in European style and situated in a hot and humid climate, by means of a construction element: the Roof Solar Collector (RSC), which is made by using concrete...

Eight recent projects of A. N. Tombazis and Associates are described. These buildings, five office buildings, a museum, a hospital and an exhibition centre, incorporate various bioclimatic design aspects which are incorporated for increased comfort, lower energy consumption and environmental...

Experimental wind tunnel and smoke visualization testing as well as CFD and analytical modeling were conducted to investigate the performance of a two-sided wind catcher. This type of wind catcher is divided internally into two halves for the purposes of air supply and extract. In this study,...
