Sustainable Building

Introduction

Heating, cooling and ventilation are required systems in order to make a building comfortably habitable for the occupants. In ancient times these facilities are provided by means of natural ways. The earth provides abundant free energy in different forms. It is possible to take the advantage of natural sources via some strategies which requires no energy. However with the improvements in the technology, mechanic systems are pretend to be common. These systems are required energy in order to be maintained. Domestic energy consumption has a big share of total energy demand of the humanity.

The significance of the domestic energy requirement is realized during an energy crisis called 'Peak Oil' (Roaf, 2013). This economy based problem also lead to an improvement on environmental awareness. Moreover, some studies revealed that mechanical systems in buildings stimulate the some health problems such as sick building syndrome which decrease the occupant comfort (Bansal at all., 1994). The passive design strategies also provide a healthier ambient. The building should be shaped and oriented according to the requirement of these strategies (Bansal at all., 1994). Micro and macro climate of the site should have taken into consideration during the design stage in order to create an efficient system in the building.

 

The Purpose of the Research

This research is to assess the passive heating, cooling and ventilating methods and to find out the share of the strategies on the energy that is saved by these strategies in Istanbul, Turkey. It is aimed to determine which passive strategies are efficient and which building fabrics are superior to the others in order to achieve the passivhaus standards. It is also aimed to create a template for design and construction stage for housing that consumes energy within the limits of the passivhaus standards in Istanbul. The main concern of this study is to answer the question of is it possible to achieve passivhaus standards by means of just passive systems in Istanbul.

Research Methodology

Firstly, a detailed literature review on passive design strategies and passivhaus standards, climatic conditions in the city will be conducted. Then a common housing plan type in the city will be selected randomly. The building will be modeled on 3d modeling program; Google sketch up. Then the model will be tested via the software of Integrated Environmental Solutions (IES) which is a simulation program to test energy demand and carbon emission of a building. A base model will be used as a reference point. Then other models with some passive strategies will be simulated. The findings of each scenario will be compared with the results of base model. The findings will be presented as graphics.

Literature Review

The passivhaus is a German standardization to energy efficient buildings. It is originally developed for domestic buildings; however, the standards are also adopted for the other building types (Sassi, 2006). A reduction on energy demand within the limits of occupant comfort is ...
