Embodied Energy of Stabilized Rammed Earth

The paper references a number of sources to create a compact account of the intrinsic energy, physical parameters and subsequent thermal potential of rammed earth that has been stabilized with Portland cement. The aim of this article is to show that a lower embodied energy does not necessarily reduce thermal comfort if careful consideration is given to design.

Thermal Responses of Stabilized Rammed Earth for Colder Climatic Regions

The paper focuses on thermal properties for laboratory simulation testing to ascertain the viability of low-cement, Stabilized Rammed Earth (CSRE) as an ecological and sustainable envelope structure for colder regions. The results will be used to create a point of reference for the thermal performance of vernacular CSRE architecture, which could be integrated into building law, norms or standards by interested institutions.

Dynamic Thermal Properties of Uninsulated Rammed Earth Building Envelopes

The paper demonstrates the thermal admittance procedure as a technique to quantify the dynamic thermal properties of two uninsulated rammed earth building components subjected to radiative and conductive heat transfer processes. With the aid of Australian climate data and a climate chamber, this research paper uses a dynamic thermal property calculator developed by Arup in accordance with EN ISO 13786:2007 to quantify the performance of a homogenous rammed earth envelope subjected to in-situ measurements that mimic real conditions.

Analysis of an Indoor Environment in Year-Round Operation

Implementation of energy efficient buildings is one way to meet the requirements of the European Parliament, which has adopted the agreement 20/20/20. Given the low percentage of the amount of energy efficient buildings in the climatic conditions of the Slovak Republic is a little knowledge of their real operation. The paper describes the experimental measurement of the physical quantities in energy-efficient building is selected in the climatic conditions of the SR in the introduction of the contribution is a description of an experimental building, in which the measurement was done, the description and the deployment of measuring instruments. The conclusion of this paper is devoted to processing and statistical analysis of measured physical quantities. The analysis results show that the internal state of residential houses is largely influenced by home users.

Solution of Own Window Pane Oscillation by Subspace Iteration Method

Solving building acoustic of structures leads to a requirement to know behavior of dynamically loaded structures. Often used design is a window, that glass pane can be modeled as board. When measuring acoustic qualities of windows, monitored value is frequency of excited sound as a sound pressure. From solutions of dynamically loaded structures is known fact that when excited frequency of load is equal, or approximately equal to its natural frequency, there is an unwanted resonance phenomenon.

Preparation Measurements and Assessment of Roof Systems

Abstract The Institute of Architectural Engineering at the Civil Engineering Faculty TU of Kosice, in its ongoing research, aims to monitor the physical properties of building envelope structures with emphasis placed on hydrothermal problems, at present. The research focuses on the assembly of equipment in climate chambers with their respective sample envelopes and fenestration systems, which are involved in a measuring experiment. The prime aim is to design a logical and transparent system for gathering, evaluating and storing hydrothermal related data. This contribution further illustrates the embedding system of measurement points in installed samples and the system of monitoring their physical properties over an annual period.

Analysis of Energy Balance in Elementary School Building

One option to meet the requirements of Europe 2020 is construction of energy efficiency buildings. These buildings are low heat energy demand, which is influenced by various factors. The article describes the impact of different operating modes on the heat demand for heating in the building of the pavilion elementary school. The impact was assessed in simulation calculation program. The aim was to obtain knowledge about the behavior of the building in terms of thermal comfort in different operating modes during the heating season. The knowledge gained will enable more effective operation of HVAC systems. Increased efficiency of operation allows energy savings.
