Trombe Walls BRANZ FACTS SUSTAINABLE CONSTRUCTION #3 Trombe walls This factsheet promotes and provides the information needed to design, build and make proper use of a robust solar space-heating technology that can significantly enhance your home’s indoor comfort year round – Trombe walls. THE DEFINITION of a robust technology is the concrete wall.

In this work Trombe walls were studied for summer cooling of buildings. Ventilation rates resulting from natural cooling were predicted using the CFD (computational fluiddynamics) technique. The renoramlization group ( RNG) k-e turbulence model was used for the prediction of buoyant air flow and flow rate in enclosures with Trombe wall geometries. The CFD program was validated against experimental data fromthe literature and very good agreement between the prediction and measurement was achieved. The predicted ventilation rate increased with the wall temperature and heat gain. The effects of the distance between the wall and glazing, wall height, glazing type and wall insulation were also investigated. It was shown that in order to maximize the ventilation rate, the interior surface of a Trombe wall should be insulated for summer cooling. This would alsoprevent undesirable overheating of room air due to convection and radiation heat transfer from the wall. © 1998 Elsevier Science S.A.

This theoretical investigation tested a variety of building forms and found two general guidelines that govern performance. Across all building manipulations, results showed that forms minimizing volume and RODU T maximizing southern exposure perform best. This lines with rational thought; increased volume N increases the volume of required conditioned space, while maximizing southern exposure allows I for greatest winter solar gains and daylighting. Following this study, energy analysis was given for three, previously conceived housing designs – “Slope House”, “Underground House” and “X House”. In all cases, formal design (siting, building form, orientation) were given, fixed parameters. This proved a challenge to the energy optimization of the house. For the “Slope House”, building volume opens to the west without the benefit of southern expo- sure on the open face. Passive solar gains were minimal, with excessive shading on south facing windows. The majority of glazing is to the north, which effectively cuts the building’s thermal resistance/storage without the offsetting solar gains received on southern exposures.

  • Design, Optimisation and Construction of a Prototype for a Thermochromic Trombe Wall
    DESIGN, OPTIMISATION AND CONSTRUCTION OF A PROTOTYPE FOR A THERMOCHROMIC TROMBE WALL Fernando Martín-Consuegra, Carmen Alonso, Gloria Pérez, Borja Frutos, Ana Guerrero, Ignacio Oteiza (1) (1) Instituto Eduardo Torroja de ciencias de la construcción, CSIC. Madrid (SPAIN) Abstract Most of the existing buildings in Spain lack of any thermal insulation in their envelope. They are on urgent need to be refurbished to reduce their energy consumption to meet compliance with current European Directives. The standard solution for the rehabilitation of facades incorporate thermal insulation materials to reduce heat transmission. The work presented here proposes an extension of the conventional approach: the installation of Trombe walls on sunny facades incorporating an outer layer of thermochromic mortar in the external surface. The Thermochromic Trombe Wall (TTW) is a new system optimizing the traditional Trombe wall with addition of the thermochromic coatings (TCC). This improves the energy performance of existing buildings by enhancing their solar gains. This paper describes the design and configuration of the new TTW system. While traditional solutions can be evaluated with a simple heat transfer equation, a complex energy model is needed to evaluate TTW. An energy simulation technique is used to determine parameters that influence thermal performance. The thermochromic mortar transition temperature is designed in such a way as to achieve maximum efficiency. The results obtained from the parametric study were used to determine aspects for the construction of a first prototype on a laboratory test cell. The information obtained from the experiment will be used for the calibration of the energy model that will establish the potential for the incorporation of the TTW on existing buildings.

THERB for HAM, a dynamic thermal load calculation software, was used to estimate the heating ability of a double-layer Trombe wall for an office building. We designed a new double-layer Trombe wall that has two ventilated air cavities installed on the south facade of the office building, and a pipe with a temperature-controlled DC fan used to control thermo-circulation. The office building was located in Kitakyushu, Fukuoka, Japan. The temperature of the ventilated air cavity of the double-layer Trombe wall and the indoor temperature were simulated. It was more efficient for the DC fan to start when the ventilated air cavity temperature was 19 ◦C and the operative temperature of indoor was maintained at 20 ◦C. The results showed that the double-layer Trombe wall with a temperature-controlled DC fan can reduce yearly heating needs by nearly 0.6 kWh/m3 and improve the performance of a double-layer Trombe wall up to 5.6% (22.7% in November, 8.56% in December, 1.04% in January, 3.77% in February, and 3.89% in March), compared to the double-layer Trombe wall without an air supply.

  • Passive Solar Technique Using Trombe Wall - a Sustainable Approach
    IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) e-ISSN: 2278-1684, p-ISSN: 2320–334X Passive Solar Technique Using Trombe Wall - A Sustainable Approach Piyush Sharma1, Sakshi Gupta2 1(M.Tech. Scholar, Department of Civil Engineering, Amity University Haryana) 2(Assistant Professor, Department of Civil Engineering, Amity University Haryana) ABSTRACT: This work presents a detailed investigation on a Trombe wall, a solar wall, is an important element of passive solar design. It is a very thick wall and can be south-facing or north-facing depending upon the hemisphere, which is painted black and made of exclusive material that absorbs lot of heat. Trombe walls are enormous ‘passive’ ways of providing heat to an interior space. The main advantage of Trombe wall is that they are often easily built from locally available materials, very reliable and having less repair, maintenance and operation costs. These walls contribute in reducing heating and cooling costs of a building and hence these are considered as vital technique of sustainable architecture. Keywords - Solar Energy, Sustainability, Thermal mass, Thermal comfort, Trombe wall. I. INTRODUCTION Utilization of energy and its conservation has become prime concern due to ever increasing global warming effect. Energy can be very well conserved if utilized properly in buildings by application of various techniques. In high rise buildings, large amount of the energy is consumed for air conditioning and heating as well as for running a number of appliances of daily use. Energy consumed for heating in buildings has the largest proportion of consumption i.e. nearly 45% which needs to be continuously evaluated so as to reduce the energy utilization and make a sustainable environment [1].
