Energy saving in the conventional design of a Spanish house using thermal simulation

During the last decade, regulations designed to change the way of designing, building, maintaining, renovating and demolishing buildings and their surroundings have been developed at European level. However, sustainability targets shift throughout the life of a building and design solutions should go beyond strict compliance with each country's regulations. This study prioritises a building's energy behaviour during its use. It demonstrates the value of combining simple passive strategies with thermal simulation tools in standard architectural design practice. To achieve this, we started from the conventional design of a house in the North of Spain, applying passive techniques to achieve energy savings and environmental improvements that exceed regulatory requirements. Simple heating and cooling practices are incorporated into the design. The final house combines all favourable actions that manage to reduce consumption, especially during the most intense winter period. The final design is fully south facing, with an additional 20% glazing in the north and south façades, a 35-cm lintel in the window frames and an additional 2 cm insulation on the façade. Simulation reduced overall thermal consumption by almost 13%. The embodied energy used for the improvements is barely significant. Although the additional investment is arguably not profitable in economic terms, the increased investment is minimal in comparison with total investment in the building.

Effect of thermal mass on the thermal performance of various Australian residential constructions systems

The impact of thermal mass on the thermal performance of several types of Australian residential construction, namely: cavity brick (CB), brick veneer (BV), reverse brick veneer (RBV), and light weight (LW) constructions, was examined numerically using the commercial AccuRate energy rating tool developed by the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO). The performance of each construction type was evaluated using four different hypothetical building envelopes, referred to here as building modules. It was found that the thermal mass had a dramatic impact on the thermal behaviour of the modules studied, particularly in those where the thermal mass was within a protective envelope of insulation. The RBV and CB constructions were found to be the most effective walling systems in this regard.

Energy efficient surfaces on building sandwich panels—A dynamic simulation model

The choice of building envelope is critical for the energy performance of buildings. The major part of the energy used by a building during its lifetime is used for maintaining a suitable interior thermal climate under varying exterior conditions. Although exterior heat radiation properties (i.e. total solar reflectivity and long wave thermal emissivity) have been well accepted to have a large impact on the need for active cooling in warmer climate, the effect of a reduced thermal emissivity on interior surfaces on the building thermal energy flux is rarely studied. This paper addresses the sensitivity of the thermal energy flux through a sandwich panel, by systematically varying the surface thermal emissivity (both interior and exterior) and total solar reflectance of exterior surface, for three geographical locations: southern, middle and northern Europe. A model is introduced for calculating the effect of both interior and exterior optical properties of a horizontal roof panel in terms of net energy flux per unit area. The results indicate potential energy saving by the smart choice of optical properties of interior and exterior surfaces.
