“…For an exterior reflective surface coating in a cold climate, the energy usage ended up being larger than for a similar uncoated building. In warm climates the results were reversed, exterior reflective surface coating gave energy savings, while interior reflective surface coating gave an increase in energy usage (Joudi et al [41]). Other studies also highlight the effects of coatings between different climate regions (Guo et al [22]).…”

Low-emissivity (low-e) materials can be used in order to reduce energy usage in both opaque and transparent areas of a building. The main focus for low-e materials is to reduce the heat transfer through thermal radiation. Furthermore, low-e materials will also influence on the daylight and total solar radiation energy throughput in windows, the latter one often characterized as the solar heat gain coefficient (SHGC). This work reviews low-e materials and products found on the market, and their possible implementations and benefits when used in buildings. The SHGC is often left out by many countries in energy labellings of windows. With opaque materials, research is still ongoing to correctly calculate the effect with regard to thermal performance when applied in buildings. Future research perspectives on where low-e technologies may develop are explored. To the authors' knowledge, there seems to be little available literature on how ageing affects low-e materials and products. As this is of large significance when calculating energy usage over the lifetime of a building, ageing effects of low-e materials should be addressed by manufacturers and the scientific community.

“…Moreover, in the last years, the research in the building energy saving field as led to the investigation of new building integrated technologies and innovative heating, ventilating and air conditioning (HVAC) systems often supported by renewable energies or innovative control strategies [33]. Thus, in order to analyze the energy performance of innovative building plant systems and to predict the whole building thermodynamic behavior, more and more suitable detailed mathematical algorithms/models for computer-based simulation and optimization analyses are being developed and used [11,22,24,34]. In general, in detailed building models, the energy response of each thermal zone is suitably analyzed by taking into account almost all the physical phenomena.…”

Abstract:In this paper details about the results of a code-to-code validation procedure of an in-house developed building simulation model, called DETECt, are reported. The tool was developed for research purposes in order to carry out dynamic building energy performance and parametric analyses by taking into account new building envelope integrated technologies, novel construction materials and innovative energy saving strategies. The reliability and accuracy of DETECt was appropriately tested by means of the standard BESTEST validation procedure. In the paper, details of this validation process are accurately described. A good agreement between the obtained results and all the reference data of the BESTEST qualification cases is achieved. In particular, the obtained results vs. standard BESTEST output are always within the provided ranges of confidence. In addition, several test cases output obtained by DETECt (e.g., dynamic profiles of indoor air and building surfaces temperature and heat fluxes and spatial trends of temperature across walls) are provided.

“…To investigate the flux of thermal radiation from the ceiling to the ice in indoor ice rinks with both low and high emissive interior roofs surfaces, the simulation environments IDA SE and IDA ICE 4.0 are used to solve a system of non-linear equations simultaneously, based on the work presented in [4]. In this model both interior and exterior surface temperatures, as well as discrete cell temperatures through the roof panel are simultaneously solved and coupled in an hourly dynamic simulation with varying outdoor conditions (i.e.…”

“…In a previous work by Joudi et al [4] introduces a model for calculating the effect of both interior and exterior optical properties of a horizontal roof sandwich panel in terms of net energy flux per unit area. Sandwich panels usually consist of two coil coated steel sheet profiles, which are tightly pressed and glued to an insulation core.…”

Abstract:The aim of the study is to develop a model for the energy balance of buildings that includes the effect from the radiation properties of interior and exterior surfaces of the building envelope. As a first step we have used ice arenas as case study objects to investigate the importance of interior low emissivity surfaces. Measurements have been done in two ice arenas in the north part of Sweden, one with lower and one with higher ceiling emissivity. The results show that the low emissivity ceiling gives a much lower radiation temperature interacting with the ice under similar conditions. The dynamic modelling of the roof in ice arenas shows a similar dependence of the roof-to-ice heat flux and the ceiling emissivity. A second part of the study focus on how to realise paints with very low thermal emissivity to be used on interior building surfaces.
