Energy performance assessment of an advanced responsive multifunctional facade module: first results of an experimental campaign

Responsive Building Elements (RBEs) are technologies for the exploiting at the building scale renewable energy sources and the opportunities offered by the environment. Among the RBE concepts identified by the IEA-ECBCS Annex 44, Advanced Integrated Façades (AIFs) is probably one of the most promising technologies. Important players in the field of the façade have started to develop integrated modular façade systems (Multifunctional Façade Modules - MFMs), with a dynamic behaviour and interacting with the other building services, in order to reduce the building energy consumption and maximize the indoor comfort conditions. In the frame of a research activity aimed at…

Zero Emission Building Concepts in Office Buildings in Norway

Zero emission buildings (ZEB) are buildings with a minimized energy consumption and renewable energy supply with zero greenhouse gas emissions. There is no common accepted definition of zero emission buildings. This is due to issues in defining the boundary of a balance in terms of building site and time frame of this balance. Further, there is no standard on accounting for emissions (on material, components, system, and building level) nor is there a standard for emissions from other building related environments. In this paper the goals for ZEB are specified and implications for components are discussed.

On the integration of wood stoves for the space-heating of passive houses: Assessment using dynamic simulation

Publication Year:
2012
State-of-the-art wood stoves could be an attractive solution for the space heating of passive houses. The question of the integration of wood stoves in passive envelopes is rather new and still open, the main constraints being the power oversizing ant the heat distribution. The paper proposes a low-resolution simulation approach to provide an insight into the whole-year thermal comfort using a stove, and into the relative effect of the large number of physical parameters involved in the problem. In particular, a simple stove model is developed for detailed dynamic simulations in order to fairly represent the heat emission properties of…

Monodisperse hollow silica nanospheres have been prepared by using a polystyrene nanosphere template-assistant approach and their potential as antireflection (AR) coatings for window applications has been discussed. The as-prepared hollow silica nanospheres have a typical inner diameter of 200 nm and a shell thickness of 15–20 nm. The AR effect over the ultraviolet-visible-near infrared spectral region has been observed for the hollow silica nanospheres, with a minimized reflection of about 5.2 % at 500 nm, compared to 8.5 % of a plain float glass substrate. By modifying the structural features of the hollow silica nanospheres, their AR properties can be…

Characterization of the optical properties of a PCM glazing system

Authors:
Publication Year:
2012
The optical characteristics of an advanced glazing system are presented in this paper. The investigated glazing system is based on the incorporation of a paraffin-based Phase Change Material (PCM) into a transparent component, made of two extra-clear glass panes and a cavity where the PCM layer is placed. Due to the highly scattering property of the system (when the PCM is in solid state), the use of a large integrating sphere equipment (75 cm diameter) is necessary to obtain reliable results. The spectral transmission, reflection and absorption coefficients of the PCM glazing system are measured between 400 and 2000 nanometers,…

Thermo-physical behaviour and energy performance assessment of PCM glazing system configurations: A numerical analysis
Authors:

Publication Year:

The adoption of Phase Change Materials (PCMs) in glazing systems was proposed to increase the heat capacity of the fenestration, being some PCMs partially transparent to visible radiation. The aim of the PCM glazing concept was to let (part) of the visible spectrum of the solar radiation enter the indoor environment, providing daylighting, while absorbing (the largest part of) the infrared radiation. In this paper, the influence of the PCM glazing configuration is investigated by means of numerical simulations carried out with a validated numerical model. Various triple glazing configurations, where one of the two cavities is filled with a…

Influence of user-behavior on the performance of the building and the energy supply system

It is becoming conventional approach to evaluate the building envelop losses using detailed dynamic tools such as EnergyPlus, ESP-r and TRNSYS. However, the user-related loads (and their variations) in the building are usually oversimplified during performance evaluation of those buildings and associated HV AC systems. This paper presents a methodology to evaluate the performance of buildings and their energy supply systems while taking into account the user-related loads (non-HV AC & DHW) at individual household levels. For this purpose, a single family house (two different insulation cases) built in Oslo climate using an alternate duty air to water heat pump…

2012
Transparent façades are often used to increase the aesthetic value of the building and to provide visual contact with the outdoor. However, together with several positive features, it should be mentioned that glass façades may reduce the quality of the indoor thermal environment, causing thermal discomfort especially due to overheating in the summer season. The aim of this paper is to compare the implications on thermal comfort of different glazed façades, whose surface temperatures have been monitored during several experimental campaigns. The analyzed glazing systems were double skin façades and non conventional single skin façades integrating different materials (i.e. phase…
