“…The table 1 shows some results of this research. Last researches in the façades field have been oriented towards dynamic solutions [5], façades that incorporate renewable energy [6] or strategies to reduce the building energy demand [7]. TE technology use has been limited to fields where high-tech technology is needed.…”

The research is looking for an innovative self-sufficient, industrialized and lightweight façade module that integrates a thermoelectric HVAC system. The principal aim of the research was to try providing a built answer to the current efficiency objectives (Directive 2010/31/CE), creating a façade solution that can be installed in new buildings or in already existing ones. This report tries to explain the theoretical design of this new façade system with Peltier cells.

“…Indeed, of the various energy efficient technologies considered by IEA-ECBCS Annex 44 activity [3], adaptive technologies embedded in the building envelopes are considered to have the largest potential to minimize the energy use in buildings. In particular, Double Skin Facades or Advanced Integrated Façades [5], switchable glazing [6], movable solar shading [7], wall integrated phase change materials [8], dynamic insulation [9] and multifunctional facades [10] are identified as the most promising adaptive façade systems and components in terms of energy reduction potential.…”

a b s t r a c tThe development of dynamic building envelope technologies, which adapt to changing outdoor and indoor environments, is considered a crucial step towards the achievement of the nearly Zero Energy Building target. It is currently not possible to evaluate the energy saving potential of innovative adaptive transparent building envelopes in an accurate manner. This creates difficulties in selecting between competing technologies and is a barrier to systematic development of these innovative technologies.The main aim of this work is to develop a method for devising optimal adaptive glazing properties and to evaluate the energy saving potential resulting from the adoption of such a technology. The method makes use of an inverse performance-oriented approach, to minimize the total primary energy use of a building. It is applied to multiple case studies (office reference room with 4 different cardinal orientations and in three different temperate climates) in order to evaluate and optimise the performance of adaptive glazing as it responds to changing boundary conditions on a monthly and daily basis. A frequency analysis on the set of optimised adaptive properties is subsequently performed to identify salient features of ideal adaptive glazing.The results show that high energy savings are achievable by adapting the transparent part of the building envelope alone, the largest component being the cooling energy demand. As expected, the energy savings are highly sensitive to: the time scale of the adaptive mechanisms; the capability of the façade to adapt to the outdoor climatic condition; the difference between outdoor climatic condition and the comfort range. Moreover important features of the optimal thermo-optical properties are identified. Of these, one of the most important findings is that a unique optimised technology, varying its thermo-optical properties between a limited number of states could be effective in different climates and orientations.

“…In contrast to other studies (e.g. [15]) this contribution evaluates the efficiency of façades using a multi-criteria approach combining energy performance and various environmental impacts. The results show that all 10 façade assemblies with TIMs have lower overall environmental impacts compared to a reference assembly with ETICS.…”

Contemporary architects and the construction industry are trying to cope with increasing requirements concerning energy efficiency and environmental impact. One of the available options is the active utilization of energy gains from the environment, specifically solar energy gains. These gains can be utilized by, for example, solar walls and facades. The solar façade concept has been under development for more than a century. However, it hasn’t achieved widespread use for various reasons. Rather recently the concept was enhanced by the application of transparent insulation materials that have the potential to increase the efficiency of such façades. The presented study evaluates the environmental efficiency of 10 solar façade assemblies in the mild climate of the Czech Republic, Central Europe. The evaluated façade assemblies combine the principles of a solar wall with transparent insulation based on honeycomb and polycarbonate panels. The study applies Life-Cycle Assessment methodology to the calculation of environmental impacts related to the life cycle of the evaluated assemblies. The results indicate that even though there are several limiting factors, façade assemblies with transparent insulation have lower environmental impacts compared to a reference assembly with standard thermal insulation. The highest achieved difference is approx. 84% (in favour of the assembly with transparent insulation) during a modelled 50-year façade assembly service life.
