KELVIN - Reducing the urban heat island effect via improving the reflective properties of buildings and urban areas
The aim of this project was to estimate the potential to reduce urban heat islands via low-tech measures such as the variation of the surface albedo, using the City of Vienna as an example. The project has also assessed the energy savings and greenhouse gas emission reductions due to the decreased energy demand for cooling as a result of such measures.
In the course of the project FFF-TaliSys novel daylighting systems based on freeform surface technology are developed and implemented into functional models, thus, innovative systems that solve the contradictory requirements of daylighting systems. The aim is to develop systems for façades and skylights that yield optimal visual and thermal functionality, but work without moveable parts and complex controls.). For the integration into the building skin as well as the optimization of the optical systems both thermal and visual boundary conditions are taken into account. Thereby, energy-efficient solutions shall result, which guarantee highest visual and thermal comfort in new and retrofitted buildings.
Multfunctional facades with integrated artificial- and daylighting systems had been simulated and evaluated regarding lighting and energy (lighting quality and energy demand). The results create basics for further façade developments and for academic education.
Syn[En]ergy: Development of Potential Synergy Effects between the Interdependency of Urban Planning goals and Photovoltaic Usage on Open Urban Landscapes
Open spaces such as parking lots, brownfields and some categories of recreation areas offer an underutilised potential for photovoltaics in urban regions. In the course of Syn[En]ergy an inter- and transdisciplinary approach potential synergies and conflicts with other use demands were investigated, a typology and practical solutions for selected areas with regard to requirements from economy, urban planning and design, legal as well social aspects developed, and then evaluated by stakeholders from enterprises, administration and the general public.
The aim of this project was to advance the state of the art in the engineering of double-leaf building facades that facilitate natural ventilation while providing sufficient sound insulation. Realization of natural (window) ventilation is in some instances difficult due to a number of factors. Thereby, noise pollution (especially traffic noise) plays an important role. To address these issues, the project explored innovative solutions in terms of facade constructions for concurrent natural ventilation and noise control.

SmallWindPower@Home - Impact assessment of building-mounted small wind turbines on performance, people, building and environment
Within the project SmallWindPower@Home the impact of complex obstacles on the local flow pattern as well as on the inflow and the performance of different building-mounted small wind turbines (SWT) will be evaluated. Furthermore the effects of these building-mounted SWT on the building, the resident people and the direct environment will be analysed.
In the course of DALEC an online concept evaluation tool for architects, building engineers, lighting designers and building owners was developed. Although easy to use, the software accounts for the complex thermal and light processes in buildings and allows a simple evaluation of heating, cooling and electric lighting loads. Not only energy, but also user behavior were considered (e.g. in terms of glare protection) and visual and thermal comfort were evaluated. This novel and innovative, holistic approach makes sustainable and energy efficient building design possible for new buildings as well as refurbishment.

PVOPTI-Ray, Optimization of reflecting materials and photovoltaics in urban environment with respect to energy balance and bioclimate.
Within the scope of the project PVOPTI_Ray the influence of reflection and energy balance on the performance of building integrated photovoltaics (PV) in complex urban environment have been investigated. Equally the influence of PV modules and of the energy conversion of solar energy at the PV module surface has an impact on micro climate and therefore also on pedestrians who are exposed to the radiation fluxes. This was also investigated.
The goal of FitNeS is the development of modular split heat pumps with compact and silent façade-integrated outdoor units for heating and domestic hot water preparation (and optionally cooling in combination with PV). The outstanding features of the concept are a modular design with a high degree of prefabrication and representing a visually and architectonically attractive, economic and sustainable solution for both new constructions and renovations. One of the main development goals is the minimization of sound emissions by means of optimized flow control.
This project targets the further development of windows with integrated vacuum glazing. Such glass products regularly feature a very low Ug-value, and their dimension is in comparison to insulation glass thin and light. As such, these products offer a new alternative for highly-insulating window constructions, and thus also for energy-efficiency measures in buildings. The project is based on the findings of a previous exploratory project (MOTIVE) and focuses on the construction of functional prototypes of vacuum glass windows together with business partners.
