NEST HiLo - ultra lightweight and super integrated


NEST is a flagship project of Empa and Eawag, in collaboration with the ETH Domain – is a dynamic, modular research and demonstration platform for advanced and innovative building technologies in the heart of the Empa-Eawag campus in Dübendorf, Switzerland, due to be completed in 2015. As a “future living and working lab”, NEST consists of a central backbone and a basic grid to accommodate exchangeable living and office modules, allowing novel materials and components and innovative systems to be tested, demonstrated and optimized under real-world conditions. 

FCL -Future Cities Lab Module 1: LowExergy


As part of the Future Cities Lab Singapore, the Low Exergy Research Module aims to advance the research on Low Exergy building systems (cooling, distributed ventilation and dehumidification, lighting) in a highly dense urban context. The primary research objective is the integrated design and operation of zero emission buildings. Following the low‐exergy approach, distributed building service systems will be employed for the environmental management of building space.

OReP - Optimal Retrofit of Preserved Buildings


In the public perception there is often the expectation that historical and preserved buildings are carriers of symbolic and exemplary endeavours. Due to preservation, retrofit options however are often highly constrained. The question arises of how competing objectives, medium- and long-term priorities can be achieved. The project aims to achieve a better understanding of possible energetic improvements of preserved buildings by incorporating cultural and economic risks assessment.

ASF - Adaptive Solar Facade


The Adaptive Solar Facade (ASF) project explores novel integration of photovoltaic technology into building facades combined with occupant centered control. The aim of the research is to develop architectural systems that are energetically productive, but also respond to the desires of building occupants thereby creating increased comfort. The details of such systems are negotiated through physical prototyping. Prototyping includes: novel soft actuator technology, lightweight structural support systems, thin film photovoltaic integration, adaptive algorithms and user interaction. Additionally, custom software is being developed to predict the performance of such systems.

Torre David - Informal Vertical Communities: Energy


As part of the team involved in the acclaimed Torre David project, Winner of the Golden Lion at the Biennale of Architecture in Venice, SuAT contributed novel and exemplary concepts for future energy supply and infrastructure. Following a strategy of sustainability, SuAT tailored to improve the quality of life of Torre David’s 3000 inhabitants by providing better access to energy, water supply and vertical mobility. Therefore the efficient use of renewable and non-renewable resources and the need to maintain the social interactions existent in the site was crucial.

DPx - Design Performance Viewer


The Design Performance Viewer is a modular software framework that fuses design oriented building modeling with multi‐objective simulation, including advanced visualization and methods of statistical data analysis. It utilizes a rich building information model (BIM) and additional external databases for fast and intuitive input of parameters in an integrated design process.

PoSip - Potentials of Site and Proximity


Physical properties of a building site such as solar radiation, air flows, and visibilities are key factors to achieve human comfort and an emission-free and energy-efficient employment of technologies in buildings. A better understanding of these properties and their distribution in the urban space-time allows to identify specific potentials of a building site. Once identified, such potentials can be included in the conceptual design process supporting architectural and urban concepts that consider the site-specificity of the local resources. 

Zernez Energia 2020


The project addresses the transformation of the entire village of Zernez in the Swiss alps to be able to abandon fossil fuels for building operation. To develop appropriate strategies, ecologically as well as economically, SuAT researches and develops bottom-up modeling based on surveyed building data of 309 buildings, using clustering to identify similarities in order to develop cost- and energy optimal retrofit strategies.

InduCity - Sustainable Transformation of a City Quarter


The case study on the Siemens area in Zug provides an insight into both the prospects and barriers to implementing the 2000-watt/ 1 ton CO2 society on industrial areas. The challenge lies in the transformation of a former industrial site into a heterogeneous city quarter while retaining current production on site. The research of SuAT focuses on the acquisition of site energy and systems data, analysis of renewable energy potentials at the site and the research of optimal retrofit strategies addressing both district energy systems as well as building retrofit.

UMEM - Urban Multi-scale Energy Modeling

The development and analysis of new urban energy retrofit scenarios has to be supported by advanced simulation methods covering different interacting urban domains: the urban microclimate including urban heat island effects and climatic change, building energy systems on city quarter and urban level and human behaviour regarding energy consumption on urban level in different types of buildings. The aim of the UMEM project is to further develop existing models over the different scales, from material to urban and regional meteorological level.
