solSPONGEhigh - High solar fraction by thermally activated components in an urban environment
Within this project the intensive use of thermally activated building elements (TABs) as an additional thermal storage in different buildings, with solar technologies (thermal, PV) preferred for energy supply, was investigated. The aim was to activate and use the thermal storage potential that is immanent in the building elements and thereby achieve solar coverage of the building's heat demand of nearly 100 %.

urban pv+geotherm - Innovative concepts for the supply of large volume buildings/ quarters with PV and geothermal energy
The use of renewable energies in inner city locations is mostly linked to higher costs andconsidered as problematic. The aim of this project was to optimize (cost and energy) heating (and where required, cooling) using geothermic and photovoltaic for an urban, densely-built development area. With the project´s findings it will be easier to ecologically and economically plan the use of renewable energies especially in urban areas.
ÖKO-OPT-AKTIV - Optimised control and operating behaviour of thermally activated buildings in future urban districts
Development and simulation of scalable, distributed control strategies for the use of the storage effect of thermally activated components in buildings of future city districts for their energy supply by an energy centre.
DALEC - Day- and Artificial Light with Energy Calculation
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.
An innovative approach for facades with optimised noise protection and natural ventilation
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.
Indicators for urban areas – for construction, operation and mobility in climate-friendly areas
Development and coordination of indicators for energy and ecological evaluations of urban areas based on the Swiss 2000-Watt certification system. The results will be used for the development of a quality assurance system for urban areas similar to the klimaaktiv declaration for buildings and the e5 certification for communities.
Photonic Cooling – Efficient cooling of buildings through the use of photonic
Within the scope of the project a photonic cooling approach was investigated and evaluated in terms of feasibility and cost efficiency for building applications. In particular cost-efficient photonic surfaces and concepts were investigated which need to have a high reflectivity in of the incident solar radiation (>97%) and a high emission coefficient within the spectral range of 8 – 13 micrometer in order to enable the emission of heat into the sky.

Examination of the suitability of street space or other paved or not paved surfaces in urban areas for promoting renewable heat from solar radiation. Thus offers a high potential for increasing energy efficiency and conserving resources in urban contexts. Besides, the dissipation of heat from large solar-heated surfaces promises to prevent urban heat islands.
