IEA-EBC-Annex 61: Development and Demonstration of Financial and Technical Concepts for Deep Energy Retrofits of Government/Public Buildings and Building Clusters

Deep Energy Retrofit is of utmost importance, as buildings are characterised by very long renovation cycles. Based on this issue from energetic point of view unambitious retrofits cannot gain long-term climatic and environmental benefits. To increase renovation rates and to optimise the present energetic standards in the renovation sector strong incentives on technical – and […]

Air_plus: Simple ventilation systems – energy- and resource-efficient, affordable for the renovation of residential buildings

The relevant costs, existing of additional planning-, installation-, maintenance- (change of filters, cleaning, fire-protection) and running costs (high power consumption), are a big challenge for the housing associations to invest in residential ventilation systems. These costs, in their view, bear no proportion to the energy savings and user satisfaction. During the last years there has […]

IEA SHC Task 52 – Solar Heat and Energy Economics in Urban Environments

The ambitious energy and climate policy goals set for 2020 and 2050, like the roadmap of the European Commission of a low-carbon-economy require, especially in urban areas, a global transformation of the energy system. Hence, beside efficient technologies, a reduction of the energy consumption by changing our consumption patterns is needed. Concurrently, the potential of […]

Optimisation of primary energy consumption of solar (thermal) cooling plants by means of efficient technology and innovative control strategies

The R&D Project „Optimisation of primary energy consumption of solar (thermal) cooling plants by means of efficient technology and innovative control strategies“ (SolarCoolingOpt) aimed to find out the optimized configurations and control strategies for solar thermal cooling plants regarding primary energy balance. A first step was the development of two improved simulation models on the […]

Combined Development of Compact Thermal Energy Storage Technologies

In the EU-funded R&D project COMTES, three technologies for the seasonal storage of solar thermal energy are being developed. The aim of the project is to arrive at storage systems that need less volume than comparable systems working with water as the sensible storage material. In one development line, the Swiss research institutes EMPA and […]

RENEW SCHOOL

School buildings are places of major public interest. Our children are educated in life’s basics, in some schools beyond that. Therefore not only the educational system itself, but also the conditions of these buildings are very important signals to the public, even to the pupils themselves. The RENEW SCHOOL project aims at retrofitting a great […]
