have been studying the combinations of heating and cooling technologies from the point of view of their application, the climatic conditions in which they are to be used, their energy costs and their social acceptance with a view to developing the most efficient, cost-effective solutions for the new renovation packages and kits. In this respect, a number of technologies
that ease the refurbishment process have also been elaborated.
Hydronic modules Connecting a number of components in heating and cooling systems that make use of a number of RES is usually a hard task, which might result in a poor installation due to design and installation errors. Within iNSPiRe, EURAC
components like very low enthalpy water heat pumps (around 30°C in heating and 18°C in
cooling mode), without the
inhabitants or users of the building having to leave during renovation works. A detailed market survey of the available
radiant ceiling panels has been carried out to gain a better understanding of their weaknesses in terms of manufacturing, installation and maintenance. Based on these findings, two distribution kits are under development. The first is specialised for residential
and Manens-Tifs are
developing hydronic modules, allowing for the easy integration of different components and different configurations. The basic idea is to develop modules that allow a number of components to be integrated together allowing flexible system configuration,
buildings: it will connect a low-cost lighting solution - average lighting requirements are encountered in this kind of application - and radiant ceiling modules. Then, after envelope renovation, heating and cooling requirements are reduced and so radiant ceiling performance can be downgraded. Effort is also spent to reduce installation time by manufacturing pre- shaped elements fitting to
the rooms’
contour, which can be easily and precisely fastened on to the ceiling.
AT A GLANCE Project Information
Project Title: iNSPiRe: Development of Systemic Packages for Deep Energy Renovation of Residential and Tertiary Buildings including Envelope and Systems
Project Objective: iNSPiRe will tackle the problem of high-energy consumption by producing systemic renovation packages that can be applied to both residential and tertiary buildings. The renovation packages developed by iNSPiRe aim to reduce the primary energy consumption of a building to lower than 50 kWh/m²/year. Suitable for a variety of climates, these packages will ensure optimum comfort for the building users.
Project Duration and Timing: 4 years, October 2012 to October 2016
Project Funding: €7,499,998

which is adaptable to the needs of the different buildings and RES availability. Additionally to the hydronic stations already available on the market that allow easy hydraulic connection of the developed elements
and allow components to be
connected from a control-logic point of view: solutions are also being developed including detailed temperature and energy monitoring, easy configuration and active elements (pumps and valves) controllers.
Ceiling radiant panel The company TRIPAN is responsible for the development and design of energy distribution kits that incorporates a prefabricated modular ceiling compound that
includes lighting and low enthalpy
water heating and cooling systems. Usually, radiant ceiling heating systems
are more expensive to run than conventional radiators or even to radiant floor heaters. However, in refurbishment applications, the use of radiant ceilings is often the only available solution that allows for the use of heating and cooling
100 The second distribution kit is being
specialised for office applications. This will connect the radiant ceiling to a more expensive lighting system that in turn produces higher energy savings. Moreover, the radiant element will be used to redirect natural lighting from windows throughout the offices. In this way, the higher cost for radiant
ceiling manufacture will be absorbed by their multi-functionality – there will be reduced transportation, while the installation
and heating, cooling lighting costs will also come down.
Holistic approach Every one of these innovations will help to incrementally push towards the final goal of a 50 percent energy consumption reduction in older buildings. This holistic approach to renovation being adopted by iNSPiRe means that by making savings in energy consumption in all possible aspects of a building, a huge overall benefit can be felt when they are brought together in one package.
