The objective of iNSPiRe is to tackle the problem of high-energy consumption by producing systemic Renovation Packages that can be applied to 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. The packages need to be suitable to a variety of climates while ensuring optimum comfort for the building users. iNSPiRe takes a holistic approach to renovation by making savings in energy consumption in all possible aspects of a building; by doing this a huge benefit can be felt when they are brought together in one package.
To facilitate the installation of the renovation packages iNSPiRe is developing a number of industrial products specifically designed to fit retrospectively to Europe’s existing building stock. These products will take the form of Renovation Kits. Once the project reaches its completion the kits will be placed on the market by iNSPiRe’s industrial partners.
There are SIX Renovation Kits in total and as the project reaches its half-way stage, these are now well advanced and ready for demonstration and testing in the selected demonstration buildings in Verona, Ludwigsburg and Madrid.
The innovative nature of the kits is that they integrate different retrofit components into insulated, prefabricated building envelopes. These components include HVAC systems, lighting and shading systems, pipings and ducts, and energy generation systems.
The kits have been designed for both residential and office buildings and one or more can be applied to each retrofit project. Every single innovation in each kit incrementally delivers increased energy and cost savings. When brought together into one Renovation Package, one HUGE benefit for all is delivered.
The Renovation Kits
Wooden frame, envelope insulation module, incorporating Air-to-Air Heat Pump Partners: G&M, SIKO, UIBK
Problem: Distributing ventilation, heating and cooling through a centralized aeraulic system poses a number of technical problems such as thermal losses, fire safety issues and high installation and maintenance costs. That is particularly true in case of renovations, when major construction works are needed to prepare the installation of the system.
Solution: To install decentralized systems made out of ventilation plus heat recovery plus HP directly into the envelope insulation elements, reducing to nearly zero the thermal losses, duct works, and strongly reducing fire safety requirements. Also presents easy access to the parts that have to be maintained.
Wooden frame, envelope insulation module incorporating a solar collector Partners: G&M, SIKO, VAILLANT
Problem: The installation cost of large solar collector fields on a building’s roof is high, while the installation of solar collectors on the façade is impractical if it is not done when the building is first built. Moreover, fitting the pipes needed from the collectors after any insulation work can damage the insulation while, if they are laid outside the envelope, they can look unattractive.
Solution: To pre-fabricate the envelope insulation modules (façade or roof), incorporating all the solutions as well as accommodating large solar collectors (up to 20m 2 in one piece) and the relative pipework, during the insulation installation phases.
Metal-glass façade module for office buildings incorporating the Air Handling Unit Partners: GIT, MANENS
Problem: Distributing ventilation, heating and cooling through a centralized aeraulic system poses, as we know, a number of technical problems such as thermal losses, fire safety issues and high installation and maintenance costs. Setting up heating and cooling terminals as fan coils, is usually done separately to the ventilation system.
Solution: To utilize continuous façade modules to provide contemporarily heating, cooling and ventilation through small air-heating units incorporated into the façade itself. This strongly reduces installation costs and the space needed for the technical plants.
Metal-glass façade module for office buildings incorporating a sorption collector Partners: GIT, CLIMATEWELL
Problem: In office buildings roof space is often limited for adding technical equipment. Respectively little or no space is available for solar collectors and related storage. This is a particular issue on older buildings. Traditional solar cooling systems are furthermore subject to failure and require complex and expensive pipework.
Solution: (Above) To integrate all-in-one solar collectors plus sorption chiller plus storage elements into continuous façade modules. This requires no pipework, no use of roof or technical room surface as it uses large available surfaces on the façade. Moreover, the distribution of H&C into the building is made easier.
Standardized Hydronic module for complex hybrid heating and cooling systems Partners: EURAC, MANENS
Problem: To integrate heating and cooling plants and exploit multiple renewable energy sources is a complex task, both from the hydraulic as well as from the logic/control point of view. This, on the one hand discourages engineers and installers from tackling this challenge, while on the other hand it increases design and investment costs. Moreover, the structured and reliable monitoring of the systems performance is barely reasonable within most budgets.
Solution: To design and develop a hydronic module which is standardized but flexible enough to permit the integration of virtually all systems layouts and to deploy smart electronics on board, which allow the easy control and monitoring of energy fluxes. This approach means the heating and cooling system and its control logics can be fitted at factory level and design effort is reduced to nearly zero, since standardized solutions can be provided. The system’s reliability is also enhanced through reproducibility, while installation time is reduced.
Multifunctional ceiling panel for heating and cooling, ventilation and lighting distribution Partners: TRIPAN, BLL
Problem: Radiant ceilings for the heating and cooling of buildings are normally expensive elements, due to their installation costs, although they do not require special construction work as in case of radiant floors. Moreover, they do not normally solve the problem of the ventilation distribution and pose problems when installing luminaires.
Solution: To design multifunctional ceiling panels that embed heating and cooling and ventilation distribution functions and that also integrate prefabricated LED luminaires. In this way the installation cost is spread over the three technical plants. Moreover, optimal comfort (both thermal and lighting) can be obtained by the design of the installation at factory level
