Environmental Product Declaration for a range of synthetic insulation products
Obtaining an Environmental Product Declaration (EPD) is a two-step process, implementation and verification, which must be entrusted to a EPD consultant. In the case of this family of insulation products, the implementation has been entrusted to ITeC as an authorized consultant for the DAPcons® system. The process begins with a Life Cycle Analysis (LCA) with the Simapro® software and the latest version of the Ecoinvent database, obtaining also the carbon footprint. The verification is carried out by another consultant, external to ITeC, who reviews the reports, the calculation method and the results obtained.
Homeskin project: development of high-performance insulation materials
Homeskin is a project within the European Horizon 2020 program, and its goal is the development of new products and building solutions for thermal insulation based on AABC composites, which have an aerogel content that can achieve 3 times more efficiency than standard insulation products. ITeC's has monitored how these new products fit within the European building standards so that they can enter the market as smoothly as possible.
Life Reusing Posidònia project: low environmental impact vegetal insulation
Life Reusing Positronia is an EU-funded project that involves the construction of a building to demonstrate the feasibility of producing dwellings with a very small environmental footprint. It tests building systems where thermal and acoustic insulation is provided by dried marine plants that are collected on a beach near the site. ITeC has contributed to the calculations of energy consumption and CO2 emissions derived from the building materials chosen.
Evaluation of a state-of-the-art polyurethane foam
Common polyurethane foams use hydrofluorocarbons (HFCs) as a foaming agent, a component with global warming potential. After replacing the traditional foaming agent with a new one with minimum environmental impact, it has been found that the harmonized product standard does not accommodate it. In this situation, the manufacturer can opt for CE marking the new product by way of an ETA or a certification at state level such as DAU which also addresses other aspects beyond mere performance, such as the design and execution criteria, constructive solutions and compliance with Spanish regulations.
Evaluation of reflective insulation products
The measurement of the thermal insulation performance of these products is substantially different from the methods used for traditional products, since their behaviour depends not only on the conduction and convection inside their mass, but above all on the refection on their surface. In addition, their placement on site is also different from that of the traditional solutions and it conditions deeply the effectiveness of the insulation.
Energy renovation seen as an investment
Renovating a dwelling in order to make it energy efficient is not too different from setting up a retirement plan: in both cases there is an initial outlay and the expectations for return are in the long term. The study considers a renovation budget for upgrading a standard dwelling into a C- or B-rated dwelling and estimates on the one hand the savings in the energy bill if such renovation is performed; and on the other, the benefits if the budget is turned into a contribution to a retirement plan.
Installation manual for blow-in insulation in attics
Collaboration with a manufacturer of loose insulation products on the edition of a handbook that describes the correct way to install blow-in insulation in attics. It details the preliminary checks, the perforation of the drop ceiling, the introduction of the insulation and the final quality check. It also includes a declaration model for the installer to register the technical data of the operation.
Evaluation of ETICS: external thermal insulation systems for facades
Development of regulatory requirements to assess at European level different building solutions around the ETICS concept of adding thermal insulation from the outside side of the facade. The scope includes both systems with a continuous finishing coat of mortar and those with a final facing of tiles of different materials. It includes best practices to build wall bases, cantilevers, expansion joints and corners.
Demand for thermal insulation for renovation of facades
Quantification of the potential market for energy rehabilitation of facades of residential buildings, extrapolating the amount of thermal insulation products that it generates. The study has stratified the existing housing park according to building types, location and age, and has found which are the optimal renovation systems and the thickness of insulation needed in each case. The result is a map that reflects the latent demand for insulation (quantity and type) throughout the country.
Analysis of the requirements affecting some non-conventional thermal insulation products
Among the offer of conventional thermal insulation products that are frequent in the market, some other alternatives are appearing, which need to be characterized in a rigorous manner as per the European criteria. The non-conventional insulations assessed have different origins: vegetal or animal fibers (in boards or in loose form for injection), cork (expanded granules), improved plastic foams and expanded plastic granules for in-situ injection.
