WHY a library of tools and guidebooks?

The IEe-library brings together in one place a range of relevant tools and guidebooks on energy efficiency, renewable energy applications and sustainable mobility. It includes items funded under the Intelligent Energy Europe (IEE) programme and a selection of instruments picked from over 2,500 EU funded projects (under Altener and Save, CIVITAS, structural and regional funds, LIFE, RTD 2002-2006, Leonardo, Phare and Concerto I-II). In addition, nationally and regionally funded tools and guidebooks have been included from the EU 27 Member States, Norway, Croatia, Iceland, the US, Canada and from some international organisations.

HOW MANY ITEMS are available in the IEe-library?

There are more than 900 tools and guidebooks in the library. The majority of items are available in more than one European language. The number of items available in the library is likely to increase due to the possibility offered to users to suggest new or updated tools and guidebooks for inclusion in the library (see section below on ‘How to submit a tool or guidebook’).

Is the IEe-library FREE OF CHARGE?

All tools and guidebooks included in this inventory are freely available and ready to download and use.


WHO IS the library AIMED AT?

The aim of this inventory is to disseminate practical 'intelligent energy' tools and guidebooks throughout Europe and beyond. Businesses, energy professionals, policymakers and interested individuals alike can profit from a wide range of freely available material to help them in their everyday work. The IEe-library is a good starting point for (future) applicants and contractors to the IEE programme, to allow their projects to save time and costs by profiting from an inventory of available tools and guidebooks. The full range of target audiences who may benefit from the tools and guidebooks contained in the library can be found under the question ‘Who are the target audiences for the library?’.

How can I use the SEARCH facilities?

How can I use the FREE TEXT SEARCH?
This is a simple search provided in a box at the top right of the Home page.  Users can type in any text. The system will find the word or the combination of words by searching in every field, including title, abstract, type of tool and other fields.

How can I use the THEMATIC SEARCH?
From the Homepage, browse the menu provided on the left. The menu lists the thematic categories under which tools and guidebooks have been classified. By clicking on the top level theme the system will show all the tools and guidebooks relevant to that theme. Some tools and guidebooks can be found also in the sub-themes where items can be filtered accordingly.

How can I use the  ADVANCED SEARCH?
You can search tools and guidebooks by category, type of tool, target audience and keyword.  A search can be refined by combining criteria; the more criteria you add, the more the search will be narrowed down. If you do not find what you are looking for at the first try, use fewer or different criteria.

What are the CATEGORIES of items in the library?

The themes and thematic areas covered by the inventory have been selected by the Executive Agency for Competitiveness and Innovation (EACI) on the basis of the Key Actions covered by the IEE programme and derived from observed needs.

Each tool or guidebook has been classified under a category. You can search by category either by using the thematic menu on the Homepage or by using the Advanced Search facility.

All items in the library are listed under the first thematic level (category); they are also listed within a second level (subtheme), where appropriate (e.g. if a tool can be applied across sub categories, such as in rural areas as well as in urban areas, it will be listed under the first thematic level 'Local/Regional Energy Management' and not under the subthemes).

For each of the four themes, specific thematic areas have been selected to help users in their search. The selection is based on needs observed during the past years of the IEE programme implementation.

Which COUNTRIES are covered by the library?

Most items in this library can be applied to all 27 EU countries thanks to their methodology that can be easily transferred or replicated.
Additional information has been provided on tools and guidebooks when the item includes country-specific information (e.g. datasets, legislative or economic analysis for a given country, or implementation specific to a particular country). In addition to the 27 EU countries, Norway, Croatia and Iceland are also covered by the library. Tools and guidebooks found in the US and Canada are included in the database; however, the classification below can not be deployed. The list of countries and their acronyms covered by the IEe-library is provided in the table below. You can search by country using the advanced search facility.

Which TYPES OF tools are included in the library? 

To allow you to find specific types of tools and guidebooks more easily, each item has been classified as up to three types of tool or guidebook. You can search by type of tool using the  advanced search  facility.  Remember that you can refine your search or make an alternative search by using the keywords!

Type of tool Description Note
Blue print -Action plan model  A model or prototype with a detailed methodology for the achievement of a specific objective. A blueprint is a model where the steps to be taken are clearly outlined, including methodological, analytical issues, and resource requirement and include lessons learned (only case studies and best practices with these characteristics should be included). An action plan model is a blue print for action plans, an action plan is a scheme or programme for future action to achieve objectives.
Benchmarking tool A tool which allows something to be measured or judged against a specified standard or best practice example(s). It should enable a comparison to be made, success to be judged and also possible improvements to be made. It should include information which allows the target audience to compare different results, therefore it could include technologies search engines.
Calculation toolA tool to assist a target audience in making calculations.
ChecklistA list of items to be noted, checked, or remembered, eg during the execution of an activity or task.

How does the RATING system work?

The library features a rating system, where users can rate each tool on a scale of 1 – 5 stars (5 stars being the best). The ratings will help to guide other users towards the best tools. To rate a tool, simply click on the appropriate number of stars at the bottom of the tool’s page. You can only rate each tool once.The average user rating is displayed on the tool’s page, and in the search results. The current top 3 user rated tools are also displayed on the right side of the Homepage.

CAN I SUGGEST A TOOL for inclusion in the library?

If you like to share a tool or guidebook with interested stakeholders across Europe you can suggest it for inclusion into the IEe-library by using the ’Send Us a Tool’.
