Longlife

Longlife is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Longlife rather than just read about it. In short: Longlife (Longlife - Sustainable, energy efficient residential buildings in regard to European requirements and innovative technologies in the Baltic Sea Region) is a transnational project in the Baltic Region. It is funded through the EU programme Baltic Sea Region 2007-2013.

Key takeaways

Longlife belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Longlife to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Longlife from memory before moving on to harder problems.

Reference excerpt

Longlife (Longlife - Sustainable, energy efficient residential buildings in regard to European requirements and innovative technologies in the Baltic Sea Region) is a transnational project in the Baltic Region. It is funded through the EU programme Baltic Sea Region 2007-2013. Longlife contributes to the EU Strategy 2020 framework to reduce energy consumption.

Longlife project Longlife is developing standards for sustainable, energy efficient building in the Baltic Region and harmonizing the different construction technologies. This includes standards for sustainability, procedures for planning, building permits and tendering and funding in the Baltic Region. One of the goals is to make the Baltic Region more competitive. In the Longlife project partners from Denmark, Lithuania, Poland, Russia and Germany are working together. Lead Partner is the TU Berlin, Institute of Architecture, Chair of Design and Structure, Prof. Dr.-Ing. Klaus Rückert. The developed standards and benchmarks are minimum requirements for sustainable buildings. Considerations are made concerning the ecological, economic and social aspects in the life cycle of a building. The design process is supported by the Longlife prototype, a catalogue of materials, components and key technologies for energy efficiency and renewable energy sources that meet the minimum requirements of Longlife, e.g. the final energy consumption of 40kWh / m² year. Longlife will demonstrate with Pilot projects that an extra effort in the integrated planning in order to minimize energy consumption and operating costs of a building life cycle is worthwhile. At the end of the planning process, the building will be certified with the Longlife Performance Pass. This performance pass includes measurable data from the building in the fields of energy, costs and qualities. The practical solutions and innovative technologies are also applicable to other building types. Together with seven other projects Longlife will develop in 2012 a compendium which shows the potential and synergy of an energy cluster. As a continuation of the project's work, the Longlife Institute e.V. was founded in September 2011.

Worked examples

Example 1 — a first encounter with Longlife

Start with the simplest possible case. Write down what Longlife claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Longlife before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Longlife ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Longlife

In research: Longlife appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Longlife in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Longlife is common in secondary-school and first-year university syllabi. It links to neighbouring topics Sustainable building, so understanding it makes those chapters shorter.
In everyday life: Look for Longlife outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Longlife in simple terms?

Why does Longlife matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Longlife?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
