Summary
Latest Status Report
Background
The gaseous heat transfer rate is dominant in conventional types of thermal insulation. To reduce it, energy transfer between gaseous molecules must be reduced. This can be achieved by reducing pore size, reducing pressure or by replacing the air by heavy gases (Ar, Kr, Xe).
Heat transfer in air can be reduced to zero in micro porous silica when pressure is below 50 mbar. As a side effect, radiation is also reduced to almost zero (more radiation barriers).
Therefore we need to explore these High Performance Insulation Systems because of:
- Increasing Legal insulation standards for new buildings,
- Insulation thickness is expensive (available net room space, expensive constructions),
- Low Energy Building Concepts, with even lower U-values, are getting more popular,
- Space for retrofit insulation in existing buildings is limited,
- Thermal insulation is one of the most important measures to cut CO2 emissions
Where
we need HiPTI
Long term(>25a) - Everywhere
Short and Medium Term (>10a)
Where space is costly
- To gain more net available room space
- To avoid thick expensive wall constructions in low energy buildings
(m2a)
Where very little space is available (retrofit)
- Floor heating systems, doors, flat roofs, interior wall insulation, window enlargement, water heater and duct.
Thermal insulation and VIP with identical thermal quality.
Aim
The general objective of the Annex 39 is to develop reliable components for buildings based on HiPTI. We call them HiPTI systems (e.g. facade element, door, water heater). The successful developments should lead to competitive products which are available on the market.
The main technology which will be used in the Annex are Vacuum Insulation Panels (VIP). They consist of a microporous core material, packed in a gas tight envelope which is evacuated to a pressure of about 0.1 mbar.
The project will be divided into 3 subtasks:
Subtask A: Basic concepts and materials
Subtask B: Application and system development
Subtask C: Demonstration and information dissemination
Participants: To be confirmed.
Countries so far expressing an interest include : Australia, Canada, Belgium, Denmark, France, Germany, Italy, Netherlands and Sweden.
