Objectives
The proposed project is intended therefore to create a logical follow
up of the IEA SHC work already carried out by trying to find solutions
to make the solar thermally driven heating and cooling systems at the
same time efficient, reliable and cost competitive. This three major
targets should be reached thanks to four levels of activities:
- Development of tools and procedure to make the
characterization of the main components of SAC systems
- Creation of a practical and unified procedure,
adapted to specific best technical configurations.
- Development of three quality requirements targets:
- prescriptive �deemed performance�
approach (<20kW): Manufacturers who
offer a standard packaged solution
declare the performance level of the
package under certain rating
constraints. This rated
performance can then be used in a
variety of policy interventions (eg :
award of certificates, restriction on
sale of low performance products,
thresholds for subsidies etc).
- prescriptive �deemed to satisfy
engineered� approach (>20 kW) : Where
customized solutions are more
appropriate, prescribed engineering
design and implementation requirements
can be specified to ensure the quality
of the systems from components to
operation (system, installation, etc..).
The ability to �qualify� and label
installations can be used in a variety
of policy interventions (eg : minimum
requirement for subsidies, overcoming
information barriers, award of points in
building rating schemes etc)
- performance-based approach (>20 kW):
While the prescriptive methods described
above will be useful within their field
of relevance, installers/providers of
Solar Thermally Driven Heating and
Cooling solutions must also have the
ability to innovate and offer tailored
solutions outside the direct scope of
the prescribed approaches. This
can be achieved by allowing direct
metering and verification of
performance. The ability to benchmark
actual performance against alternative
solutions can be used in a variety of
policy interventions (eg : promotion of
energy performance contracting, award of
certificates etc)
- Production of tools to promote Solar Thermally
Driven Cooling and Heating systems
