ANNEX VII
CENTRAL SOLAR HEATING PLANTS WITH SEASONAL STORAGE :
FEASIBILITY STUDY AND DESIGN
κ
Objectives ofTask
The objectives ofthis Task are todetermine the technical
feasibility andcost-effectiveness oflarge-scale ,seasonal
storage solar energy systems for theheating ofbuildings ;
toevaluate themerits ofalternative large-scale system ,
designs for collecting ,storing andusing solar energy ;and
toprepare detailed system designs for specific site para­
meters .
Means j
i
The task will beundertaken mthefollowing Phases inorder
toaccomplish theforegoing objectives : /'
Phase I :Literature survey ,development ofsubsystem and
system simulation andoptimization ofcomputer
codes ,selection ofsystem components system op­
timization ,andpreliminary designs .
Phase II :Detailed system designs forspecific site para­
meters
Phase I
Phase Iwill bedevided into five Subtasks .Close co-ordina­
tion ofthework under theSubtasks will bemaintained through
information exchange ,reports bytheOperating Agent andpe­
riodic review meetings ofallParticipants .

a
(a)§ysterrts_Studj.es arid_O ptjgigatign
(Lead Country ;Canadian Participant )
Under the guidance ofthe Lead Country ,theParticipants
will review theavailable literature concerning existing
models suitable for the analysis and optimization ofso­
lar seasonal heating systems .The validity and complete­
ness ofthese mpdels will betested bytheParticipants .
The Participants will develop computer codes for para­
meters (size ,performance ,cost ,etc.)optimization and
for simulation ofsolar seasonal heating systems based on
the best available solar subsystem and systems models .Da­
tafrom Subtasks 1(b), 1(c)and 1(d)asdescribed below
will beutilized bytheParticipants inperforming design
optimization and analysis studies using different collec­
tor ,storage and distribution subsystems ,for different
climates (weather tapes ).These studies will involve pre-
iliminary code development ,components input and system
analysis ,followed bysuccessively more refined cycles of
code development ,components input and system analysis ,
leading finally toone ormore recommended complete solar
seasonal heating systems .
Atall stages ,theParticipants will examine the economic
aswell astechnical aspects andwill establish criteria
for evaluating the systems which are developed .
ι
(b)Solar Collec torSubsystems
(Lead Country :United States Participant )
The Lead Country will co-ordinate the work oftheParti­
cipants whowill review solar collector subsystems and
who will identify those most suitable forlarge-scale
seasonal storage systems ,based onperformance andcost-
effectiveness .

-3-
The Participants will compile cost and performance data
onthe recommended collector subsystems and the Lead
Country will provide this data for use inSubtask 1(a).
Initial computer codes and system studies from 1(a)will
beutilized bytheParticipants inproviding more refined
inputs torecommendations and data oncollector subsystems ,
asafunction ofoperating temperature ,orientation ,etc..
λ
The Participants will identify requirements for technical
improvements orcost reduction .
Hgat_S torgge
(Lead Country ïSwiss Participant )
The Participants will conduct areview ofheat storage ,
concepts ancj technology and those most suitable for large -
scale seasonal storage will beidentified onaperformance
and cost-effective basis .
»
I
The Participants will compile characteristics ofrecommen­
ded heat storage subsystems and the Lead Country will pro-
 
vide this data for use inSubtask 1(a).
The Participants will also identify requirements for tech­
nical improvement orcost reduction .
Participants under this Subtask shall discuss with the
Participants ofone ormore Annexes tothe IEA Implemen­
ting Agreement for aProgramme ofResearch and Develop­
ment onEnergy Conservation through Energy Storage con­
cerning possible co-ordination ofefforts .With the appro­
val oftherespective Executive Committees ,thePartici­
pants insuch Annexes would enter into awritten arrange­
ment with theParticipants inthis Subtask setting forth
theprecise terms and conditions ofsuch co-ordination .

-4-
(d)Heat_Di stribut ion System
(Lead Country :Swedish Participant )
The Participants will review heat distribution concepts
and technology and those most suitable for large-scale
seasonal storage will beidentified onaperformance
and cost-effective basis .
%
The Participants will compile characteristics ofre­
commended heat distribution systems and the Lead Country
will provide this data for use inSubtask 1(a).Require­
ments for technical improvement orcost reduction will be
identified bytheParticipants .
!
(e)Site_Inventory_and_Prel iminary_Si te_S2ecif ic_Sys tem_Desi rjn
(Lead Country :Swedish Participant )
Each Participant wi "11conduct aninventory ofpotential
sites ,andwill develop a1prel iminary design ,including
cost analyses ,for alarge-scale solar heating plant
/with seasonal storage ,for one ormore specific sites .
They will utilize for this purpose the recommended com­
puter programs and optimized parameters developed inSub­
task 1(a).
Atthe conclusion ofPhase 1,all Participants will meet
toreview the preliminary site-specific designs prepared
*
under this Subtask .They will then select those which are
suitable for further design and evaluation work .The se­
lected .system designs may use existing technology only ,
orrequire improved components (which may bealready un­
derdevelopment orforwhich development must beinitiateq )
Inmaking their selection ofsystems forfurther develop­
ment ,theParticipants will consider thelegal and envi­
ronmental aspects involved ,aswell astechnical perfor­
mance andcost .The Operating Agent will prepare agene­
ric environmental impact assessment for Phase I(e)
systems .

-5-
PhaseII-DetailedSyste mDesign
Following the completion ofPhase I,each Participant desiring
tocontinue inthis Task will proceed with the development of
adetailed system design for specific site parameters and
costing ofalarge-scale central solar heating plant suited to
their needs atapossible site within their country .Two or
more Participants mayjointly develop such adesign and costing .
Participants not wishing tocontinue inthis Task may withdraw
upon agreement ofthe Executive Committee inaccordance with
Article 10 (g)ofthe Implementing Agreement .
Each Participant 'swork will include the conduct ofexperi­
ments asrequired ,and ,drawing upon the data andresults of
Phase I,'the selection and design ofanappropriate system .
IExtensive liaison between Participants will bemaintained during
Phase II.Participants will review all designs atsix month in­
tervals toassure information exchange and toavoid errors in
design and co-ordination .
IfthePhase IIParticipants sodecide ,theconstruction of
the solar heating plant and the evaluation ofthe performance
and cost-effectiveness ofthe plant may become the subject of
anew Annex tothis Implementing Agreement .
Tiìiie Schedule
Four years after the date ofapproval ofthis Annex .Work on
the Subtasks (a)-(d)ofPhase Iwill commence three months
after the approval ofthe Annex and will becompleted 24months
after approval ofthe Annex .Subtask 1(e)will becompleted
30months after approval ofthe Annex .Joint Phase ISubtask
meetings will beheld semi-annually .
The time schedule for Phase IIwhich isexpected torun for
18months will bedecided bythose Participants wishing to
proceed toPhase II.Phase IIdesign review meetings will be
held atsix month intervals .
