If Energy Storage is the answer,
what are the questions?
“We are looking for the man that can find the
right questions” Sir Arnold Robinson.

RIBA Work Stages
So when will the engineers get involved?
Energy Storage is not a cure for bad design…

What about the load profile?
What is the building for?
What is the likely demand?
What is the likely load profile?
What storage technologies are
appropriate to that load profile
and building use?
What capacity do they offer?

Storage media, mass, and gravity
Fluid filled storage weighs something…
How much, how heavy, and where is it going to go?
Does it have structural implications?
Will the Building Inspector get excited?
Batteries – Tesla weighs in at 100kg
for 5kW unit at present.
How will it be held up?
Who’s in control?
And what is the strategy?
How will it be commissioned?

What have I got?
What do I do with it?
Do I need to maintain
it?
How long might it last
between maintenance

WHAT IS A BUILDING LOG BOOK?
14
Summary of the building, its main spaces,
the major plant, the servicing strategy;
A single reference point for key information
about the building;
A key handover record;
Source of information/training for the
facilities team;
A dynamic document – it is only useful if up
to date!
