Questions that Building Services Engineers

may want to ask about Energy Storage

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…

© Chartered Institution of Building Services Engineers 2016

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

visits?

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!
