A friend and I were discussing Energy Efficiency Rating and Enviromental
Impact (CO2) Rating as he is thinking of moving houuse. We have both seen
the results as shown on estate agents literature but doing various searches
on the web, we can not find out how these surveys are carried out, only that
CFL's, double glazed windows add to the scores.

Anyone got any concrete knowledge on the scoring system please.

Plenty of websites say that we can go on courses for X amount of £'s.

Kindest regards,

Guessology. A house I know has single thickness concrete walls
(1930's probably) and no more than 1inch of ratty fibreglass in the
loft with much missing. The roof was unlined so had a permanent gale
blowing through it. The "independent surveyor" took 20 minutes and
£90 to declare it had a cavity wall, modern insulation, low energy
lighting (there was none) and gave it a D rating.

I had to have one done on the holiday apartment we let. Absolute waste of
money, and the local authority agree it is!
The guy admitted he could only judge by what he could see and he can't see
the insulation in the cavity or floor! As the boiler is in the main house he
didn't look at that either!

It's all bull**** and handwaving.

Because that's where the money is ...

To people who know too much, it is a sad fact
that they know how little is really possible -
and how hard it is to achieve it.

The calculation methodology is called RDSAP (Google will tell you more) -
reduced data standard assessment procedure. SAP is the full calculation, used
for new homes where you have all the data available.

The rating is a function of the estimated CO2 output per year arising from
energy used for heating, hot water and lighting. The basic calc starts with
the fabric loss and assumed ventilation losses; hot water usage is a function
of floor area. There are all sorts of interplays within the calculation:
larger windows will increase the heat loss, but also increase solar gains
(particularly if south facing) and reduce the need for lighting. A larger hot
water cylinder loses more heat, but some of this heat useful heat and so on.

I looked at a few online for my neighbours and parents' neighbours, the
EPCs don't differentiate between condensing/non-condensing boilers, they
make assumptions about presence/absence of underslab insulation, if
they're not allowed to look in the loft, presumably if they can't see
any "plugs" they assume no cavity wall insulation too?

Since they're crap, you may as well just spend the least possible £35 on
one!
