Building Energy Modelling

John Herbert
Registered Energy Assessor (REA)
Energy simulation modelling allows different ideas and combinations
to be tested in the computer before the first brick has been laid.
Considering double glazing? free cooling? heat pumps? the annual energy
impact can simulated and the results analysed, providing more accurate
investment guidance at concept stage.

The same idea applies to retrofits, input the test parameters, lets
say improving the building chiller COP, run the energy simulation
with the new data, and compare the results, then make your investment
decisions, based on hard data.

Whole Life Time Cost Of Building
The construction cost is say 2-5% of the whole
lifetime cost of a building, that means its important to
study and optimise the whole lifecycle of the building
and its future energy costs "before" breaking ground.
Decisions are all made at the design stage, at least the
important ones, but these can be amended while the building is
still on drawing board, before concrete is poured or orders
placed.
Glazed units and windows, having a low U value (high performance)
as low as 1.5 - 1.6 W/sqm/k are available (2017) without breaking
the bank.
