Special Interest Forum:
Energy modelling is about getting real buildings to perform better, be
that in design, commissioning or ongoing operation. We have gathered
together three key industry leaders to discuss best practice approaches
for how energy modelling can deliver better buildings.

Optimising Supply Air Temperature Control
Of all the parameters of building performance, supply air temperature control
plays one of the most critical roles as it sets the balance between chiller energy,
fan energy and reheat energy. In spite of this it is only in the last couple of years
that simulation models have been able to represent supply air temperature
controls in a manner that reflects common practice in the field. In this talk, Dr
Paul Bannister will review the optimisation of supply air temperature control
for VAV systems, using results from an extensive set of simulations conducted
in IES covering a range of building configurations and climates.

Early Stage Simulation – Friend or Foe?
All too often Environmental Modellers are reticent to undertake modelling
at an early stage of a design – instead opting for a “meet the building code”
approach. This results in missing the greatest opportunity for impact early on
in a project, with decisions about fenestration location, shading typologies etc
being bedded in very quickly without any investigation through modelling. Given
we know as modellers that building performance simulation is an abstraction
of reality, what is our aversion to just getting on with it and providing modelled
advice to our clients? Quentin will discuss some examples of successes and
missed opportunities where modelling has been used to develop a building
and support the design teams decisions.

Weather Affects Building Performance - Simulation v Monitoring
Apart from occupant and management behaviours, weather variability is the
biggest confounding factor in comparing simulation results with metered
energy performance (e.g. NABERS commitment agreements vis a vis initial
NABERS rating). Trevor will discuss this variability and compare simulated
performance with recent actual weather and the climatically typical weather
used in most simulations. The use of actual weather data allows more
reliable monitoring of energy efficiency to prompt timely response to system
malfunction. This is illustrated by comparison of simulation results for three
archetypical commercial buildings using Reference Meteorological Year data
and the immediate past 12 months of recorded weather.The simulations are
used to generate a set of Weather and Energy Indices that are published
monthly for FM application without charge
