Business as usual - Design
Building use information collected during the briefing process
does not adequately focus on the Mechanical- Electrical –
Plumbing (MEP) model inputs.




Scenarios for facility use not correlated to MEP design criteria
Likewise: Equipment use cycles
Likewise: Accommodation use cycles
No energy target setting for equipment specification
Basis of Design using the specified standards


Standards are based on substantial assumptions that bear little correlation with reality
Often no actual consumption target is set – only a BREEAM quality measure.

Business as usual - Design
Basis of Design makes substantial assumptions about use and
occupancy



i.e. in the design of heating plant loads, MEP design conventionally assumes: coldest
external temperature, no occupancy and no heat gains from equipment
Poor recognition of operational cycles – i.e. reliance on standard operating schedules,
which usually do not reflect actual operations.
Inadequate understanding of factors affecting peak loads – this leads to larger plant
sizes – more chillers etc. It is not usual to use diversity of use in the calculation of peak
loads.
Monitoring and controls are usually not correlated with the way in which
the facility is operated


Managers have little control over their environment to drive down consumption
Very difficult to compare actual performance with design performance
Reporting is usual for the whole building which is insufficient to inform managers where
consumption is taking place.

Business as usual – In operation
Issues:
Indoor air temperature too high
BMS not kept up to date
BMS alarm settings incoherent – too many alarms
Incoherent temperature set point values for heating and cooling temperatures
Heating and Cooling on at same time in the same zone
Long response times for reactive maintenance
Emphasis on reactive maintenance
Leads to:
High Energy consumption
Complaints
Defective equipment not found in time
High volume of maintenance work

Energy management is continuous process
”You can’t manage, what you don’t measure”
Management of facilities’ information is key also for successful energy management, both
targets/design data and measured performance. Also intelligent analysis and reporting systems are
needed to illustrate and visualize the information.

Situation in the member states after

2008 regarding EP requirements for new
buildings and calculation methods
In the figure, the most developed available
calculation method is shown; in many
countries simplified methods may used in
parallel or for some building type

New Energy Code in Finland – July 1st, 2012
Demands for Electricity Metering
• Whole Building Electricity
• Metering of bought heating energy
• Consumption of domestic hot water
• Metering of water flow and return water temperature in domestic
hot water circulation
• Metering of usage of electricity in HVAC System
• Metering of electricity usage and produced cooling energy from chillers
• Metering of fixed lighting system
Demands for simulation tools
Energy simulation must be done using dynamic simulation
tools which have been validated according suitable standards
such as SFS EN, CIBSE or ASHRAE or according to test cases
like for example IEA BESTEST
