•
ECON19 Office Type 4
A national or regional head office, or technical or administrative
Aesthetics rule and often glazed
centre
Typical
size ranges from 4000 m2 to 20 000 m2
Air conditioned
This type is purpose-built or refurbished to high standards
Reputation
versus
cost
savings
Plant
running hours
are often
longer
to suit the diverse occupancy
These buildings include catering kitchens (serving hot lunches for
Often
variable
office
hours
about
halfmulti-occupier/
the staff); air-conditioned
rooms for
mainframe
computers and communications equipment; and sometimes
A
mixed
bag
of
staff
extensive storage, parking and leisure facilities

•
80% still in use in 2050
National target to reduce by 80% by 2050
Regional target e.g. to reduce by 60% by 2025
Responsible for 1/6 UK emissions
Offices responsible for 2.2 million tCO2/year
Electricity consumption doubled between
1973 and 2000

Motivation to improve performance
• BREEAM and Building Regulations
• EPBD: EPC; DEC; A/C inspections; ESOS
• CRC, mandatory carbon reporting
• Save money

Part 1 – The Challenge
6
Essential prerequisites
• Obtain high level management buy in
• Structure to support sustainability
• Ensure reliable consumption data is available
• Establish accurate baseline data
• Energy management system
www.yesouisi.co.uk
Part 2 – How to save energy
7
Halving the demand (occupier)
• Directly responsible for 2/3 building
consumption
Top tip:
Implement consistent set point temperatures
Heating and cooling at the same time needlessly wastes energy!
www.yesouisi.co.uk
Part 2 – How to save energy
8
Halving the demand (occupier)
• Engage with building occupiers
• Organisation structure with sustainability
champions
• Turn lighting and small power devices off
• Communicate progress
www.yesouisi.co.uk
Part 2 – How to save energy
9
Halving the demand (landlord)
• Commission a building services expert
BSRIA The Effective BMS (AG10/2001)
• ItOptimise
the Building Management System
is important that a clearly identifiable person has
•
responsibility for the operation and upkeep of the
Building Management System. Without this decisions
Automated
lighting
tend
not to be taken
or thecontrols
decision making process
becomes fragmented.
• Check actual out of office hours behaviour

Part 2 – How to save energy
10
Double efficiency
• Look at full life cycle costs, e.g. Chillers
• Fit energy efficient lighting
• Ensure effective use of variable speed drives
• Make IT servers more efficient
• Explore voltage optimisation

•
•
Improved demand side management
Combined (cooling,) heat and power
Biomass boilers
On site
On site renewables
Energy from waste schemes
Procure electricity from low carbon sources
