Victoria University of Wellington – Energy Strategy
1. Introduction
Since 2002, energy use at Victoria University of Wellington has
steadily been increasing. The numbers of staff and students is
increasing, the amount of occupied floor area is growing and
new equipment is always being purchased.
The combination of greater demand and higher prices has lead
to significant increases in energy expenditure. In 2006 VUW spent
$2.1 million on electricity and $900,000 on natural gas. If ‘business
as usual’ continues energy expenditure will soon exceed $4
million/yr.
Energy management has been handled by a number of staff on
an ad­hoc basis over the past few years. Several beneficial
energy projects have been completed, but a coherent direction
for energy management has been lacking. This energy strategy
provides a framework for the energy management programme
over the next ten years.
In August 2006, the University approved the environmental policy
and the environmental committee has since been established,
signalling the increased commitment by the university towards
sustainability initiatives. One of the objectives listed in the policy
states “the University will actively manage the use of energy and
utilities in order to achieve a reduced level of user demand and
more efficient use of available resources.”
The basis for this energy strategy comes from both a financial
and an environmental need to better manage energy use. The
strategy provides objectives for each aspect of energy
management and then details the actions required to meet
each objective.

2. Targets
2.1 Vision
Victoria University of Wellington will follow best practice energy
management standards to maximise energy efficiency and
minimise energy cost.
2.2 Benchmarks
It is important to be realistic about what can be achieved
through energy efficiency initiatives with the available resources.
Firstly, the current energy use of the University can be compared
to other facilities. Benchmarking should only be used as a guide,
rather than a target, as the data can vary in quality and often
does not provide a fair comparison. A common benchmark used
for commercial buildings in New Zealand is 200 kWh/yr.m2. In
2006, the University was at 194 kWh/yr.m2. TEFMA also collects
energy expenditure data which compares VUW with other New
Zealand Universities, as shown in Figure 1.
$16 $/EFTSU $/sq.m $14 $12 $10 $8 $6 $4 $2 $0 2002 2003 VUW 2004 NZ Average 2005 $200 $180 $160 $140 $120 $100 $80 $60 $40 $20 $0 2002 2003 2004 VUW NZ Average 2005 Figure 1: TEFMA energy expenditure comparisons
All of these ‘benchmarks’ suggest that VUW is currently about
average in terms of it energy use and expenditure. This suggests
that enormous energy savings are unlikely, but being ‘average’
for New Zealand still leaves plenty of scope for improvement.
New buildings around Wellington, which have been built as a
showpiece for energy efficiency, including the offices for the
Ministry for the Environment, Meridian Energy and Department of
Conservation have, or are expecting, energy use of around 100
kWh/yr.m2. It is unrealistic to expect VUW to reach that level with
its existing building stock. However, case studies show that over a
10 year period it is reasonable to target 25% savings for electricity
May 2007
p. 4
Victoria University of Wellington – Energy Strategy
and 40% savings for gas.1 This would reduce the energy index to
around 140 kWh/ yr.m2.
2.3 Ten year energy projections
Tracking the energy use over recent history, it is evident that the
electricity use has been increasing by about 6% each year, while
the gas use has fluctuated depending on climatic conditions.
The ‘business as usual’ case assumes that electricity use
continues to grow at 6% per annum and gas use remains at a
stable level. It is much more difficult to model energy pricing. For
the purposes of this projection it is assumed that the university will
be able to continue to get 3­year supply contracts for both
electricity and gas and each new contract brings a 15% price
increase for electricity and a 20% increase for gas (based on
recently observed price increases).
Any new construction projects will significantly influence energy
construction. At this stage 3 new construction projects are
planned. The expected energy use for these buildings is
estimated based on their proposed floor area – standard energy
intensity for ‘business as usual’ and nearly half that for the
‘energy efficiency’ scenario.
Developing and implementing an energy management
programme, as outlined in this strategy, will potentially generate
energy savings of 25% for electricity and 40% for gas. Greater
energy savings will be possible in the first few years of the
programme, after which savings will become harder to achieve.
The forecast energy usage and targets are summarised in table 1
and figure 2 and assume the energy savings described above.
Other New Zealand organisations have achieved similar levels of savings such as Te
Papa (30% reduction in electricity use) and AgResearch (25% reduction in energy
cost).

3. Management
Victoria University of Wellington is a large organisation with nearly 100
separate energy accounts, several tenancies and numerous metering
points. This section outlines the strategy to achieve effective
management of the energy accounts (both paying suppliers and
billing tenants) and how to best collect and process energy use data.
3.1 Administration
·
Strategy: Energy invoices will be generated, received and
processed in a systematic and efficient manner, whereby all
energy invoice data is checked for accuracy and recorded in
an electronic database.
·
Background: Every month VUW receives nearly 100 invoices for
electricity or gas. Most of these are for non Time­of­Use (non TOU)
small sites which have their meter read once a month. It is
important that an effective system is used to process the invoices
received. They need to be checked to ensure there are no errors
in the invoice (a small percentage of invoices generated by
retailers contain errors). They need to be paid quickly to receive
the prompt payment discount and need to be allocated to the
correct VUW cost centre.
·
Actions:
o Non TOU meters will be read at the end of each month
and the readings will be given to energy suppliers­ this
ensures all sites have the same billing period and there are
no estimated invoices.
o Hard copies of invoices to be sent to Accounts Payable;
scanned and emailed to Facilities Management
administrators to approve and action payment.
o Copies of all invoices to be emailed to Energy and
Technical Services, directly from the supplier where
possible, to check for errors and follow up where
necessary. The invoice data will then be uploaded into an
accessible electronic database.
May 2007
p. 8
Victoria University of Wellington – Energy Strategy
3.2 Tenancies
·
Strategy: The energy use of all tenants will be systematically
metered and invoiced where cost­effective.
·
Background: The University has a number of tenants including
cafes, bookshops etc. Most of the tenancy agreements state the
tenant is responsible for paying for energy separately from rent.
Some of the tenants have check meters to measure their energy
use and are billed by VUW, others are billed directly by energy
suppliers, others have meters but have never been read and
some have no meters at all. The energy use and billing structure
of the tenants should be reviewed to make sure the appropriate
parties are paying for the energy.
·
Actions:
o Review the tenancy agreement for each tenant to
determine responsibility for energy use.
o Determine the existing system of accounting for the energy
use of tenants.
o Develop cost­effective solutions to ensure that tenant
energy use is being billed and paid fairly and correctly.
§ NB: Energy could be incorporated into the rental
rate when the leases are renewed or sub­metering
installed and read monthly. If the tenant is estimated
to use less than $1,000/yr then metered energy
billing is unlikely to be worthwhile.
3.3 Measurement
·
Strategy: Sufficient energy consumption and expenditure data
will be collected to provide cost­effective analysis of energy
performance and potential savings.
·
Background: To effectively manage energy use, it first needs to
be measured. More detailed measurement of the energy use
allows of more detailed analysis of energy performance.
Detailed measurement is also a critical tool in identifying energy
saving opportunities and assessing the impact of energy
efficiency projects. Many resources could be used measuring the
energy use in great detail, however before the investment of
time and money is made, any proposed additional
measurements need to show evidence of adding sufficient value
to justify the investment.
May 2007
p. 9
Victoria University of Wellington – Energy Strategy
·
Actions:
o Utilise all energy measurement sources: Energy invoices,
energy retailer web­based services, metering company
data, energy purchase database software.
o Trend plant performance using the Building Management
System.
o Ensure all buildings follow guidelines for energy metering:
§ Buildings with an annual electricity use of more than
300,000 kWh should have a Stream TOU electricity
meter measuring the main supply to the building.
§ Sites (ie: one building or a group of buildings) with
annual gas expenditure greater than $100,000
should have a TOU gas meter measuring the main
supply to the site.
§ All new construction should optimise connections to
the Building Management System.
3.4 Analysis
·
Strategy: VUW will systematically gauge energy performance
and identify and quantify potential energy savings or costs.
·
Background: Accurate assessment of the energy performance
and energy saving strategies need to based on robust analysis of
the collected data. The analysis should provide a useful gauge
of energy performance; uncover anomalies in energy use
patterns or building operations and it should highlight areas to
target for energy savings. Individual energy efficiency projects
will require more specific analysis to examine the extent of
energy savings possible and how cost­effective they are. The
analysis must provide sufficient detail to guide the energy
management programme and make wise investment decisions.
The level of detail of the analysis needs to be clearly defined and
targeted to prevent excessive, unproductive analysis.
·
Actions:
o Establish a system of comparing monthly energy use with
expected use.
o Check the energy use of each major building for
anomalies on a monthly basis.
o Analyse data as necessary on a case­by­case basis for
individual energy efficiency projects.
o Where ‘negative’ trends or anomalies are identified these
will be investigated and appropriate action taken.
May 2007
p. 10
Victoria University of Wellington – Energy Strategy
3.5 Reporting
·
Strategy: Relevant information regarding energy performance
and projects will be reported through appropriate channels to
key stakeholders.
·
Background: The energy management programme should not
act in isolation of the rest of the University. The energy
performance and the results of the energy efficiency projects
need to be reported to the wider University. This includes facilities
management, the senior management team, faculty
representatives and all staff and students. The information
reported needs to be relevant to each group.
·
Actions:
o Include energy expenditure and consumption in the
monthly facilities management report to the senior
management team.
o Distribute quarterly energy performance review and
project updates.
o Prepare energy management updates to be published on
the VUW website and through staff and student
communications.
o Targeted consumption reports with action points will be
provided to Heads of School.
3.6 Energy Management Team
·
Strategy: An energy management team will effectively progress
energy management initiatives.
·
Background: The energy management programme will develop
a number of energy efficiency projects, many of which will need
input from relevant people within the University. The team should
include a lead energy manager, the asset managers, the
facilities manager, maintenance contractors and the building
management system contractors. Holding regular meetings will
provide a platform to discuss energy management initiatives and
get input and resources from all parties. It will also provide
additional impetus for the projects.
·
Actions:
o Establish an energy management team with appropriate
representation.
o Hold monthly meetings with clear outcomes targeted and
actions planned.

4. Energy Supply
The following section details the best strategies for sourcing energy with
respect to national energy supplies. The University needs to be
confident of the long term security of its energy sources and where
possible it should pursue renewable energy options.
4.1 Security of Supply
·
Strategy: The University will strategically select its energy sources
considering national supply capacity.
·
Background: The demand for energy in New Zealand is steadily
growing and placing greater pressure on our energy reserves.
Electricity is a vital energy source for the University, which is a
relatively reliable source (Wellington does not face the same
network problems as Auckland). A large proportion of the
electricity generation is from hydro­power so there is the risk of
low rainfall reducing lake levels and restricting hydro­generation
capacity. However, this is only likely to result in increased prices
rather than losing all electricity supply (both now and in the
future). The Electricity Commission was established in 2003 to
ensure that the electricity system is able to cope with up to a 1­
in­60 dry year.2
The only other energy source currently used by the University is
Natural Gas; primarily for water heating and some for cooking.
“Gas has been a major energy source in New Zealand for 30
years. Proven reserves of gas declined sharply in 2001 when the
Maui field was found to have considerably less economically
recoverable gas left than previously thought. Renewed
exploration efforts have found more gas and led to some
increases in proven reserves”.3 In the short to medium term at
least gas will be available and provides to most cost­effective
method of water heating. If gas shortages continue to push
prices higher, then alternative forms of heating should be
investigated – including using boilers with other fuel sources such
as coal or electricity and replacing hot water based heating with
electric heating systems.

p. 12
Victoria University of Wellington – Energy Strategy
·
Actions:
o Continue to use electricity and natural gas as the sources
of purchase energy for the University.
o If shortages of natural gas make it a less economically
viable energy source for the University, investigate
alternative means of heating.
4.2 Response to national shortages
·
Strategy: The University will responsibly respond to national
shortages in electricity supply to ease demand for generation.
·
Background: The combination of increasing energy demand
and climate change is placing a lot of pressure on our hydro­
electricity supply. Low­lake levels and the corresponding
‘electricity crises’ are likely to happen more often. In previous
years all central and local government funded organisations
have been asked to lead by example and save 10% during these
times. Similar requested are likely to occur again. The University
should strive to meet these savings targets and if possible exceed
them. This should be done through a combination of an
awareness campaign and technical changes to the operation
of the buildings.
·
Actions: During times of national electricity shortages the
following actions should be taken:
o Publicity campaign to request staff and students save
electricity.
o Heating and cooling set­points adjusted to less
comfortable but tolerable temperatures.
o Time schedules adjusted so that plant and equipment
shuts down for a longer period overnight.
o Lights in entry foyers and other day lit or low use areas
switched off, if safe illuminance levels can be maintained.
4.3 On­site energy sources
·
Strategy: All energy generation options will be investigated and
implemented where cost­effective and consistent with
environmental goals.
·
Background: Small scale renewable energy technologies are
becoming more available, more efficient and more cost
effective. It may be possible to both reduce energy purchases
and use a more environmentally friendly fuel source at the same
time. Two technologies which are more developed are solar hot
May 2007
p. 13
Victoria University of Wellington – Energy Strategy
water systems and small scale wind turbines; however there may
be more technologies which are suitable for VUW. The
renewable energy options discussed above have the ability to
generate energy for the University, but this is more likely to be
small scale. Cogeneration plants are being used in other facilities
around New Zealand. For example a gas fired turbine could be
used to generate electricity, and at the same time the waste
heat is captured and used for hot water heating. It warrants
further investigation to determine what systems are available
and if they would be cost­effective at the University.
·
Actions:
o Prepare a report investigating sustainable energy and
cogeneration options for the University and their potential
application, with recommendations for further action.
o Conduct consultation prior to proceeding with any
projects as necessary.
o In all cases consider energy generation options
appropriate to the need, consistent with environmental
and financial goals.
o Implement all suitable projects.
May 2007

Victoria University of Wellington – Energy Strategy
5. Energy Efficiency
The following section details the strategies for ensuring that energy
efficiency initiatives are successfully identified and implemented. The
initiatives need to consider new projects and existing facilities,
technical solutions and awareness campaigns.
5.1 Investment Criteria
·
Strategy: All energy efficiency and renewable energy initiatives
shown to have a payback period of less than 10 years, without
being detrimental to the level of service provided to users, will
receive financial consideration.
·
Background: The University can afford to invest in energy
efficiency initiatives with a longer payback period than most
organisations, as the buildings will be used by VUW for
considerable length of time into the future. Furthermore, energy
efficiency projects also provide educational opportunities for
students. However the investment in energy efficiency should be
managed so that initiatives with the greatest savings and shortest
payback are implemented first.
·
Actions:
o Develop a standard template to present energy efficiency
initiatives for funding consideration.
5.2 New design and re­fit
·
Strategy: Any renovations or new construction will be designed to
cost­effectively optimise energy efficiency, without being
detrimental to the level of service provided to users.
·
Background: The potential for energy efficiency is at its greatest
during the design of a building – it is much easier and cheaper to
incorporate energy efficient design strategies and operating
systems into a building before anything has been built. Energy
efficiency and the wider principles of ecologically sustainable
design (ESD) should be considered at the earliest stages of
design.
·
Actions:
May 2007
p. 15
Victoria University of Wellington – Energy Strategy
o Develop standard design guidelines for ESD to be used
when approaching designers. For larger projects these
may need to be specifically tailored to suit the project.
o Review plans during design process to ensure ESD is being
optimised. Where appropriate an external consultant may
be needed.
5.3 New and replacement equipment
·
Strategy: Energy efficiency will form part of the selection criteria
prior to purchasing any new piece of energy using equipment.
·
Background: As the University develops new equipment is
constantly being purchased or old equipment replaced. This
includes items such as computers, light fittings, chillers etc. When
selecting a new piece of equipment there are several factors
which effect the decision of which one to purchase. Items which
use a significant amount of energy and have a long useful life,
such as boilers and chillers, should be selected with significant
emphasis given to energy efficiency in the decision making
process.
·
Actions:
o Incorporate selection criteria for new and replacement
equipment into the ESD guidelines described above.
o Ensure procurement policy and practice at all levels
considers energy efficiency and broader environmental
issues.
5.4 Mechanical plant
·
Strategy: All mechanical plant (including lifts, heating, ventilating
and air­conditioning systems) will be operated to maximise
energy efficiency without decreasing the service provided.
·
Background: HVAC systems account for about 70% of the energy
used on site and about 50% of the energy cost. A lot of the plant
is controlled by the Building Management System (BMS), which
means adjusting the system is relatively simple. It is common to
find that HVAC systems are not operating at their maximum
efficiency and with some changes to the controls and / or some
additional equipment significant improvements can be made to
the system. To identify these opportunities requires careful
analysis of the performance of the HVAC system at the moment.
May 2007
p. 16
Victoria University of Wellington – Energy Strategy
·
Actions:
o Establish monitoring of the HVAC system performance
through the BMS.
o Assess the energy performance during winter and summer
and identify areas for improvements.
§ Focus particularly on reducing excess ventilation
rates.
o Develop strategies to improve performance.
o Ensure power factor for all buildings charged for peak
demand has a power factor of 0.95 or above.
5.5 Lighting
·
Strategy: The University will not waste energy by providing more
artificial light than is necessary or by leaving lights on when they
are not needed.
·
Background: Lighting accounts for 25% of the energy cost. The
majority of lighting fixtures throughout the University are
controlled by the users with a simple on/off switch. A more
sophisticated method of control should be investigated and
trialled to determine if the controls are cost effective and
practical – particularly in open plan areas. Secondly the
University can ensure that it does not ‘over­light’ areas, by
ensuring that lighting fit­outs are installed which do not greatly
exceed standard illuminance requirements.
·
Actions:
o Investigate options for lighting controls and trial them to
determine the level of savings possible and the
practicalities of using them.
o Systematically check illuminance levels to ensure the
standard requirements are not being greatly exceeded,
and delamp or redesign where necessary.
o Incorporate lighting design recommendations in ESD
guidelines.

Victoria University of Wellington – Energy Strategy
5.6 User Participation
·
Strategy: Energy management initiatives will gain support from
staff and students and the wider community through an
effective communication plan.
·
Background: The University will have a much more effective
energy management programme if energy efficiency gains
enthusiasm from staff and students and ultimately becomes
habitual. Social marketing techniques will be needed to
encourage staff and students to make a commitment to energy
efficiency. The University also needs to take a leadership role in
the community and be seen to be actively pursuing energy
efficiency.
·
Actions:
o Develop a communication plan which will engage staff
and students.
§ Increase awareness of energy use
§ Generate commitment to energy efficiency
5.7 Audits
·
Strategy: All buildings will be regularly audited with more detailed
investigations carried out in as needed in energy intensive
buildings.
·
Background: Energy Audits have already been completed for all
of the large buildings, excluding the Rec Centre, the Railway
Station, Student Union Building and the Karori Campus. The
numerous University houses are also yet to be audited. An energy
audit has 2 primary functions – it assesses the current
performance of the building, describing its operation and it also
identifies potential energy savings. Many of the energy saving
opportunities from the audits completed previously have already
been implemented. The previous audits also suggested areas
which could provide significant energy savings following further
investigation.
·
Actions:
o Conduct energy audits of Rec Centre, Railway Station,
Student Union and Karori Campus.
o Conduct basic energy audits of houses.
o Conduct a more detailed investigation of areas suggested
in completed audits.
o Systematically repeat audits of buildings every 6 years.
