Energy Management Opportunity Assessment
Executive Summary
This report presents the results of a walk-round energy survey of RSPB’s Grange Farm facilities,
carried out by Richard Hipkiss, Principal Consultant at digitalenergy on 13th March 2015. The
facilities at this site comprise 4 separate buildings as follows:
1.
2.
3.
4.
Main Farm House (Offices and Accommodation)
Green Store [Large Unheated Workshop]
Open barns/stables
Garage block
All buildings have been included within this survey.
The main office and accommodation is fundamentally a farm house that has been converted to
provide office and meeting facilities, with domestic accommodation upstairs for residential
volunteers.
The site has been selected by RSPB as typical of the converted building stock and as such is
considered to be a ‘sample’ building for the purposes of assessing energy efficiency
improvements for compliance with ESOS. Since construction this site has not undertaken any
specific assessment to identifying post construction energy efficiency improvements and
therefore the purpose of this visit is to help identify and prioritize general saving opportunities,
and renewable energy options. At a group level RSPB are committed to energy saving and have
policy and awareness measure in place.
It is believed that any observations made were indicative of normal operating practices, and
therefore any recommendations should be valid but this should be confirmed before
implementing measures, particularly where they involve capital expenditure. It must also be
emphasized that the quoted savings are estimates only and should not be relied on as a basis for
expenditure.
The energy management assessment which can be found in Appendix A is the result of a
question and answer session with Ian Dillon, Site Manager and is representative of this site and
not RSPB as a whole.
In summary, improvement recommended are largely limited to the Main Farm House and the
operational management of energy consumption where control measures are not in place. This
said as can be seen in the summary approximate savings of £1,500 per annum could be
achieved with simple measures.
It is worth noting that whilst the cost of the monitoring and targeting would not provide an
economic simple payback it is an essential action to underpin the success of an energy
awareness campaign and therefore in considering actions one and two collectively a simple
payback of two years would be more reasonable.

3. Site Overview
3.1 Location and History
The buildings at Grange Farm are located of the main High Street in the small village of Knapwell
The buildings marked with no entry signs are either no longer on site or not part of the complex.
The main office and accommodation is fundamentally a farm house that has been converted to
provide office and meeting facilities, with domestic accommodation upstairs for residential
volunteers. The building extends to approximately 630m2 GIA.
The building is hence used 24/7 365 day a year, the residential volunteer(s) are responsible for
overall energy management, although the heating is on time control.
Heating to the building is provided by a single oil boiler via radiators, hot water is also sourced
from the same boiler. There is no zoning of the distribution system, all radiators are on at all
times but are fitted with TRV’s.
Page | 9
RSPB – Grange Farm
Energy Management Opportunity Assessment
The oil consumption is monitored via a wireless system (photo above) but this is primarily for
monitoring tank levels and can alarm to alert occupants to low stock.
Internal lighting is provided by a mix of fittings dependent upon area served. The lighting types
employed are:
T8 Fluorescent 58W
Incandescent bulbs – 100W
All internal lighting is manually controlled.
All other buildings on site are unheated and have similar lighting, all replaced within last 10
years.
A PV system has been installed on the roof of the Green Store approximately 3 years ago.
External lighting is halogen spot lighting with presence detection.
There is no sub-metering installed on the site with only fiscal meters to record consumption of
electricity and generation from the PV array, manual meter readings are not taken regularly.

RSPB – Grange Farm
Energy Management Opportunity Assessment
In the left hand photo above there a three fiscal meters, upper left is redundant, lower right is
the electricity import and upper right is the electricity export meter. The right hand photo show
the PV generation meter for the system installed on the Green Store roof.
3.2 Energy Consumption Information
The site uses grid electricity with contribution to the demand from a roof mounted PV array and
bulk delivered heating oil, the oil is for space heating and domestic hot water.
Consumption below is for the year 1st April 2014 to 31st March 2015 as per the ESOS
reporting period.

There are minimal gaps in the AMR electricity data resulting in <1% error. As no delivery notes
or tank reads are available oil consumption has been calculated from a benchmark figure
produced using the display certification methodology with the building split approximately 60%
office and 40% accommodation.
3.2.2 Estimated End use consumption
In the absence of detailed sub metering data it is not possible to accurately profile end use
energy, however the following pie chart estimates the end use based upon site assessment.

3.2.2 Data Analysis
3.2.2.1 Electricity (Utility Analysis)
A more detailed on the electricity consumption that is available via smart meters gives some
indication in to the effectiveness of energy management on the site. Looking at the total monthly
consumption it can be seen that the peak usage months (red line in chart a below) for electricity
is January.
The lowest usage month is March, as shown by the green line in chart b below. A full analysis of
total monthly electricity consumption can be found in Appendix B2.
Chart b: Total Monthly Consumption [Electricity]
Consistent with the peak total usage an analysis of the average consumption per day as per
chart c below indicates that January has the highest daily average of 349kWh, and the peak daily
consumption of 110kWh occurring in December.
Page | 12
RSPB – Grange Farm
Energy Management Opportunity Assessment
Chart c: Daily Average, Min and Max Consumption [Electricity]
May produces the minimum daily consumption within the period of 10kWh. Chart b, below,
shows the profile for Christmas day that gives an indication of the base load of the building.
Chart d: Daily Consumption Profile 25th December 2014 [Electricity]
A single day profile on the 25th December shows that the base load for the building is
approximately 1.2kW, this graph also indicates that on non-working days the base load is met by
the on-site PV generation.
A full analysis of total single day profile of electricity consumption for December 25th 2014 can be
found in Appendix B7.
In contrast to chart d, chart e below shows an average daily profile in the month of April 2014.
This is representative of the full year.
Page | 13
RSPB – Grange Farm
Energy Management Opportunity Assessment
Chart e: Daily Average Consumption Profile April 2014 [Electricity]
The peak consumption is 2.2kW, at 7.30pm indicates that during the day the PV system
contributes significantly to the load and that peak consumption is likely to be related to the
volunteer residential accommodation on the first floor of the farm building.
Even though the PV system meets a significant proportion of the base load, even in the winter, a
key part of the energy awareness opportunity would be for staff to understand what makes up
the base load and peak load of the site (covered in opportunity section). Thus giving the
opportunity for the PV system to contribute to more of the load and potentially increase the grids
export from the PV system.

3.2.2.2 Heating Oil (Utility analysis)
As no delivery notes or tank reads are available oil consumption has been calculated from a
benchmark figure produced using the display certification methodology with the building split
approximately 60% office and 40% accommodation.
As a benchmark figure has been used no analysis is appropriate.
3.2.2.4 Heating
The heating and domestic hot water is provided by the oil boiler, however without metering data
it is not possible to analyse the operational efficiency of the heating system against degree days.
On the left hand side of Chart j and k below shows what the profile of heating degree-days
(pink) with actual (blue) and forecast (green) consumption overlaid. As the consumption is not
heating the result is not overly useful. The right hand side of chart j does however show an
element of control, suggesting that the non-heating electricity is consistent throughout the year.
Chart j: Analysis of consumption against Degree Days [Electricity]
3.3 Benchmarking
Benchmarking is a useful exercise to understand energy use and spend so it can be compared to
use after the facility has made changes to its management and operations. Data collected is
used to calculate annual consumption in kWh for each fuel (oil and electricity) and then divided
by the floor area to get energy consumption in kWh/m2 for each fuel.
Using the total energy consumption and the recorded floor area of the building the actual relative
consumption for the building is as follows:




Combined benchmark for all utilities is unknown as no oil data available
Electricity benchmark is 13.7 kWh/pa/m2
Heating benchmark is unknown as no oil data available
The typical benchmarks for a visitors centre using benchmarks in CIBSE guide TM44 (also used
for the DEC ratings) are quoted at:
 Heating – 164 kWh/m2/year
 Electricity – 101 kWh/m2/year
Page | 16
RSPB – Grange Farm
Energy Management Opportunity Assessment
The individual fuel benchmarks indicate that electricity is well controlled, the focus of energy
efficiency should be on reduction in the heating demand and improvement of the system
efficiency.
Recording actual consumptions and normalising against floor area allows:


Year on year can help measure the effects of efficiency campaigns
National benchmarks allow you to see how you are doing compared to other similar
charities and against other buildings within your portfolio.

4. Energy Saving Opportunities
4.1 Methodology for analysis
The site has been surveyed using the methodology approved by communities and local
government in the operational rating process. The method sees the assessor reviewing the areas
of the site to consider all areas of potential energy savings and using knowledge and experience
to methodically to identify where improvements can be made.
4.2 Criteria for ranking opportunities
Energy reducing opportunities have been ranked on order of importance in terms of delivering
savings balanced against the impact of savings.

Detail
The site currently uses an oil fired boiler for heating and hot water. The boiler, whilst serviced
regularly has a poor efficiency rating and is poorly insulated. Whilst there is no scope for a
natural gas boiler a more efficient oil fired or small scale biomass boiler would be an appropriate
replacement.
Page | 18
RSPB – Grange Farm
Energy Management Opportunity Assessment
Based upon the boiler condition and age the seasonal efficiency is estimated to be in the region
of 65%, by upgrading to a new efficient boiler of typically 92% it should be possible to achieve a
27% reduction in oil consumption which equates to 34,500kwh.
It should be noted that this is an estimate as oil consumption is based upon a benchmark figure.
Rationale
The boiler is greater than 15 years only and has poor efficiency.
Risks
Replacing the boiler could identify or create wider issues with the heating distribution system,
even creating leaks from better pressure and efficiency.

Within the main building the heating is on one single circuit, however different parts of the
building are used at different times of the day. The upstairs is used evenings only, where the
majority of the downstairs area is only used during office hours or in some cases once a week.

Rationale
Zoning the heating will reduce consumption.

Due to the fabric of the building a risk from zoning would be that the overall building envelope
does not retain sufficient heat.

Lighting is generally efficient and well controlled but there is opportunity to replace the existing
T8, incandescent and halogen lighting with equivalent LED replacement. As all lighting is well
controlled there is no cost justification for a blanket replacement and it is recommended that
replacement only takes place on failure of the existing lamps.
Rationale
Reducing the light rating will reduce energy consumption.
Risks
Equivalent light output LED lights are available so there should be no reduction in lighting levels.
Implementation Stages
1. Create a lighting asset register with record of installation date
2. Develop a predictive maintenance plan to enable planned replacement.
3. Replace existing T8, incandescent and halogen with LED on failure of existing lighting

Detail
A programme to identify current energy consumption and to establish patterns of usage should
be undertaken. The first step in such a programme is to fully understand what data is already
available to the visitor centre, and to apply analysis in a timely and appropriate manner. Degree
day analysis and plotting electrical data should be undertaken as minimum levels of monitoring,
along with the existing regular routine of meter reading.
Whilst M&T Programmes can generate savings in excess of 10% of overall consumption its
application at this type of facility is limited and should primarily be used as a method of detecting
consumption anomalies, comparison with other facilities and utility bill verification. On that basis
a conservative saving of 2% of the electricity consumption is considered to be achievable by
implementing basic M&T on this facility. AS heating appears to be well controlled this has been
excluded from the potential savings.
The type of analysis possible with M&T would include that mentioned in section 3.2 and 3.3, and
all reports in Appendix B have been extracted from a monitoring and targeting package called
digitalenergy professional (www.digitalenergy.org.uk)
In order to obtain real-time information a low gateway would be installed on the existing meters
to record and alarm on consumption.
To assist in the investment the government makes available Enhanced Capital Allowances. More
information can be found in appendix C (attached)
Rationale
Accounting for energy consumption needs to go beyond the financial appraisal of invoices. It is
not possible to set meaningful targets for a reduction in energy use if it is not first understood
what level of consumption takes place. Regular analysis of consumption data will allow the team
to compare Grange Farm with other facilities and will help identify consumption anomalies.
Risks

Energy Management Opportunity Assessment
Analysis of energy data can be complex. Initial data analysis should reflect as simply as possible
against another measure such as temperature or time to avoid “analysis paralysis”.
Implementation Stages
Evaluate existing data sources to identify the most appropriate methods of initial data analysis. It
would be prudent to begin your M&T programme by fully utilizing the data that already exists.
1. Obtain proposals to automate existing metering installed.
2. Enable metering within aM&T package by end use measured and/or area
3. Configure reporting to be receiving by management and energy champions for review
and action.
4. Set energy targets for each area of the building/application.
5. Use exception reporting to identify and act upon profile deviation.

Detail
All building users (both staff and volunteers) should be aware of their impact on efficiency of the
building to enable them to positively contribute to energy efficiency. Currently there is good
knowledge of the building design but operation is left to automatic systems where not always
appropriate.
It will be important to implement Monitoring and Targeting to educate occupants of actual
patterns and actual show the results of manual override to turn off systems.
Rationale
If building users are aware of the organisations aim relating to energy efficiency and the how
they can contribute towards energy efficiency then savings can be achieved. An estimated 2% of
total consumption based upon the assessment.

Impact of engagement and awareness campaigns reduces over time requiring re-enforcement at
regular intervals.

5. Renewable Energy Options
The visitor centre already benefits from a biomass boiler and ground source heat pumps for
heating and hot water, selected at design stage. The remaining technologies have been assessed
and highlight for further consideration. The other options have been discounted on technical
reasons.
Assessment Summary of potential renewable technologies
The recommendation is to further explore ground source heat pumps and biomass boilers.
Ground Source Heat Pumps
Ground source heat pumps may be viable for this site but traditionally they generate a low grade
heat which would normally be linked to under floor heating. As this site has direct electric
heating the infrastructure to introduce a ground source LTHW heating system does not exists
and implementation costs may make this unviable.
Biomass
Page | 24
RSPB – Grange Farm
Energy Management Opportunity Assessment
The reserve generates a considerable amount of material which could be utilised in a biomass
solution; however, as this is not in a pelleted form significant manual intervention would be
required. Wood burning stoves could be introduced and this could be a low cost solution but
would require continual actions from staff to ignite and feed with fuel.
