Building energy
We aim to use renewable heat sources for all buildings owned by NHS Golden Jubilee by 2038. NHS Golden Jubilee has 1 building hosting the NHS Scotland Academy (alongside NHS Education for Scotland), Golden Jubilee University National Hospital, national Centre for Sustainable Delivery, Golden Jubilee Research Institute and Golden Jubilee Conference Hotel.
In 2023/2024, 7,859.75 tonnes of CO2 equivalent were produced by NHS Golden Jubilee use of energy for buildings. This was an increase of 14.21% since the year before.
In 2023/2024, NHS Golden Jubilee used 39,448.46 MWh of energy. This was an increase of 11.49% since the year before.

In 2023/2024 we undertook the following projects:
| Project description | Energy savings (kWh) | Carbon reduction (t/CO2e) |
|
Electronically Commutated (EC) Fans • 9 no. air handling units received replacement fans |
6,480 | 1.46 |
|
LED Lighting Replacement • Meeting rooms • Ultrasound • Academy • Outpatients • Linen Room |
56,764 | 12.77 |
| Totals | 63,244 | 14.23 |
Table 5
What are we doing in 2024/2025 to reduce emissions from building energy use?
• Communications campaign to encourage staff to switch off lights and equipment when not used.
• Review heating and cooling set points via the building energy management system to establish efficiencies.
• Continue to replace old light fittings with LED utilising maintenance budget and own technical Staff where feasible.
In 2024/2025 we plan to undertake the following projects:
| Project description | Energy saving (kWh) | Carbon reduction (t/CO2e) |
|---|---|---|
|
Electronically Commutated (EC) Fans • 6 air handling units received replacement fans |
3,600 | 0.81 |
|
LED Lighting Replacement • Engineering Office • Corridors • Stairwell 4 • Binstore NSD • Radiology booking office • Generator switchroom • Pharmacy |
126,144 | 28.38 |

4,500 | 1.01 |
| Lifts • 8 lifts • Lift cars, controllers and lighting | 7,568 | 1.70 |
| Totals | 141,812 | 31.90 |

What projects are we planning for the longer-term to reduce emissions from building energy use?
Where funding is available, NHS Golden Jubilee has identified a number of projects which would reduce our emissions. These include:
| Project description | Benefits |
|---|---|
|
Sub metering - Electricity • 9 HV breaker and 6 load centres • Upgraded and linked to Building Energy management System (BEMS) |
Ensure compliance by upgrading old kit and provide a platform to monitor energy consumption accurately |
| LED Lighting Replacement | The site has a large mixture of t8 and t5 fittings. Not only are these high energy users, purchasing is becoming more difficult due to non-manufacturing of this type of lamp. |
|
Variable Speed Drive Replacement • Replace 36 dated variable speed drives to modern/intelligent variable speed drives. |
Estimated annual savings: • Energy (kWh) = 1,067,708 • Carbon (t/CO2e) = 240.22 |
|
Electronically Commutated (EC) Fans • Replace 37 remaining fans to air handling units |
Payback period is estimated at 24 months with energy saving up to 70% compared to AC fans. |
|
Solar PV • Feasibility study to establish benefits of Installations to all south and east facing pitched roof areas |
• Reduce reliance on grid electricity • Free up maximum capacity |
