Energy in the NHS - Action Areas
The general principles to be followed with regard to all Facilities and Estates management activities are set out in the carbon reduction hierarchy:
- Be Lean: turns things off, turn down thermostats, reduce the energy the amount of energy needed e.g. through insulation and airtightness;
- Be Green: source renewable energy by using CHP, district heating, local renewable generators and on-site renewable (where viable).
- Measure energy and carbon - monitor, record and analyse energy usage to continuously learn how to manage it effectively.
Building Services represent a significant proportion of energy use within the NHS, and often present opportunities to improve efficiency. In modern hospitals, ventilation can account for more than 30% of total site energy consumption. Whilst lighting can account for up to 25% of energy use it represents a much higher proportion of energy costs.
Renewable Energy and Low Carbon Technologies
Renewable energy is the term used to cover those energy resources which occur naturally or repeatedly in the environment. They include solar and wind power, biofuels, and energy stored in the ground which can be accessed using heat pump technology. Other low carbon sources of heat include energy from waste and combined heat and power (CHP).
