O N L I N E V E R S I O N R24-27C Table 2.1 Enhanced management and control features Feature Adjustment factor Automatic monitoring and targeting with alarms for out-of-range values(1) 0.050 Power factor correction to achieve a whole building power factor >0.90(2) 0.010 Power factor correction to achieve a whole building power factor >0.95(2) 0.025 NOTES: 1. This means a complete installation that measures, records, transmits, analyses, reports and communicates meaningful energy management information to enable the operator to manage the energy it uses. A building automation and control system specified following paragraphs 6.66 to 6.73 would meet this definition. 2. The power factor adjustment can be made only if the whole building power factor is corrected to achieve the value in this table (>90 or >0.95). The two levels of power factor correction are alternative values, not additive. Achieving the target primary energy rate and target emission rate 2.9 Provided the building satisfies the minimum standards for fabric elements set out in Section 4, the designer can achieve the target primary energy rate and target emission rate by using any combination of the following. a. Fabric energy efficiency. b. Efficient building services. c. Low and zero carbon technologies integrated in an appropriate mix. NOTE: The target primary energy rate and target emission rate are not likely to be met by using the minimum standards for fabric set out in Section 4 alone. Special considerations when calculating building primary energy rate and building emission rate 2.10 Special considerations may apply to certain classes of building. These building types include all of the following. a. Modular and portable buildings with a planned service life of more than two years (at one or more sites), follow paragraphs 2.11 to 2.19. b. Swimming pools, follow paragraph 2.20. c. Shell and core developments, follow paragraphs 2.21 to 2.25. d. Industrial sites, workshops and non-residential agricultural buildings, follow paragraph 2.26. e. Buildings with low energy demand, follow paragraphs 2.27 to 2.32. NOTE: Industrial sites, workshops and non-residential agricultural buildings with low energy demand and buildings with a planned service life of less than two years are exempt from the energy efficiency requirements.
