|  $11-4$ | Number of batteries | 1 to 4 (maximum 4) | Only if Photovoltaic array(s) present with battery storage default capacity of one battery $=5 \mathrm{kWh}$
If unknown or unable to determine, assume 5 kWh
If known capacity is 10 kWh , specify 2 batteries.  |
|  $11-5$ | Wind turbine details known | yes/no. If yes, then details:
- number of turbines
- rotor diameter

3) If it is not possible to determine the exact number of LEDs and CFLs, input the total number of LEL bulbs | Use RdSAP10-specific defaults:
- LEDs $100 \mathrm{Lm} / \mathrm{W}(9 \mathrm{~W})$;
- CFLs $55 \mathrm{Lm} / \mathrm{W}(19 \mathrm{~W})$;
- incandescent $11.2 \mathrm{Lm} / \mathrm{W}$ (60W).
If number of LED and CFL is not known, use default:
- LEL: $80 \mathrm{Lm} / \mathrm{W}(15 \mathrm{~W})$
RdSAP software should use these defaults for star ratings (see separate document giving the basis of star ratings).  |

19 ADDITIONAL CLIMATE DATA FOR ISLE OF MAN
For the purpose of RdSAP10 a new region (Region 22 - Isle of Man) has been added to the existing Tables U1, U2, U3 and U4 in the SAP 10.2 specification.
The details for Mean External Temperature and Wind Speed were provided by IoM.
Mean global solar irradiance $\left(\mathrm{W} / \mathrm{m}^{2}\right)$ on a horizontal plane was assumed as for region 8.
Isle of Man has several postcode areas (IM1 to IM9), these should be used from the postcode data in the spreadsheet.
(SAP10.2)Table U1: Mean external temperature $\left({ }^{\circ} \mathrm{C}\right)$ with added data for Isle of Man
These data are for typical height above sea level representative of the region (see Table U4).

20 RDSAP10-SPECIFIC METRICS
20.1 RdSAP10-specific SAP rating equations (referred to as EER)
Fuel prices are the same as in Table 12 of the SAP 2012 specification but replicated in Table 32 for completeness of information.  
The SAP rating for RdSAP 10 is to be calculated using Table 32 unit costs (not Table 12) for section 10a and 10 b .  
The SAP rating is related to the total energy cost by the equations:  
$$
\begin{array}{ll}
\mathrm{ECF}=\text { deflator } \times \text { total cost } /(\mathrm{TFA}+45) \\
\text { if } \mathrm{ECF} \geq 3.5, & \text { RdSAP } 10=117-121 \times \log _{10}(\mathrm{ECF}) \\
\text { if } \mathrm{ECF}<3.5, & \text { RdSAP } 10=100-13.95 \times \mathrm{ECF}
\end{array}
$$  
where the total cost is calculated at (255) or (355) in the SAP10.2 worksheet and TFA is the total floor area of the dwelling at (4) (see SAP10.2 specification).
20 RDSAP10-SPECIFIC METRICS
20.2 Carbon Dioxide emissions and Primary Energy in RdSAP10
Both $\mathrm{CO}_{2}$ factors and Primary Energy factors are the same as in Table 12 of SAP10.2 specification but replicated in Table 32 for completeness of information.  
Refer to section 14 in SAP10.2 specification for the calculation of carbon-based Environmental Impact Rating (EIR) and Primary Energy (PE).  
The Environmental Impact Rating (EI rating) is related to the annual $\mathrm{CO}_{2}$ emissions by:  
$$
\begin{array}{ll}
\mathrm{CF}=(\mathrm{CO} 2 \text { emissions }) /(\mathrm{TFA}+45) \\
\text { if } \mathrm{CF}>=28.3, & \text { RdSAP } 10 \text { EI rating }=200-95 \times \log _{10}(\mathrm{CF}) \\
\text { if } \mathrm{CF}<28.3, & \text { RdSAP } 10 \text { EI rating }=100-1.34 \times \mathrm{CF}
\end{array}
$$  
where the $\mathrm{CO}_{2}$ emissions are calculated at (272) or (383) and TFA is the total floor area of the dwelling at (4).
20 RDSAP10-SPECIFIC METRICS
20.2 Carbon Dioxide emissions and Primary Energy in RdSAP10
\end{array}
$$  
where the $\mathrm{CO}_{2}$ emissions are calculated at (272) or (383) and TFA is the total floor area of the dwelling at (4).  
The EI rating scale has been set so that EI 100 is achieved at zero net emissions. It can rise above 100 if the dwelling is a net exporter of energy. The EI rating is essentially independent of floor area.  
The EI rating is rounded to the nearest integer. If the result of the calculation is less than 1 the rating should be quoted as 1 . Environmental impact rating bands are defined by the EI rating according to Table 14 of SAP 10.2 .  
The primary energy consumption of the dwelling is calculated in the same way as $\mathrm{CO}_{2}$ emissions, using the primary energy factors in Table 32 in place of the $\mathrm{CO}_{2}$ emission factors. However, this result is not used to create a rating.
