# TODO
# - AIH001-03 has a loft that is inaccessible - ask Chenai about why this property didn't have access to the loft
# [Can't remember, not clear - Chenai will check]
# - AIH001-03 instead of cylinder insulation, we could install an air source heat pump but it might not be the
# best option for this property due to it being extrememly large and the walls being uninsulated. It might not
# be performant enough in the winter, when COP will be more like 1.5.
# - AIH001-03 - can add additional 1.6kWp solar PV to flat roof to get close to EPC C. How many occupants are
# in the property? Does it make sense to have such a large solar PV system (5.6kWp)?
# - AIH001-04 why couldn't the cylinder be accessed? - treating this could get to the EPC C
# - Potential measure - search for the cylinder and insulate it
# - AIH001-08 and AIH001-09, check if it's freehold - could solar work as both of these units are part of the same
# buulding [Question for Lewis & Kevin]
# - AIH001-09 - Is it not possible to install a loft hatch? [IT IS NOT, NO ACCESS - would need to accessed from
# the other unit]
# - AIH001-09 - Why is there assumed secondary heating? [Question for Lewis & Kevin]
# - AIH001-09 - Is there definitely an immersion water heater? Is this definitely the case for the other units?
# [Question for Lewis & Kevin]
# - AIH001-11 - The layout of this unit is confusing, is there roof access? [NO!!!! - It's a Sun room!!]
# - AIH001-12 - Why was there not access to the cylinder? [Sealed shut]
# - AIH001-12 - Is the need to draught proofing due to the windows? [This would be addressed by deailing with the
# windows]
# [Question for Lewis & Kevin] - [YES - ASHP!!!!]
