Hi All,
We are looking for some advice regarding the SAP calculations (part L), overheating calculations (part O) and Water efficiency calculations (part G) that our building control have asked us to provide.
This is our first time building a new house and we are building a 2-bed adapted bungalow for my disabled wife in Lancashire.
We had our building regs plans drawn up in May 2022 and the plans state a 100mm full fill cavity with Drytherm and we are thinking of changing the block and beam floor for the Litecast EPS floor system, so we are not sure if the plans are good enough to submit for SAP calculations.
We have been delayed from stating due to the local authority discharging planning conditions and then requiring ground gas monitoring which took 3 months to complete.
We can’t find on the net any criteria that is needed to get a pass on the SAP calculation so we don’t know if we will need to have new drawings done and whether we will have to plan to have solar and/or ground source heat pump installed.
We don’t want to install a lot of unnecessary additions to the house just for the sake of passing the new conditions for building regs.
We would appreciate any advice or recommendations to navigate through this minefield of building regs.
Many Thanks
