The most recent version, SAP 2012, came into force for building regulations compliance on 6 April 2014.
The 2009 version SAP 2009 may still be used on projects for which transitional arrangements apply, see 2013 changes to the approved documents for part L of the building regulations for more information.
The Terrain Manipulator is an attachment for the multi-tool which allows alterations to planetary terrain, both destruction and creation.
Initially acquired in Awakenings, it is the first "weapon" acquired by the player which is able to mine large mineral deposits.

The Standard Assessment Procedure for the Energy Rating of Dwellings (SAP) was developed by BRE based on the BRE Domestic Energy Model (BREDEM) and was published by BRE and the Department of the Environment in 1992.
In 1994 it was first cited in Part L of the building regulations and it has now been adopted by the UK Government as the methodology for calculating the energy performance of dwellings.
Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.
Carbon-14 has a half-life of 5,730 ± 40 years—, half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.
In both modes, firing the Terrain Manipulator drains its internal metal supply based on the current Game mode: 1%/tick in Survival and Permadeath modes and 0.5%/tick in Normal mode.
If the supply is fully depleted, the Terrain Manipulator becomes unusable, requiring recharge with ferrite elements to restore functionality. This modules overloads existing multi-tool systems, allowing the user to reshape regions as they wish.
And then either later in this video or in future videos we'll talk about how it's actually used to date things, how we use it actually figure out that that bone is 12,000 years old, or that person died 18,000 years ago, whatever it might be. So let me just draw the surface of the Earth like that. So then you have the Earth's atmosphere right over here. And 78%, the most abundant element in our atmosphere is nitrogen. And we don't write anything, because it has no protons down here. And what's interesting here is once you die, you're not going to get any new carbon-14. You can't just say all the carbon-14's on the left are going to decay and all the carbon-14's on the right aren't going to decay in that 5,730 years.
It's just a little section of the surface of the Earth. And that carbon-14 that you did have at you're death is going to decay via beta decay-- and we learned about this-- back into nitrogen-14. So it'll decay back into nitrogen-14, and in beta decay you emit an electron and an electron anti-neutrino. But essentially what you have happening here is you have one of the neutrons is turning into a proton and emitting this stuff in the process. So I just said while you're living you have kind of straight-up carbon-14. What it's essentially saying is any given carbon-14 atom has a 50% chance of decaying into nitrogen-14 in 5,730 years.
