What does TER stand for?

The consultation paper includes the following key proposals, which are consistent with policy statements and budgets issued by the government over the past two years or so: new Target Emission Rates (TERs) which would deliver a 25% saving over the previous TERs for both domestic and non-domestic buildings in line with achieving Code for Sustainable Homes Level 3; designers would be required to submit a commissioning plan for a building's services at the beginning of the project, with the objective of ensuring that its actual performance matches the design intent; a limit on heat gains for both air-conditioned and naturally ventilated buildings to prevent excessive solar gains.

Meanwhile, new Target Emission Rates (TER s) also in Part L are set to deliver a 25% saving over the previous regulations in line with achieving Code for Sustainable Homes Level 3.

For example, all plants could have 75% emission reductions (scenario A) or all plants could meet a target emission rate per unit heat input, with variable percentage reductions (scenario B).
