IN2 are leaders in low energy MEP services design. Our approach to minimise energy consumption in buildings ensures that our designs contribute to achieving zero carbon in operation. Through our in-house team of sustainability experts, we can simulate and prove a building’s energy performance to ensure our designs achieve and exceed required energy targets.
The energy used in buildings is responsible for approximately 40% of carbon emissions in Ireland and up to half of all carbon emissions in the UK.
As such, building performance has a significant part to play in achieving national commitments on carbon emission reductions e.g. Zero Carbon by 2050 in the UK, and EU NZEB Directive that all buildings will be “Near Zero” Energy performance by 2050.

IN2 develop and follow industry recognised strategies to ensure new designs achieve or are future-proofed to achieve Zero Carbon in operation. This regularly includes measures such as:
- Significantly reducing energy demand with properly insulated buildings and reduced air permeability
- Mechanical ventilation with heat recovery in winter

Figure 4: Mechanical Ventilation with Heat Recovery
- Natural ventilation outside of the heating season
- Designing buildings not to use fossil fuels for day to day operation where possible
- Using on-site low and zero carbon technologies such as heat pumps and photovoltaic panels

The impact of these measures combines to provide a low energy design that enables zero carbon in operation (in combination with a decarbonised grid supply).

IN2 model and test multiple low energy solutions right from early design stages e.g. Stage 1 to ensure the principles are adopted in the building design right from the start of the project.
For example ensuring natural ventilation principles are achieved in the concept design of a building:
