We’re starting to see it more across the UK that new buildings are expected to move toward net zero carbon performance and areas are already putting this into practice.
Net Zero Expectations
Greater Manchester is planning for all new buildings to operate at net zero by 2028 and is expecting buildings that are currently going into the planning stages to reflect these requirements. London has required major developments to meet net zero expectations for several years. Bath & North East Somerset now expects new homes to match their energy use with on-site renewable supply and Lancaster has set its own target for new homes to reach net zero operation by 2028. These examples show a wider national shift and more regions will begin to follow.
For architects, developers, and clients our message would be that now’s the time to start planning for low carbon buildings so that your projects are ready for the standards that are coming next.
Build Better Than The Minimum Standards
Good performance starts with the building fabric. Good thermal properties and low rates of air permeability reduce heat losses. This creates buildings that are low energy and cost less to run.
Choose Low Carbon Heat Sources
Heating and hot water generation is often the largest source of C02 emissions during a building’s life. Modern low carbon systems, especially heat pumps, provide reliable warmth and hot water while cutting both carbon output and running costs.
Generate Your Own Power
Solar panels are a simple and effective way to produce clean electricity on site, and there can still be a role for biofuel CHP systems in the right conditions. Considering the allocation of PV panels early in the design stage can increase the amount of energy generated.
Reduce The Risk Of Overheating
Smart design can help to avoid the need for mechanical cooling. Shading, well considered glazing and natural airflow help keep indoor spaces comfortable during warmer months without relying on energy hungry systems.
Ventilate Simply & Effectively
Fresh air is essential but does not always require a large central system. Natural ventilation should always be used where it suits the layout. When mechanical ventilation is necessary, small room based heat recovery units can deliver efficiency without adding complexity.
Use Efficient Lighting And Control
LED lighting uses far less energy and needs very little maintenance. When paired with simple controls, such as presence sensors or daylight dimming, lighting becomes more responsive and avoids unnecessary consumption.
Monitor Energy Use Cleanly
Sub metering helps show how different parts of a building use energy. Clear information makes it easier to spot waste, fine tune performance and maintain predictable running costs.
Store Energy When Possible
Battery systems, hot water storage and the building itself can help buildings make the most of the energy they produce. Stored energy can be used during peak periods, when the sun is not available and careful selection of external structure to retain heat energy can help improve efficiencies.
Looking Ahead
With London, Greater Manchester Bath & North East Somerset, Lancaster and others setting out their expectations for lower carbon buildings, we can see the direction of travel across the UK.
