At McNair Building Design (MBD), we engineer resilient power solutions that maintain continuity of supply, protect critical systems and support safe building operation during mains disturbances or outages. These systems underpin business continuity, life‑safety performance and compliance across a wide range of UK building types.
Resilience planning influences early decisions on plant space, acoustic treatment, fuel storage, ventilation, fire strategy and coordination with mechanical and public health services. It also shapes operational strategy, maintenance access and long‑term running cost.
The overview below highlights the essential aspects of resilient power systems and what they mean for the successful planning and delivery of your project.
UPS systems provide instantaneous, short‑duration power to critical loads during mains failure or voltage disturbances. They bridge the gap between loss of supply and generator start‑up, or support sensitive equipment that cannot tolerate interruption.
UPS systems influence plantroom sizing, heat‑load calculations, fire strategy and maintenance access. Battery selection affects footprint, lifecycle cost and replacement strategy. Early identification of critical loads prevents oversizing and ensures realistic resilience planning.
Generators provide extended backup power during prolonged outages or where essential services must remain operational under all conditions. They are commonly required for life‑safety systems, critical infrastructure and buildings with high operational dependency.
Generator design affects structural loading, acoustic performance, fire compartmentation, fuel‑storage compliance and external planning constraints. Early coordination avoids conflicts with air‑intake routes, exhaust discharge, flue routing and noise limits.
Resilient power systems rely on clear separation between essential and non‑essential loads to ensure continuity where required and avoid unnecessary generator capacity.
Clear zoning supports realistic generator sizing, reduces capital cost and ensures compliance with life‑safety requirements.
UPS and generator systems must integrate seamlessly with mechanical, public health, ICT and life‑safety services.
This integration directly affects buildability, programme and long‑term maintainability.
Resilient power systems must meet UK regulatory requirements while supporting efficient operation.
Embedding these considerations early supports compliance, reduces operational carbon and improves long‑term performance.
Resilient power systems require disciplined construction support to ensure safe installation and reliable operation.
A controlled commissioning process is essential for safety, compliance and long‑term resilience.
Our approach ensures power distribution, Our approach ensures resilient power systems are safe, efficient and fully aligned with the wider building services engineering strategy.
