Built for legacy assets

How we audit older buildings with care and clarity.

tundra-rhythm focuses on energy performance for buildings that have character, protected elements, or operational constraints. We bridge engineering insight with conservation awareness, so recommendations remain realistic and fundable.

What makes older buildings different

Historic and mid-century structures often have mixed materials, retrofit constraints, and aged plant equipment. Our audits combine fabric inspection, operational interviews, and data monitoring to capture the full picture.

Conservation-aware recommendations. Phased retrofit strategies with cost context. Clear reporting for funding and compliance use.

How we are paid

We are engaged on a fixed-fee basis for each audit package. Optional follow-on services include retrofit planning and monitoring setup, all priced transparently in advance.

“They respected the building’s constraints while still giving us firm, measurable recommendations.”
— Building Manager, York

Our working style

We coordinate with facilities staff to minimise disruption and document every assumption. The deliverables include an executive summary, detailed audit tables, and retrofit pathways with energy and carbon estimates.
