1) Why HVAC Is Needed

Moisture control (critical for conservation), comfort, air quality, fire safety.

2) Challenges in Historic Buildings

Thick walls, high volumes, authentic surfaces, limited service routes, low energy efficiency.

3) Moisture and Climate Control

Relative humidity 45–55% target for museum areas; sensor monitoring, HVAC automation.

4) Concealed Services

Duct and pipe routes through ceiling voids, underfloor, wall cavities; minimum wall penetration.

5) Energy Efficiency

EPC targets apply in adaptive use; heat pump, underfloor heating where suitable.

6) Insulation and Vapour Barrier

Internal insulation; vapour barrier detail critical in breathable buildings.

7) Approval and Execution

HVAC project requires conservation board approval in listed buildings.

8) Conclusion
