TIP No. 23: “SELF-FUNDING” A RETROFIT CAPEX FOR COMMERCIAL HEALTHCARE & HERITAGE BUILDINGS IS A GOLDEN OPPORTUNITY FOR ARCHITECTURAL ENGINEERING (& ATTRACTING PRIVATE CAPITAL )……………

“Sourcing the Source” AND Thermal Validation is the prime focus for “FIRST SURVEY” to every Commercial Building Retrofit, IF your design is for “SELF-FUNDING” the project. This Source can be interior or exterior to the Building but always delivering a stable, constant (24/7), low grade source of warm calories. Then all Sourced thermal calories are enhanced (by passive or active contribution) for continuous “feeding” to the “Holistic H.P. System: Hot Water” array (either GSHP; ASHP or WSHP).

There is ALWAYS a Source, either architecturally contrived (e.g. interior building waste-fluid sump-tanks; or Trombe & Curtain wall or by Fforde-Chamber passive air & fluids; or stack effect to Canopy Atria etc.) or naturally occurring (e.g. exterior lake, canal, moat, seawater; or below ground etc.).

plement the (24/7) Source input to the multi-H.P. cascade array Primary Loop. Then, H.P. compressors multiply the The contrived “Calorie Harvesting” design must continuously capture & supenhanced constant Heat Source intake to replenish (hydronic: kWh @ set-point), to the over-sized Buffer Storage Tanks. This H.P. intake to Buffer Storage (kWh) Design must continuously exceed the Daily Load Profile distributed downstream (ex Buffer Tanks via Secondary closed-loops,) to the various on-site multi-tasking applications (space heating; moisture control; medical IAQ/IEQ plus). This ultra-Design energy scavenging & harvesting concept also applies to generating “Holistic H.P. System: Chilled Water” for Air-conditioning  Tropical sites. (cf separate TIP).

The “SELF-FUNDING” is generated by the H.P. Array as the “BEATING HEART” of a Hot Water “Holistic H.P. System”. The final “DESIGN” comprises a challenging innovation for a “future-proofing”, site-bespoke, MEP & Ventilation Design…always dependent upon having first thermally validated a “SOURCED – SOURCE”.

Therefore “Sourcing the Source” and Thermal Validation is the prime focus for every “FIRST” Survey for a Commercial Building Retrofit for a Holistic H.P. System……and the Golden Key to attract private capital for “multi-tasking” (higher value-added) Sustainable investment returns.
