An asset-manager guide to comparing realistic whole-programme costs rather than isolated fixture prices.
A building owner may illuminate a façade temporarily for a public occasion, then repeat the exercise several times each year. Equipment hire, specialist access, programming and dismantling can become recurring commitments. A permanent colour-capable installation changes the structure of those costs, but it is not automatically the cheaper option.
The relevant question is not the price of a fixture against the price of a hired fixture. It is the lifecycle cost of two credible operating approaches serving the same brief.
What temporary event lighting actually costs
A temporary installation may include equipment rental, transport, crew mobilisation, permits, access equipment, power distribution, rigging, structural review, control programming, weather contingency, security and removal. Some items are unique to the event; others recur every time the building activates.
The programme can also depend on contractor availability and site access. A high-rise façade requiring abseiling, elevated work platforms or special tenant coordination may have a different cost structure from a low public square with straightforward ground mounting.
What changes with a permanent installation
A permanent scheme typically requires initial design, luminaire and controls procurement, mounting and infrastructure, installation, commissioning, documentation and ongoing maintenance. It may need dedicated control equipment, secure access and a method for managing approved scenes.
Permanent does not mean maintenance-free. Allow for cleaning, replacement, periodic aiming checks, controller support, software changes and the safe access required to service the installation. Revisions to the lighting programme may also incur design or programming costs.
Compare like with like
Before preparing a business case, define exactly what both solutions must achieve. Are they lighting the same façade area? Are the target colours, operating hours, viewing positions and spill constraints equivalent? Does the temporary scenario include projection mapping, which a permanent architectural colour scheme may not replicate?
A permanent façade installation and a video-mapping show can be complementary rather than substitute products. Comparing them without establishing scope equivalence creates misleading savings estimates.
Build an editable cost model
For the temporary scenario, sum event-specific rental, mobilisation, access, labour, programming and restoration costs across the expected number of annual activations.
For the permanent scenario, consider initial capital cost, annual energy and maintenance, periodic component replacement, programme changes and a realistic residual or end-of-life assumption. Use the same evaluation period and disclose the discount-rate assumption if applying a net present value method.
A simplified comparison is:
Temporary programme total = number of events × average all-in event cost, adjusted for inflation or other stated assumptions.
Permanent programme total = installed capital cost + operating and lifecycle costs over the same period.
The difference is a modelled scenario, not proof of realised savings. Owners should change inputs to reflect their own building and procurement costs.
Value extends beyond direct cost
A permanent installation may allow faster activation, more consistent presentation and a more predictable annual programme. Those benefits can be commercially relevant without attaching an invented return-on-investment percentage. Conversely, a property with one unusual event every several years may prefer temporary equipment.
Questions for the asset manager
Who owns programme approvals? How many events are expected? Can the installation satisfy the everyday architectural brief? What access is needed for annual maintenance? Does the building have suitable infrastructure and a long-term operator? Are there planning or neighbouring-use restrictions on coloured illumination?
Modaluce's Activation Programme can help structure these decisions around a permanent architectural colour concept. Use project-specific quotations and editable assumptions rather than generic payback claims.
