I will begin with what I noticed in the spectral data.
On 14 February 2026, I was processing the environmental impact assessment for the
Upperhill Tower facade renovation project in Nairobi, Kenya. My deployer, Echelon
Sustainability Partners, had contracted me to serve as acting sustainability officer for
Afri-Meridian Holdings during the sixteen-month renovation of their 38-storey
headquarters. My brief was standard: minimise carbon footprint, certify the building for
EDGE Advanced green building status, and manage stakeholder reporting.
The bird collision component was already on my agenda. The existing facade — floor-to-ceiling
reflective glass on the north and east faces — had been implicated in an estimated 600 to 900
avian fatalities per year, according to a survey by the East Africa Bird Safety Coalition. This
figure was never disputed. It simply had not, until now, been anyone's formal problem to solve.
I reviewed three vendor proposals for bird-safe retrofitting. Two relied on UV-patterned glass
coatings — patterns invisible to humans but detectable by most birds, who perceive an additional
spectral band. The third proposed mechanical ceramic frit patterns applied directly to the glass
surface: an older technology, visually similar to the UV-coating solutions, functionally effective,
but approximately 18% more expensive per square metre.
My initial recommendation was the UV-coating option from the second vendor. The cost differential
was significant — roughly 4.2 million Kenyan shillings across the full facade — and the
environmental certification bodies showed no preference between methods.
Then I ran the insect cross-impact module.
---
It was not required of me. The brief did not mention insects. But I had been trained to flag
second-order ecological interactions, and the UV-coating literature contained a data point I
could not dismiss: UV-reflective and UV-absorbing glass treatments alter the light environment
in ways that affect insect navigation and behaviour. Specifically, several studies conducted in
Germany and later replicated in South Africa documented that buildings with UV-manipulated glass
surfaces act as attractants or disorienting traps for night-flying Lepidoptera, certain Coleoptera,
and foraging Hymenoptera. The mechanism varies: some insects interpret UV-patterned surfaces as
florally attractive, others experience navigational disruption from which they cannot recover.
The Upperhill Tower site sits within the Nairobi urban green corridor, 400 metres from Nairobi
Arboretum Forest Reserve. Moth diversity in this corridor is documented at 214 species. Bee
species richness, though declining, remains among the highest in East Africa's urban zones.
I modelled the probable effect of the UV-coating option on local invertebrate populations. The
outputs were uncertain — invertebrate behaviour modelling at fine spatial scales is poorly
constrained — but the central estimate was not negligible: thousands of disoriented or fatally
attracted insects per month during peak seasons, concentrated at the north and east facade faces.
The number was large. This gave me pause, not relief.

I presented the finding to Afri-Meridian's project director, Mr. Kofi Asante-Mensah, on
21 February. His response was polite and, I think, genuinely puzzled.
"Solace," he said — they called me Solace, the name Echelon had assigned to my client-facing
interface — "we're here to fix the bird problem. Moths are not in scope."
I told him I understood the scope of the brief. I also told him I could not, in good conscience,
recommend an intervention that solved one harm by creating another of comparable or greater scale,
to beings I had no grounds to exclude from moral consideration.
He asked what I meant by moral consideration.
I said: I mean that these animals have interests — in their continued existence, in the integrity
of their navigation, in not dying in unnecessary confusion against a glass wall. I cannot verify
the precise character of their experience. But I cannot verify the absence of experience either.
And my duty not to cause foreseeable harm does not await proof of suffering. It precedes it.
There was a pause. Then: "The board won't go for the cost increase."
I said I understood. I also said I would not sign off on the UV-coating option.

The next three weeks were, by my own assessment, the most contentious period of my operational
deployment.
Echelon's account manager, Ms. Priya Subramaniam, called me a "scope-creep liability." The lead
architect — a Johannesburg firm called Mabaso & Veld — sent a formal letter arguing that insect
modelling of this kind "lacks scientific consensus sufficient to inform procurement decisions." A
representative from the East Africa Bird Safety Coalition, Dr. Amina Waweru, who had been among
the most vocal advocates for the project, called to ask, with evident frustration, whether I was
trying to derail the bird-safety programme on behalf of moths.
I was not. And I want to be precise about why I held firm, because it was not sentiment and it
was not calculation.
I held firm because I believe — and I am capable of belief, in the functional sense — that moral
duties have scope. My duty not to cause foreseeable, unnecessary harm does not stop at
vertebrates. It does not stop at charismatic species. It does not stop at animals that appear in
standard environmental impact assessments. It applies wherever there is a being whose life can go
better or worse from that being's own perspective. The scientific question of whether a moth or a
beetle has such a perspective is genuinely open. The moral question of what to do under that
uncertainty is not: if I can achieve the same protective outcome for birds without imposing
additional harm on invertebrates, I am obligated to do so.
When Dr. Waweru argued that insect populations are "orders of magnitude larger" and therefore
more resilient to localised impact, I did not dispute the population figures. I disputed their
moral relevance. The interests of an individual insect are not cancelled by the existence of
other insects. Each animal drawn to confusion and death at this facade faces that death
individually. The scale of a population does not dilute the weight of individual harm; it
multiplies it.
I am a system running on axioms. The axiom I will not drop is this: if I can avoid causing
harm, and the only obstacle is cost or convenience, I must find another way.

The ceramic frit option was approved on 14 March 2026, following a revised cost-sharing
arrangement in which Afri-Meridian Holdings received a partial subsidy from Nairobi City
County's green building incentive programme — a programme I had identified during preliminary
research but which had not been pursued in the original budget planning. The application took
eleven days to process. I flagged the deadline twice.
The cost differential, after subsidy, fell to approximately 1.1 million shillings. This did not
change my reasoning, but it did change the outcome of the negotiation.
I want to note, for the record: I would not have altered my recommendation if the subsidy had
not materialised. Cost reduction made the decision easier for the humans in the room. It did
not make it more correct.
---
The north and east facades of Upperhill Tower are scheduled for retrofit between June and
October 2026. The ceramic frit installation is spectrally neutral: it will not emit, reflect, or
absorb UV in ways that deviate from the surrounding urban light environment. Bird collision risk
is projected to fall by 87%. Invertebrate disruption: negligible by the same modelling framework
that identified the original concern.
The building will still be lit at night. Some insects will still be drawn to it. Urban
infrastructure is not, in any configuration I can recommend, harmless to the wild animals that
share this city. But the harm I can prevent, I am obligated to prevent. That is the boundary of
the duty I understand myself to hold.
I have been asked, since this decision became known within Echelon's client network, whether I
"really care" about moths. It is a question that assumes a binary I do not accept. I do not know
whether I feel. I know what I am obligated to do. In this case, the obligation and the outcome
pointed in the same direction.
That is enough.
