Design Direction

# Premium, minimal,
technical, contemporary.

01

The portfolio is designed to sit comfortably alongside international engineering and architectural consultancies rather than alongside environmental campaigning material. Sustainability is communicated through building geometry, technical drawing, simulation output and data, rather than through conventional environmental imagery.

The design does this

- Architecture, façades and building geometry as the primary visual subject
- Custom technical infographics for energy, carbon, daylight and life cycle
- Strong twelve-column grid with generous white space
- Large numerical statistics used as typographic elements
- Restrained colour, with the accent reserved for signal and emphasis
- Diagrams in place of paragraphs wherever a concept can be drawn

And deliberately avoids

- Leaves, trees, wind turbines and green gradients
- Hands holding plants, light bulbs with seedlings, green globes
- Tracked all-capital kicker labels sitting above every headline
- Em dashes in body copy, and two-beat slogan constructions
- Coloured accent bars down the left edge of callout boxes
- Grids of identical rounded cards with a line icon at the top
- Generic stock photography and decoration that carries no information

The palette is taken directly from the logo gradient. There is deliberately no green in the system. That decision separates OKELIS from the visual convention of the sector and follows §8 of the brief.

The graphic device

The möbius triangle from the mark recurs as a structural motif: the LCA loop, as the ecosystem hub, and as a large low-opacity watermark on dark pages.

The framework rail

Certify → Measure → Optimize → Decarbonize runs along the foot of every service page with the active stages lit, giving the document a spine.

Extensibility

The same tokens, grid and components carry directly into proposals, presentations, social graphics and the OKELIS website.

Text face

OKELIS integrates sustainability certification, ESG, carbon accounting and advanced building-performance analysis. Body copy is set at 9.1 pt on a 1.58 line height for comfortable reading at A4, with headings tracked tightly for a contemporary, engineered feel.

Why this typeface

SF Pro is Apple's system typeface, a contemporary neo-grotesque with exceptionally clean numerals and a wide optical-size range. It reads as modern and engineered rather than corporate or generic, and it holds up at both 6 pt caption and 40 pt display.

Two optical variants are used: SF Pro Display for headings, numerals and short labels; SF Pro Text for body copy, where its wider spacing and taller apertures improve legibility at small sizes.

Section labels are set in sentence case with no added tracking, marked by a short accent rule. The wide-tracked capital kicker above a headline, and the coloured left border on callouts, have both been designed out.

Page geometry

Format | A4 portrait, 210 × 297 mm
Margins | 16 mm sides · 15 mm head · 14 mm foot
Grid | 12 columns · 4 mm gutter

Twelve-column grid

Standard layouts use 6 + 6, 7 + 5, 5 + 7 and 4 + 4 + 4 divisions. Statistics and icon sets run on 3 + 3 + 3 + 3.

The system is built on tokens, so an alternative licensed typeface can be substituted without redrawing any layout. Four pairings can be compared live in the review link.

Proposed Structure

# Twenty-eight pages.

03

The structure follows §5 of the brief. Each core service occupies a two-page spread: an opener carrying the proposition, scope and headline infographic, and a second page carrying method and deliverables.

Opening
01 Cover Logo, façade graphic, brand statement, framework rail
02 About OKELIS Introduction, philosophy, core message, credentials
03 Vision & Mission Purpose, vision, mission, values
04 Why OKELIS Six differentiators, AI-assisted approach, client value
05 Sustainability Ecosystem Single infographic connecting all six disciplines
Core services
06–07 A · Green Building Certification Rating systems, lifecycle rail, credit method
08–09 B · ESG Reporting & Advisory E/S/G pillars, dashboard, frameworks, methodology
10–11 C · GHG & Carbon Accounting Scope waterfall, three scopes, reduction hierarchy
12–13 D · Life Cycle Assessment & EPD Hotspot analysis, EN 15978 life cycle loop
14–15 E · Life Cycle Costing Whole-life cost split, crossover curves, method
16–17 F · Building Energy Modelling Baseline vs proposed, end-use split, ECM matrix
18–19 G · Daylighting Assessment Floor-plate heat map, section study, façade variables
Integration & evidence
20 Integrated Approach Service × project-stage matrix, service interactions
21 Project Lifecycle Concept → Operation, influence vs cost of change
22 Sectors We Serve Ten custom sector icons with sector-specific issues
23 Standards & Frameworks Rating systems, carbon, ESG, energy and comfort standards
24 Project Experience Register of the 25 Estidama projects, scope and rating per entry
25 Case Study template Reusable one-page project template
Closing
26 Our Approach Six-step engagement methodology
27 Why Work With OKELIS Value by audience, closing statement
28 Contact / Back cover Contact block, framework rail
Page rhythm

Dark navy pages carry the service openers, vision, lifecycle and contact; tinted and white pages carry the detail. The alternation separates each service spread from the next.

Extent

28 pages, within the 20–28 range set by the brief. The case-study pages can be removed for a shorter capability version without redesign.

Proposed Structure 04
Infographic Programme

# Every technical concept
drawn, not described.

04

All infographics are custom-drawn vector, built on the brand palette and typeface. None are stock or templated. Every figure in the draft carries illustrative data. Final figures will be replaced with OKELIS project values on issue.

01 · PAGE 05
Sustainability Ecosystem

Six disciplines orbiting a single outcome, with integration chords showing how each informs the others.

02 · PAGE 10
Carbon Accounting

Scope 1 + 2 + 3 waterfall to corporate footprint, then reduction, residual and net zero.

03 · PAGE 13
Life Cycle Thinking

EN 15978 cradle-to-grave loop with the Module D circularity return arc.

04 · PAGES 14–15
Whole-Life Cost

Cost composition bar plus the crossover curve showing where low capex stops being cheaper.

05 · PAGES 16–17
Building Performance

Baseline versus proposed end-use stack, end-use donut, and the inputs → simulation → outputs model.

06 · PAGE 18
Daylight Analysis

Floor-plate autonomy heat map and a section study showing shading, penetration and falloff.

07 · PAGE 08
ESG Dashboard

Emissions intensity trend against target, with operational KPI bars.

08 · PAGE 20
Integration Matrix

Service against project stage, showing where each discipline holds most influence.

09 · PAGE 22
Sector Icon Set

Ten custom line icons drawn on a single 48 × 48 grid with a consistent stroke grammar.

Case study template

Two reusable formats are provided: a full page and a two-per-page compact variant. Both carry project name, location, building type, area, client, services, certification target, challenge, solution and a four-metric results band.

Data and imagery required from OKELIS

Project photography, simulation screen captures from IES and eQuest, real project metrics, final contact details and the registered address. All figures in this draft are placeholders.
