Ibrahim Saad writing as Saad da Alex

He measures how much of a tower actually works. He writes about what cannot be measured at all.

Dr. Eng. Ibrahim Saad is an Egyptian architect, engineer and researcher with more than thirty years of design leadership across the Middle East. As Saad da Alex, he writes philosophical fiction about memory, perception and the order hidden in noise.

Architecture and research, two titles

Every square metre lost to inefficient design becomes an energy penalty the building pays for fifty years.

Both books grow from the same research: 34 case buildings, 20 expert interviews, and real projects tracked through five design stages in the UAE and Saudi Arabia. The result is the ASEF-S framework, a GCC-calibrated way to see the energy cost of a spatial decision while it is still cheap to change.

Architectural Space EfficiencyFrom Feasibility to Sustainability

Dr. Eng. Ibrahim Saad (Dr. Saad da Alex)

The first practitioner guide to quantify what lost net-to-gross area costs, why UAE and KSA high-rise construction amplifies the effect, and what to do about it at every design stage.

Across the Gulf, buildings lose significant floor area between concept and completion, and the region's climate turns that lost efficiency into an outsized energy and cost burden. Built on a research base spanning 34 international case buildings, expert interviews and longitudinal tracking of real projects, the book translates the evidence into the ASEF-S Framework: a scoring and evaluation system architects, developers and sustainability consultants can apply from concept sketch through authority submission. Written for working professionals rather than academic audiences, it is meant to sit on a desk and be used.

What's inside
  • The quantified relationship between net-to-gross ratio and annual building energy performance, in real cost and carbon terms
  • Why UAE and KSA high-rise buildings show a measurably larger efficiency penalty than global benchmarks
  • A stage-by-stage breakdown of where space efficiency is typically lost, and how to stop it
  • The ASEF-S Design Evaluation Tool in three ready-to-use formats: concept, schematic/developed design, and authority submission
  • Role-specific action checklists for architects, developers and regulators
  • Worked examples and typology-specific benchmarks for GCC high-rise practice

The Net-to-Gross EquationArchitectural Space Efficiency and Energy Performance in High-Rise Towers

Dr. Eng. Ibrahim Saad (Saad da Alex)

Every high-rise carries a hidden number few developers ever ask about: how much of its floor area actually does anything, and what the rest is quietly costing in energy, every year, for the life of the building.

This book proves what practitioners have long suspected but never measured: spatial efficiency is not a leasing metric with a side effect on sustainability. It is one of the most powerful, controllable levers on a building's lifetime energy performance. In hot, arid, high-density markets, each percentage point of net-to-gross ratio lost is associated with a 10.43 kWh/m²/year increase in energy intensity, 46% steeper than the equivalent effect in temperate-climate buildings.

Who it is for

It delivers the ASEF-S framework, a regionally calibrated, three-dimensional assessment tool with an Energy Consequence Calculator that lets architects and developers see the energy cost of a spatial decision at concept stage, before it is locked in for forty years.

Written for architects defending design decisions in review, developers underwriting feasibility, sustainability consultants bridging regional and international certification systems, and researchers extending the methodology.

The HarmonionsDissonance to Harmony

Saad da Alex (Dr. Ibrahim Saad)

Seven philosophical, often uncanny meditations, each one on the surface a psychological mystery, the last of them a four-movement novelette.

We are born believing in a vantage point outside the world, a place from which the self can watch, weigh and remain untouched. The Harmonions is written against that belief. To look closely at anything is to enter into a relationship with it, and every relationship runs both ways. The pattern you trace begins to trace you. The memory you examine begins to edit its examiner.

On the title

A Harmonion is neither a musician nor a listener; it is what a person becomes at the point where the two can no longer be told apart, the one for whom dissonance has ceased to be a threat and become a language. In the closing novelette it is also a unit of measure: the smallest interval within which a sound and the world can agree.

In music, dissonance is not disorder but tension that has not yet found its resolution. The collection does not dissolve the strange by explaining it. It moves the reader, story by story, from resistance to attention, from the desire to control what is seen to the more difficult discipline of listening to it. Some tensions resolve. Others are deliberately left open, because a sustained note can be truer than a cadence forced shut.

Written in English and rooted in the contemplative tradition of Arabic philosophical fiction, The Harmonions speaks to readers who suspect that the deepest questions are not those we ask, but those that have been quietly asking us.

About the author

One person, two kinds of attention.

Dr. Ibrahim Saad is an Egyptian architect, engineer, researcher and author. With more than thirty years of experience in architectural design leadership and multidisciplinary project delivery, he has contributed to major mixed-use, residential, commercial, hospitality, healthcare, educational, cultural, governmental and sports developments across the Middle East.

He holds a PhD, an MBA, and a Bachelor of Science in Architecture from Alexandria University. His architectural and academic writing explores space efficiency, design performance, urban memory, and the relationship between measurable systems and human experience.

As Saad da Alex, he explores memory, identity, perception, consciousness, music, space, and the unseen relationships connecting people, places and ideas. The name Saad da Alex is a nod to Alexandria, in the manner of da Vinci.
