Defeating Heat on the Ground: Reclaiming Hot Cities Through Climate-Responsive Architecture

I was born into the arms of mountains. Not metaphorically — literally. My first sights were evergreen conifers standing shoulder to shoulder up impossible slopes, and broad-leaved deciduous trees turning gold and rust in a season Lahore has never known. My village sat high in the hills of Murree, and our house was wrapped in thick blue pines, its stone walls climbed over by a creeper we call, locally, Chinar bail. I am sixty-two years old now. Those creepers are still there. My family has never once painted the outside of that house, because the house was never bare — it was always wearing something green.

We had a sloped roof of corrugated sheets and two verandas. From one, I could see the warm, familiar slopes of Patriata Peak, close enough to feel like a neighbor. From the other, I could see all the way to the distant, majestic crown of Apharwat Peak, standing in the Pir Panjal range (in the Indian-held Kashmir) like something that had always been there and always would be. Before I could walk steadily, before I understood anything about the world at all, those white giants were already watching over me. I did not choose them. They chose me first.

Then, when I was in grade five, my family moved to Lahore. I remember the heat the way you remember an insult. Lahore’s air sat differently on the skin — heavier, drier, unrelenting in a way the mountain air had never been. Every night for years afterward, I carried the cool, moist air of Murree into my dreams and set it down over that city, as if wishing hard enough might actually change a climate. It never did, of course. Dreams don’t lower temperatures. But they do something almost as important — they tell you, quietly and persistently, what your life is going to be about. Mine has been a sixty-two-year-old argument with heat, waged on behalf of a boy who never stopped missing his mountains.

I am not a botanist. I am an engineer by training and by education — a person who wants to know how things work so he can make them work better. But growing up with a conifer forest on two sides of my house and an orchard of apples, apricots, peaches, cherries, and pears on the others, you cannot help but start listening to plants, even without a botanist’s vocabulary for what you’re hearing. When wind moves through a conifer forest, it makes a very particular sound — psithurism, it’s called — a low, steady hiss, almost a drone, sometimes rising into something like a rushing roar. I have never fully understood what that sound was telling me. I still don’t, even now. But something in it reached me anyway, some wordless insistence that these were not just standing timber but living things with a stake in their own survival. That feeling has never left. It is, I think, the real reason I have spent my life defending forests rather than simply studying them.

It’s also why, years later, I could not stay silent when nearly 60,000 kanals of ancient conifer forest on Patriata Mountain — the very peak I used to watch from my veranda as a boy — came under threat. That fight, and the fact that the forest still stands, remains one of the environmental victories this country can point to. I don’t say that with pride so much as relief. Some things, once gone, do not come back on any human timescale.

Working on this “most critical subject” for decades has taught me something the seminars never say out loud: climate change is not defeated in a conference hall. It is defeated, if it is defeated at all, on a mountainside with a shovel in your hand, in a district office arguing over a land-use file, in a courtroom fighting a construction mafia that wants a forest turned into plots. I have stood in front of bulldozers meant for Patriata’s conifers. I have walked ridgelines counting trees that existed only because someone, at some point, refused to sign a piece of paper. That is what practical work on this crisis actually looks like. It is slow, unglamorous, and it rarely photographs well.

Which brings me to the part of this story that I find hardest to tell, because it is not a story about mountains anymore. It is a story about grief of a different kind.

Over these same decades, I have watched an entire industry grow up around the word “climate change” in this country, and I say industry deliberately, because that is what it has become. I have sat in enough audiences to know the pattern by now: a five-star hotel ballroom, a banner with a green leaf on it, a foreign donor’s logo beside a local one, a buffet lunch that likely cost more than the annual budget of the village project it claims to represent. A “landmark report” is launched with great ceremony. Photographs are taken. Certificates are handed out. And then everyone disperses — to the next conference, often in another country, then another, then another — while the glacier keeps retreating and the city keeps heating and the air keeps failing every WHO standard we claim to be chasing. I have asked, more times than I can count, the only question that matters: what, physically, on the ground, has changed because of this? How many tonnes of greenhouse gas were actually kept out of the atmosphere? How many trees are standing today that would not otherwise be standing? Too often, there is no answer, because there was never a project designed to produce one — only a report designed to be launched.

I say this with real sorrow, not satisfaction, because I know how much damage it does. Every rupee spent on a conference banner is a rupee not spent on retrofitting a school roof or planting a windbreak or auditing a building’s energy use. Every career built on attending climate events rather than reducing climate impact is a career that quietly convinces a funder, a minister, or a young engineer that this problem is being handled, when it is not. I have watched colleagues walk into this work as believers and walk out of it, years later, transformed — not by the mountains, but by proximity to money that moves in the name of a crisis it does very little to solve. That is the tragedy underneath the tragedy: a genuine, existential threat to this country has been allowed to become, for a certain class of organization, a business model. Fortunes have been made. Foundations have been laid for very few buildings, and rather more for careers.

This is why I believe, without hesitation, that the time has come for a performance audit of climate NGOs in Pakistan — not a financial audit alone, which only asks where the money went, but a performance audit, which asks the harder question: what did the money achieve? Every organization that has received climate financing, whether from an international donor or the state, should be required to show, in verifiable, measurable terms, the greenhouse gas emissions it actually reduced, the trees it actually planted and kept alive for five years and ten, the buildings it actually retrofitted, the people whose air actually got cleaner. Not narratives. Not glossy reports with a foreword from a dignitary. Numbers, monitored independently, published openly, and compared honestly against the budget spent to produce them. Any organization that cannot show this — after years, sometimes decades, of grants — should not be trusted with another rupee of climate money, however well-connected its board or however polished its next report will be. This is not a radical demand. It is the least the atmosphere is owed.

Nearly fifty-eight years into this life, I believe I have finally found something close to a recipe — a workable answer to a question that has followed me since that first hot Lahore summer: how do you cool a city down? Not with wishing, this time, but with design. Green buildings, built properly, are not decoration. They are climate machines disguised as architecture — smart insulation and efficient systems that cut the energy a building needs in the first place; low-flow plumbing and rainwater harvesting that treat water as the finite thing it is; recycled and rapidly renewable materials like mass timber instead of carbon-heavy concrete and steel; ventilation and finishes that protect the lungs of the people living inside. Done at any real scale, these buildings do something a lone wish never could — they pull down a city’s average temperature and push its air quality toward what the World Health Organization actually recommends, not just what we’ve learned to tolerate. The technology and the financing both exist now. What has been missing is the will.

And that, I think, is the honest ending to this story. The larger challenge was never really technical — it was always going to be persuasion. Educating civic authorities, architects, and engineers to build this way as a default, not an exception, is hard enough. Harder still is convincing a climate establishment, at home and abroad, that has grown comfortable inside five-star ballrooms to instead measure itself by tonnes of carbon kept out of the sky and degrees of heat kept out of our cities. Hardest of all, perhaps, is asking that establishment to submit to the same scrutiny it demands of everyone else — a real performance audit, not another report. I carried cool mountain air into a hot city in my dreams as a child, and I have spent fifty-eight years trying to make that dream something other than a dream. I would like, before I am done, to see it carried there for real — not launched at a hotel, but built, brick and tree and rooftop, into the bones of the city itself.
