Air-conditioning a thermal sieve means paying dearly all summer — every summer, for life. When you build, the order of the works changes everything: what is decided on the plans can never be fixed as well afterwards. With PontBat, every step is entrusted to vetted professionals, at the right moment of the build.

Summer comfort is not bought at the end of the build with a machine: it is built, step by step, starting with what can never be changed again. Here is the sequence that makes the difference under the Tunisian climate.
Before the first shovel hits the ground, the house has already won or lost a large part of its comfort. A carefully studied orientation, overhangs and shading that block the high summer sun but let in the winter one, high-inertia walls that smooth out the swings between day and night, light colours on the roof that reflect the radiation: all of this is decided on the plans — and nowhere else.
Under the Tunisian sun, the roof terrace is what heats up the most: it takes the radiation all day long, and releases it into the bedrooms all night long. So it is insulated first, together with its waterproofing, before treating the most exposed walls and then the glazing. A well-insulated envelope keeps the morning coolness far longer.
At night, the outside air cools the house for free — provided the house knows how to move it: openings designed for natural cross ventilation, from one façade to the other. By day, the logic is reversed: shutters, blinds and solar protections closed on the sunny side to keep the stored coolness in. This play of opening and closing is the oldest air conditioner in the world — and it consumes nothing.
On a house that is already insulated and well ventilated, air conditioning becomes a back-up, not a life raft. A professional sizes it, room by room, based on the actual house — not a random pick off the shelf. Air-conditioning first and insulating later means paying twice: an oversized machine at the start, and energy wasted for life.
None of these mistakes shows at handover. All of them are paid for every summer, on the bill and in comfort.
Integrating insulation, ducts and provisions during construction always costs less than breaking and redoing afterwards. Summer comfort must be written into the specifications, from the plans stage — not into the regrets of the first summer. On PontBat, these requirements go into the project's description before anything is signed.
Electricians and refrigeration specialists of the PontBat network are admitted after a 5-step vetting: business licence, insurance, checked references — and badges that state their level publicly. What makes an installation last is the hand of a professional whose trade is proven, not merely claimed.
Four points to demand in black and white — each with its own safeguard on the platform.
Siting, overhangs and solar protections are not improvised: they are studied on plan, façade by façade. The partner design office integrates them from the design stage — it is their trade, and their signature engages their liability.
“Insulation included” means nothing until it is an explicit line of the specification. On the platform, the standardised bill of works names every line in black and white: what is not in it does not exist — and what is in it will be checked.
Provisions, embedded ducts, unit locations and condensate drains: all of this is planned while the walls are open. The milestone's control point verifies that these provisions exist before the partitions close up.
Openings placed so that air crosses the house from one façade to the other, bedrooms included. It is a plan decision, validated with the design office — and visible in the project documents before the site even starts.
Vetted professionals, a specification that names every line, checks at every milestone: the platform gets things done in the right order, from day one.
