Austria expands heat‑protection services and backs external shading measures

Caritas in Graz has set up “climate oases” for residents in precarious housing, offering a guide to cool spots, drinking fountains and heat‑relief packs that include sunglasses, caps, water bottles, sunscreen and insect repellent. Open facilities such as a climate‑controlled railway mission, the Mesnergasse day centre and the Arche 38 night shelter provide shade, chilled drinks and shower access during the hottest hours.

At the policy level, Austrian officials are reviewing ways to make climate‑friendly upgrades easier in rented and owned homes, and Vienna will permit air‑conditioning units in municipal housing. Industry groups argue that external sun‑shading – roller shutters, blinds and textile screens – is a highly effective, low‑energy solution. Simulations suggest such systems can cut indoor temperatures by up to 3.2 °C, lower cooling energy demand by up to 71 % and, over a year, reduce overall energy use by up to 40 %, including heating savings. The city of Vienna is offering subsidies of up to 50 % for external shading installations, though owners still face approval hurdles. “External sun‑shading is under‑appreciated in the current heat‑protection debate,” said Markus Szotrell, managing director of the Austrian Sun‑Protection Association.
