Australians are good at handling heat outdoors. There’s sunscreen, hats and plenty of shade. Indoors, though, workplaces often forget the same rules apply. Sunlight pours through big glass windows, rooms warm up by the hour, and the cooling system struggles to keep pace. Staff feel sluggish, facilities managers field complaints, and energy costs keep climbing. Treating windows like the building’s sun hat makes a real difference. Commercial blinds like bonded roller blinds as well as custom-made commercial curtains block heat at its main entry point, so teams stay cooler, calmer and far more productive.
What heat does to our brains
Heat makes concentration harder. A widely cited review from Lawrence Berkeley National Laboratory pooled data from multiple office studies. It found performance peaked at around 21 to 22°C and dropped about 2% for every degree above 25°C. That doesn’t sound like much until you multiply it across a team of 50 people over a long summer.
Australian research backs this up. A 2015 study published in Nature Climate Change estimated that heat stress cost the Australian economy around US$6.2 billion in 2013 to 2014. Most of that loss came from people working at reduced capacity rather than taking days off. It’s worth noting the study surveyed workers across all industries, not just offices, so office losses alone would likely be lower.
Productivity drops, energy bills rise
When rooms overheat, the usual fix is to turn the air conditioning down. That works, but it costs money. Heating, ventilation and air conditioning (HVAC) typically makes up around 40% of energy use in Australian commercial buildings, according to the federal government’s Commercial Building Baseline Study.
Windows are often the weak spot, responsible for much of the building’s summer heat gain and heat loss in winter. Stop the sun before it hits the glass’s interior surface and the cooling system won’t need to work as hard.
Staff wellbeing matters too
Safe Work Australia’s code of practice for managing the work environment suggests keeping air conditioning between 20 and 26°C, depending on the season and what people are wearing. Uncomfortable heat leads to headaches, fatigue and irritability. It also causes another problem: the thermostat wars. One person’s perfect temperature is another’s arctic blast, and constant tinkering wastes energy.
Glare makes it worse. Staff squinting at screens near a sunny window often move desks, close laptops, or crank the cooling, and none of those helps productivity.
Custom window coverings, not bigger aircons, help solve these issues
This is where well-chosen custom-made commercial blinds earn their keep. They tackle heat, glare and privacy all at once. Here’s what facilities managers and designers should think about:
- Orientation first. North and west-facing windows take the biggest hit in Australian summers, so put the best coverings there.
- Fabric choice. Sunscreen fabrics cut glare while keeping the view. Blockout options suit meeting rooms and screens. Ask suppliers for openness factors and solar reflectance data.
- Light-coloured backings. A reflective or pale outer face sends more heat back outside.
- Finish and durability. Bonded roller blinds, where the fabric is heat-bonded to a backing or edge, resist fraying and look tidy for years in busy spaces.
- Softer spaces. Custom-made commercial curtains add insulation and help with acoustics in boardrooms, hospitality venues and reception areas.
One common mistake is choosing on looks alone. Another is fitting blinds that nobody adjusts. Motorised or automated systems linked to sun sensors can solve that, though they cost more upfront. Suppliers will naturally promote their own products, so ask for independent performance data and compare a few quotes.
Smart, custom-made commercial blinds create cool, productive workplaces
Heat costs Australian workplaces real money in lost focus, higher energy bills and unhappy staff. Shading the windows is one of the simplest, most affordable ways to fight back. Custom commercial blinds tackle glare and heat gain, bonded roller blinds give you a durable, polished finish, and custom-made commercial curtains bring comfort and style to softer spaces. Start with your hottest windows, check the fabric specifications, and pair your coverings with sensible thermostat settings. Your team and your power bill will feel the difference.
