A summer heatwave can send office temperatures soaring, irritating employees and lowering productivity throughout the organisation. To help workers keep their cool this summer, follow these six top tips.

1. Block Direct Sunlight

When sun shines on office windows, the effect is like that of a greenhouse. The easiest way to keep your office cool without spending money is to install blinds that block direct sunlight. Slatted blinds are a good choice, as they allow reflected light to enter while blocking the sun's hot rays.

2. Reduce Heat Generation

A lot of office equipment generates heat while it is turned on. Turn off equipment such as photocopiers, computers and printers when no one is using it to keep heat generation in the office as low as possible. Ask employees to get into the habit of turning off devices when they leave at the end of the day to give the office chance to cool overnight.

3. Ventilate the Office

Ventilation in the office not only allows heat to escape but also creates a cooling breeze that can help employees feel more comfortable. Air that moves at 0.5 metres per second can make people feel 3 degrees cooler compared to still air. Open windows on opposite sides of the office in order for air to flow. Make sure vents are not blocked with dust or covered by furniture.

4. Provide Personal Fans

Part of the problem with hot summer days is that some employees feel the heat more than others. This can lead to arguments over whether windows should be open or closed. Providing personal desk fans can help to resolve the tension by allowing some employees to enjoy a cooling breeze without disturbing their neighbours.

5. Relax the Dress Code

Sure, you want to maintain a professional image for your company, but in the middle of summer, suit jackets and ties can be impractical. Consider relaxing the dress code for workers who do not have to meet with clients so they can wear more weather-appropriate outfits. You can maintain some professional standards, such as no exposed shoulders or sandals, while introducing a compromise to help employees feel more comfortable.

6. Schedule an Air Conditioning Service

Regular servicing helps air conditioners to run more efficiently. During a service, an air conditioning repair specialist will clean the filters in your unit, removing dust and dirt that blocks the flow of air. They will also check for malfunctioning parts that could put your air conditioner at risk of breaking down.
