As temperatures across Greater Manchester are forecast to soar this week, an expert from the University of Salford has shared practical advice on how residents can keep their homes cool and stay comfortable during the hot spell.
Professor Lubo Jankovic, Professor of Energy and Buildings at the University of Salford, has been researching overheating in homes using the university’s state-of-the-art Energy House 2.0 facility. The unique climate chamber can recreate weather conditions ranging from -20°C to +40°C, as well as simulating wind, rain, snow and sunlight, allowing researchers to study how homes perform in extreme temperatures.
Professor Jankovic’s top tips for keeping your home cool include:
• Keep windows open while outdoor temperatures remain lower than indoor temperatures, particularly overnight, to allow excess heat to escape. As temperatures rise during the day, close windows to prevent hot air entering the home.
• Create cross-ventilation by opening windows on opposite sides of the house when conditions allow. Opening windows on different floors can also help encourage air circulation through a natural “chimney effect”.
• Close blinds, curtains or shutters during the hottest parts of the day to reduce heat from direct sunlight. If using louvre blinds, angle the blades downwards to better block the sun’s rays.
• Once windows are closed, use electric fans to improve air movement indoors and help occupants feel cooler.
• Move around the home to take advantage of cooler areas. North-facing rooms are often cooler than south-facing rooms, while ground floor spaces typically remain cooler than upstairs rooms or converted lofts.
• Wear lightweight summer clothing and avoid strenuous activities during the hottest periods of the day.
• Stay hydrated and keep your skin damp where possible, as evaporation helps the body regulate temperature.
• Homeowners with heat pumps may wish to speak with their installer about whether cooling functions are available. However, Professor Jankovic notes that converting a heating system for regular cooling use may require significant modifications and should only be undertaken with professional advice.
Professor Jankovic said that simple measures such as managing ventilation carefully and blocking direct sunlight can make a significant difference in maintaining comfortable indoor temperatures during periods of extreme heat.
