Higher Temperatures

Why Higher Temperatures Matter

Temperatures, particularly in the summer, are projected to rise, posing risks to health and wellbeing and increasing the demand for energy for summer cooling. The Urban Heat Island (UHI) effect, caused when heat is absorbed and then slowly released by hard surfaces, is already observed around the country and is predicted to push urban temperatures even higher. For example analysis suggests that, energy demand for cooling could triple between 2010 and 2050. In addition by the 2050s there may be approximately 4,000 heat-related deaths per year, under a medium emissions scenario.

    Building Cooling and Natural Ventilation

    There are a number of actions and measures which can be taken to cool a building. Increase cooling set points, remove local control where possible and ensure timers are installed and set correctly. Install interlock with heating system to prevent simultaneous heating and cooling. Replace old inefficient equipment. Install controls to switch off cooling if windows are opened. Investigate thin client technology to reduce potential cooling loads. Night time free cooling/natural ventilation.

    Building Fabric to Mitigate Cooling

    The building fabric refers to the ceiling, walls, windows, floors and doors of a building. Optimum design of building fabric can minimise potential cooling requirements, which may lead to the downsizing of cooling systems or sometimes eliminate the need for them at all.

    Chilled Ceilings and Beams

    Chilled ceilings and chilled beams use closed-circuit water-based systems as the heat transfer method. Water is pumped through such a cooling system, absorbing and removing heat from an occupied space as it flows through the system.

    Solar Shading

    The primary function of solar shading is to reduce the thermal heat gain in a building, as well as controlling the levels of direct light.
