Study suggests tool could be used to reduce energy needs for heating and cooling office buildingsEvery year we shift our clocks forward in the spring, and backwards in the autumn. Originally daylight saving was introduced to save energy; reducing the number of hours that the lights had to be on in office buildings. But as climate changes, can daylight saving be used to reduce the energy demand for heating and cooling our office spaces?To answer this question researchers simulated the heating and cooling demands of office buildings for 15 different cities across the United States and analysed the impact that daylight saving could have until the year 2050 under different climate scenarios. Under current climate conditions daylight saving reduced cooling demand by up to 5.9%, but increased heating demand by 4.4%. As we head into a warmer future they found that daylight saving could reduce cooling demand by up to 5.4%, while increasing heating demand by 3.2%. In both cases daylight saving results in a net decrease in energy used. Continue reading...
