众所周知，空调使用量在英国的一些部门S非住宅建筑存量正在迅速增加，并可能接近饱和，但准确可靠的数字很少。同样重要的是要知道这种增长的原因，以及是否有效地采用了能源效率措施来限制空调机组所需的电力。现有的系统主要是为了让客户和员工感到舒适，也为了保存食物的库存，但同样的效果可以用更少的能源消耗来实现，特别是在英国这样的温带气候地区。零售部门的典型能效措施可能包括更有效地使用展示照明，更多和非随意地设置冷却温度，并结合自动关闭的门或空气窗帘。本文提供的结果来自于对英国4个城镇约700家零售店的广泛(低数据深度，但来自大样本)试点调查。人们发现，这是一种非常有效的方式，可以在几天内收集统计上有效的大样本的关键数据，帮助调查与有利的天气相吻合。虽然调查过程基本上是定性的，但也有一些定量抽样。为了评估制冷能源的使用强度，对大约20个零售场所的子样本进行了温度和相对湿度的调查。本文报告的结果表明，在某些情况下，可以将温度设置得更高，以改善热舒适性，并有助于更有效地利用空调设备。本文描述了从试点调查中吸取的教训和后续重大调查的细节，该调查对数千处房屋进行了编号，主要是为了提供纵向数据。到目前为止收集的结果令人担忧，并表明，尽管涉及的能源成本增加，但很少有英国零售店采用任何节能策略来使用空调。
It is known that airconditioning use in some sectors of the UK\'s non-domestic building stock, is increasing rapidly and may be approaching saturation, but exact reliable figures are scarce. It is important also to know the reasons for such an increase and if energy efficiency measures are being used effectively to limit the power required by AC (Air-conditioning) units. Systems exist primarily for the comfort of customers and staff, also for stock preservation in the case of food, but the same effect can be achieved with much less energy use, particularly in temperate climates such as in the UK. Typical energy efficiency measures in the retail sector may include more efficient use of display lighting, more and non-arbitrary setting of cooling temperatures combined with self closing doors or air curtains. The results presented in this paper are from a broad-brush (low data depth, but from a large sample) pilot survey of around 700 retail premises from in 4 UK towns and cities. This was found to be a very effective way of gathering key data for a statistically valid, large sample, in a matter of days, helping surveys to coincide, for example, with favourable weather. Although the surveying process was largely qualitative there was also some quantitative sampling. To assess the intensity of cooling energy use, a sub sample of about 20 retail premises was probed for temperature and relative humidity. The results reported in this paper show that, in some cases, temperatures could be set higher improving thermal comfort and contributing towards a more efficient use of the air conditioning units.Lessons learnt from the pilot survey and details of a follow-on major survey, numbering thousands of premises, primarily in order to provide longitudinal data, are described. The results gathered so far are cause for concern, and show that despite the increased energy costs involved, very few UK retail outlets adopt any strategy of energy saving for air conditioning use.
