过热和部分O

近年来，许多新房屋中的风险增加了，这通常是隔热性和改善气温改善的意想不到的结果。这导致了许多研究，最著名的是来自DCLG，NHBC基金会和零碳枢纽，所有这些研究都强调了增强的织物性能是一个重大原因。虽然在暖气季节更具隔热性是有利的，但在夏季，它也可能会使不需要的热量捕获不需要的热量。通风不良也导致了问题，导致家庭内部和外部经历的温度之间的分离日益增加。

单一的角度公寓and apartments are identified as being at particular risk of overheating, especially in city locations where delivering effective ventilation can be challenging. Alongside reduced fabric heat loss, there is a range of other aggravating factors that can come together to cause overheating. Guidance on tackling overheating identifies the provision of adequate ventilation and shading as being the most effective design measures to apply. Other techniques are also identified including the use of thermal mass with night cooling, which offers a further means of helping to control overheating.

设计策略摘要

• Limiting solar gains– Apply design measures that limit solar gain, which can include external shading, solar control glass and optimising the orientation and glazing area.
• Remove excess heat– Provide openings for adequate ventilation, ideally located on opposite facades to promote cross flow. Night ventilation is very effective at removing heat from the fabric and works particularly well in dwellings with亚搏娱乐网站。
• Absorb- 使用混凝土和砌体亚搏娱乐网站住宅中提供的热质量在白天吸收建筑物内部的多余热量，然后使用夜间通风将其清除。以这种方式使用热质量可亚搏娱乐网站以将峰值内部温度降低几个度。
• Provide information- 确保为建筑物所有者提供有关符合O部分的规定以及应采取系统操作以防止过热的方式的足够信息。
