Passivhaus Retrofit


EnerPHitWhere does Passivhaus fit?

Step-by-step for a whole house approach

What’s going on now (2020)?

Retrofit case studies


Retrofitting existing buildings is undoubtedly a colossal challenge in transitioning the built environment to net zero. Even the majority of new homes built today are not nearly efficient enough, which means we will need to retrofit all 27 million homes, not just the older ones.


这项任务的庞大规模是巨大的。这是2020年和2050年之间每35秒的一个家庭。或者,如果每个改装需要4人6个月,它是500,000个需要200万人的同时改造。

35 seconds to complete each retrofit | 500,000 simultaneous retrofits | 2m people needed in the retrofit industry

It’s also a complex undertaking. Every home is different which means some efficiency measures that work on one project may not be appropriate for another. Get it wrong and you could end up with damp and rot. Getting the right contractor with the right skills and experience is also a worry for most homeowners.

How can we make retrofit happen?

There are many issues surrounding retrofit at scale in the UK. The route to introducing higher standards and theassociated costsare relatively clear for new-build properties. For retrofit, it is much more complex, and several interrelated issues must be addressed:

  • How can we legislate to ensure homes are retrofitted?
  • When should retrofit happen?
  • How far/deep should retrofit go?
  • How should it be financed?
  • How can we ensure retrofits are done to a good standard?
  • 我们如何确保改造不会导致建筑面料损坏?

We know how to safely retrofit buildings and we cannot afford to wait any longer. Read the Trust's recommendations on how to sensibly approach Passivhaus retrofit & assess whether it is right for your building这里. If we had spent all the money raised by quantitative easing in 2007/8 on retrofit, then we would have done it by now…

There were many good ideas in theBonfield Review和the arrival ofPAS2035作为强制性改造要求,将导致更好的标准,并希望能够从房主的更大程度的信任。

Where does Passivhaus fit?

The building physics principles behind Passivhaus apply to any building – but you may not be able to get quite the same results from an existing building where you aren’t really in control of the building’s orientation, structure, shape or amount of glazing. The Passivhaus standard, therefore, includes a retrofit standard called EnerPHit which takes these limitations into account and relaxes some criteria to reflect this. However, it is still a very demanding standard and will typically result in a building that outperforms a new-build property both in terms of energy and comfort. An introduction to the standard can be found on什么是passivhaus.还有一些case studies以下。

一步一步来

一个激进的全房屋改装可能在能量减少和舒适方面实现最佳结果。然而,这是一个重要的事业,可能发生在几年之上。在早期阶段获得序列权和决定对于确保改造的全部潜力是至关重要的,并且该项目并非无意中导致“碳锁定”。因此,Enerphit过程包括以逐步的方式构造改造的工具,从而确保每个步骤的含义被理解并在项目开始时正确地纠正正确。

The Trust's activities

Passivhaus Trust与改造的活动旨在:

  • Support work to examine the technical barriers to retrofit and how they can be overcome
  • Support work to examine how retrofit at-scale can take place in the UK
  • Support work to determine the level/depth of retrofit that is feasible and practical across the range of UK housing stock
  • Lobby central government to introduce legislation to enable retrofit at scale
  • 支持在深度改造中分享最佳实践知识和经验
  • 促进Passivhaus的建筑物理原则,支持改造,并在适当的情况下,Enerphit标准
