PAS2035 - Retrofitting to save the planet

Evidence has shown that significant improvements must be made in the energy efficiency of UK homes if the country is to meet its net-zero carbon goals.

PAS2035 was introduced as the result of the Each Home Counts review to tackle the high level of failure present in domestic retrofit and to determine a better process to tackle energy efficiency in homes.

PAS2035 is the new over-arching and most comprehensive document in the retrofit standards framework and provides a specification for the energy retrofit of domestic buildings and guidance on best practices for domestic retrofit projects.

PAS 2035 is to be used alongside PAS 2030: 2019, which sets out the standards for the installation of energy-efficient measures. From 30th June 2021, compliance with PAS 2035 and PAS 2030 is mandatory for all companies installing Energy Efficiency Measures, including domestic retrofit.

What does PAS 2035 do?

PAS 2035 delivers a whole of house approach to the retrofit process, which takes into consideration the energy efficiency requirements of the entire building from both a technical and occupancy point of view.

A whole-house approach involves identifying areas of improvement in a building and then choosing appropriate measures to make these improvements. Before and after measures have been implemented, a project must be monitored so that energy efficiency improvement can be shown.

Fabric first

A fabric first approach is the most cost-effective method of improvement to building energy efficiency. PAS 2035 states that designers and coordinators of energy-efficient measures must prioritise improvements to the building fabric, for example through better insulation, ventilation, or windows before other measures.

How can Vericon help

When retrofitting in line with PAS2035, you must be able to show the improvement in the energy efficiency of a building due to a project. This is where technology can help.

By installing smart monitors into a building pre-retrofit, and continuing to use them during and post-retrofit, you can see the full improvement in areas such as temperature, humidity, and boiler use. This data can then be used to illustrate the improvement in energy efficiency.

Connected technology can do a lot more than that though!

The Vericon Ecosystem and its ability to remotely monitor and manage assets can be used to:

• Create accurate and validated asset lists by automated asset commission process.

• Remote asset monitoring leading to accurate, complete, and unambiguous information about an asset

• Better awareness of maintenance and operational requirements of an asset.

• Ability to make data-driven decisions regarding the operational and maintenance expenditure based on the actual asset performance and status.

• Real-time measurements of fault, energy performance and preventative failure conditions

• Informed strategic life cycle, end of life and replacement scheduling planning.

• Allow accurate and current health, safety, and risk management policies.

• Drive a pro-active approach to continued maintenance through machine learning-based algorithms, ensuring continued customer welfare and increasing longevity of an asset’s life cycle.
