Decarbonisation and Energy Efficiency Made Simple

Desired outcome

Identify decarbonisation pathways for Grade 2 listed and extremely energy-inefficient properties by leveraging public portfolio data, artificial intelligence and existing SAP regulations, Lidar, satellite imagery, heat loss imagery, artificial intelligence and any other relevant data. Simulate optimal energy saving solutions for different property types, in a software prototype incorporating a combination of solar power, fabric upgrades, battery storage, energy tariffs, heat pumps, and other energy efficiency measures to achieve sustainability goals. Design a simulation engine that models business and home energy consumption, carbon emissions, creates a clear and linear sustainability roadmap which takes into account budgetary requirements and has a clear timeline for execution and potential savings for different property types based on input data.

Initial Problem Description

The core problem to solve is the challenge of retrofitting Grade 2 listed and highly energy-inefficient properties to meet modern decarbonisation standards. These buildings often come with strict regulatory, structural, and financial constraints, making it difficult to implement conventional energy efficiency measures.

To overcome these barriers, it would be key to address a few key areas. First, energy efficiency in heritage buildings: Grade 2 listed properties are governed by regulations that limit structural alterations, so solutions must respect these restrictions while significantly improving energy performance. Second, many of these buildings suffer from high heat loss due to outdated materials and construction methods. Teams need to simulate effective ways to reduce heat loss, like fabric upgrades, without compromising the building’s heritage value.

The project also requires the development of a simulation engine that accurately models energy consumption and carbon emissions. This tool should propose tailored solutions—solar power, heat pumps, battery storage, and energy tariffs—that offer a clear path to achieving net-zero emissions.

By leveraging data such as Lidar, satellite imagery, heat loss imagery, and AI, create digital twins of various property types. This will help teams assess inefficiencies, simulate upgrades, and explore the impact of energy-saving measures. Budget is also a crucial factor. Solutions need to be financially viable for property owners, so I’m looking for clear ROI calculations, timelines for implementation, and a simulation of energy and cost savings over time.

Finally, the solution needs to cater to different types of properties. Whether it’s a detached home, a terraced house, or a commercial building, the software should provide custom energy efficiency recommendations that reflect the specific challenges of each property type.

Context

This challenge arises within the broader context of decarbonising heritage buildings and extremely energy-inefficient properties, particularly in the face of growing climate goals and sustainability targets. Specifically, it deals with properties that are Grade 2 listed, which means they are of historical or architectural significance and are protected by strict regulations that limit structural changes. These properties are often located in older urban areas or rural settings where energy efficiency standards are far below modern expectations.

The problem exists at the intersection of several factors:

Regulatory Constraints: Heritage buildings face legal restrictions on modifications to their exteriors and interiors, making it difficult to implement common energy-saving measures like double glazing, external insulation, or solar panels.

Outdated Construction Methods: These properties are typically built using older materials that are not energy efficient. Poor insulation, single-glazed windows, and inefficient heating systems result in high heat loss and energy wastage. Retrofitting these buildings while preserving their character poses a unique challenge.

Decarbonisation Goals: With governments setting ambitious targets for net-zero emissions, the pressure to decarbonise all sectors of society, including older buildings, is increasing. This challenge directly supports national and regional sustainability goals by addressing a segment of the building stock that is often overlooked but crucial for meeting climate objectives.

Technological Gaps: Traditional energy-saving methods may not be suitable for these buildings due to their unique characteristics. This is where leveraging advanced technologies like AI, Lidar, satellite imagery, and heat loss imagery comes in. These tools allow for a non-invasive assessment of the building’s energy inefficiencies, creating digital models that can simulate the impact of energy upgrades without physically altering the property.

Financial Considerations: Owners of Grade 2 listed buildings often face budgetary constraints, with retrofitting costs seen as prohibitive. Developing solutions that take into account affordability, with clear return-on-investment (ROI) calculations and potential savings, is crucial for driving adoption of energy-saving measures in this sector.

Custom Solutions for Property Types: The problem is not one-size-fits-all. Different types of heritage buildings—whether residential (terraced houses, detached homes) or commercial—present unique challenges. Any decarbonisation approach must be adaptable to the specific structural and energy consumption characteristics of each building type.

Broader Context:
This problem is part of the global shift towards sustainable development. Retrofitting heritage and inefficient buildings for energy efficiency aligns with both environmental policy and economic sustainability. With rising energy costs and increasing demand for energy-efficient solutions, the challenge of modernising older properties without compromising their historical value becomes ever more pressing. Additionally, urban regeneration efforts often focus on these types of properties, making this challenge critical for future-proofing cities and rural communities while preserving cultural heritage.

Connection to cross-cutting areas

The challenge of retrofitting Grade 2 listed and energy-inefficient properties is closely connected to the areas of Circularity, General Sustainability, Industry 4.0, and Digitalisation in the following ways:

1. Circularity:
The challenge aligns with circular economy principles by promoting the reuse and optimisation of existing buildings rather than demolishing and rebuilding them. Instead of letting heritage properties deteriorate due to inefficiency, this challenge focuses on upgrading and extending the lifespan of these buildings while maintaining their historical value. By incorporating energy-efficient solutions and modern technologies, we reduce the waste associated with demolition and new construction, ultimately minimising the environmental footprint of the built environment.

2. General Sustainability:
At its core, this challenge is about advancing sustainability by improving the energy efficiency and reducing the carbon emissions of heritage and inefficient buildings. It directly contributes to the decarbonisation of the built environment, which is critical for achieving net-zero targets. By enabling property owners to adopt renewable energy sources, efficient heating systems, and smart energy management technologies, this challenge addresses the urgent need for buildings—one of the largest contributors to global carbon emissions—to be part of the sustainability movement.

3. Industry 4.0:
The challenge taps into Industry 4.0 by integrating cutting-edge technologies such as AI, Lidar, satellite imagery, and heat loss mapping to assess, simulate, and recommend energy-saving measures for these properties. The use of digital twins (virtual replicas of buildings) allows us to model and test solutions in a digital environment before implementing them in the real world, improving accuracy and reducing risk. This shift towards data-driven and automated processes is at the heart of Industry 4.0, where smart technologies enhance decision-making and optimise resource use.

4. Digitalisation:
The challenge is firmly rooted in digitalisation as it relies on data analysis, modelling, and simulation tools to solve the complex issue of retrofitting heritage properties. By harnessing digital platforms and algorithms, we can efficiently assess a property’s energy performance, predict the outcome of different interventions, and provide tailored solutions for each building type. Digitalisation enables us to move beyond traditional manual methods and leverage smart software to manage and optimise energy consumption, making it easier for property owners to implement energy-efficient solutions.

Overall Connection:
This challenge spans multiple areas by bringing together sustainability goals, circular economy principles, and the technological advancements of Industry 4.0 and digitalisation. It addresses the pressing need to modernise the built environment while respecting the historical significance of Grade 2 listed buildings, ultimately contributing to a more sustainable, efficient, and circular approach to managing our existing infrastructure.
