Navigating Residential Upgrades: A Holistic Approach

When it comes to upgrading residential properties — from improving insulation to swapping out heating systems or installing solar panels — the temptation is often to tackle one improvement at a time. But upgrades made in isolation can lead to inefficiencies, added costs, or even unintended consequences affecting comfort, durability, and occupant health.

At SEES, we take a different view: Think holistically. Plan thoroughly. Execute with purpose.

Why a Holistic Approach Matters

Upgrading the fabric of a building without considering ventilation or heating loads can cause condensation issues. Installing a heat pump without addressing insulation or hot water demand might leave occupants cold — and bills high. Even well-intentioned green tech can underperform if it’s not properly integrated.

That’s why we’ve created a comprehensive guide for navigating residential upgrades — whether you’re planning a single intervention or a full retrofit.

What’s Inside the Guide?

We break down common pitfalls, essential technical considerations, and best practices based on current SAP conventions — from the planning stage right through to handover.

Inside you’ll find practical insights on:

• Fabric Improvements: Understand the impact of different upgrade measures, how to prioritise them, and avoid creating thermal bridges or ventilation issues.
• Heating System Selection: Choose systems that complement the fabric and layout of your home — and avoid costly compatibility oversights.
• Renewable Integration: Learn how to incorporate solar PV, heat pumps, and other technologies in a way that works harmoniously with the building design.
• Assessment Methods: Explore how SAP, PHPP and dynamic simulation can support decision-making and performance predictions.
