Energy Audit - Tangent Space

Discover Where Your Building is Wasting Energy and How to Stop It

Our current housing stock emits over 33% of UK greenhouse gases, and it is predicted this figure will rise to 55% by 2050.

In the UK, we have the oldest and least energy-efficient housing stock in Europe. With heating and fuel bills only going one way, and global warming impacting us on a daily basis, we face a critical target: achieving net-zero carbon emissions from our homes by 2050.At Tangent Space, sustainability isn’t an afterthought or a compliance box to tick—it runs through the very core of our practice. We love delving into exactly how much energy a building is currently using to help you unlock substantial cost savings and environmental benefits.

Whether you are looking to cut soaring utility bills, eliminate drafts, or future-proof a property during a major renovation, our technical expertise provides the exact roadmap you need.

What Is It?

We conduct a comprehensive, holistic review of a building’s physical envelope and internal systems. We evaluate:

The Building Fabric: Walls, windows, doors, floors, and insulation levels to check for structural heat loss.

Active Systems: Current heating systems, ventilation (HVAC), and interior/exterior lighting.

What you Recieve

You receive a clear, bespoke action plan tailored room-by-room, breaking down your options into three practical investment tiers:

Low

Medium

High

Every recommendation includes projected utility bill reductions and a clear Return on Investment (ROI), helping you make informed, budget-conscious decisions to lower your carbon footprint and energy bills.

Our purpose is to drive the transition to a low-carbon built environment across Sussex and the South East through regenerative architectural design, retrofit-first strategies, and healthy, bio-based materials - creating resilient spaces that enhance human well-being while restoring local ecosystems.

Company Strategy

As an architectural practice operating in the UK building sector - where construction and building operations account for nearly 40% of global carbon emissions - our purpose is directly aligned with market demand for decarbonisation, energy security, and strict climate building regulations (e.g., Future Homes Standard, LETI, and RIBA 2030 Climate Challenge). Delivering high-performance, low-impact design secures our competitive advantage, attracts sustainability-focused clients, and future-proofs our commercial pipeline.

Our purpose governs how we allocate resources, select projects, and manage our practice:

We actively prioritise retrofit, adaptive reuse, and low-energy projects over energy-intensive new builds or carbon-heavy developments.

We integrate circular economy principles by specifying bio-based, locally sourced, and low-embodied carbon materials across 100% of our design projects.

We embed climate performance goals directly into our project briefs and client relations.

Key Metrics & Integration Mechanisms

Conducting embodied and operational carbon benchmarking on all major design projects.

Sourcing a minimum of 75% of specialist consultants and material specifications within a 50-mile regional radius.

Enforced through our public Climate Action Plan, Ethical Client Policy, and annual progress reporting to stakeholders.
