Target Carbon Management was created in 2016 as a renewable energy and thermal retrofit consultancy, supporting clients who wanted buildings that perform better, cost less to run, and tread more lightly on the environment. Since then, TCM has evolved into William Jones Architect—bringing the same evidence-led approach into architectural design. The business still trades and communicates under the Target Carbon Management name, reflecting its roots in environmental performance and retrofit.
What Target Carbon Management Is
Target Carbon Management is an energy consultancy for the construction industry. It helps project teams understand how design decisions affect energy use, comfort, and carbon—both in new build and, especially, in existing buildings where thoughtful retrofit can make the biggest difference. TCM’s work typically supports architects, developers, homeowners, contractors, and design teams by translating performance goals into practical fabric and services strategies that can be delivered on site.
- Renewable energy options appraisals and integration guidance
- Thermal retrofit strategy: insulation, airtightness, thermal bridging, and ventilation approaches
- Performance-led specification support for building fabric and building services
- Buildability reviews and coordination with contractors to reduce performance gaps
- Client-friendly advice that links technical measures to cost, disruption, and long-term value
The Golden Thread: Environmental Design in Every Project
The lessons learnt through years of environmental design work are a golden thread that can be seen in all of William Jones Architect’s projects. That means early attention to orientation, daylight, and overheating risk; careful detailing to improve fabric performance; and a practical understanding of how buildings are actually constructed and used. Whether the brief is a sensitive renovation, a contemporary extension, or a deep retrofit, performance is treated as part of good design—quietly embedded in the layout, materials, and technical decisions rather than added as an afterthought.
How This Helps Clients
- Clear, realistic routes to lower energy demand and improved comfort
- Design decisions supported by evidence and practical retrofit experience
- Better coordination between architecture, building services, and buildability
- Performance improvements that respect existing fabric and architectural character
If you are planning an extension, renovation, or retrofit and want an architect who can carry performance thinking from concept through to delivery, William Jones Architect can help. An initial discussion can clarify your goals, constraints, and the most effective path to a comfortable, efficient building.
