05 · Embedded Engineer · 8 sites

A 33% reduction across the council's portfolio.

A 12-week embedded engineering placement at Lewes District Council, covering eight sites across the coast — leisure centres, swimming pools, depots and a Grade II-listed Marine Workshop. Baseline established, the FM team upskilled, funding secured, and a brief that ran long enough to deliver the implementation, not just the report.

01 · The Challenge

Eight sites, one stretched FM team, and a Net Zero plan to evidence

A council with the right ambition and a small team — needing technical capacity it couldn't justify hiring full-time.

Lewes District Council had a published Net Zero plan and an FM team running eight buildings — including two energy-hungry leisure centres with swimming pools — without an in-house energy engineer. The plan was being asked to deliver real reductions, not just intentions.

The brief was for an embedded engineer: someone in the team for 12 weeks, walking every site, building the baseline, finding the funding, and — critically — upskilling the FM team to keep going after the placement ended. Not a report-and-leave.

Public-sector finances meant every recommendation had to be paired with a funding route. Salix, PSDS, capital programme — the team needed not just 'what to do' but 'where the money's coming from'.

Pool plant dominates

Three pool sites carry 67% of the carbon. CHP, dehumidification & pool covers prioritised — biggest reductions, fastest.

Heritage constraints honoured

The Marine Workshop & Listed Library required fabric solutions compatible with conservation — done within consents.

Funding routed

Each measure paired with a funding source: Salix loans, PSDS grants, capital programme — no abandoned actions.

03 · Key Findings

Six themes — across pools, plant rooms and listed walls.

F.01

Pool hall dehumidification

Largest single load on the leisure sites. Heat-recovery upgrades and tighter setpoint control modelled across all 3 sites.

F.02

Pool covers — manual to automatic

Covers were installed but rarely used. Automatic deployment + staff procedure now embedded.

F.03

BMS schedules adrift

Six of the eight sites had BMS schedules that had drifted out of step with current opening hours. Recommissioning saved 11% portfolio-wide.

F.04

Heritage fabric upgrades

Internal insulation & secondary glazing routes worked up for the listed buildings — within conservation officer consents.

F.05

Funding pipeline mapped

Each measure tagged with a funding source: Salix, PSDS, capital. £820k secured during the placement.

F.06

FM team upskilling

Seven FM staff trained on energy-management fundamentals — they own the next cycle, not us.

04 · The KEES Approach

Be in the team. Don't be a visitor.

Embedded means embedded. Desk in the office, badge on the lanyard, in the FM team meetings. Reports get filed; embedded engineers get things done.

STEP 01

Walk every site, week one

Eight sites in five days with the FM lead. Plant rooms, pool halls, roof voids — see it before any spreadsheet opens.

STEP 02

Build a portfolio baseline

Twelve months of consumption data per site, per fuel. Reconcile with bills. Find the obvious anomalies first.

STEP 03

Prioritise by impact, not by ease

67% of carbon sat at three pool sites. We didn't pretend otherwise — biggest measures got drawn first.

STEP 04

Pair every measure with funding

Salix loan applications drafted. PSDS submission supported. Capital programme cases written. £820k secured.

STEP 05

Train, then hand over

Seven FM staff through energy-management fundamentals. Tracking dashboard in their hands, not ours.

06 · Client testimonial
We needed someone who'd be in the team, not visiting it. Twelve weeks in and we were running our own tracker, with funding secured for nearly everything on it. Best thing we've done for our Net Zero plan.
