01 Services

Services — index Four connected domains

Four connected areas, one continuous system.

We work across the full life of a building's systems, from the first calculation through to intelligent operation. Each domain occupies a position in the control loop.

Engineering

Zone · the plant

We design and calculate building services with a focus on performance, reliability and maintainability.

—HVAC sizing and calculation —Mechanical and energy systems —Technical specifications —Systems integration

Automation

Control · the processor

We design and optimise intelligent control systems that keep buildings adaptive and efficient.

—BMS — BACnet, KNX, Modbus —HVAC and shading control —Control sequences —Commissioning

Performance

Sense · the feedback

We help buildings operate as they were intended to, for the people who use them.

—Commissioning and monitoring —Data analytics and fault detection —Indoor environmental quality —Post-occupancy evaluation

Innovation

Model · the digital twin

We turn applied research into practical, future-ready engineering.

—Applied research —AI and data-driven methods —Digital twins —European projects

02 Work

Work — record Challenge · Solution · Impact

A selection of engineering and research work.

For each project we document the challenge, the solution and the measured impact.

Circuito Ricardo Tormo

VIP box renovation

ScopeBuilding services

LocationValencia

BudgetOver €2 M

ClientCircuito del Motor y Promoción Deportiva S.A

Challenge

A high-profile VIP box renovation needed climate systems that stayed reliable under event-day loads, while improving the building's energy performance.

Solution

We delivered a full HVAC design, covering load calculation, system design and control strategy, together with photovoltaic integration.

Impact

Modernised, energy-efficient building services, with on-site renewable generation feeding the building's demand.

HVAC remodelling

ScopeBuilding services

LocationAlbacete

BudgetOver €2 M

ClientAyuntamiento de Albacete

Challenge

Water damage had compromised the convention centre's building services, so the work had to repair and modernise them at the same time.

Solution

We carried out an HVAC remodelling with solar integration, redesigning the systems and optimising their thermal performance.

Impact

Restored and modernised building services, with an improved thermal and energy profile.

P-03 Applied research

Energy-Wise Archetypes

Linking occupant preferences to energy use

TypeApplied research

ProgrammeTU Delft Seed Fund

Funding€20,000

ClientTU Delft Climate Programme

Challenge

Comfort and energy use are usually treated separately, which leaves building controls blind to what occupants actually prefer.

Solution

We built a web-based tool that uses AI archetypes to link each person's environmental preferences — temperature, light, acoustics and air quality — to energy use.

Impact

An occupant-centred control framework based on real preference data, supporting behavioural change and better energy performance.

03 Practice

Practice — profile Practice · Research

An independent engineering consultancy.

Pamtec Engineering specialises in building services, automation and building performance — combining engineering practice with advanced research to design systems that are robust, efficient, and centred on the people who use them.

General notes

Independent

Impartial advice, not tied to any supplier or product.

Human-centred, research-backed

Grounded in current evidence and proven on large-scale projects.

A single partner

From the first calculation through to intelligent operation.

European experience

Across research, policy and practice.

A broad network

Industry and research specialists, so we can match the right people to each project.
