Building Services

Mechanical Engineering (building services)

At ONE we pride ourselves on cutting-edge mechanical engineering building services solutions so that clients can rely on compliance, optimal functionality and sustainability.

Many mechanical engineering solutions work hand in hand with electrical engineering and with an award-winning inhouse integrated mechanical and electrical engineering team, ONE offers all aspects of MEP design.

Below are details of some of the services our engineers provide as part of our building services offering.

Sustainable and energy-efficient solutions 

We integrate the latest technologies to optimise energy consumption, reduce environmental impact, and enhance your building’s overall performance.

With inhouse Low Carbon Consultants, our mechanical design engineer’s first thought is always regarding the environment and helping clients to achieve their sustainability and Net Zero goals, which could also provide them with long term savings.

Working with all other disciplines, we start with a fabric first approach through environmental engineering modelling. We look at ways that minimise the need for mechanical interventions for example, the need for air conditioning could be dramatically reduced by overheating analysis, building orientation, daylight modelling, solar shading and passive cooling techniques.

We provide the most suitable sustainable options for each individual project, including renewable energy for example: rainwater harvesting, Photo Voltaic Panels, air source and ground source heat pumps. In refurbishment projects, we dovetail with existing systems reusing wherever possible and replacing where appropriate.

HVAC mechanical design (Ventilation, heating/cooling and air conditioning)

Our building services engineers specialise in designing heating, ventilation, and air conditioning solutions tailored to your building’s unique needs.

For example, air flow in different commercial settings will have different requirements. In an office setting, the temperature and comfort level is going to be the main concern. In a workshop or warehouse environment, the movement of polluted air to be replaced with clean air through COSHH ventilation systems is imperative for health and safety. We use dynamic thermal modelling and other state-of-the-art software to work with our clients to provide the solution that will work for their individual requirements.

Fire protection systems

Safety is vital and so you need a team you can trust. Mechanical and electrical engineering services often work together, with sprinkler systems and smoke control systems being the mechanical engineering solutions for when a fire is detected alongside electrical fire safety alarms and systems. Our building services engineers design comprehensive fire protection systems to safeguard your people, buildings and investments.

Hot and cold-water: MEP mechanical electrical plumbing systems

A reliable clean water supply and drainage are critical for any building. Our mechanical design engineers design efficient plumbing systems that prioritise water conservation and meet the highest industry standards.

Energy management and building control systems 

Intelligent building controls and the ability to turn off non-essential systems from one remote location can drastically lower your energy use – an approach we use across our projects.

Validation surveys (building surveys)

When carrying out building work on existing properties, we validate the current systems to determine what needs repairing or replacing and reuse wherever possible, saving carbon and costs.

How does mechanical engineering use BIM? 

At ONE, a BIM workflow is business as usual. Our mechanical design engineers use 3D modelling to co-ordinate building services with all other disciplines to identify the most efficient locations and routes for installation prior to construction. Our building services engineers will attach all relevant data to the BIM model, for effective future asset management.

Why choose ONE? 

Our skilled mechanical engineers provide efficient, sustainable and innovative solutions. They are part of our integrated Building Services team and are involved throughout all RIBA Stages, from 1-7. You can be confident that your project has absolute continuity, and that the implementation on site fully matches the design for effective and compliant solutions.
