Electrical Design

Electrical Design

Electrical Load calculations and Cable sizing, distribution and switchgear and earthing designs. 

We can prepare the single line diagrams (SLD) & electrical load lists, specifications and tender documents. 

We also do condition surveys for compliance with regulations and supervise installation work. 

We also can do off grid power systems and size backup supplies. 

Lighting Design

Using advanced 3D software packages we can carry out lighting layouts and lux level calculations to get the right balance of level and ambience, whilst saving energy. 

Full system layouts including emergency lighting can be produced with our end to end service providing the latest in energy saving technologies. 

Generally a good design will fine tune the installed lighting to achieve a 20% energy reduction. Controls and sensors can add 40% or more in additional savings. Thus a good modern design can achieve a ~60% saving on your energy compared to an existing office building. 

"Lighting is responsible for the largest slice of electricity consumption in offices in the UK "

Independent Service Engineers

How We
Can Help

Traditionally heating/services were a standard work package handled by the trades and architects but buildings, regulations and the needs of the client have become more complex over time, and rightly so. Heating is integral to the comfort and well-being of your home/work and is only now been given proper consideration in the build. Also, often it can have the largest impact on operating cost for you in terms of bills and carbon impact over the long-term. In addition, there are a multitude of options available with renewable technologies in a fast-changing market. There can be a considerable cost benefit to have input from specialist independent building service engineers at several stages.
