Mechanical Engineering Services
Energy-conscious, buildable mechanical building services design — comfortable, efficient and compliant environments, from concept through to site.
Get in touchMechanical design sized on calculation, not rules of thumb
JBSE Consulting Engineers provides full mechanical building services design across commercial, residential, industrial and public-sector projects. That covers heating, ventilation and air-conditioning, domestic water services and above-ground drainage, together with the load calculations, plant selections, drawings and specifications needed to procure and install them.
Systems are sized against calculated heat losses, gains and ventilation rates rather than assumed loads, because oversized plant costs money twice — once at purchase and again every year it runs. Energy performance and low-carbon options are considered from the outset, so Part L compliance is designed in rather than retrofitted at the end of the process.
A practical, time-served background in building services means plant space, access for maintenance and replacement, service routes and installation sequence are resolved on the drawings. Coordination with the electrical, public health and structural packages happens as the design develops, so plant loads, builder's work and riser space are agreed rather than discovered on site.
Complete mechanical engineering capabilities
Every element of the mechanical package, from comfort and ventilation strategy through to plant upgrades and technical review — grouped by the part of the project each belongs to.
HVAC & comfort
Heating, ventilation & air-conditioning (HVAC) design
Heating, cooling and ventilation systems designed to CIBSE guidance, sized on calculated loads and coordinated with the building fabric and structure.
Energy-efficient & low-carbon building services
Heat pump and low-carbon plant options, heat recovery and control strategies assessed against Part L, running cost and practical installation.
Water & drainage
Domestic water services
Hot and cold water services sized on realistic demand, with storage, distribution and temperature control designed for compliance and performance.
Above-ground drainage
Soil, waste and rainwater drainage designed to the Building Regulations and the relevant BS EN standards, coordinated with structure and risers.
Delivery & upgrades
Plant replacement & refurbishment schemes
Like-for-like and upgrade plant replacement designed around existing constraints, access routes, phasing and keeping occupied buildings running.
Mechanical surveys, specifications & technical reviews
Condition surveys of existing installations, mechanical specifications and tender documentation, and independent review of contractor design submissions.
Designed to the guidance your systems are assessed against
Mechanical designs are developed to CIBSE guidance and the Building Regulations — notably Part L for energy efficiency and Part F for ventilation — with the relevant BS EN standards applied to equipment, water services and drainage. Manufacturer requirements are coordinated alongside, and the mechanical design is developed in step with the electrical and public health packages so plant electrical loads, drainage connections, riser space and builder's work are agreed rather than assumed.
