Mechanical Design
(HVAC & Plumbing)
Mechanical Design Case Studies
At LENASSI we offer design of complete mechanical systems, covering everything from heating, cooling, ventilation, air conditioning, heat recovery and plumbing.
We particularly specialise in:
- Heat pump systems: air/water/ ground as heat source and sink
- District heating and heat exchangers (hot water and steam)
- Use of waste (excess) heat in industrial and other applications (e.g. heat pumps that use waste heat as source, heat recovery systems that send heat back into district heating systems, etc.), energy recovery
- Thermal energy storage (TES), such as ice banks
- Clean rooms and special climate
We also have extensive experience with designing:
- Ventilation (air distribution systems, industrial ventilation)
- Air-conditioning
- Exhaust systems: kitchen exhaust, fume hood
- Heating and cooling systems of all types
- Smoke management: zone smoke control, stairwell and elevator pressurization
- Boiler plants, chiller plants
- Chilled water systems, chilled water plants: water and air cooled
- Heating water systems
- Process cooling systems
- Central plant design
- Geothermal heat pump systems
- Automation of building systems
We also offer designs of complete plumbing and other piping systems, which can include any of the following:
- Cold and hot water distribution
- Sanitary waste and vent
- Compressed air
- Laboratory, hospital, speciality piping: medical and technical gases, specialty gases, high-purity water, process water, chemical & acid waste drain and vent
- Water re-use systems
- Storm, foundation and roof drain
- Central steam and chilled water distribution
- Fire protection (wet, pre-action, dry): sprinkler systems, fire pumps, standpipe systems, clean agent systems
Types of services we offer
- Capturing and documenting existing conditions
- Conceptual designs
- Detailed drawings
- Detailed functional specifications – as an input for BMS and commissioning
- Supervision and control of integration of functional specifications into BMS (SCADA, PLC)
- Designer supervision – technical consultant, “owner’s engineer”, oversight of construction
- Peer review
We possess considerable experience with designing renovations and retrofittings that require placing new equipment into existing spaces. This includes challenges presented by the use of equipment containing new types of cooling gases with varying levels of flammability and toxicity within existing spaces (e.g. calculation of the required amount of ventilation in case of flammability).
How do we conduct our work
At the outset of each project, our engineers carefully review project objectives along with any applicable codes, standards, and technical requirements.
In our work, we utilize the latest design software such as Autodesk Revit, AutoCAD, Navisworks, and ReCap, and continuously integrate new digital tools to enhance our design capabilities. Ongoing professional trainings ensure our team is well equipped to use all available design technologies and libraries. We offer both traditional 2D design as well as 3D and BIM (Building
Information Modeling) design.
Throughout every project, we place strong emphasis on clear communication with all relevant stakeholders (e.g. architects, contractors) to prevent any design and implementation discrepancies.
