How we design engineering systems
Engineering systems design is based on the architectural drawings: floor layouts, sections and a formalised design brief.
For a heating project we need to know the building's heat loss. For that you either run a thermal calculation or take the normative value, which under current standards corresponds to an energy-efficiency class of at least "C". This means the design load on the heating system will be around 100 W/m². From this we size the boiler room and the heating equipment capacity.
If needed, we take on the heat-loss calculation for the project, an energy audit of the project, or an energy survey of an existing building.
For a water supply and sewage project we need not only the architectural and interior solutions but also the soil conditions on the plot. The choice of equipment, the placement of systems and their cost all depend on this.
For a ventilation project with heat recovery we need the function of each room, the number of occupants and the location of the equipment that will require servicing.
To get everything right, engineering systems should be designed at the earliest stage — when the architectural solutions exist but the structural sections are not yet finalised and can still be adjusted: embedded parts can be laid in and the necessary utilities routed. The sooner we start, the better the result. Call us for a free consultation.
We design engineering systems for any plan from our house plans catalogue.

Projects are developed on the basis of the architectural project and the client's requirements (underfloor heating, boiler type, radiators).
