Mechanical Design and Consultancy

Design that considers comfort and operation together

Different operating hours, internal heat gains and ventilation needs require building system choices to be considered together. Our mechanical design service develops heating, cooling, ventilation and water systems around those needs. AECO coordinates equipment and control decisions with architectural layouts, electrical infrastructure and operational objectives, developing the design from calculations through implementation documents.

The service supports clients and design teams planning new buildings or assessing existing systems and design documents. We begin by reviewing available information, system conditions and operational priorities. The design stage, calculations and drawings required, and boundaries of technical follow-up define the scope of work.

When evaluating heating and cooling needs, we consider system alternatives and equipment selection criteria together. Understanding the conditions in which demand arises provides a broader basis for decisions than equipment characteristics alone. We explain how the options relate to operating schedules, control strategies and space requirements.

Ventilation and plumbing design follow the building's use and project-specific needs. We coordinate the relationships between mechanical systems, architectural layouts, electrical infrastructure and automation. Energy efficiency objectives are considered alongside indoor conditions. This makes the connections between different teams' decisions visible as the design develops.

We start by reviewing climate data, operating schedules, indoor conditions and any existing systems. After clarifying design assumptions, we develop calculations and comparisons of alternatives. The selected approach is translated into drawings and technical specifications. Keeping the relationship between calculations and drawings clear provides a common reference for later technical reviews.

During design, we assess changes from other disciplines and their implications for system decisions. Within the agreed technical follow-up, we address implementation questions and clarify testing and commissioning needs with the project team. We distinguish matters that require a design explanation from those that need further investigation or a decision by the team.

We select technical references according to building and system use. For example, ASHRAE 62.1 — Ventilation and Acceptable Indoor Air Quality is a relevant reference for the building types it covers. In Türkiye, Binalarda Enerji Performansı Yönetmeliği, Türkiye’s regulation on building energy performance, provides the local framework for energy performance. Technical requirements are related to the relevant systems and building use. Where a project has a certification objective, we coordinate the necessary design information with the relevant consultancy process.

Deliverables include the mechanical design basis, calculations, drawings and technical specifications appropriate to scope, system comparisons and coordination notes. The documents explain the basis of the selected solution alongside matters that require review.
