What aspect of electrical engineering services is addressed during the DD phase?

The focus on types of energy sources during the Design Development (DD) phase is crucial for ensuring that the architectural design aligns with the intended energy systems for the building. At this stage, the integration of electrical systems is critical as architects and engineers collaborate to refine the design details. Understanding energy sources allows for informed decisions regarding electrical loads, system capacity, sustainability measures, and the overall energy efficiency of the building.

This phase involves not only outlining the types of electrical systems to be used but also considering renewable energy options, such as solar or geothermal, alongside traditional power supplies. These choices affect not just the electrical infrastructure but can also have implications for the building's environmental impact, operational costs, and compliance with energy codes.

In contrast, while durability of building materials, structural design, and environmental assessments are important components of the design process, they are less specifically tied to the electrical engineering services addressed during the DD phase. The emphasis at this stage is primarily on the operational aspects and technicality of energy supply and management within the building design.
