Concept:
Energy simulation software is used in building design to analyze:
• Building energy consumption,
• Thermal performance,
• Daylighting,
• HVAC efficiency,
• Sustainability and environmental impact.
These tools help architects and engineers create energy-efficient and sustainable buildings.
Step 1: Analyze each software listed in the question.
• A. Design Builder -- A widely used software for building energy simulation and performance analysis. \checkmark
• B. Inscape -- Mainly a real-time rendering and visualization software, not primarily used for energy simulation.
• C. Canva -- Graphic design software unrelated to building energy simulation.
• D. Ecotect -- Software used for environmental and energy analysis of buildings. \checkmark
• E. Archi CAD -- Primarily a BIM and architectural drafting software rather than an energy simulation tool.
Step 2: Identify the correct combination.
The software used for energy simulation are:
\[
A \; \text{and} \; D
\]
Therefore, the correct answer is:
\[
{A\; \text{and}\; D\; \text{only}}
\]
