Which factors influence a site's energy efficiency aside from physical orientation?

The choice highlighting climate conditions and building materials as influencing factors of a site's energy efficiency is particularly relevant. Climate conditions, including temperature variations, humidity, and sunlight exposure, significantly impact how a building performs in terms of energy consumption for heating, cooling, and lighting. For instance, a building located in a hotter climate may require more robust insulation and cooling solutions to maintain comfort levels, directly affecting energy usage.

Building materials also play a critical role in energy efficiency. The thermal mass of materials, their insulating properties, and their sustainability can either enhance or hinder a building's ability to regulate temperature effectively. Materials that reflect solar heat can minimize cooling demands, while those with good insulation properties help maintain indoor temperatures, thereby reducing the need for artificial heating and cooling systems.

Other choices, while they may have relevance to site planning, do not have as direct an effect on energy efficiency as climate conditions and building materials. For example, lighting fixtures installed are important for energy efficiency but are more related to energy use within the building rather than site-specific conditions. The number of floors in the building might influence its design and overall energy demand but is not as critical of a factor as environmental conditions and material choices. The location within the city can affect access to energy sources and infrastructure but
