Final answer:
Evaluating energy consumption during the design process involves assessment principles and strategies for energy efficiency, the role of energy consultants, and cost-effective methods to reduce energy usage in homes and commercial buildings.
Step-by-step explanation:
Evaluating energy consumption early in the design process is crucial for improving the energy performance and efficiency of buildings. Various energy assessment principles suggest a comprehensive approach, including analyzing heating and cooling systems which are major energy users in homes.By optimizing building materials, window placement for maximum solar gain, and enabling better air convection, energy-efficient homes or even zero-energy buildings can be designed.
Furthermore, the role of an energy consultant is highlighted as a valuable career path with the rising cost of energy. Energy consultants are tasked with measuring and analyzing energy flows, ensuring good indoor air quality, and employing passive measures to control heat loss. This consultation is increasingly relevant for both commercial and domestic environments.
Finally, cost-effective strategies for energy savings, such as using higher efficiency devices (e.g., compact fluorescent light bulbs), and limiting the use of high-power devices that operate for extended periods (e.g., water heaters and air conditioners) are also addressed. Each strategy revolves around the notion that energy consumed is a product of power and time, suggesting the reduction of either aspect, or both, to lower energy costs.
