Final answer:
The main ASHRAE standard for HVAC systems is ASHRAE Standard 90.1, focusing on energy-efficient building design. HVAC efficiency is also measured by SEER for cooling and HSPF for heating, while the Clean Air Act regulates air quality impacts of HVAC systems. Energy conservation and environmentally friendly building designs are becoming integral to HVAC system considerations.
Step-by-step explanation:
The main ASHRAE standard that HVAC systems must adhere to is ASHRAE Standard 90.1, titled "Energy Standard for Buildings Except Low-Rise Residential Buildings."
This standard provides the minimum requirements for the energy-efficient design of most buildings and includes provisions for HVAC systems to ensure they operate effectively while minimizing energy use.
Additionally, HVAC systems are also subject to the Seasonal Energy Efficiency Ratio (SEER) for cooling and the Heating Seasonal Performance Factor (HSPF) for heating, which measure their efficiency over the cooling and heating seasons, respectively.
Furthermore, the Clean Air Act plays a crucial role in ensuring that HVAC systems contribute to maintaining acceptable air quality standards. Building codes in various municipalities also dictate safety requirements that include working ventilation and heating systems, as part of the habitability criteria for homes. These requirements help to protect the health and safety of building occupants.
In an effort to ensure energy conservation and environmental impact, the industry has trended towards more sustainable solutions, such as environmentally friendly homes that reduce conventional heating and cooling needs through better design and building materials. Innovative designs aim to create zero-energy houses, which are highly efficient and comfortable even in extreme climates.
