Optimizing energy performance in a zero energy house during periods of no occupants is important to reduce wasted energy and achieve maximum efficiency. Here are some strategies to consider:
1. Smart Automation Systems: Install a smart home automation system that allows you to control and monitor energy usage remotely. You can schedule the system to turn off lights, adjust temperatures, and switch off appliances when the house is unoccupied.
2. Occupancy Sensors: Install occupancy sensors or motion detectors in rooms to automatically turn off lights and other electronics when no one is present. This ensures that energy is not wasted on unnecessary lighting.
3. HVAC Optimization: Adjust the thermostat settings to reduce heating or cooling during periods of no occupants. Set the temperature to a slightly higher range in summer and lower range in winter. Alternatively, you can use programmable thermostats to schedule temperature adjustments based on occupancy patterns.
4. Energy-Efficient Appliances: Use energy-efficient appliances and electronics that have standby power-saving features. Ensure that appliances are turned off and unplugged when not in use, as even in standby mode, they consume energy.
5. Natural Ventilation: Utilize natural ventilation techniques to reduce the need for air conditioning and artificial lighting. Design the house with operable windows, skylights, and consider implementing passive cooling strategies such as shading and cross-ventilation.
6. Insulation: Ensure the house is properly insulated to minimize heat gain or loss during periods of no occupants. Insulation helps maintain a consistent indoor temperature, reducing the reliance on HVAC systems.
7. Energy Monitoring and Tracking: Install energy monitoring devices to analyze and track energy consumption patterns. This allows you to identify energy-intensive areas and make necessary adjustments to minimize wasted energy.
8. Solar Energy Systems: Incorporate solar panels to generate electricity during daylight hours, even when the house is unoccupied. Excess energy produced can be fed back into the grid or stored in battery systems for later use.
9. Seasonal Adjustments: Understand the seasonal changes in energy demand and optimize the house's energy performance accordingly. Adjust the HVAC systems, lighting, and energy usage settings based on changing outdoor temperatures and daylight availability.
10. Continuous Commissioning: Regularly commission and re-commission all energy systems to ensure they operate at their peak efficiency. Identify and rectify any energy leaks or system malfunctions during vacant periods.
Remember, it is always beneficial to consult with professionals in green architecture or energy efficiency to design and optimize a zero energy house effectively.
