To construct electromechanical services for new buildings that consume nearly zero energy, a holistic approach is necessary. This involves incorporating sustainable design principles and energy-efficient technologies from the outset.

1. Building Orientation: Carefully consider building orientation to maximize natural light and passive solar heating/cooling.
2. Insulation and Glazing: Use high-performance insulation and glazing materials to minimize heat loss/gain and reduce cooling demands.
3. Renewable Energy Systems: Integrate on-site renewable energy systems, such as solar PV or wind turbines, to generate electricity and reduce reliance on the grid.
4. High-Efficiency HVAC: Install high-efficiency heating, ventilation, and air conditioning (HVAC) systems that utilize heat recovery and optimized control strategies.
5. Smart Building Technologies: Implement smart building technologies, including energy management systems and IoT sensors, to optimize energy consumption and identify areas for improvement.
6. Water Conservation: Incorporate low-flow fixtures and greywater reuse systems to minimize water waste and reduce potable water demand.
7. Waste Reduction: Design buildings with waste reduction in mind by incorporating recycling facilities and minimizing packaging materials.

By integrating these sustainable design principles and energy-efficient technologies, it is possible to construct electromechanical services for new buildings that consume nearly zero energy, reducing their environmental impact while providing a comfortable and healthy indoor environment for occupants.
