How Effective Ventilation Design Impacts Energy Efficiency Ventilation is often overlooked in building design, yet it is crucial for energy efficiency and indoor air quality. At AE Consulting, we prioritise designing ventilation systems that are both highly efficient and fully compliant with New Zealand’s Building Code Clause G4 (Ventilation) and H1 VM3 (Energy Efficiency) standards. Why is it so critical? Without effective ventilation, HVAC systems are forced to work harder, leading to increased energy consumption and higher costs. Thoughtful design can eliminate inefficiencies and enhance building performance. Here’s how: 1️ Controlled Airflow: We regulate fresh air intake and exhaust, minimizing heat loss and reducing the load on HVAC systems. 2️ Heat Recovery Ventilation (HRV): HRV systems capture exhaust heat and precondition incoming air, reducing energy use. 3️ Duct Sealing & Sizing: Properly sealed ducts prevent air leaks and optimize system efficiency, following best practices to limit pressure drops. 4 Optimized Fan Selection: Choosing energy-efficient fans and minimizing duct resistance reduces the energy required for air circulation. 5️ Natural Ventilation: Strategic placement of windows and passive ventilation reduces reliance on mechanical systems. The Benefits:  -Reduced energy costs  -Healthier indoor air quality  -Compliance and improved sustainability At AE Consulting, we design ventilation systems that meet regulatory standards and promote energy efficiency. Let’s work together to create sustainable solutions for your next project.

I fully support this. Although in NZ I prefer to use MVHR rather than HRV due to the national confusion the later acronym causes. Also would emphasise that the controlled air flow should consider indoor air quality for the demand control, which I think is implicit in what you’ve said but might not be for others.

AE Consulting designing to exceed regulatory standards should be your mission. Meeting regulatory standards does nothing for energy efficiency.

Do we finally have a supplier-independent ventilation consultancy available for residential projects in Aotearoa?
