Natural Ventilation as defined by ASHRAE is the flow of outdoor air caused by wind and thermal pressures through intentional openings in the building’s envelope.
Passive cooling using this strategy is risky without knowing the proper guidelines of Natural Ventilation Design. Cooling is achieved by relying on outdoor wind speed and temperature to remove the heat gain of the indoor space. Correct analysis of the weather condition at a project location should also be studied and analyzed for the applicability of the Natural Ventilation Design, for in this condition the air properties are most significant. In current building design norms, even in locations where natural ventilation would be incredibly effective, the option of applying such strategy is usually abandoned and ignored in favor of more expensive, reliable and complex mechanical climate control / air conditioning systems.
Natural Ventilation Strategy allows architects and HVAC designers to see the impact of the passive cooling design in coordination with the project’s aesthetics. Architects will strategically place the openings that will satisfy the architectural concept design as HVAC designers analyze and validate the size of the openings and the amount of airflow passing through these openings that will serve its purpose and functionality.
Green Technologies, as pioneers in green engineering and sustainability in the region, has over 30 years of experience in HVAC engineering design as well as the region’s weather pattern, and thus would best qualify for analyzing the applicability of the passive cooling design strategy.
Together, energy modeling and natural ventilation will provide a sustainable design that is energy efficient and capable to meet the required thermal comfort of the occupant. The acquisition of comprehensive engineering software such as Design Builder, the best instrument in this case – that analyzes and studies such design, enables Green Technologies to offer the best of services in Natural Ventilation Design Consultancy. This will include the following services:
