Topic #1: 100% Natural Ventilation Design for a 1940s Retrofit Building (Kasper Hoejmark Ravn)
Through our reference case project, HouseZero, for Harvard University, Kasper will take the participants through the engineering solutions used to design a 100% natural ventilation solution. This building is for the Harvard Center for Green Buildings and Cities department, and includes the old 1940s structure. With Boston’s geographical location on the Northeast coast, it can be tough to design a facility where natural ventilation is the only ventilation strategy utilized throughout all four seasons.

After the sessions, the attendees will have knowledge of:
• How external CFD is used for fine-tuned window control. The system is partly controlled by wind pressure which can be predicted for each individual window.
• How simple Air Change Calculations can be used in the design phase to ensure a sufficient opening area. This process can save time in relation to the dynamic simulations.
• When Dynamic Simulations and Internal CFD is necessary in a Natural Ventilation project to obtain an optimal indoor environment. These kinds of simulations can be very expensive and it is therefore important to know when they can benefit the design.
• How to use Dynamic Simulations in a building without Mechanical Ventilation to determine alternative strategies, based on the number of critical hours, for improved thermal comfort and acceptable levels of humidity.

Topic #2: Natural Ventilation Design: Two Case Studies (Rubina Ramponi)
The talk will illustrate two case studies of natural ventilation design to stimulate a conversation with the audience on the link between natural ventilation and the local climate and environment. Available methods for assessing the site specific natural ventilation potential, including the use of experimental facilities and numerical methods, will be briefly introduced and discussed through project work.

Kasper Hoejmark Ravn | Building Performance Engineer | WindowMaster
Rubina Ramponi | Advanced Technology and Research Engineer | ARUP

Kasper Hoejmark Ravn has a Master’s Degree in Civil Engineering from the Technical University of Denmark (DTU) specializing in indoor climate, optimal ventilation design and energy-efficient construction. He has experience with several software tools in relation to Dynamic Building Simulations and CFD. As a Building Performance Engineer for WindowMaster International he works specifically on all the natural
ventilation design projects throughout the US.

Rubina Ramponi is an engineer in Arup’s Advanced Technology and Research team, working in the area of wind engineering and environmental physics. She applies computational methods and experiments to gain an understanding of outdoor thermal comfort, pedestrian level wind conditions, reflected solar heat and glare.
