Four Seasons Hotel - HVAC Analysis

Using architectural drawings to create a 3D model of the building, VE Solutions were able to use the IES VE to consider how heat conduction from people, lighting, the sun and through the building itself would affect comfort levels. When it came to right-sizing the HVAC equipment, many different parameters affecting performance and comfort levels were considered. The resulting 3D model meant VE Solutions could really visualise the space and analyse specific areas of concern in more detail, in a way not possible with just a spreadsheet full of data. As well as reducing the cost of the HVAC equipment, the integrated nature of the VE modules and their ability to handle heavy load calculations and hourly data, meant that VE Solutions could more accurately size equipment to optimise performance by room. As well as providing ample cooling on a hot day, right-sized fan coil units de-humidify more effectively on a humid day. That was very important to the Four Seasons because New York gets very humid in the summer and oversized equipment won’t take out the moisture. “The VE has taken our ability to value engineer HVAC systems to a new level. The sophisticated way the ApacheSim, ApacheHVAC and SunCast modules integrate together enabled us to gain a better understanding of the building loads, which helped us reduce HVAC costs while actually improving the comfort of the building. We were able to reduce the amount of equipment, ductwork and piping required, significantly reducing costs and contributing to the client’s goal to start construction this year.” Eugene Siterman, Managing Director, VE Solutions Group
