The newly refurbished, three-story healthcare facility will provide primary care and local community services ranging from injury treatment and dental surgery to general surgery and renal dialysis. The GBP 4.2 million project required Capita Symonds to determine an energy-efficient ventilation strategy, compliant with United Kingdom building regulations and sympathetic to the age and space limitations of the building, while improving the patient/staff experience. To accommodate these design challenges, Capita Symonds needed reliable modeling and energy simulation technology.
Using Bentley Hevacomp, Capita Symonds constructed a 3D energy simulation model to analyze and determine the frequency of overheating within the facility. The analysis identified overheating as a significant problem forcing Capita Symonds to rethink its servicing strategies for a cost-effective ventilation system that would optimize internal conditions for building users.
Modeling the building and simulating its energy performance using Bentley Hevacomp allowed Capita Symonds to accurately predict overheating within various rooms of the Grade II listed U.K. building. Quantitatively demonstrating overheating as a significant problem justified the need for mechanical cooling and ventilation. Given the major cost implications of an electrical cooling system, Capita Symonds was forced to look at more cost-effective ventilation solutions to achieve optimal internal temperatures within the facility.
Capita Symonds used Bentley Hevacomp’s CAD input program to model the hospital building. Using Bentley Hevacomp’s design simulation to analyze the frequency of overheating, the team determined that many parts of the building significantly overheated beyond the maximum recommended temperature of 28 degrees Celsius for more than 50 hours per year. Bentley software enabled Capita Symonds to quantitatively demonstrate the overheating implications to the Hospital Trust, justifying the need for mechanical cooling and ventilation and necessitating the team to rethink its servicing strategies for a more cost-effective solution.
