Integrative Sustainable Computational and Simulation Design for the Passive Restoration of Existing Historic Building Structures

A sustainable computational and simulation restoration analysis has been performed on a historic public use building structure "Misselwood" located in the town of Beverly in the north shore of Massachusetts, USA. The design focuses on optimizing the most effective building systems in energy savings for historic buildings. The systems include the building shape, site, passive solar heating, lighting and passive low energy cooling. The order of design priority for that specific structure, being in New England, is heating, lighting and cooling with expenditures of 56.8%, 44.0% and 30% respectively. The structure shape (total floor area) and number of stories will increase heating or cooling usage by 24% while the building layout of the individual spaces and number of windows within the spaces will provide conservation measures for daylighting, cooling and heating load reductions. The passive heating requirements, for the first floor spaces, are approximately 8% efficient with no required active mitigation. For daylight analyses of the office spaces on the second level, the annual potential daylight savings is at 51%. The passive cooling requirements for the first floor spaces located at the corners of the structure is at 91% efficiency while for the center spaces facing the south is at 75%. Architects and engineers must implement integrated computational analyses to accurately quantify energy efficiencies of building systems of existing historic structures.
