3S MEP offered extensive mechanical, electrical, and plumbing (MEP) design solutions for the restoration of a historic Veranda house, which, at 141 years old, suffered substantial damage in a fire incident in Nantucket, MA. The 14,000 sq ft building consisted of a Lounge, living rooms, guest rooms, bathrooms, commercial laundry, and a kitchen.

We conducted commercial heat load calculations to determine the heating and cooling requirements of the project space. Based on the calculations, the team designed the VRF systems to efficiently distribute conditioned air throughout the building. To meet the heating and cooling demands, 3S MEP selected ceiling-concealed and split units and outdoor units, ensuring comfort and energy efficiency. To enhance indoor air quality, a dedicated outdoor air system (DOAS) with a high-efficiency Energy recovery ventilator (ERV) has treated and preconditioned the incoming outdoor ventilation air using the exhaust air. The careful consideration of these mechanical design elements will provide a comfortable and healthy environment for the occupants.

The plumbing design for the hotel included the precise and deliberate design of the sanitary waste system, grease, and oil interceptor system, and the cold/hot water system to provide a reliable and consistent water supply throughout the hotel. The Water heater sizing was carefully determined to meet the hot water demands for all the bathrooms and kitchen area, considering factors such as usage patterns and fixture requirements. Furthermore, we also developed a gas piping system design to facilitate the safe distribution of gas within the building while catering to the needs of all mechanical and kitchen appliances.

Electrical design services included lighting and power layouts that considered both functionality and energy efficiency. The team conducted load calculations to determine the electrical demand and designed the electrical system accordingly. Developed a Single Line Diagram (SLD) to illustrate the electrical connections and distribution within the facility.
