The Park One Office Building was constructed as a Class 1 premier office space for Lincoln, Nebraska. The office building overlooks Holmes Lake and provides one of the best office locations in Lincoln.
The first and second floors of the Park One Office Building are heated and cooled with fan coil units. The fan coil units are located above the finished ceiling and serves approximately 1500 square feet.
Each fan coil unit provides 1950 cfm of air, nominal 5 tons of cooling and 34,400 BTU’s of heating. The fan coil units are all electric and are connected to the electrical meter for each tenant area. Each fan coil unit has a thermostat strategically located in the tenant space. Five ton air-conditioning units are located on the roof with refrigerant piping to DX cooling coils located in each fan coil unit.
The third and fourth floors are heated and cooled with roof top units. The roof top units are located on the roof with ductwork extending to the tenant spaces on third and fourth floors. Each roof top unit serves approximately 1500 square feet.
Each roof top unit provides 1950 cfm of air, nominal 5 tons of cooling and 92,000 BTU’s of heating. The roof top units are gas heating with electric cooling and are connected to the gas and electrical meters for each tenant spaces. Each roof top unit has a thermostat which will be strategically located in the tenant space. Each roof top unit provides fresh air to the tenant spaces and are equipped with economizers to provide free cooling when outdoor air conditions allow.
The heating is supplemented with perimeter electric baseboard heating units located below the windows. Each baseboard heater will be controlled from a thermostat mounted on the wall of the perimeter office. The perimeter heating will provide additional comfort to the perimeter offices while cooling from the roof top units is required for the interior spaces.
Fresh air is provided to the space to provide quality indoor air for all tenants. The fresh air is brought in through the roof top units. The HVAC system also meets the requirements of the Uniform Building Cold for fresh air. 15 cfm per person of fresh air is provided. For the purposes of the design, an occupant load of one person for every 100 square feet was used.
The HVAC systems are designed to provide an indoor air environment of 72 degrees at 50% relative humidity.
A 100-amp single phase panel is provided for each 1500 square feet of floor area throughout the entire building.
