Robert D Johnson Building <br />Page 6 2023 Building Inspection <br />Interior: Mechanical system, Photos A49-A54 Rating: Varies <br /> <br />A cursory review of the existing mechanical system was conducted – further investigation would be <br />required. <br />Notes: <br />1. Boiler (1968) was recently refurbished and is in good condition. No replacement needed. <br />a. Natural gas fuel. <br />b. Steam feeds existing radiators. <br />2. Rooftop unit was added in 1996 above the gymnasium. <br />a. Unknown at time of report if this is still the same unit. <br />b. Provides ventilation only to gymnasium. <br />3. Primary heat in spaces is provided by steam radiators (there are still some unit ventilator units <br />with outside air closed off). <br />a. Consider changing to hot water for better control. <br />4. There are select areas that have some sort of ventilation but is not consistent throughout the <br />building. <br />a. Recommend adding ventilation through the entire building or at least major occupied <br />spaces. <br />5. Many spaces are cooled only by means of window A/C unit. <br />a. Recommend adding a central chilling plant or review systems that could provide better <br />access to cooled air if spaces are fully occupied. <br />6. Temperature control is currently a Pnuematic system. <br />a. This type is getting harder to service and repairs can be expensive. <br />b. Consider replacing with DDC system for better control if using a building automation <br />system. <br /> <br />Interior: Electrical, Photos A55, A56 Rating: -- <br /> <br />A cursory review of the existing electrical system was conducted – further investigation would be <br />required. <br />Notes: <br />1. Service is adequate for existing needs. <br />a. Needs review if any other mechanical systems were brought online. <br />2. Lighting <br />a. Existing lighting is primarily Fluorescent. If remodeling – Provide LED. <br />3. Telecommunications <br />a. Extensive analog telecommunications system installed. Should upgrade to all digital. <br />i. May require a dedicated data room.
