Heating Boiler Plant Design Intent:

The demolition of a remote boiler plant is Phase 3 of a school energy audit. Implementation of this audit is designed to furnish and install highly efficient, high-performance condensing boilers within the existing school based on an estimated return on investment to eliminate the antiquated remote steam boiler plant. This city school business plan also included the future use of the

demolished remote boiler plant land. The DID focuses herein on the demolition of the existing steam heating system with its 2-LPS boilers, underground insulated steam supply and condensate return pipes, boiler feed pump and receiver set, and boiler plant ventilation system. Much of the equipment and materials shall be recycled. The demolition project will be construction management firm with the project leader subcontracting the services of a demolition contractor, heating subcontractor, and other subcontractors as needed.


The newly completed Phase 2 condenser hot water boiler heating system within the school and this Phase 3 boiler plant demolition design intent was based on the process outlined in ASHRAE Handbook 2020, Chapter 1, HVAC System Analysis and Selection, and shall include the following:

  • The owner’s building program goals and additional goals. 
  • System constraints and constructability constraints. The final BOD is based on a decentralized heating system source eliminating the existing steam-to-hot water heat exchangers within the building and removal of the remote boiler plant to accommodate future growth in the next five to eight years as well as: 
  • Safe disposal of equipment, piping, insulation, sheet metal, and automatic controls – both localized controls and school BAS control interface and relocation and upgrade of the school’s existing computerized maintenance management software (CMMS) system to the newly created facility management office within the existing school.


Owner’s Program Requirements and the Project Goals:

  • Functional goals: (refer to Chapter 1, 2020 Handbook). Budget goals: energy audit costs, budgeted operating cost, and life cycle cost of the Phase 2 condenser boiler installation. Timeline goal: creation of empty site with grass covering the area within six months. Management goals: maintain the empty site for Phase 4 in five to eight years and an environmentally safe and landscaped site.


Recycle Heating System Goals:

  • Boilers; pipes, valves, and fittings; insulation; pipe trench covers; boiler-feed pump and receive set; air-handling unit; exhaust fan; sheet metal and registers and grilles; miscellaneous metals; louvers; and automatic control devices and plastic and copper tubing.
