Projects
Toronto Public Library - Lillian H. Smith Library (HVAC Retrofit) - PRIME
Completion: January 29, 2018
Location: Toronto
The Lillian Library, part of Toronto Public Library, underwent a complete reconstruction of the boiler room. This project consisted of: conversion of building steam heating system to hot water heating, new reverse osmosis (RO) atomizing humidification system in all areas, and new water control via coil pumps and bypass valving installations. Kelson was the Prime Contractor. This project had “after hours” sheet metal work, to work around an operating library coordinating and accommodating the public in an occupied facility. This was a phased construction project by tying the glycol heating boiler first, to operate early in the heating season until the final primary boilers were online. The Lillian Library has a special collections museum of archives/books. Critical care was taken to ensure books were kept in good order and air quality controlled during renovation. High performance humidification system was installed to manage humidity levels in special collections records areas. Existing steam boilers were removed. Kelson managed the procurement process, tendering the equipment, negotiating purchase agreements and managing the shop drawing process. Installation of new boilers was phased. When heat load was minimal for the building, the smaller glycol heating boiler was installed first.
Mechanical Systems
Air Balancer & Supply Fan: The Lillian Library work consisted of complex HVAC work in an existing building in a congested downtown environment. To ensure a successful project, initial balancing and air measurements was completed before work was started – to get a baseline performance for the duct system. Necessary retrofits adding humidification, dampers, and ductwork surrounding the air handling unit supply fans was completed. Following this work, final balancing was performed on the system to confirm air flow rates met design and quality was assured.
