Formerly known as Clayton Village, the new Maddaugh Road Elementary school has the capacity for 525 Grade 1-7 students and 80 Kindergarteners, with a neighbourhood learning centre. Spaces include a variety of Classrooms, Ancillary spaces, Administration spaces, Breakout areas, Learning Commons, Multi-Purpose area, Project Areas and a Gymnasium. The NLC area provides enhanced gymnasium facilities, a school gathering space, and two additional classrooms. It was built to LEED® NC 2004 Gold equivalent standards and maximized the use of wood.

Project Scope:

• The mechanical design comprised a cost effective, decentralized system that offers a high level of energy efficiency with a simple, easy to understand layout. The amount of fresh air being delivered to the classrooms is tightly controlled through CO2 and occupancy sensors.
• The decentralized Unit Ventilators offer quiet and draft free ventilation to the classrooms with minimal moving parts and a long service life.
• A roof mounted heat recovery air to water heat pump offers an energy efficient source of hot and chilled water. This unit can move energy from the hot loop to the chilled loop and vice-versa during periods of simultaneous building heating and cooling loads. During cold weather, backup heating is provided by high efficiency natural gas boilers.
• Hot and chilled water distribution throughout the school is delivered via variable speed pumps modulating to meet the building load.

Key outcomes:

• Simplicity and Reliability;
• Ability to service with minimal disruption to ongoing school operations;
• Decentralized system where operation of one smaller portion of the school/building does not require running large central systems serving the remainder of the building;
• High level of occupant comfort with reduced drafts and consistent temperature control;
• High level of energy efficiency.
