Warm-up with Tilt-up

Feb 17, 2015

As we endure the continued bone-chilling cold weather, who can’t help but think about the additional energy it will take to keep our schools warm. These cold days can make it tough on school boards who are balancing student and staff comfort with growing energy costs.

Although energy consumption is impacted by a number of variables, one of the biggest contributing factors is the construction assembly of the structure itself. Insulated concrete tilt-up panels provide one of ― if not the― most energy efficient building envelopes available today. Since most new construction is already using higher quality air and energy delivery systems that means the “shell” provides the greatest opportunity for saving energy when designing structures.

SiteCast tilt-up insulated concrete panels offer an overall energy and life cycle performance that is typically 30% more energy efficient than traditional high quality wall assemblies.

Here’s how:

  • For starters, SiteCast tilt-up panels are constructed with two layers of concrete, continuously separated with a 3” (or greater) closed cell rigid insulation core, providing an assembly which has all the properties and characteristics of a high performance wall assembly. 
  • SiteCast tilt-up building envelopes provide the most effective continuous insulation including an edge-to-edge and foundation-to-roof, uninterrupted rigid insulation layer that has no thermal penetrations through this valuable veneer which exceeds all Canadian energy code standards. 
  • While the three-layer panels deliver insulation to resist the effects of temperature changes in the climate, the interior layer of concrete (load bearing) provides thermal massing properties that stabalize the interior air temperature buffering swings and thereby eliminating the surges in demand on a school’s energy systems. As a result, your HVAC equipment does not have to work as hard or as long to maintain a comfortable environment. Savvy designers will harness this concept and reduce the energy systems capacity, which in turn will be a capital savings to the school board. (Incidentally, concrete walls also offer sound-deadening and abusive resistant properties as well.)

The net benefit to the overall system is the temperature and interior temperature consistency or comfort level which provides the students a higher learning environment.

While people have come to think speed when they hear tilt-up, a growing number of school boards, like Conseil des écoles publiques de l’Est de l’Ontario (CEPEO), have realized the benefits of using insulated tilt-up exterior wall panels to help reduce their annual operating energy costs.
