Utilizing building energy simulation to improve process load heat reclamation for a multi-sport athletics venue

Large, multi-use sports and recreational facilities provide a unique, yet challenging, opportunity for energy conservation due to their large process loads. The proposed paper describes the use of building simulation to aid in mechanical system and architectural design to improve heat recovery from process heat generation to satisfy building loads. The focus of this study is a recreational facility that consists of an NHL-size ice arena, 8-sheet curling rink, a gymnasium, change and restrooms, offices, library, fitness studios, a large glazed atrium, as well as 50 metre lap, leisure, outdoo

Casthouse Ventilation Design for the Production of Air-Cooled Aluminium Sows

The Aluminerie Alouette Inc. (AAI) smelter in northern Quebec, Canada recently completed a major plant expansion that includes a new casthouse for the continuous production of low-profile, air-cooled aluminium sows. The radiation and convection heat release of 15 MW to the workplace from the aluminium metal solidification and cooling is significantly higher than that experienced in the traditional water-cooled casting process where the majority of the heat is removed by the cooling water.
