Evaluation de l'impact des toitures blanches sur les charges énergétiques d'immeubles.

Assessing the impacts of white roofs on building energy loads.

Auteurs : HILDEBRANDT E. W., BOS W., MOORE R.

Résumé

The impact of white roof coatings on energy loads in three non residential buildings in Sacramento was assessed using a new approach to statistical analysis. Hourly metered loads were designed to isolate the effects of white roof coatings on building cooling loads from changes in cooling loads due to variations in outdoor temperatures. Results indicate that the effect of solar insolation levels on cooling energy consumption was significantly decreased after the application of white roofs in all three buildings. Savings estimates based on this approach range from 17 to 39% of total cooling loads.
