Description
The control of the climatic conditions in the cult buildings; especially the mosque; proves arduous because
open doors generally and the variation of the occupants number. Indeed, air conditioning systems are not often effective.
The integration and optimization of passive solutions via the envelope can be the solution to this problem. In the present
paper, a detailed energy and environmental analysis of a Mosque building, is investigated. The dynamic simulations using
TRNSYS software are conducted under the new climatic zoning of Morocco. The effect of integrating of two alternatives
techniques such as "lightweight concrete" and "cool roof" into the Mosque building on the energy needs are evaluated and
discussed. Results obtained show that using the lightweight concrete technique with olive pomace or with cork or with
hemp leads to reduce the total annual energy need by about 9.5 % ,12.7 % , 22.5 %, respectively. Moreover, integrating the
cool roof technique by modifying the reflectance coefficient from 0.5 to 0.9, the reduction of energy demand attained 43%.
We can see that with simple passive envelope strategies, it is possible to reduce more than 50% of energy needs and
approaching the optimal comfort conditions.
