The base case energy simulation result (Fig. 5) shows that the cooling load contributes to 53% of energy consumption in the building (AHU cooling—43%, fans—9% and pumps—1%) and the interior lighting and equipment load contributes to 17% and 31% of the total energy consumption, respectively. This clearly gives an indication
In line with GBI (2013) the objective of passive design for EE is to minimize energy consumption in buildings so that CO2 emissions are reduced. According to (Ann and Abualrejal (2015), building
However, there is a need to take more actions in order to implement national targets into the high-performance building projects. The country''s new economy-wide unconditional target is to reduce its greenhouse gas emissions by 70 per cent below its 1990 level in

The Home Energy Score is a national rating system, developed by the U.S. Department of Energy, which provides a rating of your home''s current efficiency, as well as a list of improvements and potential savings. The Score reflects the energy efficiency of a home based on the home''s structure and heating, cooling, and hot water systems.
Resonating with the concept of green buildings, strategic site planning involves harnessing natural features to enhance energy efficiency. This includes aligning structures to maximize solar gain, utilizing prevailing winds for natural ventilation, and preserving existing trees for shading. 2. Energy-Efficient Design.
Canada''s commercial building sector is a significant energy user and producer of carbon emissions. It includes a range of building types, including offices, hospitals, schools, and more. Buildings retrofitted to higher energy-efficiency standards provide multiple benefits to those who own and occupy them, including: Long-term energy and cost savings: an
