Why Are Buildings So Important?
• World total energy consumption is expected to increase as high as 50 percent in less than a decade.
• Buildings are responsible for 38% of total energy use –that figure increases to up to 70% in some countries.
40% of U.S. Primary Energy Consumption

Building Energy Efficiency
“…is the single most important opportunity for reducing greenhouse gas emissions” (2007-2008 ASHRAE President Kent Peterson)
“…is the “fastest-growing success story of the last 50 years” (American Council for an Energy Efficient Economy)

ASHRAE Standards
• ASHRAE had existing standards for residential and commercial buildings, for residential and commercial ventilation requirements and others
![Page 7: ASHRAE 90.2 Kuwait - agu.edu.bh Day/3/Walid.pdfASHRAE 90.2 –Kuwait ... • Informative Appendix B—HVAC and Ventilation Systems. 2.) Scope. ... 55 60 65 70 80 90 100 110 120 130](https://reader030.vdocument.in/reader030/viewer/2022021416/5ab0d1327f8b9a00728b86e5/html5/thumbnails/7.jpg)
Standard 90.2
The purpose of this standard is to provide minimum requirements for the energy-efficient design of residential buildings.

Standard 90.1• Recently established by U.S.
Department of Energy as the commercial building reference standard for state building energy codes.
• States must certify compliance by October 2013
• DOE determined 18.5% less building energy use than 2007 standard
• It was determined to be 30% less building energy use than 2004 standard

Green Building Standard
• Published in January 2010• Serves as benchmark for
sustainable green buildings – does not apply to all buildings
• Addresses energy, impact on the atmosphere, sustainable sites, water use, materials and resources and IEQ

ASHRAE 90.2 KuwaitEnergy-Efficient Design of Low-Rise
Residential Buildings in KuwaitCase Study
![Page 13: ASHRAE 90.2 Kuwait - agu.edu.bh Day/3/Walid.pdfASHRAE 90.2 –Kuwait ... • Informative Appendix B—HVAC and Ventilation Systems. 2.) Scope. ... 55 60 65 70 80 90 100 110 120 130](https://reader030.vdocument.in/reader030/viewer/2022021416/5ab0d1327f8b9a00728b86e5/html5/thumbnails/13.jpg)
The Kuwaiti Government Needed:
• A comprehensive residential building energy efficiency standard in response to a growing residential energy need
• A standard that covered the building design and all of its components, including air conditioning and ventilation air
![Page 14: ASHRAE 90.2 Kuwait - agu.edu.bh Day/3/Walid.pdfASHRAE 90.2 –Kuwait ... • Informative Appendix B—HVAC and Ventilation Systems. 2.) Scope. ... 55 60 65 70 80 90 100 110 120 130](https://reader030.vdocument.in/reader030/viewer/2022021416/5ab0d1327f8b9a00728b86e5/html5/thumbnails/14.jpg)
Requirements
The ministry requested a standard for use with residential houses
•Written in simple code language
•To be developed within six months
•To be a stand alone standard
![Page 15: ASHRAE 90.2 Kuwait - agu.edu.bh Day/3/Walid.pdfASHRAE 90.2 –Kuwait ... • Informative Appendix B—HVAC and Ventilation Systems. 2.) Scope. ... 55 60 65 70 80 90 100 110 120 130](https://reader030.vdocument.in/reader030/viewer/2022021416/5ab0d1327f8b9a00728b86e5/html5/thumbnails/15.jpg)
The Solution
1. In late 2009, a group of ASHRAE members from the United States and Kuwait University came together to create a version of ASHRAE Standard 90.2-2007 to take into account the differences between existing standards and the needs of Kuwait
2. Existing Kuwaiti building and energy requirement related documents were reviewed, and an outline of the requirements for the new standard was developed
![Page 16: ASHRAE 90.2 Kuwait - agu.edu.bh Day/3/Walid.pdfASHRAE 90.2 –Kuwait ... • Informative Appendix B—HVAC and Ventilation Systems. 2.) Scope. ... 55 60 65 70 80 90 100 110 120 130](https://reader030.vdocument.in/reader030/viewer/2022021416/5ab0d1327f8b9a00728b86e5/html5/thumbnails/16.jpg)
3. The appropriate sections of the various existing standards were identified and pulled together to form an outline of a 90.2 Kuwait standard
4. The outline was then further tailored and filled in to meet the needs of the Kuwait residential construction market
5. Specific new materials were developed for the Kuwait standard, such as the requirement for creating a positive pressure environment to control the infiltration of dust
The Solution

The Solution
6. Upon completion of a first public review draft, it was presented to, and discussed with, a group of Ministry of Energy and Water engineers
![Page 18: ASHRAE 90.2 Kuwait - agu.edu.bh Day/3/Walid.pdfASHRAE 90.2 –Kuwait ... • Informative Appendix B—HVAC and Ventilation Systems. 2.) Scope. ... 55 60 65 70 80 90 100 110 120 130](https://reader030.vdocument.in/reader030/viewer/2022021416/5ab0d1327f8b9a00728b86e5/html5/thumbnails/18.jpg)
The Solution
7. Their input was then factored into a revision of the draft standard, and it was again presented to, and discussed with, a second group of Ministry of Energy and Water engineers
8. Input from the second review was then factored into the final ASHRAE Standard 90.2 Kuwait
![Page 19: ASHRAE 90.2 Kuwait - agu.edu.bh Day/3/Walid.pdfASHRAE 90.2 –Kuwait ... • Informative Appendix B—HVAC and Ventilation Systems. 2.) Scope. ... 55 60 65 70 80 90 100 110 120 130](https://reader030.vdocument.in/reader030/viewer/2022021416/5ab0d1327f8b9a00728b86e5/html5/thumbnails/19.jpg)
The Results
• ASHRAE Standard 90.2 Kuwait was then published in March 2010, and subsequently presented to the Kuwait Ministry of Energy and Water
• The project was so successful that the ministry is considering more cooperation with ASHRAE on modifying the school and hospital design guidelines developed earlier by ASHRAE to suit Kuwait.”
