How Can My UAE Business Meet ASHRAE 90.1 Requirements for Electrical Power and Lighting?

Quick Summary

• A detailed look at what the ASHRAE 90.1 standard i.
• What your business needs to do to meet the electrical power and lighting standards highlighted in ASHRAE 90.1.

Energy efficiency has become one of the most important objectives for businesses all over the world, and the United Arab Emirates are no different in this regard. Major cities like Dubai and Abu Dhabi have been pushing towards more sustainable and green business models, and one of the best ways to measure how they are doing is the ASHRAE 90.1.

The ASHRAE 90.1 Standard is a global standard for energy efficiency in buildings. Whether you’re constructing a new facility or retrofitting an existing one, understanding how this standard applies particularly to electrical power and lighting systems is essential for compliance, cost savings, and future readiness.

What is ASHRAE 90.1?

So what does ashrae stand for? 

Officially known as Energy Standard for Buildings Except Low-Rise Residential Buildings, ashrae 90.1 is a widely adopted guideline developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers. It outlines minimum energy efficiency requirements for building design and operation

The UAE is one of the hottest countries in the world, and at the same time, a major commercial hub that requires a lot of energy usage 24/7. This makes having a standard like the ahsrea 90.1 even more important, and several local authorities in the country have already adopted it.

Electrical Power Systems

EPSs are one of the 2 key components of ashrae standards, making it very important for businesses in the UAE to pay attention to them.

• Energy Monitoring

For any building larger than 25000 sq ft, there needs to be an energy monitoring and energy management system present that can monitor electricity usage across major end uses. A major benefit for businesses operating in the UAE is the fact that most buildings will have a Building Management System that they can utilize. If that isn't present, electrical instruments can be a big help.

Other than being required by the ashrae standard, energy monitoring can also generally help the business by helping them monitor the energy usage in a building and highlighting any inefficiencies.

• Voltage Drop Limits

To meet the ashrae standard 90.1, Total voltage drop from the main service to the endpoint (including feeder and branch circuits) must not exceed 5%. For this, it is good to consult with electrical consultants early in your project to minimize voltage losses. Knowing your electrical cable suppliers in UAE is also very important as you will see if they can help you achieve the 5% benchmark.

• Transformer Efficiency

To satisfy ashrae 90.1 energy code, transformers used by the business must meet or exceed the minimum efficiency ratings specified by the standard. The best way to make sure your business meets this standard is by asking for proper documentation that checks the certification of the transformer when setting up your business.

Lighting Systems

Lighting systems are another key component that ashrae standards cover in a lot of detail.

• Interior Lighting Power Density (LPD)

Ashrae 90.1 sets limits to how much power you are allowed to use per square meter, depending on the building and room type. The best way to approach this is during the planning phase as you want to make sure you are not exceeding the power you are allowed to use before you start installing the lighting.

• Exterior Lighting Controls and Limits

Alongside interior lighting, exterior lighting of a building must also adhere to power limits and have automatic shut-off controls. Motion sensors, time scheduling, and photocells can really help in this regard, as they can help you limit unnecessary power usage.

• Functional Testing of Controls

Ashrae 90.1 requires businesses to test all lighting controls to be tested post installation to ensure they are working properly. It's a good idea to work with third-party verifiers or a commissioning authority to make sure the testing is done according to the standard, and everything is working as intended.

Compliance Pathways

There are multiple ways to make sure your business meets the different ashrae standards, and the best one for you will ultimately depend on what type of business you run and the scale of your project.

● Prescriptive Path

The prescriptive path basically requires each component to meet the specific requirements associated with it. This is generally the best approach for smaller businesses or projects

● Energy Cost Budget Method (Performance Path)

Use an energy model to show that your building performs as well as or better than a hypothetical baseline. This path is best for businesses that have very specific business plans that require unique attention.

● Appendix G (Performance Rating Method)

The ashrae 90.1 appendix g path is a detailed modeling approach that aims to meet the LEED and Estidama compliance. This path is generally the best for businesses that are aiming to achieve LEED or Estidama certificates.

How to get Started in the UAE

1. Understand Local Code Requirements

Check with Dubai Municipality, Abu Dhabi Urban Planning Council, or other emirate-level authorities to see how ASHRAE 90.1 has been adapted or supplemented locally.

2. Design with Compliance in Mind

Don’t treat energy efficiency as an afterthought. Engage MEP consultants early and include lighting and power strategy discussions during the concept stage.

3. Use Certified Products

Select lighting fixtures, transformers, and controls that come with third-party efficiency certifications (e.g., ENERGY STAR, DLC, CE marked with energy compliance).

4. Invest in Smart Controls

Use automated systems to control lighting based on occupancy, daylight, and time schedules.

5. Commission and Verify

Ensure all installed systems are tested, documented, and functioning as intended before occupancy.

6. Train Your Operations Team

Handing over a compliant building is just the beginning. Train facilities staff to use and maintain the systems effectively.

Conclusion

Overall, ashrae 90.1 is a very helpful standard for businesses all over the UAE, as it helps businesses be more energy efficient and ultimately lower their operating costs. Alongside that it is also a standard that all businesses should strive to achieve.

The best way to meet the guidelines set by the ashrae 90.1 standard is by outlining your goals in the planning stage of your business. Proper planning and getting the right equipment is a must as it helps you avoid any trouble down the line. Wiring and equipment from a brand like Go Switchgear is a must as all of the products supplied by them meet the ashrae 90.1 standard.

FAQs

Q. Is ASHRAE 90.1 mandatory in the UAE?

A. No, ASHRAE 90.1 is not mandatory in the UAE. That said, a lot of its principles are embedded in several local codes and frameworks like “Dubai Green Building Regulations” and “Abu Dhabi’s Estidama Pearl Rating System”.

Q. Do I need a building management system (BMS) to comply with ASHRAE 90.1?

A. No, a BMS is not strictly required, but it helps. ASHRAE 90.1 mandates specific controls (e.g., occupancy sensors, time scheduling, daylight dimming), which can be implemented using standalone systems or a centralized BMS for larger facilities. BMS integration is highly recommended for medium to large buildings.

Q. What kind of testing is required for lighting controls?

A. ASHRAE 90.1 requires post installation testing of all lighting systems to ensure that sensors are working properly, time scheduling shuts off lights when intended, and manual controls are working without fault.
