Services: Commercial Alterations 

BarrierEnergy is your one-stop-shop for consulting, referrals, and assessments for your commercial alterations project. We will help you stay on schedule, on budget, and compliant with energy standards.

Title 24 Compliance

Title 24 of the California Energy Commission (CEC) outlines energy efficiency standards for new, altered, and existing buildings in the state of California. The HERS index gives buildings a score based on their energy efficiency, on a 0-150 scale. California requires a mandatory energy score, as well as mandatory compliance measures. Optional upgrades and tests can translate into compliance points. For more information, visit the CEC website.

 

Commercial Alterations

Commercial projects that fall under Title 24 commercial codes include multi-family dwelling units, storefronts, offices, and any common indoor space that is non-residential. Alterations consist of additions, remodels, and change-outs and energy efficiency upgrades. A change-out is when someone replaces a component of the HVAC system, such as the ductwork or the furnace. Any of these alterations require a HERS test by California state law. The technician must certify that the installation has remained within energy efficiency guidelines. 

NRCC

In the beginning of a commercial construction project, permits must be applied for. To gain approval, Nonresidential Certificates of Compliance must verify that the plan-set for construction are within California Energy Code guidelines.

Solar Ready Area

More Info
Currently, all new or altered buildings in the state of California must have sufficient space for solar panel installation. A Solar Ready Area is a large, relatively flat empty space on the roof, which could potentially hold solar panels.

This law was created as a precursor for PV solar requirements. Most new buildings will need to have solar panels installed unless they meet certain exemptions. Learn more on our page about Solar Ready Area and Solar Panels.

Lighting

More Info
In order to meet energy efficiency guidelines, lighting systems must adhere to certain requirements. For example, using energy-efficient bulbs, such as LED, will allow you to stay within the allotted power allowance. Another method of improving efficiency is to install lighting controls such as light sensors, automatic shut-off schedules, and so on.

Nonresidential lighting verifications cover indoor, outdoor, and sign lighting. Learn more about JA8 Lighting.

Commercial Refrigeration

Garage Exhaust

More Info
Garage exhaust fans prevent air from being trapped in a commercial garage. They allow air circulation, which removes toxic vehicle fumes. While designing your garage, an expert technician can approve your plan-set, based upon their calculations.

In addition to ventilation system acceptance testing, garages are also required to maintain proper air pressure and carbon dioxide sensors. Reach out to an expert at BarrierEnergy today. We will fill out and submit all necessary paperwork from the California Energy Commission.

Fan Power Consumptions

More Info
Commercial buildings must meet energy standards, which dictate the power consumption of air conditioning fans. The Air Movement and Control Association (AMCA) developed the Fan Power Index as a universal measurement to monitor these standards. Fan efficiency is affected by electrical input horsepower, motors, fan size and so on.

At BarrierEnergy, our certified HERS Raters are certifieid to calculate these complex equations. That way, your project will pass the compliance phase.

Elevators & Moving Walkways

More Info
It is mandatory that escalators and moving walkways have an automatic speed control and a variable speed motor. They also must have sensors for approaching pedestrians. In addition, elevators are closed spaces and thusly must have proper lighting and ventilation.

Here is yet another form the California Energy Commission wants filled out properly and signed by a field technician. This is because the state must monitor and approve your building plans. A HERS Rater is licensed to calculate these variables. If your commercial project includes moving walkways, you can trust our team to guide you through energy code standards.

Process Boilers

More Info
Boilers use the combustion of fossil fuels to create steam, which is harnessed to produce thermal energy. A process boiler must have a capacity of at least 300,000 BTUs (British thermal units) per hour, while serving a process. A process refers to any activity that is related to HVACR (heating, ventiliation, air conditioning, refridgeration).

The process boilers compliance document contains a record of the equipment’s specific description. It must be filled out and approved by a licenesed technician in mathematical detail.

Outdoor Air

More Info
The outdoor air certificate of acceptance is granted after a technician performs a variable air volume systems test. Basically, the airflow of supply vents will be tested to confirm there is adequate outdoor ventilation for the HVAC system. Supply vents provide a building with fresh, temperature controlled air.  Outdoor air circulates inside a building to maintain air quality. There should be sufficient airflow, but still controlled.

At this stage, a field technician will be verifying the functionality of the outdoor air systems including supply fans, heat pumps and ductwork. Other compliance criteria consists of correct thermostat placement and programming, and so on.

Indoor Airflow

More Info
All ducts have a return vent to counter-balance supply vents. Supply vents expel temperature controlled air into a building. Opposingly, the return vent pulls air from inside the room to take it back to the furnace or conditioner. This keeps air moving cyclically and evenly throughout a building.

It is our job to verify the return vent has been installed properly and the airflow levels match current standards. Certified HERS Raters will hook a flow hood up to the return vent in order to read its airflow in cubic ft per minute. They will also test the return vents’ air economizer controls, demand control ventilation, and fan variable flow controls.

AC Systems

More Info
Testing the AC system after installation is important. This involves simulating its’ cooling features to make sure it can handle the buildings load capacity efficienctly. The system should be able to change modes depending on set schedules throughout the day. A licensed technician will also check the supply fan and condensing unit. An AC system should be able to regulate temperature in a building effectively.

Energy Management Systems

More Info
An Energy Management Control System (EMCS) is a computerized program that coordinates the energy consumption of a building through components such as HVAC, lighting, and water heating. By monitoring system loads and environmental factors in real-time, it automatically adjusts itself to maximize energy savings.

The purpose of acceptance testing is to confirm the EMCS is operating correctly, in concession with energy efficiency standards.

Garage Exhaust

More Info
Garage exhaust fans prevent air from being trapped in a commercial garage. They allow air circulation, which is important to remove toxic vehicle fumes.
