ASHRAE 90.1-2010

New Requirements for Building Owners are Here

Effective June 30, 2015, the State of Florida added a sweeping set of new mandatory requirements to the Florida Building Code.  Known as ASHRAE 90.1, these requirements affect every building’s lighting system, requiring higher efficiency standards than ever before.

Known as ‘lighting power allowances’,  these standards are expressed in maximum watts/ sq. ft.In other words, more efficient lighting is becoming a necessity. Technologies such as LED are more suitable for illuminating the same space with less energy.

Furthermore, the use of automatic controls (occupancy/ vacancy sensors, daylight sensors, etc) are now required.

The compliance process can be complex and frustrating for a building owner or facility manager, but Accurate Technologies is ready to help.  We can navigate you through the technical jargon of ASHRAE 90.1, and the many product choices available.

The Upside

The good news is that the initial investment will pay for itself. The goal of ASHRAE 90.1 is energy reduction, and that means electric bill reduction.  There will be a return on your investment, and you will be left with a more valuable piece of real estate and more free money in your operating budget.

Some of the possible benefits include:

  • Lower electrical bills
  • Reduced load on your electrical system
  • Reduced load on your HVAC system
  • Automatic testing and reporting of all emergency fixtures and battery backups (you just hand the fire inspector the latest test, stored as a file in the system)
  • Collection and recording of energy usage data for more accurate business planning
  • Integration of your lighting with HVAC, security camera, telecom and environmental systems
  • Real time monitoring and event triggered alerts, informing the owner of unauthorized activity
  • Automatic reporting of failed light fixtures (just forward the report to your maintenance department as a work order)
  • Generation of statistical reports for equipment performanceIMG_20160303_0617281

 

Summary of ASHRAE 90.1-2010

Design, Scope, Administrative

There are different prescribed methods to determine the maximum lighting power allowances. They are listed by the Lighting Controls Association here.  At Accurate Technologies, we have found these power densities easy to meet with our high efficiency solutions. ASHRAE LPA

Lighting Controls

According to the Lighting Controls Association, the following requirements are now legally in force:

• automatic shutoff of indoor and outdoor lighting when not in use;
• automatic lighting shutoff now required in buildings <5,000 sq.ft. unless specifically exempted;
• automatic lighting shutoff requirements of code now required for lamp plus ballast retrofits impacting 10+% of the connected lighting load;
• occupancy sensors required for a broader range of applications
• manual-ON or auto-ON to 50% operation required for automatic controls;
• multilevel lighting in spaces using manual space controls;
• automatic multilevel lighting in certain stairwell, parking garage and other spaces;
• automatic daylight harvesting control;
• power credits providing additional lighting power allowances as an incentive for using advanced control strategies;
• functional testing of controls; and
• documentation requirements including a control narrative and maintenance schedule.

New (2010) (section 9.4.1)
•All spaces require a control device for lighting that must be manual on OR auto on to 50% or less

Previous (2007)
•Enclosed spaces required a control for general lighting that could be either manual or automatic

Changes
•Lighting must have a manual on control OR automatic with the fixtures wired so no more than 50% of the general lighting comes on


LIGHTING SHUTOFF REQUIREMENTS

New (2010) (section 9.4.1.1)
•Interior lighting in buildings shall have an automatic control to shut off lighting in all spaces

Previous (2007)
•Required only for Classrooms / Conference and Meeting Rooms / Employee Lunch and Break Rooms

Changes
•Sensors and Time Switches are the only products that can accomplish this and comply with the new requirements.


SPACE CONTROL REQUIREMENTS

New (2010) (section 9.4.1.2)

•Each space enclosed by ceiling height partitions will have at least one independent control device within that space.
•Lighting will have at least one independent control step between 30% – 70% in addition to all off.
•A sensor or time switch must shut off all lighting in the space within 30 minutes of vacancy.


New (2010)
Spaces that require automatic shutoff of lighting within 30 minutes after vacancy
•Classrooms / Lecture Halls
•Conference / Meeting / Training Rooms
•Employee lunch and break rooms
•Storage and Supply rooms between 50 & 1000 sq. ft.
•Copier & Printer Rooms
•Office spaces up to 250sq. ft.
•Rest Rooms / Dressing / Fitting Rooms / Locker Rooms


REDUCTION OF LIGHT LEVELS
New (2010)
•Enclosed spaces must have the ability to reduce the lighting by 30-70% in addition to turning all lighting off.

Previous (2007)
•Not previously included

Changes
•Lighting controls and/or the power wiring must allow for a 30-70% reduction in light levels and provide a means to shut lighting off


DAYLIGHTING CONTROL REQUIREMENTS
New (2010) (section 9.4.1.4 / 9.4.1.5)
•Enclosed spaces with open sides of 250 sq. ft. or greater or all areas 900 sq. ft. or greater with top lighting must have multilevel daylight control Previous

(2007)
•Previously not included

Changes
•Controls must automatically adjust the lighting in the defined space. This will include spaces with windows and skylights


RECEPTACLE CONTROL REQUIREMENTS
New (2010) (section 8.4.2)
•Private offices / Open offices, and Computer Classrooms must have 50% of receptacles shut off automatically

Previous (2007)
•Previously not included

Changes
•Plug loads must now be incorporated into the occupancy controls to shut off when certain areas are unoccupied


PARKING GARAGE CONTROL REQUIREMENTS
New (2010) (section 9.4.1.3)
•Lighting in garages must automatically shut off / reduce by 30% minimum of the connected power within 30 minutes of vacancy / automatic daylighting control is required for luminaires within 6m of an open sided parking structure (40%).

Previous (2007)
•Previously not included

Changes
•Basically parking garages will now have the same requirements as indoor spaces


EXTERIOR LIGHTING CONTROL REQUIREMENTS
New (2010) (section 9.4.1.7)
•Lighting must be turned off during daylight hours / Lighting must be controlled during the night to reduce levels or turn off – depending on it’s purpose
Previous (2007)
•Lighting must be turned off during the day / control must be provided through photocell, time switch, or astronomical time clock

Changes
•Exterior lighting will now need to shut off or reduce levels part way through the night
