What is Ecowatt® ?

Soler & Palau offers a range of products that effectively and efficiently meet the needs of the customer. S&P’s products can virtually be found in any commercial or residential application, ranging from innovative, quiet and reliable room ventilators to large diameter, high capacity exhaust systems designed for critical applications in some of the world’s harshest environments. As our engineers strive to manufacture the most efficient products in the industry, our R&D department is working to make these products energy efficient and safe for the environment.

To emphasize this movement in technological advancements, S&P has developed the Ecowatt® standard to classify energy-efficient products that use Electronically Commutated (EC) or Direct Current (DC) motors. Models that fall under this standard have a certified performance through AMCA (Air Movement & Control Association International, Inc.) or HVI (Home Ventilating Institute). If the products designed for residential applications the model must be ENERGY STAR® qualified.

Without these certifications or qualifications, the product is not Ecowatt® compliant and will not display the Ecowatt® symbol on the side of the fan.

LEED for Homes

What is LEED for Homes?

LEED, or Leadership in Energy & Environmental Design, is a green building certification program that recognizes best-in-class building strategies and practices. To receive LEED certification, building projects satisfy prerequisites and earn points to achieve different levels of certification. Prerequisites and credits differ for each rating system, and teams choose the best fit for their project.

How can S&P products help with my LEED for Homes Points?

S&P can help with the following requirements and points to gain LEED v4 Certification: Homes:

Required: Ventilation

Single Family Homes: Meet all of the following criteria for local exhaust and outdoor air ventilation including the requirements of ASHRAE 62.2 – 2010, sections 4, 5 and 7 and Section 1504.4 of the 2009 International Residential Code (IRC).

Multifamily Homes: Design and install a whole-unit ventilation system for each dwelling unit that complies with the requirements of ASHRAE Standard 62.2 – 2010 (with errata) or local equivalent, whichever is more stringent, and all local exhaust requirements for Single Family section, above.

Enhanced Ventilation (Possible 3pts)

OPTION 1: Enhanced Local Exhaust (1pt)

Use one of the following strategies in every bathroom with a shower, bathtub, or spa (i.e., half-baths are exempt) to control the use of the local exhaust fan:

  • an occupancy sensor;
  • an automatic humidistat controller;
  • a continuously operating exhaust fan; or
  • a delay timer that operates the fan for at least 20 minutes.

S&P's BEST Solution: PCD110XM - PC with DC Motor & Motion Sensing Grille.


OPTION 2: Enhanced Whole-House Ventilation (2pts)

Install a balanced whole-house ventilation system (not just exhaust only or supply only) that meets the minimum ventilation requirements of ASHRAE Standard 62.2 – 2010, Sections 4 and 7, or local equivalent whichever is more stringent. Program the system such that it does not exceed the standard's requirements by more than 10%.

For multifamily buildings, meet the above requirements for all in-unit residential spaces in both options 1 and 2.

S&P's BEST Solution: TD-MIXVENT Fan with FT622 ASHRAE 62.2 Control.

Enhanced Garage Pollutant Protection (Possible 1pt)

CASE 1: Single Family

OPTION 1: Exhaust Fan in Garage (1pt)

Install in the garage an exhaust fan that is rated at least 75 CFM (35 liters per second) and meets ENERGY STAR® CFM/W performance requirements.

The fan must vent directly to the outdoors and have an automatic timer control linked to an occupant sensor, a light switch, a garage door opening-closing mechanism, a carbon monoxide sensor that turns on the fan when ambient CO levels reach 35 ppm or equivalent. The timer must be set to provide at least three air changes each time the fan is turned on.

Projects that earn the EPA Indoor airPLUS label automatically meet the requirements of Option 1.

CASE 2: Multi-Family

OPTION 1: Exhaust Fan in Multicar Garage (1pt)

For a garage that accommodates more than three cars, follow the requirements in ASHRAE 62.1–2010. Exhaust the garage sufficiently to create negative pressure concerning adjacent spaces with the doors to the garage closed. Provide self-closing doors and deck-to-deck partitions or a hard lid ceiling. The pressure differential with the surrounding areas must be at least 5 Pascals (Pa) (0.02 inches of water gauge) when all doors are closed. The exhaust fan may either run continuously or on a carbon monoxide sensor that turns on the fan when ambient CO levels reach 35 PPM.


OPTION 2: Exhaust Fan in Small Garage (1pt)

For a garage that accommodates one, two, or three cars, install an exhaust fan that meets ENERGY STAR minimum efficacy levels (CFM/W); direct-exhaust fans must be 100 CFM (47 liters per second) or higher, and ducted exhaust fans must be 130 CFM (61 liters per second) or higher.

The fan must either run continuously or have an automatic timer control linked to an occupant sensor, a light switch, a garage door opening-closing mechanism, a carbon monoxide sensor that turns on the fan when ambient CO levels reach 35 ppm or equivalent. Any timer must be set to provide at least three air changes each time the fan is turned on.

S&P's BEST Solution: PC fan with PCIAQS or PCD110XIAQS fan installed in Garage.

Acoustic Comfort (Possible 1pt)

These requirements only apply to "acoustically sensitive" rooms, such as bedrooms, dining rooms, living rooms, and studies. ("Acoustically insensitive" rooms include bathrooms, kitchens, and hallways.) Projects may also implement the measures throughout the entire home.

OPTION 1: Prescriptive noise reduction methods

Meet all of the following requirements:

  1. Mechanical systems must meet the following criteria:
    • Continuous ventilation fans shall have a maximum sound rating of 0.7 sones. Intermittent fans shall have a maximum sound rating of 1.5 sones unless their maximum rated airflow exceeds 400 CFM. HVAC air handlers and remote-mounted fans are exempted if the fans are mounted outside the habitable spaces, bathrooms, and hallways and if there are at least 4 feet of ductwork between the fan and the intake grill.
    • Meet the following best-practice HVAC installation measures:
      • Ducts are securely attached (no loose connections between sections of ductwork).
      • The fan housing is securely anchored.
      • The damper flap closes fully, with no visible airspaces around the flap.
    • For projects that are less than a half a mile away from any significant noise source such as (but not limited to) aircraft over-flights, highways, trains, and industry, exterior assemblies must include:
      • Exterior windows and doors must have a minimum STC rating of 35.
      • All exterior wall penetrations must be sealed with an acoustical sealant, and/or otherwise treated for sound control (e.g., lined elbows on vents, lined outer ducts where feasible).
    • Attached single family homes and multi-family homes must also meet the following:
      • Party walls must have a minimum STC rating of 55.
      • All party wall penetrations must be sealed with acoustical sealant
      • Floor/ceiling assemblies must have a minimum STC and IIC rating of 55.


OPTION 2: Performance-based compliance requirements

Meet all of the following. The tested levels must be met in the acoustically sensitive room that is considered the worst case condition.

  1. The maximum background noise level in the home or unit due to exterior noise sources cannot exceed 40 dBA, based on the peak hour Leq.
  2. The maximum background noise level in the home or unit due to interior noise sources (HVAC systems, lighting, and other building services operating simultaneously) shall not exceed 40 dBA, based on the peak Leq.
  3. Party walls must have a minimum NIC rating of 50.
  4. Floor-ceiling assemblies between units must have a minimum NIC and FIIC rating of 50.
