Older, inefficient commercial rooftop unit (RTU) air conditioning systems are common and can waste from $1,000 to $3,700 per unit annually, depending on the building size and type. By replacing or retrofitting them, you can save money, improve your energy efficiency, make your building more comfortable, and help the environment. The Advanced RTU Campaign (ARC) encourages commercial building owners and operators to replace their old RTUs with more efficient units or to retrofit their RTUs with advanced controls in order to take advantage of these benefits.
You can learn more at www.advancedrtu.org, including case studies, energy savings calculator, utility rebates, building awards, and more.
Evolution and Infinity 2-stage A/C now only require 2-wires
Running extra wires to a 2-stage condensing unit has long been a challenge in retro-fit situations. If the wiring situation looks challenging, contractors might not even offer the homeowner the more comfortable multi-stage option. Or worse, it is offered and sold, but then the install crew gets to work and hits some road blocks which make the labor more costly and hurts contractor profit.
Those days are pretty much behind us now. TEC’s inventory of Bryant Evolution and Carrier Infinity communicating condensing units now includes 2-stage units that only Continue reading →
To further cement Chicago’s status as a center for sustainability and green jobs, Mayor Rahm Emanuel today introduced an ordinance that would require the city’s largest buildings to benchmark their energy use and authorize the City to disclose the energy efficiency for these buildings publicly. Below are the highlights as described by Benny Skelton of ASHRAE. The Mayor’s press release can read at the link below. Continue reading →
Check out this article in the ACHR News if you want a glimpse of the future of energy efficiency (see link below). I will warn you that it is not sexy new HVAC products for you to sell. It is all about the building functioning as a complete system. It is written jointly by Dick Lord of Carrier (he is a Carrier Fellow with 40 years at Carrier engineering), Drake Erbe of Airxhange (he is the alpha dog there) and Robert Wilkins of Danfoss (former president of the company). They are part of a new AHRI committee setup to focus on the energy efficiency of systems as a whole, not specific products. Continue reading →
