We'd like to transition to doing energy efficient renovations in multi-unit buildings (condos/offices) - any advice?

I would start by identifying the property management companies/developers responsible for your target market. Once you know who is responsible for the upkeep, you could hold a monthly meeting where you invite the decision makers for these companies to a local conference room, or your office to update them on energy efficient trends in their space.

Breakfast meetings are always a good idea. Your vendors should be on board to sponsor the event or provide co-op to help with funding. If you can get a speaker to come in from Hanley Wood, or another relevant source, it would be beneficial as well. This way, the attendees are listening to a 3rd party, but you are there to facilitate any follow up correspondence and hopefully generate a few solid leads.

Hope this helps.

Start a relationship with vendors who carry quality Energy Star rated products and try to educate and introduce those products to your customers and your team. A lot of clients do not know that they can receive tax benefits and reduce their utility costs by upgrading to energy efficient appliances and windows. Even changing clear glass to low-e glass helps.

We are about to start a 199 unit complex and will be performing mostly air infiltration service on all receptacles. Since the windows were all installed without foam sealer between the window frame and building framing, the maintenance crews will remove all window moldings in advance of our arrival. We found these formerly unseen leaks with a infrared thermal view camera! My website has a newsletter signup that will explain many lesser known tips, especially with respect to the receptacle and light switch voids. For the double hung windows, I like to clean the surfaces where the window closes down and place a foam seal along the bottom that takes out the backlash of a worn out lock assembly. Roll foam comes in different sizes - use the size that just allows the lock to close tightly. www.DoctorEnergySmart.com has the smartest solutions. These frugal upgrades should be done before spending on “energy-efficient” HVAC equipment and windows, etc.
