On April 18th, the Aldo Leopold Legacy Center received Platinum LEED certification from the U.S. Green Building Council. After testing and evaluation, it was determined that the Legacy Center is the highest ranked LEED cerfified building - in the world. Indirect, high efficiency lighting, a grid tied, 39.6 kW solar electric (PV) system is connected to the main distribution panel for the building, inttelligent dimming techniques and many other efficiency measures help reduce the electrical load of the building.

The UW Heliport requires six different electrical systems, all with separate conduit runs and some with different voltages. It is mandatory that the entire heliport area be energized at all times. In the event of a power shutoff, emergency power is also required. Because an existing penthouse was chosen as a site for the heliport, it was necessary to demolish and relocate vital electrical services. "Feeder" conduit runs were then pulled up through chases to the two-level Heliport facility. Crews worked six day weeks and multiple shifts to meet the the completion date of October 1st, 2006. Temporary power for the tower crane was also critical, as storage space was at an absolute premium. Once primary power was in place, crews wired for the variety of systems; emergency power, critical power, life safety, data, controls, hangar doors, safeties and fire alarms. Fuel pumping for the aircraft was a critical issue. With the main fuel supply located on the ground floor, much attention was given to adequately pumping fuel to dipsensers located in the hangar area.

The St. Mary's Hospital Expansion includes roughly $9.5 million of new electrical work. This project includes a power house addition, a new in-patient facility and new parking ramp. Work began in 2006 and will finish in spring of 2007. The completed power house contains four 2 megawatt, 4.16 kilovolt Caterpillar generators and a completely revamped medium voltage power distribution system. The new generators provide emergency power and can deliver enough electricity to power the entire St. Mary's hospital for days on end if necessary. The primary power comes into the building at 13.8 kilovolts to a 6 section S&C metal clad switchboard installed by H&H Electric, then gets transformed by MG&E to 4.16 kilovolts and sent back to General Electric switchgear in the power plant that H&H Electric also installed. The General Electric equipment includes medium voltage switches and paralleling gear and is made up of some 25 pieces of gear all field installed and wired by H&H Electric. The power house when completed will be state of the art and will give the Hospital the ability to load shed and provide reliable backup emergency power well into the future.

H&H Electric worked with both Findorff & Sons and Krupp Construction on the state of the art Nolen Shores Condominium tower for developer Lance McGrath. H&H installed all the electrical in the twelve story fifty six condominium tower. Two stories of underground parking were included in the project. The condominiums are each custom designed in layout, cabinetry and especially lighting and appliances. Lighting types run the gamut from low voltage monorail to pendants and recessed cans and chandeliers. Heated towel racks, radiant floor electric heat and other custom electrical requests were not uncommon. Primary power is three phase 208 volt. H&H also handled security which includes key card access, close circuit television, voice/data and fire alarm systems. Each condominium has the backbone wiring for DSL, hi-speed, satellite and wireless. Cable providers can simply tie into the basic package already in place for each unit.

H&H Electric installed all the electrical, voice/data and fire alarm systems for this new, four story addition to the business school. The fire alarm system was upgraded and is now entirely housed in the new wing. State of the art lighting controls for classrooms, voice/data for offices and a large UPS (uninterrupted power supply) were some of the many features in this project. The project was completed in August of 2008.
