F. White Contracting Company's Mechanical Division to replace the riser isolation valves, riser piping and fan coil units (FCUs) in the "D" Building.  The HVAC renovation included the phased demolition of the existing riser piping and FCUs, installation of a new brazed copper riser system, and the installation and wiring of new fan coil units. The project required extensive and, by its nature, disruptive work to be performed within privately owned condominium units.  J. F.white's scheduling team provided the Owner a detailed and easy to follow schedule that was used to inform the tenants about outages and coordinate the work within the units amon the various trades.  J. F. White's skilled tradesman and project team provided the manpower and planning to meet the needs of Brook House Condominiums for a successful completion.

Home » Community » Mechanicals Fan coils and return air from framing voids I'm a home inspector working in the Chicago area and recently I was tasked with inspecting a three-bedroom condo on an upper floor of a newly constructed high-rise building downtown. The fan coil units are located inside alcoves behind hinged metal fire rated access doors. They are in an interior framing void space approximately 3 ft.² and about 10 feet tall. The return air grilles are located in the ceiling but there is no ductwork; when the fan coil air handler kicks on it draws air through the return air grille, swirls it through framing voids in the walls and ceilings (some of which are visible and some of which are not), draws it across the standard 1 inch "rock catcher" filter and then across the coil. Now, common sense tells me that this is just plain idiotic and I recall reading one of Uncle Joe's articles a while back which echoed my sentiments on the subject. In response to my report, the builder says it's standard procedure and was approved by our fair city during the design process.

I still find it completely idiotic. I'm looking for some type of standard or code which this installation contravenes. Your help is greatly appreciated.

Historical Homes For Sale In Piqua Ohio Questions about one inline exhaust fan serving two bathrooms Cristalla, an elegant 22-story residential tower located in downtown Seattle, generated a buzz as a residence that was “raising the bar” even before construction began.

This was in part due to the fact that the design team intended to incorporate in the entrance to Cristalla the domed glass ceiling and terra-cotta base of the Crystal Pool. This saltwater bathing house once occupied the same site as Cristalla almost a hundred years earlier. The fusion of the sleek look of the new construction and the Italian Renaissance-inspired look of the Crystal Pool was breathtaking. The project management knew that the discerning buyers of Seattle would expect a sophisticated HVAC system in their luxury condos. By using SureFlow®, the mechanical design team was able to accommodate the need for a superior HVAC system that provided optimum comfort while meeting the budget. Given the publicity touting Cristalla as raising the bar for downtown residences, the challenge was to find an HVAC system that would also raise the bar. This system needed to have 4-pipe performance and allow the design team to deliver a first-class project in every detail, all while coming in on budget.

A SureFlow hydronic system was the perfect fit. This type of system had the lowest operating cost, lowest maintenance cost, and the lowest sound levels in the rooms – with a competitive first cost. By using the SureFlow system, the number of penetrations needed to accommodate 4-pipe performance was reduced by 40 percent – a tangible plus, since the owner wanted to reduce floor-to-floor fire-safe and waterproof seals. The vertical piping design allows the horizontal units to be located for easy access in multiple floor plans. PROBLEM:  A new construction project that required minimal piping penetrations. SOLUTION: The SureFlow system allowed for 2-pipes to deliver 4-pipe performance – thus cutting the required core drilling by 60%. PROBLEM: Design required flexibility in the location of the mechanical equipment. SOLUTION: Unlike a rigid DX system, SureFlow is inherently flexible during the construction phase – even with floor plan changes. PROBLEM:  The need to maximize sellable floor space and to get the highest sell price per square foot.

SOLUTION: SureFlow units install horizontally or vertically and do not have a compressor – keeping them out of sight and out of mind. The use of SureFlow in the Cristalla project eliminated over 5,000 feet of return risers. This reduced the required hangers and supports, expansion compensation, insulation and fittings. The SureFlow design improves the performance of each fan coil unit by guaranteeing the proper flow while maintaining the highest flexibility for change during the project’s construction or in future renovations. The SureFlow Hi-Performance series units accommodate ductwork; a necessity for a construction project of this caliber. Each unit included a three-speed fan switch to adjust the airflow after the ductwork was installed, which allows for changes in air delivery to meet the required performance. Each fan coil is controlled by a digital, 7-day programmable thermostat. “SureFlow allowed us to meet all the loads and model the performance for the contractor with the SureFlow Loop Simulator software;
