Location: Dallas, TX

Project Description:

Rader Engineering provided mechanical design services for this high end condominium project located in Dallas Texas. The mechanical systems consisted of a total of 8 water-to-air heat pumps (totaling 31 tons), which were connected to the building’s existing boiler/ tower loop. The units were all located in mechanical closets remote from the rooms that they served, and all ductwork was lined with 1-1/2” of internal duct insulation, to minimize any acoustical transmission issues associated with the heat pumps. All supply and return air was via slot diffusers integrated into the elaborate ceilings. Steam humidification units were incorporated into the HVAC system to meet the Owner’s humidity needs. The entire system was controlled by a Direct Digital Control (DDC) system integrated into the Home Automation System.

High Aspen Ranch Residence

Location: Garfield County, CO

Project Description:

Rader Engineering provided mechanical engineering services for this high-end custom home in High Aspen Ranch. The project consisted of two phases (two buildings) that were connected by a connector bridge. The home is heated and cooled by a ground source heat pump (GSHP) system connected to 40 vertical boreholes, each 250’ deep. In total, there are four 10 ton water-to-water GSHPs in the project, totaling 40 tons. Special attention was paid to properly attenuating sound generated by the mechanical systems, as this was a high priority for the Owners. Sound mitigating strategies include vibration isolators for fans, piping and ductwork as well as Variable Frequency Drives

(VFDs) for optimal fan coil control. The home is equipped with a sophisticated DDC control system. Multiple air-to-air heat exchangers are utilized to provide efficient and balanced fresh air exchange in the home. Both phases include a whole house exhaust fan used for general ventilation and for free nighttime cooling. Special exhaust and ventilation systems were designed for the woodworking shop, fabrication and finishing rooms. All of the garages are provided with exhaust ventilation for improved indoor air quality and health. Domestic hot water is generated by GSHP preheat ing as well as by high efficiency gas-fired condensing boilers.

Wildcat Ranch

mwcms on August 6, 2024

Location: Snowmass Village, CO

Description

Rader Engineering provided mechanical and geoexchange engineering services for this energy efficient ranch home in Wildcat Ranch. The project implements many sustainable and energy efficient technologies including Solar PV and GeoExchange. The geoexchange system consists of 4 stainless steel heat exchanger plates, set on 24” high elevated platform stands, set on the bottom of the onsite pond. The pond heat exchangers serve two ground source heat pumps (GSHP). Each GSHP is a 10-ton water-to-water unit that provides heating water to the radiant floors during the winter and chilled water to the fan coils during the summer. The heat pumps also serve limited exterior snowmelt, controlled on an automatic snowmelt sensor.

Due to the long horizontal piping length from the home to the pond, premium efficiency pumps and motors were used to circulate the closed loop geoexchange system. A methanol/ water solution was utilized for its superior heat transfer capabilities and low viscosity. Other energy efficient systems worth noting are the desuperheaters incorporated into the GSHPs which capture waste heat at the compressors and utilize this heat for domestic hot water preheating. Also, there is an energy recovery ventilator (ERV) for efficient and balanced delivery of fresh outdoor air to the home.
