The construction of the project started in 2008, initiated by a large group of real estate developers in cooperation with the Westin hotel chain. The resort harbors 620 rooms on 23 floors, 6 auditoriums, 4 restaurants, a club house, shopping areas, swimming pools and a furnace room. Both indoor and outdoor solutions could be met with a total of 10 miles of our Flexalen pre-insulated piping system for domestic heating and cooling, and 11 mileskm of our technical ThermaSmart Pro insulation for the chilled water lines. The construction of the project was finalized in 2010.
The design and installation took place in 4 phases:
1. Network design and installation preparation for optimal routes, significantly saving time for phase 2
2. Implementation of pre-assembled and pre-insulated pipe sections of 25m instead of 5 conventional linear meters, assembled on the spot. This was made possible by the flexibility and light weight of the material
3. Connections on-site to system units
4. Final pressure testing of the system
The goal for the project developer was not only to establish a top class hotel in Panama, but also to develop a leading example for innovative green building in the industry. A smart, innovative and sustainable solution for the resort's energy needs, would stand key in ensuring a full-proof guarantee to that goal. Through earlier small-scale projects, the project development group got to identify Thermaflex as an ideal solutions provider for their needs.
Due to the reliance on unspecialized labor for the network installation and operation, ease of installation and low operating cost were also key considerations for this reference project, and further secured by our technical support.
Since the end of the project in 2010, Westin's thermal energy networks have been operating smoothly, without any need for repair or corrections. With all factors taken into account, including material, installation and operational costs, investment reached a similar level compared to that of traditional steel/PUR systems, yet with a much stronger return in savings and headache-free ownership. Return temperatures of the chilled water turned out much lower than previously accounted for in the engineering design. This means less chiller capacity is needed, resulting in even more energy savings than expected.
