50,000 sq foot expansion / upgrade of the School Districts' advanced learning center comprised of:
-3,000 sq foot retail bakery and restaurant
-5,000 sq foot teaching kitchen
-2,000 sq foot demonstration kitchen
-Robotics labs, advanced science, and electronics
-Solar heated greenhouse, and banking center
This building is an educational facility that will allow for student interaction with the mechanical systems that serve their environment. With this goal in mind, the mechanical systems will demonstrate the most common HVAC systems that employed throughout the School District. The building will be served by two system types: 1) water source heat pumps for a portion of the building and packaged rooftop VAV with series fan powered VAV terminals with hot water reheat. The actual division of the systems is based on programmed usage of various spaces within the building.
The water source heat pump system is based on roof mounted units with 100% outdoor air economizers. The additional heat required will be added to the condenser water loop with a plate and frame heat exchanger interface with the building’s hydronic hot water system. A small closed circuit cooling tower handles the heat rejection from the condenser loop.
Packaged rooftop VAV with series fan powered VAV terminal reheat units serve a portion of the building. The roof unit has a full air side economizer with powered exhaust and a VFD driven supply fan. There are three kitchen areas: Bakery, Teaching Kitchen, and Demostration Kitchen with various Type 1 and 2 exhaust hoods with dedicated make up air systems. The make up air units are evaporative cooling assisted and indirect gas fired heating.
Controls and Energy Strategies that work.
Three merging trends began to make designing with legacy control stragegies impossible: 1) the trend toward more factory mounted controls and less field installed components; which has led to finger pointing between vendors and control installation companies, as to what is provided and by whom? 2) the incorporation of more smart devices and communication protocols (see url) and 3) the desire to use more sophisticated control strategies that incorporate “smart” energy savings such as automated demand response and LEED building control strategies and features. Technical Designs set out to find a better method to manage this problem for our Clients. The result was the ability to write the building control software, test this software off line, hand this software off to the installing contractor and manage the commissioning process over the web from anywhere in the world. Using VMware and web tools, the engineers at Technical Designs that conceived how the building was to perform, now verify this in real time. Just as designing in 3D does not allow you to “fake” it, no longer will the engineer be allow to throw a few half baked ideas at the control contractor expecting everything to magically work.×
Integrated Project Delivery
Technical Designs became interested early on in the use of Integrated Project Delivery (IPD) . IPD is simply the use of web based tools that support consultants with specific expertise to collaborate on a single design model that exists in the cloud where team members have direct access in real time. This process could be applied to any type of project: from designing a circuit board to movie production. Technical Designs focused on what knowledge we bring to the process and developed the tools and skills necessary to support the building design process within the construction industry.×
