THERMAL ANALYSIS & DESIGN

WS provides Thermal Analysis and Design of curtain wall and exterior cladding systems, utilizing the current version of LBNL’s THERM and WINDOW software programs. Many Specification Sections require computer simulation of enclosure systems in accordance with NFRC guidelines. WS can prepare thermal computer simulations of designs and products for project applications. Thermal Analysis is offered as a comprehensive or

A Thermal Simulation is beneficial:

• For determining thermal separator materials and positions within the extrusion assembly

• Can be used to verify a system U-Value and cold spots for condensation potentiality

• Beneficial for determining expected product thermal performance prior to die release, manufacturing & installation

A Project Specific Thermal Simulation:

• Can show expected performance and be used to prepare average wall system conductance and condensation resistance

• Adjacent substrates can be included in the modeling to show suitability and/or deficiency in the Architect’s details.

The National Fenestration Rating Council (NFRC) establishes standards for the simulation and testing of building enclosure products for thermal performance. The Lawrence Berkley National Laboratory (LBNL) wrote and maintains Therm, Window and Optic software for the NFRC. These software programs are used by the building envelope industry to validate their products meet the requirements set forth by the NFRC and building codes

DESIGN, DRAFTING & MODELING

The Department of Design, Drafting and Modeling: System design, delegated design, production design and drafting for custom or standard curtain wall systems and other building enclosures, done primarily through the expression of proposal, profile, die, shop, fabrication and as-built drawings using CAD and BIM technology, working to achieve the architect’s vision and expression for the curtain wall or enclosure of the building.

WS employs staff members with architecture, design technology and related backgrounds, who work in integrated teams with engineering, led by project managers. With this system we achieve a working design for the cladding system or curtain wall that will meet the performance criteria for the building while achieving the aesthetic goals of the architect.

PRE-SALE and POST-SALE SERVICES

• Proposal Drawings: When a client is bidding on a job, WS can create a representation of what they are bidding in order to assist them in obtaining the project. WS facilitates the client’s desire to meet the architect’s design intent, as well as providing coordination with the designer. The deliverable to the client shows the overall profile of the dies.

• Pre-Sale Drawings: WS provides systematic designs for a new custom or a modified existing curtain wall or cladding systems. This can range from a conceptual design to a complete system design package, depending upon the client’s needs and requirements. WS gives clients the ability to present design intent drawings for a design build project, offer a completed system for a particular project, or even to have as an in-house base product system. These services can be provided as part of our client’s proposal submittal package in an effort to secure the project.

• Profile Drawings: Profile Drawings are the next evolution from proposal drawings. With these WS provides solid, realistic and accurate calculations for finished dimensions, die profiles, fasteners, etc. While leaving room for minimal variation and change, the profile drawings are the virtually ‘set in stone’ set of details that the client will use once the job has been awarded. (Profile drawings may also be used during the job bid phase)

A BIM (Building Information Modeling) model for a curtain wall or building’s exterior cladding system, is a digital representation of the physical and functional characteristics of that system. The model represents the definitive and authoritative guidelines from which the construction contractors and subcontractors will build with minimal deviation.

The goal of providing a model for the enclosure system of a building is to have design issues and conflicts between facade building components worked out prior to the commencement of construction; in an effort to save time and money at all stages of the construction process. At the heart of our process is an authoritative model from which to extract the data to create a complete, accurate set of construction documents.

Using Revit* architecture software, Wheaton Sprague has the capabilities to provide Building Information Modeling for the Building Envelope.

Benefits of a BIM model prior to construction:

• Safer worksite due to more pre-assembled items coming from offsite.

• Design issues resolved prior to construction

• Onsite trade construction at a minimum

• Instant changes perpetuate throughout the drawing package as one feature is revised

• Minimized down time due to conflicts

Wheaton Sprague features the following BIM Services:

• Clash Detection Modeling to meet architect/ GC requirements for coordination between trades

• Sales & Marketing Modeling to showcase client’s product as a presentation tool to aid customer in winning projects

• Construction Modeling and Shop Drawings detailed model according to customer’s needs

• Material Take-Offs for use in material orders
