The Hangzhou Daming Government Building archive records a tall office facade organized around warm brown panel fields, repeated dark windows and a central glazed strip. One original photograph supports that visual reading. The 2016 LOPO page also lists a terracotta rainscreen panel, item F5030238 and a nominal size of 500 × 1000 × 30 mm.

Those entries make a useful named-project reference, but they do not form an as-built specification. No independent record found in this audit links the English project name to an owner, exact address or project team. The historical page also provides no quantity, year, drawings or test evidence.

What the Archive Establishes

A current enquiry should use dated terracotta panel documentation for the exact product and market. The old item and size can help locate archive records but should not be copied into drawings or procurement schedules without confirmation.

Reading the Office Elevation

The photograph presents two panel-clad wings framing a vertically emphasized glazed zone. Dark window openings repeat in a close grid across the warm elevations. The panel colour is not perfectly uniform: lighter and darker brown areas create subtle variation without breaking the overall composition. At roof level and around the glazed strip, the grid changes to accommodate different facade elements.

This is visual evidence only. The image cannot confirm which surfaces use F5030238, whether the nominal 500 × 1000 mm face is installed horizontally or vertically, or how cuts occur around windows. Perspective, joints and resolution make image-based measurement unreliable.

Coordinate Panels, Windows and Glazing

An office facade with frequent openings needs a clear setting-out strategy. Panel joints, window heads, sills, jambs and intermediate floor lines should relate to agreed datums. The central glazed zone introduces another trade, separate tolerances and perimeter weathering details. Corners at the tower edges and transitions at the roof also require drawn solutions rather than generic product details.

The architect should control the visible grid and colour distribution. The facade engineer should define actions, support zones, movement, water management and required evidence. Suppliers and installers should respond with coordinated shop drawings, calculations, samples and inspection records within their contractual scopes. LOPO’s panel installation guide can organize questions but does not reveal the method used on this building.

The Photograph Does Not Prove a Rainscreen

Although the archive calls the product a rainscreen panel, a finished elevation does not show the cavity, rails, brackets, anchors, insulation, membrane, flashings or cavity barriers behind it. It also cannot prove structural resistance, fire behaviour, water performance, thermal performance or durability. These require project-specific design documents, calculations, classification reports and tests where the responsible authority requires them.

The ventilated facade engineering guide describes the type of submission trail a current project may need. It must be adapted to actual loads, substrate, height, exposure, jurisdiction and selected assembly.

Colour planning also needs its own record. A single approved swatch cannot describe the distribution visible across a tall elevation. The project team should agree a reference range, viewing distance, blend method and rejection process, then review the installed work by defined zones. Glazing colour and reflected sky will change the perceived contrast, so facade reviews should consider solid and transparent areas together rather than approve each trade in isolation.

Evidence Required for a Comparable Office Project

• Confirm the building, elevations, scope and responsible project parties.
• Issue current product data, dimensions, tolerances and colour samples.
• Coordinate window, glazing, corner, parapet and base interfaces.
• Define structural, fire, water and movement acceptance criteria.
• Record mock-up reviews, tests, installation checks and replacements.

Reference imagery is useful for intent, especially the balance between warm solid walls and cool glazing. It cannot replace a technical brief. More documented facade precedents are available in the terracotta project gallery, each with its own evidence limits.

Claims Removed From the Old Copy

The former article relied on poetic language about warmth, nature, harmony and architectural spirit. It also described natural materials as environmental and low-carbon without defining a product, declaration, system boundary or project calculation. The revised case keeps observable composition and historic fields while removing claims that the source cannot demonstrate.

Frequently Asked Questions

Is this verified as a government-owned building?

No independent record reviewed here establishes the owner. Retain Hangzhou Daming Government Building as the historical English project name unless a primary project document confirms it.

Was F5030238 definitely installed at 500 × 1000 × 30 mm?

That is the archive entry, not an as-built schedule. Confirm the code, face dimensions, thickness, orientation, tolerances and quantity through project records.

Does the photo confirm a ventilated rainscreen?

No. It shows the exterior appearance only. The cavity, supports, weather layers and fire-stopping arrangements are concealed.

Can the panel grid be measured from the photograph?

Not reliably. Perspective and image resolution distort scale. Use coordinated elevations, setting-out drawings and approved samples.

Request a Current Office-Facade Review

Provide the project location, elevations, openings, colour intent, substrate, performance criteria and delivery programme. Contact LOPO with those documents so any panel discussion is tied to a verifiable scope rather than this archive image alone.
