Sustainability Report
Embodied carbon
Carbon emissions were calculated based on material quantities estimated from architectural photographs and project description (340 m² gross floor area, Bogotá). Emission factors sourced from ICE v3.0 and Ecoinvent 3.9. The existing reinforced concrete structure — ribbed slabs, columns, and stairs — was preserved entirely and excluded from the calculation. The recovered timber floor on the second level was also excluded as no new material was introduced. Materials assessed include: polished concrete floor on ground level (~180 m², pulido of existing slab — the dominant item at 59% of total); ceramic tile in checkerboard pattern for courtyard and bathrooms (~1.2 ton); dark ceramic tile on courtyard wall (~0.8 ton); porcelain tile on rooftop terrace (~1.6 ton); handmade terrazzo curved bar counter (~0.15 ton); stainless steel kitchen counter (~80 kg); painted steel mesh, railings, and interior partitions (~600 kg); OSB panel and pine structure for darts wall (~1.2 m³); lacquered MDF joinery in coral red (~0.8 m³); concrete washbasins and vanity (~0.3 m³); interior and exterior paint across full area (~340 m²); and MEP installations for commercial use. No formal LCA software was used; calculations performed manually using ICE and Ecoinvent databases.
Operational Emissions / Energy
Operational carbon estimated for a restaurant-bar with games (ping pong, darts) operating Thursday through Sunday (~208 days/year), 340 m², Bogotá. Electricity consumption estimated at ~2,500 kWh/month during active operation periods (~17,100 kWh/year equivalent), accounting for ambient and accent lighting, bar refrigeration, sound system, and kitchen equipment; Colombian grid emission factor 0.126 kg CO₂eq/kWh (UPME 2023). Gas natural estimated at ~20 m³/month during operation (~114 m³/year) for cooking; factor 2.04 kg CO₂eq/m³ (UPME). No mechanical heating or cooling — Bogotá's temperate climate eliminates HVAC demand entirely. The central courtyard with skylight provides natural ventilation and daylight reducing artificial lighting needs during daytime service. Total estimated: ~3,888 kg CO₂eq/year across 340 m².
Service and maintenance emissions
Service and maintenance emissions estimated for a commercial venue operating 4 days per week. Main maintenance cycles: polished concrete floor requires annual sealing and periodic re-polishing every 5–7 years (~0.05 kg CO₂eq/m²/year); ceramic and porcelain tile requires occasional regrouting only (~0.03 kg CO₂eq/m²/year); painted steel mesh, railings, and partitions require touch-up repainting every 4–5 years (~0.04 kg CO₂eq/m²/year); interior paint requires touch-up every 2–3 years given commercial use (~0.08 kg CO₂eq/m²/year); lacquered MDF joinery requires periodic refinishing (~0.02 kg CO₂eq/m²/year); OSB dart wall panel may require partial replacement every 8–10 years (~0.01 kg CO₂eq/m²/year); general commercial maintenance and consumables (~0.02 kg CO₂eq/m²/year). The existing concrete structure and recovered timber floor require no maintenance. Total estimated: ~85 kg CO₂eq/year across 340 m². No formal LCA software used; estimates based on ICE v3.0.
Afterlife
Adaptive reuse is the structural premise of the project. Pong 2.0 occupies a multi-story house whose reinforced concrete skeleton — ribbed slabs, columns, stairs, and rooftop terrace — was preserved entirely and reactivated without modification. The building's spatial sequence — ground floor, mezzanine, upper level, and rooftop — is a residential typology that has already proven its capacity to accommodate radically different programs. The current use as a games-restaurant venue could transition back to residential, to office space, to a cultural venue, or to a co-working environment without structural intervention. The central courtyard with its glass roof is program-neutral and adds value across any future use. The building is located in a consolidated urban neighborhood, ensuring long-term relevance regardless of programmatic changes.
The painted steel mesh panels used as interior dividers and railings are bolted modular elements that can be dismantled and reused or recycled at end of life. The OSB dart wall panel is a screwed assembly that can be fully removed and either reused or returned to the wood fiber cycle. The lacquered MDF joinery in coral red can be disassembled and repurposed. The handmade terrazzo bar counter, while fixed, is a durable element that could be carefully extracted and recirculated as a salvage piece. Ceramic and porcelain floor tiles are individually removable and reusable. The stainless steel kitchen counter is fully recyclable. The recovered timber floor on the second level has already completed one lifecycle and continues circulating — it can do so again. The reinforced concrete structure and polished concrete floor are permanent elements, but their permanence is their sustainability argument: they will outlast any renovation cycle and never generate demolition waste.
