building-services

building-services is a skill for Claude Code from Abhinavbwj/Skills-Architects. It costs 74 tokens per session (11,252 once invoked), scanned A, original, MIT.

A guide to the building systems that support a building, including heating and cooling, plumbing, electricity, elevators, fire protection, and coordination between these systems and the architecture.

In plain words
What is it for?
Use it to compare HVAC options, estimate space for mechanical equipment, plan risers and plant rooms, and coordinate building services.
Why use it?
It helps architects understand how technical systems affect rooms, plant spaces, shafts, ceilings, and layouts while changes are still possible.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

building-services scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Building Services for Architects

Section 1: HVAC Systems for Architects

Mechanical ventilation, heating, and cooling systems are the single largest consumer of building volume after the primary structure. The architect's HVAC decisions at concept stage — system type, plant room location, riser positions, ceiling void depth — are largely irreversible. This section equips architects to make informed selections and understand spatial consequences.

Space Allowances: Mechanical Plant as Percentage of GFA

Building Type Mechanical Plant (% of GFA) Notes
Commercial office (air-conditioned) 5-8% Higher end for prestige/lab-grade
Commercial office (mixed-mode) 3-5% Reduced mechanical plant
Hospital / healthcare 8-12% Extensive air handling, medical gases, redundancy
Hotel 5-7% Central plant + individual room FCUs
Residential (apartments) 2-4% Minimal central plant if individual systems
Retail (shopping centre) 4-6% Anchor tenants often have own plant
School / university 3-5% Varies with ventilation strategy
Laboratory 8-15% High air-change rates, fume cupboards, specialist extract
Data centre 25-40% Cooling-dominated; massive plant requirement

System Type 1: Natural Ventilation

  • Description: Relies on wind-driven and buoyancy-driven airflow through operable windows, trickle vents, and/or ventilation shafts. No mechanical cooling. Heating by radiators, underfloor heating, or convectors.
  • Spatial impact on architecture:
    • Floor plate depth: Maximum 12-15m (single-sided ventilation 2.5x floor-to-ceiling height; cross-ventilation up to 5x)
    • No ceiling void for ductwork — 50-150mm for surface pipework/wiring only
    • No AHU plant rooms required
    • Ventilation shafts/stacks may be required for buoyancy-driven ventilation (0.5-1.5m² per stack)
    • Heating plant room: 0.5-1.0% of GFA (boiler room)
  • Energy performance: 0 kWh/m²/yr for ventilation energy (heating energy 30-60 kWh/m²/yr)
  • Noise ratings: NR 25-35 (dependent on external noise — problematic on busy roads)
  • Best-fit building types: Low-rise residential, schools (in temperate climates), low-rise offices in rural/suburban settings
  • Limitations: Cannot control humidity. Dependent on external conditions. Not suitable for deep plans, noisy sites, polluted environments, or climates with sustained temperatures above 28C.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

building-services is a skill published in the GitHub repository Abhinavbwj/Skills-Architects (285 stars, last pushed 3mo ago), licensed MIT. It adds 74 tokens to every session and 11,252 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
