Energy Performance vs Capital Cost
Apply ISO 50001 energy review discipline to eliminate demand loads first, then right-size mechanical systems so efficiency gains offset additional capital cost.

Business Context
High-performance envelopes, efficient HVAC systems, advanced controls, renewable energy, and energy recovery can reduce building consumption and operating expenses. However, some measures require higher initial investment, creating pressure on development budgets.
Real Estate & Construction TRIZ Resolution
Energy demand should first be reduced through passive and low-cost measures. Reduced loads can then permit smaller mechanical and electrical systems, allowing efficiency investments to offset capital requirements elsewhere. Expensive technologies should be applied only where simpler measures cannot achieve the required performance.
Applicable TRIZ Principles
Principle 2 – Taking Out removes avoidable energy loads before increasing system efficiency.
Principle 3 – Local Quality concentrates high-performance measures where they produce the greatest benefit.
Principle 22 – Blessing in Disguise converts reduced energy demand into smaller infrastructure requirements.
Expected Outcome
Lower energy consumption
Controlled capital expenditure
Reduced operating costs
Improved lifecycle economics
Decision Indicators
Early indicators include:
Energy measures are evaluated independently from equipment sizing.
Mechanical systems remain unchanged after envelope loads are reduced.
Expensive active systems compensate for inefficient passive design.
Efficiency targets depend primarily on additional equipment.
Capital constraints lead to removal of high-value energy measures.
