Overview

Econometric panel study finds power recuperation systems reduce electricity use and operating costs in ultra-low-energy buildings, indicating strong lifecycle financial feasibility.

Key Points

Evaluate the causal impact and economic feasibility of power recuperation systems on energy consumption, operating expenditures, and financial returns in ultra-low-energy buildings across China.
Constructed a panel dataset of ultra-low-energy residential and commercial buildings across 30 Chinese provincial-level regions from 2015 to 2025.
Applied a propensity-score-matched difference-in-differences model with building and year fixed effects, supplemented by system generalized method of moments estimation.
Assessed economic feasibility via annual energy-cost savings, discounted payback period, net present value, internal rate of return, and sensitivity analyses.
Power recuperation systems significantly decreased electricity consumption and annual operating costs across ultra-low-energy buildings.
Financial returns were highest in high-rise commercial buildings, regions with higher electricity tariffs (eastern and northern cities), and facilities with intensive elevator and ventilation usage.
Economic returns proved sensitive to upfront capital costs and utilization intensity, though most installations remained financially viable across medium- and long-term operating horizons.
