Energy Efficiency Building Retrofits


Rogier has been at the forefront of a strategy which treats energy retrofits as capital investments, not operational savings. His focus has been on retrofits that improve asset values and achieve 80+% GHG reductions. Approached this way, issues such as life-cycle planning, capital budgeting, and an economically sound and systematic approach to prioritizing competing solutions under constraints are emphasized. With a background in economics, and project development, Rogier creates value by bringing long industry experience to bear on these challenges.

As president of DaBx Demand Side Solutions Rogier focuses on strategic consulting on the economics of renewable energy, as well as providing technological solutions. This includes system purchasing and project management for the integration of renewable energy solutions primarily in existing residential buildings. It is this methodology that enables a paradigm shift from energy consumption to energy production.

This approach optimizes financial risk management pertaining to energy, and achieves the optimal balance of maximal property values and minimal GHG-emissions.
