Douglas Drewniak

BEPIT Manager

A building performance engineer, Douglas leads Bioregional’s drive for truly sustainable, energy efficient buildings.

A practical expert with most of his career spent on construction sites, Douglas’ role is to manage and deliver a brand-new service for housebuilders known as the Building Energy Performance Improvement Toolkit (BEPIT).

BEPIT is a response to the energy performance gap prevalent in new residential housing. It was developed together with industry as part of a four-year research project funded by Innovate UK. As part of the BEPIT service, Douglas is embedded in a site’s construction delivery team, where he monitors processes that are critical to energy efficiency throughout the design, procurement and construction stages. He also applies carefully crafted learning modules in a ‘toolbox talk fashion’ alongside workshops, site inspection and building performance testing. This all helps housebuilders reduce risk and improve quality.  

Prior to joining Bioregional in 2013, Douglas worked on a range of housing projects in Germany and the UK. His previous role was site analyst for Stewart Milne on AIMC4, pioneering the volume production of low carbon homes. Douglas graduated from Edinburgh Napier University with a first class Honours degree in civil engineering before going on to collect an MSc in Advanced Structural Engineering. His BSc dissertation focused on sustainable housing design, while his later studies looked at how to improve offsite timber frame systems.

In his spare time Douglas enjoys building things (proud owner of a man shed/pub in his garden), hiking and swimming in ice cold Scottish lochs, and relaxing with a brew and a good book.
