Bentley Acquires Hevacomp, Ltd., Expanding Portfolio of Software to Improve Performance of Buildings

Bentley Systems, Incorporated today announced that it has acquired
Hevacomp, Ltd., a Sheffield, England-based leading provider of
building services design software dedicated to improving the
performance of buildings. Included in its portfolio is software for
energy analysis, heating and cooling load calculations, pipe and duct
sizing, and electrical system design and product catalogs. Hevacomp is
at the forefront of simulation for building energy analyses,
incorporating in its offerings the EnergyPlus engine, developed by the
U.S. Department of Energy, and software certified to perform CO2
emissions calculations required under Part L of the U.K. building
regulations. Market demand for these energy analysis products is
growing rapidly in the United Kingdom due to highly aggressive
government regulations designed to reduce the country´s carbon
consumption. By adding applications to Bentley´s comprehensive
portfolio that will help architects, engineers, and low-carbon
consultants design buildings that consume less energy, have reduced
CO2 emissions, and cost less to operate, this acquisition extends the
company´s commitment to sustaining infrastructure and increasing the
inventory of "green" buildings around the world.

Commenting on this latest Bentley acquisition, CEO Greg Bentley
said, "The Hevacomp product line is an important addition to our
growing portfolio of solutions that help sustain infrastructure and
the environment. Hevacomp´s substantive analysis applications leverage
the content of the Building Information Model, incorporating rigorous
engineering and enabling infrastructure professionals and
owner-operators to improve building performance and reduce lifecycle
costs.

"On behalf of all Bentley colleagues, I welcome Hevacomp users to
the Bentley user community and the Hevacomp colleagues to the Bentley
team. We look forward to working closely with both to help drive
innovations in applications and best practices that will be
instrumental in creating the next generation of energy-efficient
buildings."

Tony Baxter, former managing director of Hevacomp and now Bentley
Building´s director of product management for building services and
energy analysis, said, "We are very pleased to become part of
Bentley´s global organization and to help support its commitment to
delivering world-class building services tools and applications.
Joining forces with Bentley is the best way to build upon Hevacomp´s
30-year track record of successfully providing a complete set of
design tools and content for building services engineers, mechanical
and sustainability engineers, and low-carbon consultants. Together, we
can extend the deployment of these solutions, along with new
innovations, worldwide."

About Hevacomp Products and Services

Hevacomp´s simulation software helps engineers and low-carbon
consultants carry out complex energy analyses to examine room heat
losses and gains, summer overheating, peak design months, overheating
frequency, and building energy. It also produces 3D external shading
graphics and internal solar penetration graphics that show moving
sunshine patches within rooms. Because the simulations can be carried
out with the same project data engineers already use for simple load
calculations, no time is lost gathering additional data, and engineers
find the analyses simple and easy to perform.

Hevacomp´s wide range of building services offerings also includes
mechanical design packages for load calculations, pipe and duct
sizing, and mechanical CAD; electrical design applications conforming
to international wiring regulations, including lighting systems design
applications and electrical CAD; plus support and training focused on
satisfying the increased technical demands on mechanical and
electrical design engineers.
