                       SIEMENS AND EMCOR FORM ALLIANCE FOR
                   BUILDING PERFORMANCE SOLUTIONS AND SERVICES

        Customers will benefit from combined expertise and specialization

BUFFALO  GROVE,  IL  and  NORWALK,  CT -  October  2,  2003 -  Siemens  Building
Technologies,  Inc.,  and  EMCOR  Facilities  Services,  Inc.,  a  wholly  owned
subsidiary  of EMCOR  Group,  Inc.  (NYSE:  EME),  have  entered into a mutually
beneficial  alliance that will benefit  customers of both companies by providing
the industry's most comprehensive offering of building performance technologies,
solutions and services.

As part of the alliance arrangement,  the parties have entered into an agreement
for EMCOR to purchase Siemens'  Facilities  Management Services ("FMS") business
in the United States. The Siemens FMS business provides  facilities  services to
single buildings and corporate campuses throughout the United States.  Financial
details of the transaction were not disclosed.

EMCOR Facilities  Services is a premiere supplier of mobile and on-site building
operations and maintenance services and facilities  management  services.  EMCOR
Facilities Services currently provides services to customers in over 850 million
square feet of space worldwide.

Siemens Building  Technologies  provides building  infrastructure  solutions for
comfort,  life safety,  security systems and energy efficiency,  optimizing both
building  performance and operating cost. The company  manufactures  and markets
building  controls,   and  fire  protection  and  security  systems  for  civic,
commercial and industrial  properties,  specializing  in education,  healthcare,
government,  and high-tech  manufacturing  facilities,  as well as  campus-style
corporate complexes.

"For customers  looking to outsource a broad range of facilities  services,  the
Siemens-EMCOR  alliance  will be able to bundle the best and most  comprehensive
solution  available,"  said Stan Kunka,  President & Chief Executive  Officer of
Siemens  Building  Technologies,  Inc. "The alliance will pool its knowledge and
expertise  in  order  to  provide  customers  with  improved  value,   increased
efficiencies and, overall better facilities performance," Kunka added.

"Customers  are looking for  strategic  partners  that can offer  single  source
facilities  solutions,"  said Frank T.  MacInnis,  Chairman and Chief  Executive
Officer  of EMCOR  Group,  Inc.  "Combining  Siemens'  broad  range of  building
technology product solutions with EMCOR's portfolio of comprehensive  facilities
services creates an end-to-end building management resource for facility owners.
In addition,  both  organizations  have strong  commitments to provide  complete
customer satisfaction."

Siemens  and EMCOR  expect  the  alliance  to open up  revenue  growth  for both
companies by  capitalizing  on each  other's  market  presence.  Siemens will be
introduced to EMCOR's customer base, and vice versa.

Kunka added,  "The  alliance  will give Siemens the  opportunity  to enhance its
"Best Total Solution"  capabilities by allowing the company to focus on its core
competency  of  providing  advanced  building  performance  technologies,  while
offering its  customers  state-of-the-art  facilities  management  services from
EMCOR."

"Both  companies  gain  a  stronger  competitive  position  as a  result  of the
alliance,"  said  EMCOR's  MacInnis.  "Together,  EMCOR  and  Siemens  will be a
powerful force in the marketplace for making buildings work for customers."
