Turnkey solutions; Measurable results

SEM’s advanced energy and water management solutions are implemented by organisations and businesses throughout South Africa to reduce costs and optimise energy and water usage. Our solutions are proven to help reduce energy and water consumption and our AMR systems offer real-time monitoring in commercial and industrial operations of all sizes.

SEM's turnkey approach means that we implement complete systems that are able to offer results right from the start.

SEM's process really worked. They delivered exactly what they set out to do.
We continue to save daily on our utility costs.

Benefits of turnkey solutions

There are multiple advantages to our turnkey approach, which has been honed over many years of field experience.

SEM is able to assess your site in a single survey, identifying prime areas for optimisation and making recommendations that can be integrated into any existing building. Our team, together with expert subcontractors, integrates solutions that are immediately ready for use upon installation.

SEM ensures that the most effective cost-saving equipment is selected for every site, and that it is implemented without disruption to regular operations. With a proven track record on both large and small projects, and experience in working on sites of all sizes, we're able to implement solutions with greater efficiency and less time wastage.

SEM has the advantage of not being linked to any specific brand, and can thus select the most appropriate solution for each site.

As accredited Green Star Professionals, we can assist in obtaining Green Star Credits ranging from surveys required for the new Existing Building Performance Tool to Independent Commissioning services as required for the MAN-4 credit. These services contribute to the optimal operation of the building.

We are an Eskom-registered ESCo company, have CIDB gradings of 5EB, 5CE, 4ME and 3SOand are a Level 1 BBBEE Contributor.
