For several months, SES has been conducting site visits to Choate’s Carr Hall Admissions Center project, reviewing the installation of thermal and moisture control products at the slabs, foundation walls, and underground garage. During our last visit, vertical construction was underway, and we’re looking forward to the start of MEP work! We’re privileged to provide both envelope and MEP commissioning services for this project, allowing us to follow the construction from initial sitework through to post-occupancy. #commissioning #buildingcommissioning

SES was in Boston to review the ongoing MEP progress at the apartments at 288 Harrison. We love seeing the progress made on the final installations. The contractors have done some great work! SES witnessed some preliminary balancing readings in the apartment spaces—this is an important aspect to ensure system energy efficiency is optimized. We're looking forward to functional testing to help ensure a healthy and efficient building for the future residents! #commissioning #buildingcommissioning

SES was in New York conducting functional testing of MEP equipment for the apartments at 3 Westchester Park Drive. We are excited to provide our commissioning skills to help ensure efficient systems for the owner and future residents! #commissioning #buildingcommissioning

SES visited the Brooklyn VA Medical Center to witness boiler safety device testing. This testing is a crucial portion of turnover for all VA boiler plants and involves systematically testing and verifying that safety devices are set at the proper settings. It’s important that the design team include all isolation valves, drain ports and pressure gauges in the piping layouts so that the testing process can be followed. Following successful completion of the testing, the boiler will then undergo 30-day performance verification testing, during which the system will need to operate without faults or trips for 30 days before turning it over to the owner. #commissioning #buildingcommissioning

The Wesleyan Integrative Arts Lab building is nearly enclosed! This historical renovation project will include a large performance space, movement studio, drawing studios and more. SES is excited to provide envelope and MEP commissioning services for this unique project. #commissioning #buildingcommissioning #historicalrenovation

These air handling unit (AHU) casings look almost identical, however, looks can be deceiving! During retro-commissioning investigations, opening up each access door to confirm the equipment and accessories installed in each unit is essential. One unit is a mixed-air AHU, which brings in a combination of outside air and return air, heating and cooling it as needed to supply the space. The other unit is a 100% outside air AHU, which can either be passed through a hot water coil to heat the air or bypass the coil with a face-bypass damper combination.

SES was on site at what will be the future Cromwell Middle School. It is always a breath of fresh air to visit such a clean job site. Good work by Newfield Construction and their team for prioritizing safety and maintaining such a clean environment! #cleanjobsite #construction #commissioning #buildingcommissioning

A key aspect of envelope commissioning is reviewing the foundation waterproofing. The membrane seen in this photo prevents moisture from entering the building through the concrete. Exposure to moisture can eventually damage the foundation of the building and cause mold and mildew to develop on the interior. During our site visits, our Cx team verifies that this membrane is continuous and free from any damage to ensure it'll do its job well for years to come! #commissioning #buildingcommissioning #buildingenvelope #foundationwaterproofing

During a recent retro-commissioning effort, several air handling units were discovered to have outside air dampers that had failed open. Although it is crucial for air handling units to bring in outside air, exceeding the minimum requirements when outside air conditions are not conducive for economizer mode can lead to higher-than-expected energy bills, humid space conditions, and more. #commissioning #buildingcommissioning #existingbuildingcommissioning #ebcx #retrocommissioning #rcx

Here we go! SES visited the site of the new ACES Wintergreen Inter-District Magnet for the initial MEP and envelope site visit. Depending on the progress of the project, during our first visit, we typically review items such as the building’s air vapor barrier (AVB) system, HVAC systems, domestic hot water systems, lighting controls, and more. The contractors have done some excellent work so far! #commissioning #buildingcommissioning
