Climate Risk Analyses for the Real Estate Industry: Process and Benefits
5 min readThe effects of climate change are having an ever-increasing impact on the real estate industry, which will affect buildings and their functions in the future. The predicted risks are far-reaching, from increased cooling demand for buildings caused by rising temperatures to damage caused by flooding due to increased and more intense rainfall events, and even…
Pump Cavitation and Its Effects in Closed Loop Systems
2 min readAs we know, the presence of air pockets in the closed loop pipe system, like we routinely find in hydronic heating and cooling systems, lowers its overall system performance. Air pathways through such a system are via many pathways such as through pipe joints, valves, leaky coils, etc. So, it is important to properly flush…

It involves some honest conversations and collaborative decision-making. Often, it takes training a committee of colleagues with other responsibilities who have never done this…
Using CFD to Optimize Thermal Comfort in a Distribution Center
7 min readWith the growth of online shopping and logistics, the demand for warehouses and distribution centers has increased over the past decades. Applying effective heating, ventilation, and air-conditioning (HVAC) strategies in these buildings is important to maintain thermally safe comfortable indoor environments. With large volumes, shifting usage patterns, and sensitive equipment, computational fluid dynamics (CFD) can…
BEPS – Understanding the Performance Pathway (Part 4)
4 min readIf you own or operate a building in Washington, DC, you should be paying attention to the District’s Building Energy Performance Standards (BEPS). This policy requires buildings to meet a minimum level of energy performance. If your building does not meet that requirement, you must take steps to reduce building energy use or face financial…
Beyond Scorecards: The Intersection of ESG, Sustainability, and Building Performance
5 min readWhat do LEED checklists, energy and daylight models, commissioning, and ESG reports have in common? They all support green building certification, strong building performance, and ESG goals simultaneously! Green building certifications like LEED, WELL, Fitwel, and BREEAM, along with building performance strategies such as modeling and commissioning, play a crucial role in supporting ESG goals…
Beat the Heat: Smart Strategies for a Comfortable Indoor Environment in the Summer
7 min readAs temperatures rise during the summer months, so too do indoor temperatures. The aim of summer thermal protection is to protect buildings, rooms, and therefore users from high outdoor temperatures and the resulting heat build-up from solar radiation. The indoor environment should be perceived as pleasant and comfortable without being too damp or dry. Summer…
