Construction Phase HVAC Controls Coordination

Don’t be the team that finishes the building and then wonders why nobody brought the airflow measuring station.

November 1, 2013

HVAC systems continue to be the most challenging part of a new construction project to get right the first time, and the most challenging parts of the HVAC systems are their controls. I believe there are two root causes.

Patient Rooms: CFD For Better IAQ

Can a location of air return affect the flow path of airborne pathogens in a patient room? Use simulations to manage the variables and improve the design in a space that is no room for error.

Air is the primary carrier of heat, moisture, contaminants, and airborne pathogens in patient rooms, isolation rooms, and operating rooms.

Chiller Retrofit: The Attraction Of Magnetic Bearings

With multiple expansions and projects, a DC-area hospital also had to plan for cooling that could keep up with developing demands and spaces.

UVC lights the way to cleaner air, energy savings at FL office tower

November 1, 2013

In real estate it’s all about location. But in south Florida, where beautiful views and gorgeous weather are the norm, building owners need to find ways to differentiate themselves and bring in tenants.

Energy recovery earns high marks at RI career academy

November 1, 2013

Designing a new high school to be 40% more efficient than ASHRAE 90.1 – 2001 energy requirements is a lofty goal.

NIBS offers commissioning symposium

November 1, 2013

Commissioning is a valuable tool, but according to the National Institute of Building Sciences, there is a great deal confusion as to what commissioning is, who is qualified to perform it, and the different types of commissioning agents.

Building To Grid — AKA B2G

When it comes to the Smart Grid, are you prepared? Consider two design strategies to connect buildings to the available benefits.

You’ve heard a lot of talk about the deployment of the Smart Grid. Most of the initial smart grid deployments are focused on the de-ployment of smart meters that enable utilities to gather usage information in near real time — or what they call Automated Meter Infrastructure (AMI).

Calculated With Care: Ventilation in Health Care Systems

A Mississippi clinic needed above-average design on a budget. The equipment was nothing unusual. However, creativity and attention to detail uncovered opportunities to fine-tune the design and exceed ventilation benchmarks for less.

Engineers’ daily challenges include calculations for outside air, supply air, and return or exhaust air flows — all while balancing mandated code requirements with owners’ expectations for performance, equipment first-cost, and future energy costs.
