Sustainability in DC – July Meeting 2013

Wednesday July 31st, 2013, 6-8pm

Mr. Indrajeet Viswanathan, Energy Consultant at the DC SEU

and

Patti Boyd, Manager of Engineering of the DC Sustainable Energy Utility

“How to integrate programs such as DC SEU with broader sustainability efforts in DC”

Mr. Indrajeet Viswanathan

As an Energy Consultant at the DC SEU, he identifies, advocates for and advises on energy efficiency improvements in new construction and existing commercial and institutional buildings and facilities. He also works towards delivering market-based services to maximize the penetration of cost-effective and energy-efficient improvements within the District of Columbia, by supporting the implementation through energy and financial analysis.

Ms. Patti Boyd

As the Manager of Engineering for DC SEU, Patti develops and proactively implements the engineering team’s strategic plans and initiatives. Additionally, while supervising and providing mentorship to engineering and operational staff, she identifies, advocates for and advises on energy efficiency improvements in commercial, institutional and multifamily buildings and facilities within the District of Columbia.

This presentation will be followed by a couple of case studies by our members on simulation work they have done on buildings in the DC area. This will included a brief talk by Roger Chang on the DC Green Construction Code.

The floor will then be opened to discussion and questions on Sustainability in DC and simulation issues that arise from the participants work.

Location:

IBPSA NCC Quarterly Meeting

INFILTRATION AND SIMULATION – MODELING AIR TIGHTNESS IN BUILDING

Wednesday April 17th, 2013, 6 – 7:30pm

Lisa Ng Lisa Ng, Mechanical Engineer at NIST

“Consideration of Envelope Airtightness in Modelling Commercial Building Energy Consumption”

Lisa graduated from Drexel University with a B. S. in Architectural Engineering, concentration on HVAC systems. While at Drexel, she completed co-ops with a construction management, a project management, and an HVAC design/consultation firm. After graduation, she lived and worked in Taipei, Taiwan for two years for an architect as a mechanical engineer.

In 2005, Lisa began her Ph.D. work at Drexel University, focusing her work on indoor air quality and sensor placement. In 2010, Lisa graduated with a Ph. D. in Civil Engineering with a thesis titled “Framework for the Utilization of Forward and Inverse Airflow Models in Systematic Sensor System Design for Indoor Air”.

After graduation, Lisa completed a one year post-doc at the National Institute of Standards and Technology (NIST). Currently, she is a mechanical engineer in the IAQ and Ventilation Group at the NIST in Gaithersburg, MD. Her work includes airflow, IAQ, and energy simulations, as well as IAQ sampling in a net zero house.
