BUILDING PERFORMANCE SIMULATION: WHAT’S IN THE BLACK BOX & HOW DO I GET MY BIM DATA THERE? – DRURY B. CRAWLEY, PH.D.

One of the inter-disciplinary events that IBPSA-USA, Houston & USGBC Texas Gulf Coast Chapter organized this month was Dr. Dru Crawley’s talk on Building Performance Simulation. ASHRAE Houston Chapter also jointly sponsored this meeting with Association of Energy Engineers .

Over the last 50 years, Building Simulation has evolved into a powerful tool. It allows easy comparison of the energy and environmental performance of many hundreds of design or retrofit options. Dr. Dru Crawley from Bentley Systems, touched upon the development of energy simulation tools since 1970s and briefed about various algorithms being currently used in Energy & Lighting/Daylighting Simulation software. He talked at length about where the BIM industry is headed towards integration of Modeled & Real data, and various technological advances that the building-industry is undergoing right now.

The meeting was held at Green Building Resource Center.

BEHIND THE F.A.C.E. – Façade Analysis by Comparisons and Evaluations in the urban context

Slide1

Mili Kyropoulou from HKS Line presented at the October meeting. The objective of the her study was the investigation of the residential urban multi-storey building, with reference to the Greek “polykatoikias”, the most typical typology in the Greek urban environment. The talk focused on the examination of the features and the potential of the façade element of the multi-storey buildings, as this is the physical boundary between the interior and the exterior conditions and for this typology is almost the only exposed surface of each unit. The comparative indicators of the assessment in this study were the daylight availability (illuminance) and the thermal performance (heating and cooling loads), which lead to a continuous attempt of establishing a balance between the two. Image 1
