Quotes: Recipe for Disaster

Recipe for Disaster Take one owner with capital budget; separate operating budget and ignore. Add one architect and heat until steamed. Expose three or more tenders, exchange parts, and trim extraneous portions. Select thinnest and discard remainder. Remove architect, save essence. Assemble subtrades, compare and trim extraneous portions. Select thinnest. Store subtrades in dark. Collect…

The Building Enclosure Core

The Building Enclosure Core reflects a very different perspective in enclosure design.  The ‘Core’ refers to all elements of the enclosure with the exception of its exterior cladding system.  It is both physical construct as well as resilience exercise as it embodies the most critical elements of air, moisture, and thermal management. Traditionally the industry…

Open EIFS: A Resilient 100 Year Wall

Open EIFS is an Exterior Insulation and Finish System that achieves high moisture resilience through increased drying capacity and redundant, yet practical, safeguards.  When implemented holistically, this assembly is both durable and high-performing. The concept builds upon research originally conducted by DOE’s Oak Ridge National Laboratory, which demonstrated high moisture performance in EIFS configured with…

Quotes: Dew Point Analysis vs. Hygrothermal Simulation

On Steady State/Dew Point Assessment (Glaser Method): BS EN ISO 13788:2002 Section 6.1 This standard gives calculation methods for: a) The internal surface temperature of a building component or building element below which mould growth is likely, given the internal temperature and relative humidity – the method can also be used to assess the risk…

Extreme Climatic Events

Extreme Climatic Events Provide Important Insights For Resilient Design

Extreme climatic conditions are those falling in the upper or lower tenth percentile of the local period of record. North American hygrothermal datasets rely on such extremes in simulating climatic effects on building performance. Prior to 2012, WUFI employed customized 30-year hourly data provided by the U.S. Department of Energy for the 1961-1990 period of…

Climate Data for Building Simulations

Computer simulations rely on a variety of datasets when assessing the effects of climate on building performance.  These data, and the models they power, provide an important basis for planning, design, and cost analysis.  Below I describe some of the major types of climate datasets used in energy and hygrothermal modeling. Weather Years Datasets described…

Construction Documents

Quotes: Construction Documents

“It may be set as the glory of an architect’s specification, that it shall be so clear, that the builders who from it are estimating the probable cost of the intended work, may have to ask no questions; that the specification, shall contain and exact comprehensive and proper description of the work, as it really…
