Acoustics in Wall and Ceiling Designs: The Critical Impact of Construction Details

The acoustical quality of a space is impacted by many factors, not the least of which are the construction of the walls and ceilings. This presentation will review both building science and design strategies, with a goal to impart a basic understanding of the factors that contribute to quality acoustics. A review of what to look for in the field during construction is also covered.

Proper Selection of Grilles, Registers, and Diffusers

This webinar provides the knowledge and skills needed to properly select registers, grilles and diffusers. You will be introduced to the importance of proper supply register selection on the dynamics of air mixing and room airflow.

The age-old debate of whether supply airflow or return airflow affects room comfort more will be examined as the characteristics of various grilles, registers and diffusers are discussed in detail. Face velocity, terminal velocity, throw, spread, degree of deflection, noise criteria, effective area, and free area will all be defined. The impact these properties have on the airflow performance of a register, grille, or diffuser will also be explained.

Proper sizing techniques and interpretation of manufacturer’s engineering data will be covered to aid in proper grille, register, and diffuser selection. Participants will learn practical application of this data to improve the performance of forced-air HVAC systems. This ability will allow access to hidden opportunity to HVAC professionals for added sales and the ability to provide additional solutions that most will overlook.

Reflective Roofs and Urban Heat Islands: Protecting People, the Environment, and the Economy

As buildings, roads, and parking lots replace open land and vegetation in and around cities, the resultant urban areas become significantly warmer, forming a “heat island” within the landscape. This webinar will discuss how urban heat islands pose a significant problem that may jeopardize the economy, the environment, public safety, and human health. The webinar also will review current approaches to address the consequences of heat islands, with an emphasis how reflective roofs offer the most feasible and cost-effective strategy. Finally, the webinar review important characteristics of reflective roofs to help the building designer optimize roof system design and selection in urban areas.

Product Disclosure: Opportunities and Challenges for the Building Designer

With the release of the latest green building standards and guidelines such as LEED v4, ASHRAE 189.1, and the 2015 International Green Building Code, product disclosure has become an important topic in sustainable building design.  Although disclosure offers an opportunity to move from guesswork to informed decision-making, it remains a work in progress, raising perhaps as many questions as answers.

In order to help the building designer resolve these questions, this webinar will provide a detailed review of the origins of the product disclosure concept, the market forces driving product disclosure, and the latest product disclosure criteria incorporated in building standards and codes. To accomplish this, the webinar will focus on two of the most talked-about disclosure tools: The Environmental Product Declaration (EPD) and the Health Product Declaration (HPD). The webinar will conclude with a discussion of how these new tools may impact the building designer and what strategies can be used to integrate these new tools into professional practice.

Roofs and Condensation: A Practical Approach for the Design Professional

The growth of single-ply roofing systems over the past 40 years has led to extensive research to validate and improve their long-term performance. Recently, as “cool” single-ply roofs have gained market attention, new questions have emerged in regard to vapor movement and the potential for moisture condensation. Starting with a discussion of the fundamentals of vapor movement in roofing systems, this webinar will review current research to gain understanding of the actual incidence of moisture condensation. Building on this research, the webinar will then identify the key factors that may lead to moisture accumulation in single-ply roofs. Finally, the webinar will provide practical suggestions for the roofing designer to avoid moisture condensation in modern commercial roofing systems.

BIM for Greener Interiors

Interior designers stand to benefit from BIM and BIM-compatible software just as much as architects and contractors. From highly accurate clash detection to reduced change orders to a much more streamlined design and construction process, BIM is poised to continue its upward trend from novelty to best practice, eventually becoming an industry standard.

Weather-Related Effects on Installation of Fully Adhered Single Ply Systems

Presentation on the relationship between temperature and dew point differentials and the impacts they may have on the performance of adhesives.  Two case studies will be evaluated along with supporting lab data to highlight the importance of understanding environmental conditions and the role they play in proper adhesive drying. 

Due to environmental concerns and code restrictions with solvent-based single ply adhesives, the use of water-based (WB) and low-VOC solvent-based (LVOC) adhesives is becoming much more popular in the low-slope roofing market. At the same time, the roofing industry has become concerned with the longer drying times exhibited by WB and LVOC products because both react differently to environmental conditions than solvent-based adhesives. This is especially true during changes in ambient temperatures and dew points up on the roof.

While there is a general industry consensus that most of these issues revolve around WB adhesive drying rates, it has been found that similar problems may also apply to LVOC adhesive products. These concerns have taken the form of blistering and/or inadequate adhesion of the single ply membrane to the substrate when using WB and LVOC adhesives in certain environmental conditions

Roofs and Condensation: A Practical Approach for the Design Professional - Article

The growth of single-ply roofing systems over the past 40 years has generated many questions regarding long-term performance.  Early in their development, many of the questions were related to the capability of single-ply systems to resist external forces such as wind, fire, and precipitation. However, with the advent of “cool” single-ply roofs, new questions have emerged concerning the internal forces at play within the roofing system, especially in regard to vapor movement and the potential for moisture condensation within the roof. Starting with a brief discussion of the fundamentals of vapor movement in roofing systems, this article reviews current research to gain an understanding of the actual incidence of moisture condensation and the key factors that may lead to moisture accumulation in single-ply roofs.

Continuous Insulation Requirements and Design for Water Vapor Diffusion Control

The architecture, engineering, and construction industry continues to require increasing thermal efficiency in wall assemblies, as reflected in evolving energy code requirements.  Many new exterior wall designs include a split insulation system to meet the demand for greater thermal efficiency.  As a result, the arrangement of insulation in walls relative to the air, water, and vapor barriers is also changing.  The need for, and proper location of, a vapor retarder in exterior walls with split insulation is often not intuitive and requires further analysis.  This presentation will discuss relevant code requirements for insulation, discuss water vapor diffusion and methods for evaluating condensation potential, and present best-practices for the selection and location of a vapor retarder.  We will also discuss construction considerations designers must negotiate to achieve acceptable thermal and hyrgothermal performance in contemporary exterior walls.
