Thermoactive Foundations for Sustainable Buildings

Momentum Press
Free sample

This monograph documents the current of state-of-art in Thermo-Active Foundations (TAFs) suitable for efficiently and sustainably heat and cooling buildings. TAFs, also referred to as thermal or energy piles, offer innovative and sustainable alternatives to ground-source heat pumps as well as other conventional heating, ventilating, and air conditioning (HVAC) systems to heat and cool commercial as well as residential buildings in several regions in the world. In summary, this monograph collects the latest multi-disciplinary advances in modeling, designing, and monitoring TAFs. Ultimately, it is hoped that this monograph will provide a comprehensive reference for both researchers and professionals interested in structural and thermal performance of TAFs and their applications in developing integrated and sustainable equipment and systems for the built environment.

Heating, Ventilation, Air Conditioning (HVAC) equipment is only as good as the installation.  Studies show that the majority of HVACR equipment is not installed to manufacturer specifications, costing the consumer more money.

* 68% of all air conditioning systems are improperly charged.
* 70% of all systems have improper airflow.
* 91% of systems remain untested for combustion safety and efficiency!  

The System Performance training manual is broken into four sections. Each section covers the techniques and procedures required for a technician to maximize the energy efficiency of HVAC systems.

1. Airflow: Covers the properties of air, airflow measuring tools, CFM calculations/requirements, blower performance, and sensible heat ratios.

2.Critical Charging: Reviews the three charging methods by weight, system superheat, and condenser subcooling.  It gives examples of calculating the total charge based on line sizes and provides an easy method to check whether a system is operating to rated capacity.

3.Psychrometrics: Covers the parts of a psychrometric chart and calculating the thermodynamic properties of air.  Also, this section demonstrates using wet and dry bulb temperatures to plot air conditions being heated or cooled which enables the technician to obtain a systems effect on sensible and latent building load.

4.Combustion Analysis: This section reviews the basic combustion process and the factors that affect heating efficiency.  Proper methods for furnace setting of airflow, adjustment and testing fuel pressure, and flue gas venting.
As the environmental impact of buildings become increasingly recognized, the role of building designers and the initial decision making process that determines materials, systems, and construction processes becomes more critical. This timely book addresses sustainability in building design through a series of examples presented as three dimensional models of well integrated building systems. The book organizes buildings into three sections – structure, envelope, and mechanical systems – based on the integration of paired building systems. The book demonstrates the performance of each systems pair in terms of interaction and contribution of each individual system and the synergetic benefits resulting from the unique pairing. The last section of the book is devoted to buildings that have a higher degree of integration and cannot be studied as paired systems. Each building is illustrated with full graphical display, text and analytical drawing to demonstrate its performance in a particular environment. 

Key Features: 

--Demonstrates the best practices and principles of designing and constructing buildings that are both environmentally responsible and architecturally expressive 

--Incorporates an innovative and unique approach for introducing and organizing building systems into categories based on pairing systems interaction and their performance rather than the traditional typological organization based on building systems 

--Presents the content as a catalogue of illustrated building systems, diagrams and details 

--Utilizes easy-to-understand axonometrics, concise narrative and graphics to illustrate building systems integration 

--Exposes the complex layers of the building components revealing the interworking of systems integration typically hidden in photographs

This book presents 18 in-depth case studies of net zero energy buildings—low-energy building that generate as much energy as they consume over the course of a year—for a range of project types, sizes, and U.S. climate zones. Each case study describes the owner’s goals, the design and construction process, design strategies, measurement and verification activities and results, and project costs.

With a year or more of post-occupancy performance data and other project information, as well as lessons learned by project owners and developers, architects, engineers, energy modelers, constructors, and operators, each case study answers the questions:

What were the challenges to achieving net zero energy performance, and how were these challenges overcome? How would stakeholders address these issues on future projects?

Are the occupants satisfied with the building? Do they find it comfortable? Is it easy to operate?

How can other projects benefit from the lessons learned on each project?

What would the owners, designers, and constructors do differently knowing what they know now?

A final chapter aggregates processes to engage in and pitfalls to avoid when approaching the challenges peculiar to designing, constructing, and owning a net zero energy building.

By providing a wealth of comparable information, this book which will flatten the learning curve for designing, constructing, and owning this emerging building type and improve the effectiveness of architectural design and construction.
