Building construction has gone for tremendous changes during the last decade. With the improvement in quality of life, earnings, living style, the building construction methodology and construction materials have been modified to suit the life style of people. The art of living has changed and human comfort is given a lot of importance. With the increase in electronic gadgets in the houses along with air conditioning system energy consumption becomes enormous. This paper highlights different insulation materials along with application specifications and confirmation to local Green Standards or Energy Codes in India.

Saudi Arabia has been in rapid growth in recent years which resulted in electricity consumption growth. Air-conditioners (A/Cs) are responsible for 50% of the electricity consumption due to hot weather conditions as well as the delay in implementing A/Cs performance standards. One of the challenges is that most of the installed A/Cs in existing buildings are old and have been installed before regulations and standards on A/Cs specifications were enforced in 2013. Renewing old A/Cs with new and efficient ones would reduce electricity consumption, benefiting building owners as well as utility companies.

Buildings consume more than 40% of energy in the U.S. Effectively and efficiently managing and controlling building energy and mechanical systems for a sustainable built environment remains a critical challenge. Studies shows intelligent building controls enable a greater than 20% energy savings in specific buildings, accounting for 2% of national energy consumption. Even small improvements in control system logic can make significant changes in energy savings over the course of a year or longer. How to develop, test and evaluate controller performances is crucial for scalable deployment of these control logics including load controls and distributed control solutions.

In a hospitality building, guests’ presence ratio (%) in the room is low due to the varying schedule and needs (business, shopping, sightseeing etc.) of individual guests. So, the energy consumption can be reduced during guests’ absence by turning the HVAC off for the room, but it can cause discomfort to the guest when they come back to the room. So it poses trade-off problems to maintain the comfort for the user and reduces the energy consumption at the same time in a hospitality building. This paper proposes an algorithm to solve the above-mentioned problem.

Religious facilities throughout the world are unique in their operation compared to other types of commercial buildings. Due to their lower energy intensity, these buildings rarely are the recipients of traditional energy studies or assessments. This paper presents highlights from a long-term energy study of two architecturally-identical churches located in different climates. Data were collected from over 130 sensors over an 18-month time period. This paper discusses how religious facilities differ from other types of commercial buildings in regards to occupancy, lighting, HVAC usage, and comfort.
