POSSIBILITY OF CONSTRUCTING ZERO ENERGY BUILDING IN JAKARTA CITY

Introduction

A zero energy building (ZEB) produces enough renewable energy to meet its own annual energy consumption requirements, thereby reducing the use of non-renewable energy in the building sector. ZEBs use all cost-effective measures to reduce energy usage through energy efficiency and include renewable energy systems that produce enough energy to meet remaining energy needs. There are a number of long-term advantages of moving toward ZEBs, including lower environmental impacts, lower operating and maintenance costs, better resiliency to power outages and natural disasters, and improved energy security.

Reducing building energy consumption in new building construction or renovation can be accomplished through various means, including integrated design, energy efficiency retrofits, reduced plug loads and energy conservation programs. Reduced energy consumption makes it simpler and less expensive to meet the building’s energy needs with renewable sources of energy.

ZEBs have a tremendous potential to transform the way buildings use energy and there are an increasing number of building owners who want to meet this target. Private commercial property owners are interested in developing ZEBs to meet their corporate goals, and some have already constructed buildings designed to be zero energy. In response to regulatory mandates, federal government agencies and many state and local governments are beginning to move toward targets for ZEBs.

Building and designing affordable zero energy homes involves 12 integrated steps that utilize commonly available building materials and equipment along with easy-to-learn building strategies:

• Start with Smart Design, Cost-effective zero net energy homes begin with smart design. Designers and architects, as well as builders, should be familiar with all the steps involved in building a net zero home and should design the home so that builders and subcontractors can implement these steps as cost-effectively as possible. There are several design parameters to which builders should ask designers to pay special attention. Detailed communication between the builder and designer will ensure that these critical details don’t fall through the cracks
• Use Energy Modeling, During the design phase, the home’s energy use should be estimated using energy modeling software to ensure that the goal of net zero energy can be achieved while keeping costs down. Based on the results, design choices can be made or modified to balance building performance and construction cost.
